Abstract The high abundance of Corynebacterium simulans in psoriasis skin suggests a contribution to the aetiology. This hypothesis was tested an exploratory study, where western blot (WB) analyses with extracts heat‐treated C. and serum‐derived IgG exhibited single 16 kDa‐WB‐band. Proteomic revealed ribosomal proteins as candidate s. ‐antigens. A peptidomic analysis unexpectedly showed that already contained 31 immunopeptides Corynebacteria ssp., suggesting presence natural bispecific antibodies (BsAbs). Moreover, gave 372 DECOY‐peptides similarity virus‐ phage proteins, including diphtheriae , diphtheria toxin. Strikingly, for human peptides 64 epitopes major autoantigens such spacer region filaggrin, hornerin repeats others. Most identified represent potential cationic intrinsically disordered antimicrobial (CIDAMPs), which are generated within epidermis. These may form complexes bacterial protein regions, representing chimeric antigens containing discontinuous epitopes. In addition, among 128 low‐abundance immunopeptides, 48 putatively psoriasis‐relevant epitope PGE2‐, vitamin D3‐ IL‐10‐receptors. Further, 47 originated from tumour antigens, endogenous retrovirus HERV‐K. I propose persistent infection toxigenic initiates psoriasis, is exacerbated autoimmune disease by CIDAMPs autoantigens. discovery BsAbs allows identification antigen microbes, viruses, tumour‐antigens, help develop epitope‐specific peptide‐vaccines therapeutic approaches antigen‐specific regulatory T cells improve immune tolerance disease‐specific‐manner.

Abstract Psoriasis is a common, chronic, and inflammatory skin disease with high burden on individuals, health systems, society worldwide. With the immunological pathologies pathogenesis of psoriasis becoming gradually revealed, therapeutic approaches for this have gained revolutionary progress. Nevertheless, mechanisms less common forms remain elusive. Furthermore, severe adverse effects recurrence upon treatment cessation should be noted addressed during treatment, which, however, has been rarely explored integration preliminary findings. Therefore, it crucial to comprehensive understanding behind pathogenesis, which might offer new insights research lead more substantive progress in expand clinical options treatment. In review, we looked briefly introduce epidemiology, subtypes, pathophysiology, comorbidities systematically discuss signaling pathways involving extracellular cytokines intracellular transmission, as well cross-talk between them. discussion, also paid attention potential metabolic epigenetic molecular mechanistic cascades related its comorbidities. This review outlined current psoriasis, especially targeted therapies novel strategies, mechanism recurrence.

The term "immune-mediated inflammatory diseases (IMIDs)" refers to several pathologies of multifactorial etiology and involving either simultaneously or sequentially more organs. IMIDs share some common pathogenic mechanisms, which account for similarities in the clinical course impact that these may have on other organs systems body. However, there are differences IMID-associated pathological process, including synthesis function multiple cytokines, supposed perpetuate tissue-damaging inflammation. This justifies different indications responsiveness corticosteroids, immunosuppressors, small molecules, biologics.

Psoriasis (PSO) is a chronic autoimmune skin condition characterized by the rapid and excessive growth of cells, which leads to formation thick, red, scaly patches on surface skin. These can be itchy painful, they may cause discomfort for patients affected this condition. Therapies psoriasis aim alleviate symptoms, reduce inflammation, slow down cell growth. Conventional topical treatment options are non-specific, have low efficacy associated with adverse effects, why researchers investigating different delivery mechanisms. A novel approach drug using nanoparticles (NPs) shows promise in reducing toxicity improving therapeutic efficacy. The unique properties NPs, such as their small size large area, make them attractive targeted delivery, enhanced stability, controlled release. In context PSO, NPs designed deliver active ingredients anti-inflammatory effect, immunosuppressants, or other compounds directly areas. formulations offer improved access epidermis facilitate better absorption, thus enhancing conventional anti-psoriatic drugs. increase surface-to-volume ratio, resulting penetration through skin, including intracellular, intercellular, trans-appendage routes. present review aims discuss latest approaches therapy PSO NPs.
