anti-mouse CCL-4 monoclonal antibody Anti-Mouse 50 µg,Reliatech,103-M334

CCL4, also known as macrophage inflammatory protein 1 beta (MIP1β), is a 12 kDa β chemokine that is secreted at sites of inflammation by activated leukocytes, lymphocytes, vascular endothelial cells, and pulmonary smooth muscle cells (1, 2). CCL4 attracts a variety of immune cells to sites of microbial infection as well as to other pathologic inflammation such as allergic asthma and ischemic myocardium. A CCL4 deficiency in mice promotes the development of autoantibodies, possibly as a result of compromised regulatory T cell recruitment. CCL4 is secreted from activated monocytes as a heterodimer with CCL3/MIP1α. The first two N-terminal amino acids can be cleaved from human CCL4 by CD26/DPPIV. Both the full length and truncated forms exert biological activity through CCR5, and the truncated form additionally interacts with CCR1 and CCR2. In humans, the ability of CCL4 to bind CCR5 inhibits the cellular entry of Mtropic HIV1 which utilizes CCR5 as a coreceptor. Both forms of CCL4 block HIV1 infection of T cells by inducing the downregulation of CCR5. Mature mouse CCL4 shares 77% and 86% amino acid sequence identity with human and rat CCL4, respectively.
