Natural Killer T (NKT) cells are a unique subset of T lymphocytes that function at the interface of the innate and adaptive immune systems. They express a semi-invariant T-cell receptor (TCR) and recognize lipid antigens presented by the CD1d molecule. They respond rapidly to stimuli and produce a broad array of cytokines, influencing immune responses against infections, tumors, and autoimmune diseases [1].

This dual functionality allows NKT cells to enhance the body’s ability to respond to diverse challenges [1,2,3].

Prof. Dr. Hermann Wagner (Technical University of Munich) has explored NKT cell roles in immune responses, and their interactions with other immune cells and potential therapeutic applications [4]. 
Prof. Dr. Andrea Ablasser (formerly University of Bonn) has provided insights into innate immune recognition mechanisms that inform studies on NKT cell activation [4]. 
Prof. Dr. Philip Rosenstiel (Kiel University) investigates molecular pathways in chronic inflammatory diseases, shedding light on NKT cell contributions to such conditions [4].
