Hantaviruses (HTVs) are lethal zoonotic pathogens responsible for hemorrhagic fever with renal syndrome and HTV cardiopulmonary syndrome; however, no specific antiviral treatments or vaccines have been approved. Bee products, such as propolis, honey, royal jelly, bee venom, and bee pollen, demonstrate extensive antiviral, anti-inflammatory, antioxidant, and immunomodulatory properties against various RNA and DNA viruses. No published research has directly evaluated bee products in relation to HTV infection. This review proposes a hypothesis-driven mechanistic framework suggesting that bioactive compounds from bee products may concurrently inhibit HTV replication, alleviate the cytokine storm, diminish oxidative stress, and maintain endothelial barrier integrity. We explicitly recognize the lack of direct experimental evidence regarding bee products’ efficacy against HTVs. Considering the mechanistic similarities with other enveloped viral infections and the recognized functions of NF-κB, Nrf2, and endothelial signaling pathways in HTV pathogenesis, we present a scientifically substantiated rationale for forthcoming research endeavors. The diverse bioactive compounds present in bee products including bee pollen, bee venom, honey, propolis, and royal jelly could provide a multifaceted strategy for inhibiting HTV pathology. We propose systematic in vitro, in silico, and in vivo investigations to assess the potential of bee-derived flavonoids, peptides, and fatty acids as adjunctive therapeutic strategies for HTV disease.

Background/Objectives: Immunonutrition uses dietary bioactive compounds to support immune function while preserving systemic physiological balance. Donkey milk, bovine colostrum, and royal jelly contain complementary antimicrobial, immunoglobulin-rich, and immunoregulatory components, but their combined effects remain insufficiently characterized. Methods: A 6-week controlled study was conducted in female rabbits assigned to four groups (n = 15/group): vaccinated only (G1), immunonutraceutical only (G2), vaccination plus immunonutraceutical (G3), and pre-conditioned immunonutraceutical followed by vaccination and continued supplementation (G4). Serum total immunoglobulins and lysozyme were measured longitudinally. Biochemical indices were monitored throughout the study, and hematological parameters were evaluated at the final time point. Mixed-effects models, generalized estimating equations, principal component analysis, and correlation-based systems analyses were applied. Results: Supplementation significantly modulated both humoral and innate immune responses. The strongest terminal immunoglobulin response was observed in G4 (26.00 ± 5.80 mg/mL), whereas sustained lysozyme elevation was most pronounced in supplemented groups, particularly G3 (3.13 ± 0.44 ng/mL). Within-subject analysis demonstrated significant innate–adaptive immune coherence (p = 0.000006). Biochemical analyses showed coordinated metabolic adaptation without evidence of organ toxicity, and hematological findings indicated preserved inflammatory and hematopoietic stability. Conclusions: Multi-component immunonutraceutical supplementation modulated humoral and innate immune dynamics in a timing-dependent manner while maintaining biochemical and hematological safety. These findings support the potential of combined donkey milk, bovine colostrum, and royal jelly as functional ingredients for coordinated immune support. Full article

Colorectal cancer (CRC) remains a leading cause of cancer-related death worldwide, and advanced disease continues to show poor prognosis due to therapeutic limitations and drug resistance. Royal jelly (RJ), a natural functional food and dietary supplement, contains 10-hydroxy-2-decenoic acid (10-HDA), a bioactive fatty acid unique to RJ with demonstrated anticancer potential. This study evaluated the anti-CRC effects and underlying mechanisms of 10-HDA through cellular, animal, and transcriptomic approaches. 10-HDA markedly suppressed CRC cell viability with IC₅₀ of 2.07 mM and 3.49 mM against HCT 116 and HT-29 cells, respectively, reduced gap closure by 29.30%, elevated intracellular reactive oxygen species (ROS), and attenuated xenograft tumor growth dose-dependently. Preliminary safety evaluation suggested that 10-HDA was well tolerated under the tested conditions, with no significant changes in body weight, serum AST, ALT, or ALP levels, or organ histology. Transcriptomic analysis showed significant enrichment of apoptosis and Wnt/β-catenin pathways. Molecular assessments indicated that 10-HDA was associated with alterations in apoptosis-related features, including increased caspase-3 activity, changes in Bcl-2 family proteins, and elevated ROS levels, as well as with modulation of the Wnt/β-catenin signaling pathway. These changes were consistent with enhanced β-catenin degradation and reduced nuclear translocation. It suggests that Wnt/β-catenin may be involved in the anti-CRC effects of 10-HDA. This study mechanistically clarifies the anti-CRC activity of 10-HDA as a natural food-derived bioactive compound, suggesting its therapeutic potential for Wnt/β-catenin dysregulated CRC.

