Regulation of NK cell activity by 2B4, NTB-A and CRACC.
نویسندگان
چکیده
2B4, NTB-A and CRACC are members of the recently defined family of SLAM-related receptors. Here we review the role of these receptors for the regulation of Natural Killer cell function and describe the current knowledge about the signal transduction of these receptors. Finally, we critically analyze some controversial data about the function of 2B4 in mouse and man.

Activation of natural killer cells can be mediated by different receptors. Stimulation of the receptors 2B4, NTB-A and CRACC, members of the SLAM-related receptor family, induces cytotoxicity and cytokine production. The surface expression of 2B4 and other activating natural killer cell receptors is down-modulated after receptor engagement, which results in a weaker response to consecutive stim...
متن کاملThe cytotoxicity receptor CRACC (CS-1) recruits EAT-2 and activates the PI3K and phospholipase Cgamma signaling pathways in human NK cells.
The CD2-like receptor-activating cytotoxic cell (CRACC) is a cell surface receptor of the CD2 family that triggers NK cell-mediated cytotoxicity through an undefined signaling pathway. CRACC contains cytoplasmic tyrosine-based motifs, immunoreceptor tyrosine-based switch motifs, which resemble those found in the NK cell receptor 2B4. In 2B4, these motifs recruit the adaptor signaling lymphocyti...

In humans, natural killer (NK) cell function is regulated by a series of receptors and coreceptors with either triggering or inhibitory activity. Here we describe a novel 60-kD glycoprotein, termed NTB-A, that is expressed by all human NK, T, and B lymphocytes. Monoclonal antibody (mAb)-mediated cross-linking of NTB-A results in the induction of NK-mediated cytotoxicity. Similar to 2B4 (CD244) ...
متن کاملNK cell cytotoxicity mediated by 2B4 and NTB-A is dependent on SAP acting downstream of receptor phosphorylation
2B4 (CD244) and NK-T-B-antigen (NTB-A, CD352) are activating receptors on human natural killer (NK) cells and belong to the family of signaling lymphocyte activation molecule (SLAM)-related receptors (SRR). Engagement of these receptors leads to phosphorylation of their cytoplasmic tails and recruitment of the adapter proteins SLAM-associated protein (SAP) and Ewing's sarcoma-activated transcri...
متن کاملThe human 2B4 and NTB-A receptors bind the influenza viral hemagglutinin and co-stimulate NK cell cytotoxicity
Natural Killer (NK) cells are critical in the defense against viruses in general and against influenza in particular. We previously demonstrated that the activating NK cell receptor NKp46 is involved in the killing of influenza-virus infected cells through its interaction with viral hemagglutinin (HA). Furthermore, the recognition by NKp46 and consequent elimination of influenza infected cells ...
