 AB    Human immunodeficiency virus (HIV) replication and T cell proliferation
       were investigated in situ by a PCR-based analysis of individual
       microdissected splenic white pulps. Founder effects, revealed by an
       exquisite compartmentalization of HIV genotypes and T cells, indicated
       the recruitment of latently infected CD4+ T cells through highly
       localized antigen presentation rather than the infection of CD4+ T
       lymphoblasts by blood-borne virus or immune complexes. HIV-infected
       white pulps could be infiltrated by HIV-specific cytotoxic T
       lymphocytes, thereby implicating them in CD4+ T cell destruction in
       vivo. Together these data describe an iterative and deleterious
       mechanism of antigen-driven T cell recruitment and activation, as well
       as HIV replication and spread, with consequent destruction of the newly
       infected cells.
