CD69, also known as CLEC2C, is a type 2 transmembrane glycoprotein in the C-type lectin family. It plays roles in immune cell trafficking, inflammation, T cell memory, and humoral immune responses (1). Mature mouse CD69 consists of a 40 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 138 aa extracellular domain with one C-type lectin domain (CTL) (3). Within the ECD, mouse CD69 shares 57% and 76% aa sequence identity with human and rat CD69, respectively. CD69 is expressed on the cell surface as an approximately 60 kDa disulfide-linked homodimer (3-5). It is found on CD4⁺ T cells, CD8⁺ T cells, NK cells, NKT cells, gamma delta cells dendritic cells (DC) and is up-regulated on activated T cells and DC (6-8). Ligation of CD69 on DC induces IL-2 production, leading to T cell proliferation (6). CD69 is important for the homing of CD4⁺ T cells and plasmablasts to the bone marrow but inhibits the migration of dermal DC to draining lymph nodes (7, 9). It supports the expression of multiple chemokines and chemokine receptors but suppresses the expression of others (10, 11). It associates with and negatively regulates S1P1 expression on DC and CD4⁺ T cells, resulting in a decreased chemotactic response to S1P (7, 12, 13). S1P1 similarly inhibits the cell surface expression of CD69 (12). The direct interaction of CD69 with Galectin-1 contributes to the ability of CD69 to limit Th17 mediated inflamamtion while supporting the differentiation of regulatory T cells (8, 10, 13-16). In various disease models, CD69 has been shown to have both enhancing and inhibitory effects on Th17 and Th2 cell mediated inflammation (8, 10, 11, 13, 16, 17).