This work focused on the identification of angiotensin I-converting enzyme (ACE) inhibitory peptides from royal jelly (RJ) proteins and elucidated their inhibition patterns and mechanisms. RJ proteins were analyzed for ACE inhibition potential using in silico tools, and suitable enzymes were selected for peptide release. Hydrolysis conditions were optimized using response surface methodology (RSM), and the resulting peptides were fractionated and purified. Mass spectrometry identified 57 peptides, with seven selected for synthesis based on scoring. IDFDF, DVNFR, and SFHRL showed the highest ACE inhibition, with IC₅₀ values of 16.9 μM, 42.5 μM, and 242.6 μM, respectively. Lineweaver–Burk plots revealed IDFDF as a competitive inhibitor, DVNFR as a non-competitive inhibitor, and SFHRL as a mixed inhibitor. Molecular docking indicated that peptide–ACE interactions were primarily mediated through hydrogen bonds and Zn(II) coordination. This work promotes the sustainable utilization of RJ and the development of ACE inhibitory peptides derived from food sources. Full article

The present study investigates the role of royal jelly as a natural endocrine modulator of serum estradiol levels in juvenile sterlets (Acipenser ruthenus), a species of major interest for sustainable aquaculture. The experiment was conducted over a period of 85 days under controlled recirculating system conditions, using four dietary treatments (n = 30 fish per group): a control group and three groups supplemented with 1%, 3%, and 5% royal jelly. Serum estradiol concentrations were determined by high-performance liquid chromatography (HPLC), while biometric assessment included the determination of total length (L), standard length (Sl), maximum body height (H), body circumference (C), and body mass (BM). Royal jelly supplementation significantly increased serum estradiol levels in a dose-dependent manner (p < 0.05), with the highest values recorded in the 5% group compared to the control. The proportion of individuals with non-detectable estradiol levels decreased progressively with increasing supplementation level. Biometric analysis revealed moderate effects on growth parameters, with no statistically significant differences among groups for most traits (p > 0.05), except for maximum body height, which showed a significant overall effect (ANOVA, p = 0.0089). Principal Component Analysis (PCA) highlighted the relative independence between endocrine variability and growth dynamics. Overall, the findings support the potential of royal jelly as a natural endocrine modulator of serum estradiol, representing a promising and environmentally friendly alternative to synthetic hormonal substances used in aquaculture. This approach may contribute to the development of innovative nutritional strategies for endocrine control and the optimization of biological performance in sturgeons, in accordance with the principles of sustainable aquaculture.

Background: Wound healing remains a major clinical challenge, often impaired by persistent inflammation, oxidative stress, and abnormal extracellular matrix remodeling. Electrospun nanofibers (NFs) have emerged as promising wound dressing platforms due to their biomimetic structure and capacity to incorporate multiple bioactive compounds (ACs) with synergistic therapeutic effects. Objectives: This study aimed to biologically assess novel chitosan/poly(vinyl alcohol) (CH/PVA) NFs functionalized with natural active compounds (L-arginine—ARG, allantoin—ALA, royal jelly—RJ, and curcumin—CUR) as multifunctional systems for wound healing and tissue remodeling. Methods: The nanofibrous systems performed the in vitro evaluation of antioxidant activity (DPPH, ABTS, FRAP, PRAP), anti-inflammatory potential (protein denaturation test), hemocompatibility, and cytocompatibility using dermal fibroblasts. In vivo healing performance was evaluated in an excisional wound model using macroscopic wound contraction analysis, histopathology, and immunohistochemical staining (MMP-9, CD31, VEGF-A, α-SMA). Results: The bioactive-enriched CH/PVA NFs exhibited strong antioxidant and anti-inflammatory activity, excellent hemocompatibility (hemolysis < 5%), and excellent cytocompatibility, with promoting fibroblast proliferation. In vivo experiments revealed that the treated groups exhibited accelerated wound closure, improved re-epithelialization, increased angiogenesis, and showed more efficient tissue remodeling compared to the controls, as validated by histological and immunohistochemical studies. Conclusions: The findings indicate that bioactive-enriched CH/PVA NFs serve as effective, biocompatible, and multifunctional matrices for wound healing, hence endorsing their potential for further translational advancement in skin regeneration applications.

