| 描述 |
Leukocyte immunoglobulin-like receptor subfamily B member 3 (LILRB3) is a member of Leukocyte Immunoglobulin-Like Receptors family, and there are 11 receptors that have two to four extracellular Ig-like domains, and are categorized as inhibitory or activating. The inhibitory receptors (LILRB1 to B5) possess long cytoplasmic tails containing ITIMs, whilst the activating receptors (LILRA1 to A6, excluding A3) possess short cytoplasmic tails and couple with ITAM-bearing FcεRIγ.ILRB3 is ITIM-bearing, whilst LILRA6 associates with FcRγ. LILRB3 is released from the surface through an uncharacterized mechanism upon degranulation, This raises the possibility that LILRB3 modulates the maturation and/or early activation of neutrophils. |
