J Immunol. 2026 Mar 25;215(S3):vkaf322. doi: 10.1093/jimmun/vkaf322. ABSTRACT The choroid plexus (ChP) is increasingly recognized as a dynamic neuroimmune interface that integrates peripheral and central signals to regulate cerebrospinal fluid (CSF) homeostasis, leukocyte trafficking, and inflammatory tone within the central nervous system (CNS). Recent studies reveal that beyond their classic roles in CSF production and … Read more

J Immunol. 2026 Mar 17;215(3):vkag033. doi: 10.1093/jimmun/vkag033. ABSTRACT Interleukin 1-beta (IL-1β) is an inflammatory cytokine produced by myeloid cells in response to infection or sterile tissue damage. Secretion of bioactive IL-1β from macrophages (Mφ) or dendritic cells (DC) downstream of activated NLRP3/caspase-1 inflammasomes is the best characterized model; this is mediated by caspase-1 cleavage of … Read more

J Immunol. 2026 Mar 17;215(3):vkag009. doi: 10.1093/jimmun/vkag009. ABSTRACT Echoviruses commonly infect humans and can cause severe outcomes, including meningitis and liver failure, especially in neonates and immunocompromised individuals. Although recent progress has been made in understanding acute pathogenesis and innate immunity to echoviruses, adaptive immune responses remain poorly defined, in part due to the lack … Read more

J Immunol. 2026 Mar 17;215(3):vkag001. doi: 10.1093/jimmun/vkag001. ABSTRACT The traditional view of the immune system distinguishes between the innate immune system, which serves as the host’s first line of defense against pathogens, and the adaptive immune system, which evolved to manage more complex or recurrent infections. However, the discovery of evolutionarily conserved mechanisms in innate … Read more

J Immunol. 2026 Mar 19:vkag022. doi: 10.1093/jimmun/vkag022. Online ahead of print. ABSTRACT The Syrian hamster (Mesocricetus auratus) is an important model for human infectious diseases, particularly those that infect the respiratory tract, due to having similar disease progression and immune responses as humans. However, immune repertoire studies are extremely limited due to incomplete genomic characterization … Read more

J Immunol. 2026 Mar 17;215(3):vkag013. doi: 10.1093/jimmun/vkag013. ABSTRACT Immunotherapies have greatly improved outcomes for patients with renal cell carcinoma (RCC), yet response rates remain suboptimal and the factors promoting therapy resistance versus sensitivity are incompletely understood. Currently, no preclinical model of orthotopic renal cancer exists that permits evaluation of tumor antigen-specific (TAS) CD8+ tumor-infiltrating lymphocytes … Read more

J Immunol. 2026 Mar 17;215(3):vkag026. doi: 10.1093/jimmun/vkag026. ABSTRACT Tumor-associated macrophages are an abundant, tumor-infiltrating cell population that supports the evasion of tumor cells from antitumoral immune cell detection by generating an immunosuppressive tumor-immune microenvironment (TIME). The immunosuppressive function of macrophages is dictated by the cytokine environment. IL-9 is a pleiotropic cytokine that can be a … Read more

J Immunol. 2026 Mar 17;215(3):vkag029. doi: 10.1093/jimmun/vkag029. ABSTRACT Autophagy serves as a crucial defense mechanism against Mycobacterium tuberculosis (Mtb) survival within infected macrophages. Transcription factor EB (TFEB) and upstream stimulatory factor 2 (USF2) belong to the bHLH-Zip family and regulate the transcription of autophagy-related genes, thereby modulating host-pathogen interactions. However, the mechanisms by which Mtb … Read more

J Immunol. 2026 Mar 17;215(3):vkag020. doi: 10.1093/jimmun/vkag020. ABSTRACT Asthma is a chronic airway disease driven by type 2 immune responses, a core mechanism shared across allergic conditions. Cathepsins (CTSs), lysosomal proteases that regulate immune processes such as autophagy, antigen presentation, and cytokine modulation, have been implicated in allergy, but whether specific CTSs-particularly cathepsin B (CTSB)-causally … Read more