Royal jelly, a nutrient-rich bee product characterized by high water content and active components, is particularly susceptible to quality deterioration during storage. While temperature effects have been extensively documented, the specific role of light exposure in quality degradation remains largely unexplored. despite its relevance during production, handling, transportation, and display. This study systematically investigated the volatile organic compounds (VOCs) of royal jelly under different storage conditions using gas chromatography-ion mobility spectrometry (GC-IMS) combined with fingerprint analysis. Results from dual-column validation demonstrated that even short-term light exposure at 25 °C induced pronounced alterations in VOC profiles, triggering the accumulation of off-flavor aldehydes (e.g., hexanal, nonanal) and ketones, along with 2-furfural generated via Maillard reaction. Concurrently, characteristic fresh-aroma esters and alcohols were significantly depleted. Multivariate statistical analysis confirmed light exposure as the predominant factor driving quality deterioration, with temperature variation under dark conditions producing comparatively minor effects within the same short timeframe. This work provides the first systematic evidence establishing insights into early volatile changes in royal jelly and identifies key VOC markers that offer valuable insights for optimizing storage strategies and developing rapid quality monitoring protocols.

This study reports the development and characterization of chitosan–poly(vinyl alcohol) (CH/PVA) nanofibers (NFs), functionalized with bioactive compounds (ACs) relevant for wound healing and tissue regeneration. CH/PVA NFs loaded with L-arginine (ARG), allantoin (ALA), royal jelly (RJ) and curcumin (CUR), either as single or co-loaded systems, were prepared by electrospinning. The polymer solutions were characterized in terms of key physicochemical properties relevant to electrospinning. The CH/PVA@ACs NFs were characterized morphologically and structurally through scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Additionally, surface-related, physical, and functional properties such as wettability, swelling behavior, and in vitro release profiles were examined. The NFs were successfully produced in a uniform and continuous manner, with the fiber diameter and morphology being influenced by the type of ACs. FTIR analysis validated the characteristic functional groups linked to both the polymeric matrix and ACs. The nanofibrous systems demonstrated a high swelling capacity and a release behavior that is dependent on pH. Analyses of surface free energy and wettability revealed favorable interfacial interactions between solid and liquid, indicating compatibility with aqueous biological environments. In summary, the developed CH/PVA@ACs NFs exhibited appropriate morphological, structural, surface, and functional properties, underscoring their potential as effective materials for wound dressings.

Honey bees (Apis mellifera L.) are considered highly significant economic insects. It is a source of valuable food and medicinal products such as honey, bee pollen, royal jelly, bee brood, and beeswax, which possess excellent nutritional and pharmacological properties. Nevertheless, honey bee health and productivity were often challenged by various environmental factors. Therefore, bee colony management is of the utmost importance. In this light, bee supplements and gut microbiota are crucial to ensure that bees receive sufficient nutritional value to maintain their health and productivity. In this study, we isolate and characterize lactic acid bacteria from the hindgut of the worker bee. 16S rRNA sequencing revealed that three isolated bacteria were Apilactobacillus kunkeei (AK), Lactiplantibacillus sp. (LP), and Lactobacillus brevis (LB). Three species of lactic acid bacteria were investigated for potential probiotic properties by supplementing 50% (w/w) sucrose syrup in the form of a direct-fed microorganism (DFM). The supplement with DFM had no negative effect on average lifespan. Examination took place of the impact of probiotics on the development of the hypopharyngeal glands (HPGs) in the bee’s head at days 3, 6, and 9 post-treatments. The cage-bees fed by pollen and DFM syrup exhibited acini surface areas ranging from 0.020 to 0.023 mm². The L. brevis (LB) group exhibited enhanced HPG development, with an average acini size of 0.027 ± 0.007 mm² at day 6, while the non-treatment control had an average acini size of 0.023 ± 0.006 mm². The significant size differences were maintained throughout the 9-day period. In addition, the DFM syrup enhanced microbial protein content in the bee head, digestibility, and community complexity compared with the negative control groups. Therefore, the DFM syrup with a potential strain of probiotic may enhance overall honey bee health status. Full article

