Multiparameter flow cytometric analysis of Mouse NK1.1/CD161 expression on C57BL/6 mouse splenocytes. C57BL/6 mouse splenocytes were stained with Phycoerythrin Rat Anti-Mouse CD49b antibody and either FITC Rabbit IgG Isotype Control (Left panel) or SDT FITC Rabbit Anti-Mouse NK1.1/CD161 antibody (Right panel) at 0.1 μg/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
CD161 is a C-type lectin-like membrane receptor expressed at high levels on NK, NKT, Th17, Mucosa Associated Invariant T cells (MAITs), non-MAIT CD8+, tissue-resident memory cells (TRMs), αβ CD4+ T cells and CD8+ T cells. CD161 levels increase when αβ T cells enter tissues. The ligand for CD161 is the lectin-like transcript 1 (LLT1). CD161/LLT1 engagement inhibits NK cell function but can inhibit or enhance αβ T cell function depending on the co-stimulatory molecules involved. The inhibitory capacity of αβ T cells can be neutralized by blocking CD161. CD161 expression on γδ T cells is associated with enhanced IFN-γ and IL-17 production and enhanced endothelial transmigration.
