描述:
CCL3, also known as macrophage inflammatory protein 1 alpha (MIP1α)
and LD78, is a member of the β or CC subfamily of chemokines and is closely related to
CCL4/MIP1β. Chemokines comprise a large family of small secreted proteins that are
involved in immune and inflammatory responses. CCL3 expression can be
induced in a variety of hematopoietic cells, fibroblasts, smooth muscle cells,
and epithelial cells. Mature cotton rat CCL3 shares 70%, 82%, and 88% amino acid
sequence identity with human, mouse, and rat CCL3, respectively. CCL3 is an
approximately 8 kDa chemokine that forms complexes with sulfated proteoglycans.
In a reversible process, CCL3 associates into noncovalentlylinked dimers which then
form tetramers and high molecular weight polymers. These complexes
of CCL3 are protected from proteolytic digestion by insulin degrading enzyme (IDE)
which can cleave the monomeric chemokine. CCL3 exerts its biological
functions through interactions with CCR1, CCR3, and CCR5. It is cleared from the
extracellular space by internalization via the decoy chemokine receptor D6.
CCL3 promotes the chemoattraction, adhesion to activated vascular endothelium,
and cellular activation of many hematopoietic cell types including activated T cells,
NK cells, neutrophils, monocytes, immature dendritic cells, and eosinophils.
CCL3 is also known as stem cell inhibitor (SCI) and can inhibit the proliferation
of hematopoietic progenitor cells. CCL3 bioactivity contributes to tumor metastas
is and the inflammatory components of viral infection, rheumatoid arthritis, and
hepatitis, although it also can suppress the replication of HIV. CCL3 additionally
promotes hyperalgesia by sensitizing sensory neurons to TRPV1mediated
noxious stimulation.
