Both MIP-1α and MIP-1β (macrophage inflammatory proteins-1α and β) are structurally and functionally related CC chemokines. They are secreted by activated human monocytes and peripheral blood lymphocytes. The gene encoding this protein is localized on human chromosome 17q12.
Immunogen
CCL4 (NP_002975.1, 1 a.a. ~ 92 a.a) full-length human protein.
MIP-1α and MIP-1β (macrophage inflammatory proteins-1α and β) participate in the host response to invading bacterial, viral, parasite and fungal pathogens by regulating the trafficking and activation state of selected subgroups of inflammatory cells e.g. macrophages, lymphocytes and natural killer (NK) cells. While both MIP-1α and MIP-1β exert similar effects on monocytes their effect on lymphocytes differ; with MIP-1α selectively attracting CD8+ lymphocytes and MIP-1β (also known as C-C motif chemokine ligand 4) selectively attracting CD4+ lymphocytes. Additionally, MIP-1α and MIP-1β have also been shown to be potent chemoattractants for B cells, eosinophils and dendritic cells.
