iNKT Cells Exacerbate Sepsis-Associated Acute Lung Injury through IFN-γ-Mediated Promotion of Macrophage Apoptosis

GSE308524 Mus musculus Expression profiling by high throughput sequencing 6 samples Submitted 2025/09/23 Platform GPL34290
Summary
iNKT cells are a unique subset of T lymphocytes that play important and distinct roles in sepsis due to their specialized characteristics. Unlike conventional T cells, which are restricted by polymorphic major histocompatibility complex (MHC) molecules and recognize peptide antigens, iNKT cells are restricted by the non-polymorphic CD1d molecule and respond to lipid antigens. Upon activation, they rapidly produce large quantities of cytokines such as IFN-γ and IL-4. While the immunoregulatory function of iNKT cells in sepsis has been well established, their dual capacity to exert both pro-inflammatory and anti-inflammatory effects remains incompletely understood. In particular, their specific role during the early stages of sepsis remains elusive. This study aims to elucidate the mechanism by which iNKT cells contribute to immune dysregulation in sepsis through the iNKT-macrophage axis.
