AB CD8 lymphocytes from asymptomatic human immunodeficiency virus (HIV)
type 1-infected patients can suppress virus production from infected CD4
cells. Suppressive activity is separate and distinct from cytotoxic T
lymphocyte (CTL) reactivities and is likely mediated by a soluble
factor(s). The majority of HIV-1 suppression studies have been done in
the context of bulk CD8 cell cultures. In this study, viral suppression
was characterized by clonal populations of CD8 cells derived from
HIV-1-infected patients. Most of the suppressive clones were devoid of
detectable CTL reactivity against env-, gag-, pol-, and nef-expressing
targets. Among the suppressive clones derived from an individual
patient, a marked heterogeneity was evident with respect to phenotypic
markers, cytokine production, and T cell receptor V beta expression.
These results suggest that noncytolytic virus suppression is oligoclonal
in nature. Clones provide tools for future studies aimed at
understanding the mechanism of suppression and identifying the
suppressive factor.
