Background: Bimekizumab, secukinumab, and ixekizumab are IL-17-targeting biologics approved for the treatment of moderate-to-severe plaque psoriasis. While secukinumab and ixekizumab selectively inhibit IL-17A, bimekizumab targets both IL-17A and IL-17F, potentially providing greater anti-inflammatory efficacy. This study aimed to compare the real-world effectiveness, safety, and tolerability of these agents in a Polish dermatology center between 2019 and 2024. Methods: We conducted a retrospective analysis of 98 patients meeting at least one of the following criteria: PASI ≥ 10, BSA ≥ 10, DLQI ≥ 10, or involvement of special areas with inadequate response or contraindications to ≥2 systemic therapies. Patients with prior exposure only to IL-17 inhibitors were excluded. PASI, BSA, and DLQI scores were recorded at baseline, week 4, and week 12. Due to differences in dosing schedules, outcomes were aligned using standardized timepoints and exponential modeling of continuous response trajectories. Mixed-effects ANOVA was used to assess the influence of baseline factors (age, BMI, PsA status) on treatment outcomes. Adverse events were documented at each monthly follow-up visit. Results: Bimekizumab showed the greatest effect size for PASI reduction (Hedges’ g = 3.662), followed by secukinumab (2.813) and ixekizumab (1.986). Exponential modeling revealed a steeper response trajectory with bimekizumab (intercept = 0.289), suggesting a more rapid PASI improvement. The efficacy of bimekizumab was particularly notable in patients who were previously treated with IL-23 inhibitors. All three agents demonstrated favorable safety profiles, with no serious adverse events or discontinuations. The most frequent adverse events were mild and included upper respiratory tract infections and oral candidiasis. Conclusions: This real-world analysis confirmed that IL-17 inhibitors effectively improved PASI, BSA, and DLQI scores in moderate-to-severe psoriasis. Bimekizumab demonstrated the most rapid early improvements and a higher modeled likelihood of complete clearance, without significant differences at week 12. All agents were well tolerated, underscoring the need for further individualized, large-scale studies. Full article

Background: Immune checkpoint inhibitors (ICIs) have transformed cancer treatment, yet severe immune-related adverse events (irAEs) often necessitate immunotherapy discontinuation and cause life-threatening complications. Circulating plasma proteins, dynamically accessible and functionally linked to immunity, may predict and offer novel targets for irAEs. Methods: Leveraging multi-omics integration, we conducted bidirectional two-sample Mendelian randomization (MR) using protein quantitative trait loci (pQTLs) from 4998 plasma proteins and genome-wide association data of irAE phenotypes. A causal inference framework combining colocalization analysis, multivariable MR (MVMR) adjusting for body mass index (BMI) confounding, and mediation MR elucidated BMI-independent pathways. Systems biology approaches including tissue-specific expression profiling, pathway enrichment, and protein interaction network analysis revealed spatial and functional drivers of irAE pathogenesis. Results: Proteome-wide MR mapping identified eight plasma proteins (CCL20, CSF1, CXCL9, CD40, TGFβ1, CLSTN2, TNFSF12, TGFα) causally associated with all-grade irAEs, and five (CCL20, CCL25, CXCL10, ADA, TGFα) with high-grade irAEs. Colocalization prioritized CD40/TNFSF12 (all-grade) and ADA/CCL25 (high-grade) as therapeutic targets (PPH4 > 0.7). CXCL9/TNFSF12 (all-grade) and CCL25 (high-grade) exerted BMI-independent effects, suggesting intrinsic immune dysregulation mechanisms. Tissue-specific gene expression patterns, CSF1, TGFβ1 in lung, TNFSF12 in the ileum may explain organ-specific irAE vulnerabilities. High-grade irAEs correlated with compartmentalized immune dysregulation and IL-17/immunodeficiency pathway activation. Conclusions: This study establishes the causal atlas of plasma proteins in irAE pathogenesis, bridging biomarker discovery with actionable therapeutic targets. These advances align with next-generation immunotherapy goals: maximizing efficacy while taming the immune storm. Full article

