Curr Opin Immunol. 2026 May 15;101:102788. doi: 10.1016/j.coi.2026.102788. Online ahead of print. ABSTRACT The spleen is a central immune organ that surveys blood-borne pathogens and coordinates systemic immune responses. Within this organ, conventional dendritic cell (cDC) subsets occupy blood-exposed niches that enable efficient antigen capture and rapid initiation of T cell activation. While splenic cDC1s … Read more
Curr Opin Immunol. 2026 May 14;100:102786. doi: 10.1016/j.coi.2026.102786. Online ahead of print. ABSTRACT Primary biliary cholangitis (PBC) is a chronic immune-mediated liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis, fibrosis, and eventual cirrhosis. Despite advances in understanding disease pathogenesis, treatment pathways are focused on maintenance rather than cure. Moreover, … Read more
Curr Opin Immunol. 2026 May 13;100:102787. doi: 10.1016/j.coi.2026.102787. Online ahead of print. ABSTRACT Efficacious immune responses require the coordinated encounter of rare antigen-specific adaptive lymphocytes with their cognate innate antigen-presenting cells (APCs) in space and time. This spatiotemporal problem of immunity is solved by secondary lymphoid organs, such as lymph nodes (LNs), which coordinate adaptive … Read more
Curr Opin Immunol. 2026 May 4;100:102784. doi: 10.1016/j.coi.2026.102784. Online ahead of print. ABSTRACT The lupus anticoagulant (LA) phenomenon represents a paradoxical prothrombotic state characterised by inhibition of phospholipid-dependent coagulation assays in vitro, despite a strong association with thrombosis and pregnancy morbidity in vivo. LA is a central laboratory criterion for the diagnosis and risk stratification … Read more
Curr Opin Immunol. 2026 Apr 30;100:102782. doi: 10.1016/j.coi.2026.102782. Online ahead of print. ABSTRACT Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterized by fluctuating multisystem involvement, relapsing-remitting activity, and substantial risk of irreversible organ damage. Standardized disease activity indices have facilitated clinical trials and research, yet integration into clinical practice has not occurred for … Read more
Curr Opin Immunol. 2026 Apr 29;100:102783. doi: 10.1016/j.coi.2026.102783. Online ahead of print. ABSTRACT Allogeneic hematopoietic cell transplantation (alloHCT) is curative for many patients with high-risk, hematologic malignancies. AlloHCT depends on a graft versus malignancy (GVM) phenomenon, whereby donor-derived immune cells recognize and eradicate malignant host cells. Successful GVM correlates with the risk of alloreactivity against … Read more

ABSTRACT Viral encephalitis (VE) is a universal menace accounting for severe morbidity and mortality among the affected individuals. VE is the cerebral inflammation triggered by viral infections. In the central nervous system, microglia are the frontline responders that provide defense against invading pathogens, … Read more
Curr Opin Immunol. 2026 Apr 22;100:102780. doi: 10.1016/j.coi.2026.102780. Online ahead of print. ABSTRACT Ca²⁺ release-activated Ca²⁺ (CRAC) channels facilitate store-operated Ca²⁺ entry in both immune and nonimmune cells. They are crucial for the function of many immune cell types and strongly associated with the pathophysiology of immune-related disorders. Inherited null mutations in the genes encoding … Read more
Curr Opin Immunol. 2026 Apr 20;100:102770. doi: 10.1016/j.coi.2026.102770. Online ahead of print. ABSTRACT Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by thrombosis, microvascular disease, pregnancy morbidity, or non-thrombotic manifestations in patients with antiphospholipid antibodies. The mechanistic differentiation of these clinical phenotypes has diagnostic and therapeutic implications. Across APS phenotypes, a shared set of … Read more
Curr Opin Immunol. 2026 Apr 16;100:102777. doi: 10.1016/j.coi.2026.102777. Online ahead of print. ABSTRACT Immunosenescence is a multidimensional remodeling of immunity, characterized by inflammaging, cellular senescence, T-cell exhaustion, and thymic involution, that raises infection and disease risk with age. Emerging evidence, notably from centenarians, shows immune aging follows divergent trajectories: rather than a uniform decline, extreme … Read more
