Hage inflammatory protein-1a, also referred to as chemokine (C-C motif) ligand 3, is an inflammatory chemokine and is involved in atheroscleroticExperimental Molecular Medicinelesion formation with an acute inflammatory state.25 sTNF-Rs, which are pro-inflammatory cytokines, have an affinity for TNF and compete with membrane-bound TNF-Rs to bind the ligand. They contribute to a counter-regulatory response to excessive TNF activity.26 LIX is identified as a C-X-C motif chemokine five (CCL5) and as RNATES (regulated on activation, regular T-cell expressed and secreted). LIX is often a chemotactic cytokine involved in recruiting leukocytes into inflammatory lesions.27 The present report demonstrates the regulation on the balance in between M1 and M2 in macrophages by MSCs might result inside a favorable atmosphere to accommodate therapeutic MSCs.