Interleukin-23 (IL-23) is a key cytokine involved in the pathogenesis of various immuno-mediated inflammatory diseases. In recent years, several drugs selectively targeting IL-23 have been developed and three of them (mirikizumab, risankizumab and guselkumab) were successfully investigated in clinical trials for ulcerative colitis (UC). All of them showed a good profile for efficacy, alleviating symptoms, and inducing endoscopic and histologic improvement, with very low incidence of adverse events. Bowel urgency also emerged as a crucial outcome from patients’ perspective in the mirikizumab trials. The correct positioning of IL-23 inhibitors in the therapeutic algorithm for UC represents a new challenge for physicians, especially because it is not guided by biomarkers or predictors of effectiveness. Moreover, no comparative clinical data exist among the available IL-23 inhibitors, although molecular differences might potentially impact their effectiveness. A role for IL-23-inhibitors may also lie in combination with drugs with different mechanisms of action for complex, multi-refractory patients. This review, focusing on UC, summarizes all the clinical data available on IL-23 inhibitors and provides a perspective on the best clinical scenarios to maximize their effectiveness. Full article

Background/Objectives: Psoriatic arthritis (PsA) is a chronic inflammatory condition that primarily affects the musculoskeletal system and skin. While biologic and targeted synthetic DMARDs have improved treatment, many patients still fail to achieve remission. Combining conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) with biologic (b) DMARDs or targeted synthetic (ts) DMARDs shows no added benefit over monotherapy with IL-17, IL-23 inhibitors, or JAK inhibitors, unlike TNFi, which benefit from csDMARD co-administration. Guselkumab (GUS) and risankizumab (RKZ) target IL-23 with high specificity. RCTs (DISCOVER 1 and 2, COSMOS) have confirmed GUS efficacy regardless of methotrexate (MTX) use, though liver toxicity was higher with MTX. Real-world data on GUS remain limited, with gaps in understanding its long-term effectiveness and drug survival. The aim of this study is to assess the following three points within a multicenter Italian real-life cohort of PsA patients treated with guselkumab (GUS) and followed for 12 months: (1) effectiveness and safety of GUS; (2) drug retention rate (DRR) and reasons for discontinuation; (3) impact of comorbidities on achieving minimal disease activity (MDA). Methods: This study utilized data from the GISEA registry, which includes centers in different parts of Italy (north, center, south, and islands), and included patients aged 18 and older diagnosed with PsA according to the CASPAR criteria. Results: Data on 170 PsA patients treated with GUS were collected. In the first 6 months, a prompt mean percentage improvement in all clinimetric indexes was observed compared to the baseline. At 6-month follow-up, ACR 20 was reached by 60% of patients, ACR 50 by 30%, ACR 70 by 15%, MDA by 28%, and DAPSA < 14 by 50% of patients in the overall group. Significant differences were found in the rate of ACR 50 in the bDMARD-naive group (50%) compared to one bDMARDs non-responder (NR) (8%) (p = 0.021). At 12-month follow-up, a notable gap was observed in the rate of patients reaching MDA between bDMARD-naive (60%) and one bDMARDs NR (22%) (p = 0.035) and between bDMARD-naive (60%) and ≥2 bDMARDs NRs (22%) (p = 0.024). By using multivariate binary logistic analysis, the predictors of reaching MDA at 12-month follow-up were naive bDMARDs (OR: 7.9, 95% CI: 1.3–44.8, p = 0.019) and a higher value of pGA at baseline (OR: 1.1, 95% CI: 1–1.5; p = 0.046). The presence of comorbidities, including fibromyalgia and obesity, did not seem to affect the reaching of MDA. At 12-month follow-up, the GUS retention rate was 76%, with a mean survival time of 10.5 months ± 0.2 (95% CI: 10–10.9). No significant differences in GUS survival time were found among bDMARD-naive, one bDMARDs NR, and ≥2 bDMARDs NR patients (in the latter, regardless of the previous mechanism of action: TNFi or other mechanism), as well as between patients treated with GUS in monotherapy and those treated in combination with csDMARDs. A low rate (17%) of discontinuation was found due to both primary NR and secondary NR. The high safety of GUS was recorded. In fact, discontinuation due to adverse events (all definable as minor) was observed in just 4% of patients. By using COX regression multivariate analysis, the factors associated with higher GUS discontinuation risk were a more severe baseline PASI (HR: 1.05, 95% CI: 1–1.1, p = 0.038) and higher baseline ESR (HR:1.06, 95% CI: 1–1.03, p = 0.05). Conclusions: Good performance of GUS was observed in both biologic-naive patients and those with failure of previous bDMARDs (regardless of the mechanism of action of the previous drug: TNFi or non-TNFi), presenting good persistence in therapy even when used as a third mechanism of action. Its high safety profile allows the use of GUS even in particularly complex patients. Full article

