ABSTRACT Interactions between autoimmune disorders and lymphoid malignancies have long been recognized; for instance, with prominent autoimmune manifestations in B- and T-cell lymphomas and an increased risk of lymphoma development in individuals with autoimmune diseases. More recently, several lines of evidence have shown that … Read more

ABSTRACT T cells can exchange parts of their plasma membrane along with membrane-associated proteins through trogocytosis. During trogocytosis only certain subsets of membrane-associated proteins seem to be exchanged suggesting a fine-tuned mechanism regulating the selection of what can be transferred. In this review, we … Read more

ABSTRACT An allelic variant of the autophagy gene ATG16L1 (T300A) is a genetic risk factor for Crohn’s disease. However, over 50% of the global population carries at least one copy. Yao et al. have demonstrated a heterozygote advantage, where the pathogen-protective effect of one … Read more

ABSTRACT Humanized mouse models with transgenic expression of human myelopoiesis-supporting growth factors have enhanced human myeloid cell engraftment and improved the study of human innate immune responses. Here, we discuss the remaining challenges associated with studying innate immunity in humanized NSG-SGM3 and MISTRG mice, … Read more

ABSTRACT Early antibiotic exposure disrupts the gut microbiota, impairing newborn antiviral immunity. Stevens et al. uncover that inosine, a metabolite produced by gut bacteria, restores the function of antiviral T cells by modulating gene regulation, boosting lung immune defenses against respiratory viruses.

ABSTRACT Chronic inflammation drives diseases like osteoarthritis and MASH, yet its molecular distinction from acute inflammation remains unclear. In a recent Nature study, Wang et al. revealed that chronic stress triggers WSTF degradation via nuclear autophagy, amplifying NF-κB responses. Blocking this pathway attenuates chronic … Read more

ABSTRACT CD4 T cell tolerance is essential for immune homeostasis but its mechanisms remain unclear. Although regulatory T cells (Tregs) mediate T cell-extrinsic tolerance, this review emphasizes the CD4 T cell-intrinsic pathways – anergy and exhaustion – that are triggered by suboptimal or persistent … Read more

ABSTRACT Communication between the gut microbiota and host post-translational modifications (PTMs) has been extensively characterized, and recent evidence delineates a functionally integrated gut microbiota-host PTM axis. This axis is not only essential for maintaining metabolism homeostasis but also plays diverse roles in regulating disease … Read more

ABSTRACT CD8 T cell activation and acquisition of cytolytic activity, which is essential for adaptive immunity, begins with priming in the lymph node (LN). Jobin et al. recently identified a second, delayed priming phase driven by competition with regulatory T cells for IL-2, revealing … Read more

ABSTRACT FOXP3+ regulatory T cells (Tregs) are essential for maintaining immune tolerance, and their dysfunction is a hallmark of autoimmune diseases. Recent studies have identified key transcriptional, metabolic, and environmental drivers of Treg instability and loss of function. Understanding these mechanisms opens new avenues … Read more
