摘要: Interleukin 6 (IL-6) was originally identified as a B cell differentiation factor (BCDF/BSF2) which induces final maturation of cells into antibody producing (Hirano et al 1986). However, subsequent studies with recombinant molecules revealed that IL-6 has wide variety biological functions on various tissues and (Kishimoto 1989). As shown in Fig. 1, acts not only but also hematopoietic progenitors hepatocytes is involved hematopoiesis acute phase reactions. It nerve cells, epidermal keratinocytes kidney mesangium cells.