Background/Objectives: Cutaneous side effects are the most common immune-related adverse events (irAEs) caused by immune checkpoint inhibitors (ICIs) and affect 70–90% of patients. Besides diverse types of exanthema, rare skin toxicity includes bullous dermatoses in 0.3% of cases. Systemic steroids are the first-line treatment for immune-related bullous pemphigoid (irBP); however, some cases are corticosteroid-resistant. IrBP is one of the irAEs most frequently chronic and associated with long-term steroid use. However, steroids may interfere with tumor response. Therefore, alternative treatment strategies for irBP are desperately needed. Dupilumab, a monoclonal antibody blocking the receptor binding of interleukin-4 (IL-4) and interleukin-13 (IL-13), has been successfully used to treat spontaneous forms of bullous pemphigoid (BP). In this study, we analyzed the gene expression profiles of BP and irBP. Patients and Methods: A retrospective multicenter study evaluated the gene expression profiles of irBP and BP in comparison to healthy controls. Gene expression analyses of skin biopsies were performed using NanoString technology from patients with BP (n = 17), irBP (n = 19), and healthy skin (n = 24) after the patients had consented to participate in this study, and differentially expressed genes (DEGs) were determined using Rosalind software. Results: Compared to healthy skin, BP showed 167 DEGs, and irBP revealed 99 DEGs. Some of the DEGs from irBP and BP vs. healthy skin overlapped. Specifically, IL-4- and IL-13-associated genes were upregulated in both irBP and BP compared to healthy skin. Interestingly, expression profiles of BP vs. irBP also showed 13 DEGs. Conclusions: These findings suggest a possibility for therapeutic efficacy of IL-4 and IL-13 inhibitors in the treatment of irBP. Full article

Crohn’s disease (CD) is a chronic inflammatory condition of the digestive tract, driven by an imbalance in immune system regulation, where proinflammatory interleukin-23 (IL-23) plays an essential role. Selective new IL-23 inhibitors, including risankizumab, guselkumab, and mirikizumab, block the IL-23p19 subunit to inhibit the Il-23 action and alleviate inflammation in CD. This review explores the effectiveness, safety, and therapeutic potential of anti-IL-23 treatment in CD management. Risankizumab, guselkumab, and mirikizumab demonstrated considerable effectiveness in inducing clinical remission and promoting endoscopic healing in patients with moderately to severely active CD, including those refractory to anti-TNF therapies. Risankizumab showed favorable results in pivotal trials like ADVANCE, MOTIVATE, and FORTIFY, achieving remission rates of up to 45% and sustained inflammatory biomarkers normalization. Guselkumab and mirikizumab similarly demonstrated substantial efficacy in the induction and maintenance phases, with promising long-term results. The safety profiles of IL-23 inhibitors were favorable, with low rates of serious adverse events, including infections and malignancies. Selective new IL-23 inhibitors represent a targeted and effective therapeutic class for moderately to severely active CD, offering high clinical and endoscopic remission rates, and favorable safety outcomes. Continued research, particularly on long-term efficacy and the selection of patients based on inflammatory biomarkers, will help optimize their role in personalized treatment strategies for refractory CD.

Deucravacitinib is an allosteric, selective tyrosine kinase 2 (TYK2) inhibitor that has demonstrated significant efficacy in the treatment of psoriasis. TYK2, a member of the Janus kinase (JAK) family, plays a critical role in intracellular signaling pathways for pro-inflammatory cytokines. Unlike traditional JAK inhibitors, which target active domains, deucravacitinib selectively binds to the pseudokinase domain of TYK2. This binding induces a conformational change that locks the enzyme in an inactive state, ensuring superior selectivity for TYK2 over JAK 1/2/3. This unique mechanism specifically inhibits key pro-inflammatory cytokines, including IL-12, IL-23, and type I interferons, critical in the pathogenesis of psoriasis and other immune-mediated diseases. As a result, deucravacitinib represents a promising option for targeted therapy in immune-mediated diseases and may reduce adverse events commonly associated with broader immunosuppressive treatments. Furthermore, its oral administration offers a convenient alternative to injectable biologics, potentially improving patient adherence and treatment satisfaction. This review highlights recent studies suggesting that deucravacitinib may also have therapeutic benefits in psoriatic arthritis, palmoplantar pustulosis, systemic lupus erythematosus, Sjogren’s disease, and inflammatory bowel disease. Given its expanding therapeutic potential, deucravacitinib may provide a safer and more effective alternative to current therapies, offering a tailored approach to treatment. Full article

