Flow cytometric analysis of Mouse splenocytes cells labelling NK1.1/CD161 antibody at 1/50 dilution (1 μg) (Right) compared with a Rabbit monoclonal IgG isotype control (Left). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody. Cells were stained with rabbit IgG or NK1.1. Then stained with CD49b - PE. Gated on viable cells.

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.
