Herein, we established a COPD model through long-term cigarette smoke (CS) exposure in mice with or without IL-36R deletion. Elevated IL-36 cytokines were observed in the lung and peripheral blood of CS-exposed wild-type mice. IL-36R gene deficiency attenuated CS-induced lung parenchymal destruction and airway inflammation, as evidenced by decreased secretion of inflammatory mediators, such as IL-6, IL-1β, TNF-α and MMP9, and a diminished Th1/Tc1- and Tfh-biased immune response. In addition, skeletal muscle dysfunction was alleviated in CS-exposed mice by IL-36R deletion. Further investigations indicated that CS treatment induced the expression of IL-36 cytokines and IL-36R in C2C12 myotubes and skeletal muscles, and that IL-36 cytokines could upregulate FBXO32 and TRIM63 expression by activating NF-κB p65 pathway, thereby leading to skeletal muscle atrophy in an endocrine and autocrine/paracrine manner.

Epitopes were filtered based on antigenicity, toxicity, and allergenicity to ensure that they could elicit both T and B-cell-mediated immune responses. Molecular docking simulations analyzed their interactions with Major Histocompatibility Complex (MHC) molecules. The final vaccine construct included 10 selected epitopes linked with appropriate linkers and optimized for codon usage, ensuring ideal GC content and codon adaptation index. Protein docking analyses showed strong interactions with appropriate binding energies, while molecular dynamics simulations confirmed the docked complex stability. Immune simulations revealed high antibody titers, cytokine response, and an increase in immune cells such as B Cells, Cytotoxic T Lymphocyte (CTL) cells, and Helper T Lymphocyte (HTL) cells.

It is often linked to systemic comorbidities such psoriatic arthritis, cardiovascular disease, and mental health conditions. It is characterised by erythematous plaques, itching, and scaling. Psoriasis is caused by a complex interaction of environmental factors, genetic predisposition, and dysregulated immune responses, which leads to chronic inflammation and keratinocyte hyperproliferation. This review examines the treatment potential of important protein targets linked to psoriasis. Transcriptional regulators that affect inflammatory cascades and immune cell behavior include ACKR2, NFKBIZ, and TNIP1. Proteins like PK2 and KPNA2 affect the growth and differentiation of keratinocytes, and kynurenine pathway enzymes like KYNU and IDO lead to immunological imbalance. Inflammatory mediators like CXCL10 and CYR61, as well as antimicrobial peptides like LL37 and S100A15, are significantly increased in psoriatic lesions and maintain the chronic inflammatory state. Using information from the Protein Data Bank (PDB), the review also looks at the structural biology of these proteins, providing insights into molecular interactions and drug-binding sites. The study highlights the importance of these proteins in promoting individualised psoriasis treatment by combining molecular targeting techniques with new biologic treatments. This review surveys molecular proteins implicated in psoriasis, focusing on their potential as biomarkers or therapeutic targets. While many, such as CXCL10 or S100A15, are broadly involved in inflammatory cascades, others like LL37, TNIP1, and RORγt exhibit roles more uniquely tied to psoriatic pathology and may underpin future personalized treatment approaches.</p>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"164 ","pages":"115331"},"PeriodicalIF":4.7,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144816552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its dysfunction is closely related to tumors, neurodegenerative diseases, metabolic disorders, and so on. Growing evidence indicates that KLF4 participates in multiple physiological and pathological processes through regulating autophagy, however, the underlying mechanisms are not fully understood. This article systematically reviewed the understanding of KLF4 and autophagy in recent years, critically synthesized the complex and context-dependent roles of KLF4-mediated autophagy regulation in different physiological and pathological processes, and analyzed the relevant molecular mechanisms, with an emphasis on identifying overarching regulatory patterns and functional consequences, hoping to provide theoretical basis for future in-depth research.</p>","PeriodicalId":13859,"journal":{"name":"International immunopharmacology","volume":"164 ","pages":"115350"},"PeriodicalIF":4.7,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