Background: The incidence of dementia, especially Alzheimer’s disease (AD), is rising, with over 55 million affected globally. Therefore, this disease, for which there is no adequate treatment, is more frequent and prevalent in women. Royal jelly, a bee secretion, is known for its health benefits and contains proteins, carbohydrates, lipids, minerals, polyphenols, enzymes, and B vitamins, as well as anti-inflammatory and antioxidant properties relevant to AD. Thus, we aimed to investigate the chemical compounds in royal jelly extract and their effect on neurobehavioral changes in an AD female model. Methods: In vitro studies were used to investigate the chemical and physicochemical properties of the royal jelly extract. In vivo studies, we divided female mice into five groups (n = 25): Control (C), Alzheimer (ALZ), ALZ standard (ALZ-STD, rivastigmine 1 mg/Kg), ALZ-D1 (royal jelly 150 mg/kg), and ALZ-D2 (royal jelly 300 mg/kg). The mice received the treatments orally at 45 days. We induced the AD model by orally administering aluminum chloride at 100 mg/kg and intraperitoneally injecting D-galactose at 120 mg/kg for 45 consecutive days, after which we subjected the animals to the radial arm maze, Morris water maze, elevated plus maze, and forced swim tests. Results: Analyses showed moderate acidity and a rich bioactive profile, with flavonoids being more prevalent. Antioxidant activity tests indicated moderate efficacy, while FTIR-ATR analysis revealed the chemical complexity of royal jelly. The royal jelly extract used in the study did not induce toxicity in vivo. Notably, royal jelly improved cognitive deficits, neurodegeneration, and reduced anxiety in AD. Conclusions: The study suggests that royal jelly extract has promising neuroprotective properties and could be a viable natural therapeutic option for AD. Full article

Bee-derived products such as apitoxin, royal jelly, propolis, bee pollen, and honey are increasingly being used as part of cosmetic products because all of them contain a large number of bioactive compounds with antioxidant, anti-inflammatory, antimicrobial, and regenerative properties, which enable them to be used for therapeutic purposes. The aim of this investigation was to assess the performance of an automated growth-based system in order to make a quantitative examination of the total aerobic viable counts in bee-derived personal care products using NF-TVC vials that contained a nutrient-based medium with dextrose as the carbon source. According to USP general chapter <1223>, pivotal validation criteria such as linearity, equivalence of results, operative range, precision, accuracy, ruggedness, limit of quantification, and limit of detection have demonstrated that the automated system can be used for a reliable total aerobic viable count. Moreover, the actual research demonstrated that polysorbates efficiently block the antimicrobiological potential of bioactive compounds, such as phenols, flavonoids, enzymes, peptides, and fatty acids, which naturally occur in apitoxin, royal jelly, propolis, bee pollen, and honey, allowing for efficient microorganism recovery from the bee-made products tested. Therefore, this AGBS could be applied efficiently within the cosmetic industry to assess the total aerobic viable count in bee-derived products such as capillary treatments, toothpaste, and anti-aging cream, affording several benefits associated with faster product release into the market.

This study aimed to identify novel angiotensin-converting enzyme (ACE)-inhibitory peptides from royal jelly proteins (RJPs) by integrating in silico digestion, virtual screening, and in vitro evaluation. Three major royal jelly proteins (MRJP1-3) were subjected to in silico digestion using 16 enzymatic systems, yielding 1411 unique peptides. Virtual screening based on predicted bioactivity, toxicity, water solubility, and ADMET profiles resulted in the selection of 27 candidate peptides. Molecular docking revealed strong binding affinities for these peptides compared with the positive control captopril, among which PYPDWSFAK and RPYPDWSF exhibited potent ACE-inhibitory activity, with IC₅₀ values of 110 ± 1.02 μmol/L and 204 ± 0.61 μmol/L, respectively. Kinetic analysis indicated that PYPDWSFAK acts as a mixed-type ACE inhibitor. Docking visualization demonstrated that PYPDWSFAK forms multiple hydrogen bonds with key residues in the ACE active pocket and directly coordinates with the catalytic Zn²⁺ ion. Cellular assays showed that PYPDWSFAK was non-cytotoxic, suppressed Ang II–induced endothelial cell migration, restored NO and ET-1 balance, and enhanced SOD and GSH-Px activities. Overall, this study enriches the repertoire of ACE-inhibitory peptides derived from royal jelly proteins. Furthermore, PYPDWSFAK is identified as a promising ACE-inhibitory peptide with potential for incorporation into natural antihypertensive ingredients or functional foods. Full article
