Curr Opin Immunol. 2025 Aug 5;96:102634. doi: 10.1016/j.coi.2025.102634. Online ahead of print. ABSTRACT Alloimmunization to blood group antigens is the result of a humoral immune response initiated by exposure to foreign antigens absent from the recipient’s red blood cells (RBCs). Interestingly, not all individuals who receive mismatched RBC transfusions develop alloantibodies. Increasing evidence points to … Read more
Curr Opin Immunol. 2025 Aug 5;96:102633. doi: 10.1016/j.coi.2025.102633. Online ahead of print. ABSTRACT The complement system, a central component of innate immunity, is implicated in tumor biology, influencing processes such as tumor progression, immune evasion, and response to therapy. Numerous studies have identified alterations in complement effectors, activation products, regulatory proteins, and receptors in patients … Read more
Curr Opin Immunol. 2025 Aug 1;96:102630. doi: 10.1016/j.coi.2025.102630. Online ahead of print. ABSTRACT Inflammatory memory refers to the ability of an organism to mount a stronger or faster response upon re-exposure to similar inflammatory stimuli. This heightened sensitivity was once thought to be a unique characteristic of immune cells. However, recent studies have challenged this … Read more
Curr Opin Immunol. 2025 Jul 28;96:102617. doi: 10.1016/j.coi.2025.102617. Online ahead of print. ABSTRACT Blood transfusion is integral to modern medicine but carries significant immunological risks. This review outlines key immune-mediated complications, including acute hemolytic transfusion reactions from ABO incompatibility, and febrile nonhemolytic reactions caused by cytokines or antileukocyte antibodies. Other reactions include allergic responses, anaphylaxis … Read more
Curr Opin Immunol. 2025 Jul 28;96:102618. doi: 10.1016/j.coi.2025.102618. Online ahead of print. ABSTRACT As with all autoimmune diseases, antineutrophil cytoplasmic autoantibody (ANCA) vasculitis cannot be cured by a singular approach. This complexity arises because autoimmune conditions typically result from multiple hits to the immune system – including genetic predisposition, environmental exposures, infections, and perturbations in … Read more

ABSTRACT Age-related macular degeneration (AMD) is a leading cause of irreversible central vision loss in elderly populations across developed countries. Complement system dysregulation has been implicated in AMD onset and evolution. Complement inhibition therapies have been authorized in the USA as the primary … Read more
Curr Opin Immunol. 2025 Jul 18;96:102612. doi: 10.1016/j.coi.2025.102612. Online ahead of print. ABSTRACT In order to stay circulating in the human population over many years, viruses need to adapt to the environment, mainly to the host’s immune response, allowing for reinfection despite preexisting immunity. These different viral strategies are clearly important for guiding vaccine design. … Read more
Curr Opin Immunol. 2025 Jul 18;96:102615. doi: 10.1016/j.coi.2025.102615. Online ahead of print. ABSTRACT Langerhans cells (LCs), the professional antigen-presenting cells in the epidermis, serve as the first line of defense in the skin’s immune system. With advancements in detection technologies and the development of diverse animal models, LCs have been shown to exhibit heterogeneous origins, … Read more
Curr Opin Immunol. 2025 Jul 17;96:102613. doi: 10.1016/j.coi.2025.102613. Online ahead of print. 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
Curr Opin Immunol. 2025 Jul 18;96:102608. doi: 10.1016/j.coi.2025.102608. Online ahead of print. 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
