BACKGROUND Chemokines (chemotactic cytokines) are small heparin-binding proteins, which constitute a large family of peptides (60-100 amino acids) structurally related to cytokines whose main function is to regulate cell trafficking. They are subdivided into four families based on the number and spacing of the conserved cysteine residues in the N-terminus of the protein: CXC, CC, CX3C, and C, in agreement with the systematic nomenclature. Chemokines play a major role in selectively recruiting monocytes, neutrophils and lymphocytes as well as inducing chemotaxis through the activation of G-protein-coupled receptors (GPCR).1
MIP-1alpha is a member of the C-C chemokine family. Similar to MCP-1, MIP-1alpha can mediate the recruitment of monocytes in several inflammatory diseases. MIP-1alpha also leads to a local accumulation of neutrophils when it is subcutaneously injected. MIP-1alpha has been shown to play a role in several inflammatory diseases. For example, bleomycin-induced pulmonary fibrosis is decreased when MIP-1alpha is inhibited, and influenza-induced pneumonitis is dependent on the presence of MIP-1alpha. These many studies support the notion that both MCP-1 and MIP-1alpha are key molecules in macrophage trafficking into inflammatory foci.2 In addition, it was shown that MIP-1alpha attract CD8+ T cells, B lymphocytes, and NK cells.3 It can stimulate basophil to release histamine and induce ICAM-1 expression, mast degranulation, and production of TNF-alpha, IL-1, and IL-6.2
MIP-1alpha binds to CCR1, CCR4 and CCR5 chemokine receptors. It is one of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant MIP-1alpha induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV).4
