Special Issue Information

Dear Colleagues,

The inflammasome is an intracellular protein complex that provides a molecular platform for inflammatory responses to a variety of the pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs). The inflammasome is classified into canonical and noncanonical inflammasomes, and has been demonstrated to play a crucial role in inflammation and diseases. However, the roles of both canonical and noncanonical inflammasomes, as well as how their dysregulation contributes to inflammatory responses and diseases, are still not well understood and require further investigation.

This Special Issue aims to investigate the regulatory roles of both canonical and noncanonical inflammasomes in inflammation and diseases and to provide insights into the development of new anti-inflammatory therapeutics by targeting inflammasomes.

Potential topics include but are not limited to

  1. the roles of canonical and noncanonical inflammasomes in inflammatory responses and human diseases,
  2. the underlying mechanisms,
  3. identifying and validating novel molecules interplaying with inflammasomes,
  4. evaluating anti-inflammatory effects by targeting inflammasomes, and
  5. developing potential inflammasome-targeted therapeutics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Targeting the NLRP3 Inflammasome with Colchicine in COVID-19: Therapeutic Evidence and Future Implications for Influenza

Coronavirus disease 2019 (COVID-19) and influenza share key pathogenic mechanisms, including viral invasion, dysregulated innate immune activation, and the development of severe systemic complications. A central mediator of disease progression in both infections is the hyperactivation of the NLRP3 inflammasome, which drives excessive production of pro-inflammatory cytokines, immunothrombosis, multiorgan injury, and increased mortality. Colchicine possesses a unique pharmacokinetic property of preferential accumulation within myeloid cells, where sufficiently high intracellular concentrations inhibit NLRP3 inflammasome activation. This mechanism provides a biological rationale for preventing the cytokine storm and its downstream consequences when colchicine is administered early during infection. Available pharmacokinetic, toxicological, and clinical evidence suggests that loading doses of colchicine up to approximately 0.05 mg/kg body weight can be administered safely in appropriately selected patients, provided that clinically significant drug–drug interactions and hepatic or renal impairment are carefully excluded. The widely accepted belief that total doses of 7–7.5 mg are inherently lethal appears to reflect historical cases complicated by drug interactions and/or hepatic or renal impairment, rather than toxicity attributable to colchicine dose alone. These observations support reconsideration of current guideline recommendations regarding colchicine dosing. In particular, cumulative doses below 0.1 mg/kg appear to be consistently safe, whereas doses between 0.1 and 0.2 mg/kg are associated with only a low risk of toxicity and rarely with severe intoxication. Reassessment of colchicine dosing strategies may therefore be warranted to optimize NLRP3 inflammasome inhibition and improve outcomes in patients with COVID-19 and influenza. Full article

Inflammation is an innate immune system protecting the body from infection and injury. This process proceeds through two distinct stages: a priming phase, characterized by transcriptional activation, and a triggering phase, in which inflammasomes, cytosolic multiprotein complexes, are activated to initiate inflammatory signaling cascades. Canonical inflammasomes, the first to be identified, have been extensively implicated in the pathogenesis of diverse inflammatory disorders. In contrast, noncanonical inflammasomes have only recently been characterized, and their precise contributions to immune regulation and disease development remain incompletely defined. Diabetes mellitus (DM), simply diabetes, represents a heterogeneous group of metabolic disorders marked by chronic hyperglycemia and is associated with a broad spectrum of complications. The involvement of canonical inflammasomes in DM and its complications has been well demonstrated. More recently, however, accumulating evidence has uncovered crucial roles for noncanonical inflammasomes in the pathogenesis of DM and related complications This review comprehensively discusses current advances in understanding the regulatory functions of murine caspase-11 and human caspase-4/5 noncanonical inflammasomes in the pathogenesis of DM and diabetes-associated complications, highlighting their potential as novel therapeutic targets.