Background: Within the past few years, many new therapies have emerged for psoriasis and psoriatic arthritis (PsA). Current topical therapies—including corticosteroids, vitamin D analogs, tapinarof, and roflumilast—remain the mainstay for mild disease, while oral systemic and biologic options are for moderate to severe cases. Biologics—such as Tumor necrosis factor-alpha (TNF-alpha), Interleukin 12/23 (IL-12/23), Interleukin-17 (IL-17), and Interleukin-23 (IL-23)—have revolutionized care by providing highly effective and safer alternatives. Oral small molecules, including Janus kinase (JAK) and tyrosine kinase 2 (TYK2) inhibitors, further expand the therapeutic options. Objectives: The goal for this review article was to examine current and latest treatments for psoriasis and PsA and discuss whether these emerging therapeutic options address the unmet needs of current treatments. Methods: The search for this review article included PubMed, Google Scholar, and ClinicalTrials.gov for relevant articles and current clinical trials using keywords. Results: A wide range of novel psoriatic and PsA therapies are currently undergoing clinical trials. These include selective JAK inhibitors, TYK2 inhibitors, retinoic acid-related orphan receptor (RORγT) inhibitors, oral IL-23 receptor inhibitors, oral IL-17A inhibitors, nanobody products, sphingosine-1-phosphate (S1P1R) antagonists, A3 adenosine receptor (A3AR) agonists, heat shock protein (HSP) 90 inhibitors, and rho-associated protein kinases (ROCK-2) inhibitors. Conclusions: These different mechanisms of action not only expand treatment options but may offer potential solutions for patients who do not achieve adequate response with existing therapies. However, the safety and contraindications of these newer agents remain an important consideration to ensure appropriate patient selection and minimize potential risks. Certain mechanisms may pose increased risks for infection, cardiovascular manifestations, malignancy, or other immune-related adverse events, necessitating careful monitoring and individualized treatment decisions. Ongoing clinical research aims to address unmet needs for patients who do not respond to previous agents to achieve sustained remission, monitor long-term safety outcomes, and assess patient preferences for delivery, including a preference for oral delivery. Oral IL-23 inhibitors hold potential due to their robust safety profiles. In contrast, oral IL-17 inhibitors and TYK-2 inhibitors are effective but may present side effects that could impact their acceptability. It is essential to balance efficacy, safety, and patient preferences to guide the selection of appropriate therapies. Full article

Metabolic syndrome (MetS) can contribute to a chronic ischemia-relative overactive bladder (OAB). Using fructose-fed rats (FFRs), a rat model of MetS, we investigated the effects of tadalafil (a phosphodiesterase-5 inhibitor) on MetS-associated chronic bladder ischemia and bladder overactivity. Phenotypes of the OAB, including increased micturition frequency and a shortened intercontractile interval in cystometry, were observed in FFRs, together with reduced bladder blood perfusion (in empty bladders) via laser color Doppler imaging and elevated serum nitrite levels, suggesting chronic ischemia-related bladder dysfunction. Treatment with tadalafil (2 mg/kg) promoted pelvic angiogenesis, as shown by magnetic resonance imaging, and increased VEGF and p-eNOS overexpression in the bladder. This treatment restored bladder perfusion and alleviated bladder overactivity without significantly altering most MetS parameters. At the molecular level, FFRs exhibited increased ischemia markers (NGF, HIF-2α, and AMPK-α2) and decreased p-AMPK-α2, along with elevated proinflammatory mediators (ICAM-1, nuclear NF-κB, COX-2, IL-1β, IL-6, and TNF-α), enhanced mitochondria biogenesis (PGC-1α, TFAM, and mitochondria DNA copy number), oxidative stress (decreased nuclear NRF2, increase MnSOD and 8-OHdG staining), and tissue fibrosis (increased TGF-β1, collagen I, and fibronectin). Tadalafil treatment improved these effects. Together, these findings suggest that tadalafil may promote VEGF-associated angiogenesis, enhance p-eNOS staining in the bladder vasculature, normalize bladder perfusion in microcirculation, and reduce serum nitrite levels. Consequently, tadalafil mitigates the adverse effects of chronic ischemia/hypoxia, improving bladder overactivity. We elucidated the mechanisms underlying the tadalafil-mediated amelioration of MetS-associated OAB symptoms. Full article

