The spleen and lymph nodes are major sites of human immunodeficiency virus type 1 (HIV-1) replication, mutation, and genetic variation in vivo. If a major portion of the lymphatic tissue, such as the spleen, is removed or otherwise is unavailable for invasion by the HIV-1 virus, will the course of t

β¦ Synopsis
Many viruses have evolved novel means of exploiting host defense mechanisms for their own survival. This exploitation may be best exemplified by the interrelationships between certain viruses and the host cytokine networks. Many viruses, including the human immunodeficiency virus type-I (HIV-1 ), rely on the liberation and cellular action of host immune cytokines to expand their host cell range, to regulate their cellular expression, and to maintain their dormant state until the proper extracellular conditions arise. As again exemplified by HIV-1, viruses may also take an active role regulating cytokine expression and cell surface cytokine receptors. Because the viral life cycle, and in particular the HIV-1 life cycle, is so intertwined with cytokine regulatory networks, these networks represent potential points for therapeutic intervention. As our understanding of cellular cytokine pathways involved in viral infection and replication continues to expand, so too will our ability to design rational anti-viral therapies to alter multiple steps along the viral life cycle.

Cytokines have been recognized to play an important role both in normal development of the brain, when they act as neurotrophic factors, as well as following injury. While both the cytokines and their receptors are synthesized and expressed in the brain normally (albeit at low levels), it has become
## Abstract The effects of herpesviruses infection on the progression of HIV disease remain controversial, with some studies showing accelerated progression and others showing no effect. Furthermore, the effect of concurrent infection with more than one herpesvirus on the progression of HIV disease
Recent studies suggest that the pathogenesis of HIV infection and AIDS involves two distinct phases. During acute infection, massive depletion of CD4 + CCR5 + memory T cells within the mucosal-associated lymphoid tissue leads to major and potentially irreversible damage to CD4 + T-cell-mediated immu
