    Abstract:
    Cytokines are produced by various types of cells and have profound effects on the regulation of immune reactions, hematopoiesis, and inflammation. Herein, we will discuss the pathophysiological relevance of cytokine receptor expression, particularly focusing on chemokine receptor expression. Chemokines are cytokines with 4 cysteines at the well-conserved positions and exhibit potent chemotactic activities for various types of leukocytes. To date, accumulating evidence has indicated the potential involvement of these chemokines in inflammatory reactions through regulating inflammatory cell infiltration. Moreover, several lines of evidence demonstrate that different sets of chemokine receptors are expressed by T helper type 1 (Th1) and Th2 cells and that Th1 and Th2 cells respond to distinct sets of chemokines. These observations establish the essential roles of chemokines in helper T lymphocyte migration in vivo. Furthermore, several chemokine receptors are utilized as co-factors for human immunodeficiency virus entry and mutation in one chemokine receptor confers marked resistance to HIV infection. Therefore, the determination of chemokine receptors may provide invaluable information on the immune status and susceptibility to HIV infection.
