Macrophage inflammatory proteins (MIP) belong to CC-motif chemokines and the two isoforms called MIP-1α (CCL3) and MIP-1β (CCL4) are induced by exposure of macrophages to endotoxins and the elevated expression of these inflammatory proteins was observed in primary monocytes obtained from T2D patients [6]. Here, CCL4 is linked to type 2 diabetes mellitus.
