Article Abstract

Invariant V alpha 14 bearing natural killer T cells (iNKT) cells constitute a subset of lymphocytes that recognize lipid-based ligands presented by the non-classical MHC class I-like molecule CD1d and responds with rapid cytokine production. Despite their multiple implications in regulating immune responses, pertaining to cancer and auto-immunity, the molecular requirements for their development in the thymus are poorly understood. Here we discuss recent evidence that c-Myc mediates an intrathymic proliferation wave immediately following agonist selection of iNKT cells that is vital for the generation of mature iNKT cells in vivo. We review aspects of early iNKT ontogeny in light of our findings and speculate about possible mechanistic links controlling c-Myc activity in newly selected cells.

Intraepithelial type 1 innate lymphoid cells (ieILC1s) are tissue-resident lymphocytes in the microenvironment of head and neck squamous cell carcinoma. Here, we evaluate how these cells influence T-cell trafficking to tumors. We generated cytotoxic ieILC1-like cells from natural killer (NK) cells in vitro.

Sepsis, a leading cause of mortality in intensive care units worldwide, lacks effective treatments for advanced-stage sepsis. Therefore, understanding the underlying mechanisms of this disease is crucial. This study reveals that invariant natural killer T (iNKT) cells have an opposing role in the progression of sepsis by suppressing regulatory T (Treg) cell differentiation and function.

Natural killer (NK) cell activity is influenced by cytokines and microenvironment factors, resulting in remarkably diverse functions, by contributing to inflammatory responses or serving as rheostats of adaptive immunity. Using single cell RNA sequencing (scRNA-seq), we identified a CD56NK cell population associated with hematopoietic stem cell transplant recipients protected from acute graft-versus-host disease (GVHD). We further define a role for the combination of interleukin-2 (IL-2) and transforming growth factor β1 (TGF-β1) in promoting a regulatory phenotype in NK cells.

Insights into the complexities of Citrullination: From immune regulation to autoimmune disease.

Autoimmun Rev

December 2024

Department of Clinical Immunology, PLA Specialized Research Institute of Rheumatology & Immunology, Xijing Hospital and National Translational Science Center for Molecular Medicine, Fourth Military Medical University, Shaanxi, China. Electronic address:

Citrullination, a post-translational modification that changes arginine to citrulline in proteins, is vital for immune response modulation and cell signaling. Catalyzed by peptidyl arginine deiminases (PADs), citrullination is linked to various diseases, particularly autoimmune disorders like rheumatoid arthritis (RA). Citrullinated proteins can trigger the production of anti-citrullinated protein antibodies (ACPAs), included in RA classification criteria.
