The<unk> s <unk>  are two 7-transmembrane proteins in the G-protein coupled-receptor family:<unk>  A <unk> A) and<unk>  B <unk> B). These receptors are generally found on human neutrophils, a type of white blood cell of the myeloid lineage, with approximately 65,000 receptors per neutrophil. Both receptors have a size of 60kDa, are glycosylated (contains covalent attachments and modifications) and G-protein linked, and can cause an increase in intracellular Ca2+ levels. Binding of<unk> <unk>  leads to activation of the cell (commonly a neutrophil), allowing it to recruit more white blood cells to the site of<unk> <unk>  release and to produce enzymes that would assist in the destruction of foreign material at the site of infection
