Abstract
Several members of the cytokine network play an important role in controlling the replication of the human immunodeficiency virus (HIV) in several experimental systems, Their effects can be categorized in the following three functional groups: (1) HIV-inductive cytokines; (2) HIV-suppressive cytokines; (3) cytokines with both activating and inhibiting capacities, Studies on the mechanism of action of these molecules have highlighted the fact that several steps of the retrovirus life cycle, from binding to budding of progeny virions from the infected cell, are affected by cytokines, This general concept has been recently substantiated by the discovery that certain beta-chemokines can act as blockers of viral entry by interfering with HIV co-receptors, Finally, it is important to recognize that cytokines have gone beyond their role as potential pathogenetic or protective endogenous cofactors in HIV replication and disease progression, and are becoming experimental therapeutic agents for HIV disease, best illustrated thus far by the case of interleukin-2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
