Synthesis pass · prose summary of the discoveries below

CD244 (2B4) is a SLAM-family immunoreceptor that binds CD48 and functions as a context-dependent activating or inhibitory receptor across NK cells, T cells, eosinophils, mast cells, dendritic cells, and macrophages, governing cytotoxicity, cytokine production, phagocytosis, and immune self-tolerance. When the adaptor SAP is present, CD244 engagement recruits FynT via cytoplasmic TxYxxV/I motifs, triggering phosphorylation of Vav-1, SHIP-1/c-Cbl, and Ras/MAPK (ERK, p38) and PLC-γ1 cascades that drive NK cell killing and IFN-γ secretion; when SAP is absent—as in X-linked lymphoproliferative disease (XLP1)—or when CD244 expression is high, the receptor instead recruits SH2-containing phosphatases, competes with CD2 for CD48 binding, and blocks actin-dependent lipid raft recruitment, converting it to an inhibitory receptor (PMID:15169881, PMID:18523281, PMID:12515815, PMID:19586919, PMID:28386908). Beyond classical lymphocyte regulation, CD244 on macrophages acts as a "don't eat me" signal that suppresses LRP1/mTOR/Syk-mediated phagocytosis independently of CD47, and inhibits anti-tumorigenic macrophage differentiation by suppressing autophagy pathways (PMID:35061505, PMID:38424542). CD244 also epigenetically represses IFN-γ and TNF-α in CD8+ T cells during tuberculosis infection by inducing lncRNA-CD244, which recruits EZH2 to install H3K27me3 at cytokine promoters (PMID:26150504).
