Monocyte chemoattractant protein-1 (MCP-1): an overview.

Chemokines constitute a family of chemoattractant cytokines and are subdivided into four families on the basis of the number and spacing of the conserved cysteine residues in the N-terminus of the protein. Chemokines play a major role in selectively recruiting monocytes, neutrophils, and lymphocytes, as well as in inducing chemotaxis through the activation of G-protein-coupled receptors. Monocyte chemoattractant protein-1 (MCP-1/CCL2) is one of the key chemokines that regulate migration and infiltration of monocytes/macrophages.

Ciliary neurotrophic factor and interleukin-6 differentially activate microglia.

Studies have shown that cytokines released following CNS injury can affect the supportive or cytotoxic functions of microglia. Interleukin-6 (IL-6)-family cytokines are among the injury factors released. To understand how microglia respond to IL-6 family cytokines, we examined the effects of ciliary neurotrophic factor (CNTF) and IL-6 on primary cultures of rat microglia.

Angiocidin promotes pro-inflammatory cytokine production and antigen presentation in multiple sclerosis.

Angiocidin was originally identified as a potent inhibitor of angiogenesis and tumor growth in vivo. In addition to its involvement in the regulation of carcinogenesis, recent studies indicate that angiocidin may also play a significant role in immune system modulation. This report describes the expression and potential function of angiocidin in multiple sclerosis (MS), a severe demyelinating, inflammatory and autoimmune disease of the central nervous system (CNS).

Minocycline modulates chemokine receptors but not interleukin-10 mRNA expression in hypoxic-ischemic neonatal rat brain.

Hypoxic-ischemic (HI) brain injury in the perinatal period causes significant morbidity. Minocycline (MN) is a tetracycline derivative that has reduced brain injury in various animal models of neurodegeneration, including perinatal ischemia. To determine whether MN can modulate the expression of chemokine receptors and interleukin-10 (IL10) in a model of neonatal brain injury, we produced an HI insult to the right cerebral hemisphere (ipsilateral) of the 7-day-old rat (PD7) by right common carotid artery ligation and 2.
