Abstract
In this paper, we discuss the potential involvement of a new family of cytokines, termed chemokines, in CNS inflammatory pathology. Chemokines are a family of proinflammatory cytokines which are able to stimulate target-cell-specific directional migration of leukocytes. Because of this feature, chemokines may be potent mediators of inflammatory processes. We have previously reported observations indicating that chemokines may be involved in the process of lesion formation during autoimmune inflammation within CNS, and, in particular, are likely participants in the process of influx of inflammatory cells into the CNS parenchyma. We observed also that mechanical injury of brain and subsequent post-traumatic inflammation may in part be mediated by chemokines. Chemokines undoubtedly co-operate with cell-associated adhesion molecules during recruitment of leukocytes from blood to CNS. The sequential expression of soluble and membrane-bound signals for leukocyte migration is an intricate process that can be interrupted by a variety of strategies. Our data suggest that chemokines may represent a promising target for future therapy of inflammatory conditions, including CNS inflammation resulting from varied insults.
