ABSTRACT Primary sclerosing cholangitis (PSC) is a rare, chronic cholestatic liver disease affecting the intra- and extra-hepatic bile ducts, leading to progressive inflammation and fibrosis. Its pathogenesis is complex and involves genetic predisposition, environmental triggers, and their interaction through the gut-liver axis, mediated … Read more

ABSTRACT In systemic lupus erythematosus (SLE), chronic autoimmunity and sustained inflammation can lead to the development of neuropsychiatric lupus (NPSLE) in up to 80% of patients. Elevated interferon-alpha (IFNα) is detected in serum and cerebrospinal fluid, making it a major focus in studies … Read more

ABSTRACT Although human leukocyte antigen (HLA) class I alloimmunization is asymptomatic, it nevertheless introduces a degree of complexity in the context of transplantation or allogeneic transfusion. In practice, it is evidenced by the presence of anti-HLA-I alloantibodies in patient circulation, which can lead … Read more

Curr Opin Immunol. 2025 Jul 16;96:102611. doi: 10.1016/j.coi.2025.102611. Online ahead of print. ABSTRACT Axial spondyloarthritis (axSpA) manifests with inflammatory back pain and is diagnosed predominantly in subjects carrying the human leucocyte antigen (HLA)-B27 allele. While not diagnostic for the disease or a predictive biomarker in the general population, there is convincing data on the pathogenic … Read more

Curr Opin Immunol. 2025 Jul 16;96:102614. doi: 10.1016/j.coi.2025.102614. Online ahead of print. ABSTRACT Psoriasis is increasingly recognized as a metabolically regulated inflammatory skin disease. Aberrant glycolysis, oxidative phosphorylation, lipid metabolism, and amino acid metabolism reshape T cell, dendritic cell, macrophage, and neutrophil responses, driving chronic inflammation. Keratinocyte-derived metabolites further amplify immune dysfunction, establishing a reciprocal … Read more

Curr Opin Immunol. 2025 Jul 14;96:102609. doi: 10.1016/j.coi.2025.102609. Online ahead of print. ABSTRACT Autoimmune hepatitis (AIH) is an organ-specific autoimmune disorder mainly affecting females and characterized by seropositivity for autoantibodies, hypergammaglobulinemia, and histological evidence of interface hepatitis. Liver damage in AIH is perpetrated by multiple immune cell subsets, including B, T lymphocytes, and macrophages. Dysfunction … Read more

Curr Opin Immunol. 2025 Jul 10;96:102606. doi: 10.1016/j.coi.2025.102606. Online ahead of print. ABSTRACT Biological therapy has revolutionized the treatment landscape of complex and chronic conditions, including autoimmune diseases and cancer. However, their high costs have significantly limited patient access, particularly in low- and middle-income regions, such as Latin America and the Caribbean (LAC). As cost-effective … Read more

Curr Opin Immunol. 2025 Jul 7;95:102601. doi: 10.1016/j.coi.2025.102601. Online ahead of print. ABSTRACT Psoriatic disease encompasses psoriasis and psoriatic arthritis. It is a chronic, progressive condition and leads to irreversible joint destruction. Conventional treatments used are disease-modifying antirheumatic drugs and biologics. Janus kinase (JAK) signal transducers and activators of transcription (STAT) cell signaling protein inhibitors … Read more

Curr Opin Immunol. 2025 Jul 7;95:102602. doi: 10.1016/j.coi.2025.102602. Online ahead of print. ABSTRACT Biologic therapies have significantly improved the management of immune-mediated conditions like psoriatic disease, enhancing the quality of life of patients. However, monotherapy is often insufficient, especially in cases of relapse, concomitant psoriatic arthritis, and involvement of difficult-to-treat areas: the scalp, palmoplantar areas, … Read more
