Specificity
This antibody recognises human MIP-1 beta, otherwise known as CCL4, a 69 amino acid member of the CC chemokine family, shown to signal through the chemokine receptors CCR1, CCR2 and CCR5.MIP-1 beta is involved in host defence against invading pathogens, acting as a regulator of activation and trafficking of inflammatory cells, such as monocytes, B cells, NK cells, neutrophils, dendritic cells and CD4+ lymphocytes.The secretion of MIP-1 beta by CD8+ lymphocytes has been shown to act as a major HIV-suppressive factor (HIV-SF) through binding to CCR5, identified as a coreceptor for HIV-1 target cell entry.
