 AB    A complex array of immunopathogenic mechanisms that are multiphasic and
       multifactorial are involved in the establishment and progression of HIV
       disease. Following primary infection, an acute viremia occurs with wide
       dissemination of HIV. During this early viremic phase, virus enters the
       lymphoid tissue, trapped within the processes of follicular dendritic
       cells. In addition, during this phase of primary infection certain
       patients show major expansions of certain V beta subsets of CD8+ T cells
       which are manifestations of responses to HIV and which may be associated
       with both protective and harmful effects. Thus, events that occur soon
       after initial infection with HIV are critical to the subsequent course
       of HIV disease and may be extremely important in the control of the
       progression of HIV infection. In addition, inappropriate immune
       activation and elevated secretion of certain immunoregulatory cytokines
       occur during HIV infection. These cytokines play a role in the
       regulation of HIV expression in the tissues and, ultimately, influence
       the course of disease. In studies of HIV-infected individuals who are
       long term non-progressors despite up to 11 years of infection, it was
       found that these patients have preserved lymph node architecture, low
       viral burden and viral expression compared to individuals who are
       infected for comparable periods of time, but who progress in their HIV
       disease. The implications of host factors in the immunopathogenesis of
       HIV disease will be discussed.
