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.
