Cytokines and bacterial infections.

During the recent 10-15 years a growing amount of knowledge has been accumulated on the role of cytokines in the pathogenesis and resistance to infections caused by nonviral agents, including a wide range of bacteria. Cytokines can be major mediators of the pathogenic effect in some diseases, and represent important defense mechanisms in others. Detailed knowledge on the role of the growing number of recognised cytokines is important, because it may represent means to combat and to prevent diseases caused by such infections.