Introduction: Psoriasis (PSO) and atopic dermatitis (AD) have traditionally been considered distinct diseases, respectively, mediated by T-helper 1 (Th1) and the T-helper 2 (Th2) immune pathway. In recent years, there has been a growing body of evidence highlighting an overlap between the two conditions, such as Asian AD, pediatric PSO, or “psoriasis dermatitis/PSOREMA”. Moreover, psoriasis dermatitis can be induced by therapeutic interventions. For instance, anti-IL-4/IL-13 monoclonal antibodies, commonly used to treat AD, can induce psoriasiform reactions by inhibiting the Th2 pathway, thereby unmasking Th1/Th17-driven PSO. Conversely, anti-TNFα and anti-IL-17 therapies, effective for PSO, may induce eczematous reactions promoting a switch toward Th2-driven inflammation. Janus Kinase Inhibitors (JAK-i) and IL-23 antagonists may represent valid therapeutic options for managing psoriasis dermatitis. JAK-i exert broader immunomodulatory effects, inhibiting both Th1 and Th2 pathways; however, they require careful monitoring due to potential adverse events. In contrast, IL-23 antagonists specifically suppress the IL-23/IL-17 axis inhibiting the p19 subunit of IL-23 and could represent a safer option for patients with psoriasis dermatitis. Materials and Methods/Results: We present a series of five cases of psoriasis dermatitis, including both patients who had the condition from the onset and those who developed it during treatment, with tailored therapeutic strategies based on individual patient profiles, comorbidities, and the specific characteristics of their overlapping disease presentation. Conclusion: JAK-i and IL-23 antagonists are both valid therapeutic options for managing psoriasis dermatitis, but with different immunomodulatory effects and safety profiles. Future research should focus on a better understanding of the immune pathway and identifying specific biomarkers of psoriasis dermatitis, to optimize therapeutic strategies. Full article

Effective cancer therapies must address the tumor microenvironment (TME), a complex network of tumor cells and stromal components, including endothelial, immune, and mesenchymal cells. Durable outcomes require targeting both tumor cells and the TME while minimizing systemic toxicity. Interleukin-2 (IL-2)-based therapies have shown efficacy in cancers such as metastatic melanoma and renal cell carcinoma but are limited by severe side effects. Innovative IL-2-based immunotherapeutic approaches include immunotoxins, such as antibody–drug conjugates, immunocytokines, and antibody–cytokine fusion proteins that enhance tumor-specific delivery. These strategies activate cytotoxic CD8⁺ T lymphocytes and natural killer (NK) cells, eliciting a potent Th1-mediated anti-tumor response. Modified IL-2 variants with reduced Treg cell activity further improve specificity and reduce immunosuppression. Additionally, IL-2 conjugates with peptides or anti-angiogenic agents offer improved therapeutic profiles. Combining IL-2-based therapies with immune checkpoint inhibitors (ICIs), anti-angiogenic agents, or radiotherapy has demonstrated synergistic potential. Preclinical and clinical studies highlight reduced toxicity and enhanced anti-tumor efficacy, overcoming TME-driven immune suppression. These approaches mitigate the limitations of high-dose soluble IL-2 therapy, promoting immune activation and minimizing adverse effects. This review critically explores advances in IL-2-based therapies, focusing on immunotoxins, immunocytokines, and IL-2 derivatives. Emphasis is placed on their role in combination strategies, showcasing their potential to target the TME and improve clinical outcomes effectively. Also, the use of IL-2 immunocytokines in “in situ” vaccination to relieve the immunosuppression of the TME is discussed. Full article

Background: the present multicenter retrospective study aimed to evaluate the efficacy and safety of intra-class switching between interleukin-17A (IL-17A) inhibitors, specifically from ixekizumab to secukinumab, in patients with plaque psoriasis. Methods: this study included 11 patients (6 male, 5 female) who had previously received ixekizumab and then were switched to secukinumab. Patients’ PASI, DLQI, and pain VAS (in those with psoriatic arthritis) were evaluated at weeks 16, 24, 54, and 98. Results: PASI-90 was reached in 10 (91%) cases at week 24. One patient experienced secondary failure to secukinumab at week 98. No adverse events were reported. Conclusions: overall, the majority of patients experienced a favorable response to secukinumab, suggesting that it may be an effective treatment option for patients with an inadequate response or loss of efficacy to ixekizumab.

