Experimental HIV infection of human lymphoid tissue: correlation of CD4+ T cell depletion and virus syncytium-inducing/non-syncytium-inducing phenotype in histocultures inoculated with laboratory strains and patient isolates of HIV type 1.

Abstract excerpt

It is now apparent that HIV infection leads to a gradual collapse of a complex system of lymphoid tissue. This collapse tends to be associated with a change in virus tropism from macrophages to T lymphocytes, and a change in phenotype from nonsyncytium inducing (NSI) to syncytium inducing (SI). An experimental system is required to study the role of this change in HIV pathogenesis in lymphoid tissue. Here we...
