J Immunol. 2026 Mar 17;215(3):vkag014. doi: 10.1093/jimmun/vkag014. ABSTRACT The fetomaternal interface (FMi), comprising fetal chorionic trophoblast cells (CTCs) and maternal decidual stromal cells (DECs), plays a critical role in providing immune tolerance during pregnancy. Intrauterine inflammation is major trigger of adverse outcomes such as preterm birth, yet the cell-specific inflammatory responses at the FMi -; … Read more

J Immunol. 2026 Mar 17;215(3):vkag025. doi: 10.1093/jimmun/vkag025. ABSTRACT Antibodies are secreted by specialized antibody-secreting cells, also known as plasma cells (PCs), which differentiate from antigen-activated B cells. Antibodies are critical for protection against many types of infection and are correlates of vaccine efficacy. Iron metabolism is important for antibody responses, and heme (the major source … Read more

J Immunol. 2026 Mar 17;215(3):vkag034. doi: 10.1093/jimmun/vkag034. ABSTRACT N6-methyladenosine (m6A) represents a reversible and ubiquitous posttranscriptional modification of mRNA. It plays a crucial role in immune cell development and is implicated in a range of pathological conditions. Nevertheless, the precise role of m6A in LPS-induced macrophage inflammatory responses remains elusive. In the present study, we … Read more

J Immunol. 2026 Mar 17;215(3):vkag017. doi: 10.1093/jimmun/vkag017. ABSTRACT Chemokines play a crucial role in the lung’s immune responses to infections and diseases. The role of CXC ligand 13 (CXCL13), a chemokine produced homeostatically by various lung cell types, in protecting against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and disease remains controversial. Some studies … Read more

J Immunol. 2026 Mar 17;215(3):vkag015. doi: 10.1093/jimmun/vkag015. ABSTRACT Histone deacetylase HDAC7 is required for early B cell development and governs the acquisition of B cell progenitors gene identity. Its role in mature B cell biology and associated malignancies is unknown. Here, by using a conditional mouse model for specific deletion in activated B cells, we … Read more

J Immunol. 2026 Mar 17;215(3):vkag018. doi: 10.1093/jimmun/vkag018. ABSTRACT Acute hepatopancreatic necrosis disease (AHPND) is one of the most severe threats to global shrimp aquaculture. Recent studies report a significant reduction in hepatopancreas hemocyanin levels in Penaeus vannamei (PvHMC) by AHPND. To investigate the functional implications, we performed liquid chromatography-tandem mass spectrometry-based metabolomics and found that … Read more

J Immunol. 2026 Mar 17;215(3):vkaf361. doi: 10.1093/jimmun/vkaf361. ABSTRACT Infants are significantly more susceptible to respiratory infection, often resulting in increased morbidity and hospitalization, and occasionally death. This susceptibility is partially explained by the developing nature of the thymus in human infants at-and for several months after-birth. However, the contribution of T cells produced in this … Read more

J Immunol. 2026 Feb 9;215(2):vkaf304. doi: 10.1093/jimmun/vkaf304. ABSTRACT Viral infections remain a challenge to aquaculture, resulting in severe economic losses and threatening fish health worldwide. As a key immunomodulatory and antiviral factor, interferon (IFN) plays a crucial role in regulating immune responses. We constructed a high-level expression strain of recombinant interferon (Rec-IFN) using Synechococcus sp. … Read more

J Immunol. 2026 Feb 9;215(2):vkaf366. doi: 10.1093/jimmun/vkaf366. ABSTRACT Epstein-Barr virus (EBV) is a human γ-herpesvirus that establishes latency and lifelong infection in B cells. Failure to control latent EBV infection can result in a variety of malignancies, including lymphoproliferative diseases. Studies have implicated natural killer (NK) cells as critical in the host defense against lytic … Read more

J Immunol. 2026 Feb 9;215(2):vkaf368. doi: 10.1093/jimmun/vkaf368. ABSTRACT Negative T-cell regulation through programmed cell death 1 (PD-1)-programmed death ligand 1 (PD-L1) ligation is well described during viral infection; however, our understanding of the contribution of PD-L1-intrinsic signaling to antiviral immunity is limited. Herein, we show that mutation of the PD-L1 intracellular domain results in a … Read more