Gestational diabetes mellitus is characterised by an insufficient insulin response to hyperglycaemia and the development of insulin resistance. This state has adverse effects on the health outcomes of the mother and child. Existing hyperglycaemia triggers a state of inflammation that involves several tissues, including the placenta. In this study, we analysed the putative pathomechanism of GDM, with special emphasis on the role of chronic, sterile, pro-inflammatory pathways. The expression and regulation of the elements of IL-1β and Toll-like receptor (TLR) pathways in GDM maternal blood plasma, healthy placental explants and a choriocarcinoma cell line (BeWo cell line) stimulated with pro-inflammatory factors was evaluated. Our results indicate elevated expression of the IL-1β and TLR pathways in GDM patients. After stimulation with IL-1β or LPS, the placental explants and BeWo cell line showed increased production of pro-inflammatory IL-6, TNFa and IL-1β together with increased expression of the elements of the signalling pathways. The application of selected inhibitors of NF-ĸB, MAPK and recombinant interleukin 1 receptor antagonist (IL1RA) proved the key involvement of the IL-1β pathway and TLRs in the pathogenesis of GDM. Our results show the possible existence of loops of autocrine stimulation and a possible inflammatory pathomechanism in placentas affected by GDM. Full article

Rheumatoid arthritis (RA) patients face different health challenges when infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) than the general population, due to both their immunocompromised state and the immunosuppressive therapies they receive. This systematic literature review, which follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) paradigm, explores the interactions between RA and SARS-CoV-2 infection, focusing on immunologic issues, disease management, vaccination, and adverse outcomes. In order to obtain the most relevant information, we systematically reviewed the specific literature from 1 January 2021 to 31 December 2023, based on the PRISMA method, by which we eventually selected 35 eligible articles, to which we added other ISI-indexed studies to enrich our results further. Consequently, we performed a funnel analysis to evaluate the potential for publication bias. Firstly, the data collected revealed the impact of the pandemic on RA diagnoses and the fear of face-to-face medical consultations that delayed adequate treatment. Secondly, cardiovascular and metabolic comorbidities increase the risk of prolonged COVID-19 symptoms, hospitalization, and severe COVID-19 outcomes for RA patients. With respect to immunosuppressive treatment used to control RA, it was observed that glucocorticoids (especially high-dose usage) and Rituximab (RTX) predispose the patients to poor SARS-CoV-2 outcomes, as opposed to Baricitinib and interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) inhibitors. COVID-19 vaccination has proven effective and generally safe for RA patients in some studies, although therapies with Methotrexate (MTX), Abatacept (ABA), and RTX have been associated with impaired vaccine immune response. This systematic literature review brings updated and thorough information with respect to the immunological, clinical, and management of a complex immune-mediated inflammatory disease (IMID) like RA in the setting of COVID-19 and underlines the challenges faced by this group of patients. The lessons learned can be extended beyond the pandemic in shaping a more informed and compassionate healthcare system and offering long-term medical care for patients with RA. Full article

The landscape of clinical management for metastatic melanoma (MM) and other solid tumors has been modernized by the advent of immune checkpoint inhibitors (ICI), including programmed cell death-1 (PD-1), programmed cell death-ligand 1 (PD-L1), and cytotoxic T lymphocyte antigen 4 (CTLA-4) inhibitors. While these agents demonstrate efficacy in suppressing tumor growth, they also lead to immune-related adverse events (irAEs), resulting in the exacerbation of autoimmune diseases such as rheumatoid arthritis (RA), ulcerative colitis (UC), and Crohn’s disease (CD). The immune checkpoint inhibitors offer promising advancements in the treatment of melanoma and other cancers, but they also present significant challenges related to irAEs and autoimmune diseases. Ongoing research is crucial to better understand these challenges and develop strategies for mitigating adverse effects while maximizing therapeutic benefits. In this manuscript, we addressed this challenge using network-based approaches by constructing and analyzing the molecular and signaling networks associated with tumor-immune crosstalk. Our analysis revealed that IL6 is the key regulator responsible for irAEs during ICI therapies. Furthermore, we conducted an integrative network and molecular-level analysis, including virtual screening, of drug libraries, such as the Collection of Open Natural Products (COCONUT) and the Zinc15 FDA-approved library, to identify potential IL6 inhibitors. Subsequently, the compound amprenavir was identified as the best molecule that may disrupt essential interactions between IL6 and IL6R, which are responsible for initiating the signaling cascades underlying irAEs in ICI therapies.
