    A chronically HIV-1-infected T cell clone (J1.1) derived from Jurkat cells was developed that possesses defects in CD3 signaling. This clone was phenotypically determined to be CD4- and express a reduced surface density of CD3 as compared with a pool of uninfected Jurkat clones. Although J1.1 could be induced with TNF-α to produce HIV-1 particles, stimulation via the CD3 (T3-Ti) complex, using mAb cross-linking, had no effect on viral production. Further investigation revealed that J1.1 secreted approximately 20-fold less IL-2 than did uninfected Jurkat cells after anti-CD3 treatment. In addition, a separate defect in Ca2+ mobilization was noted in the HIV-1-infected J1.1 line when compared with uninfected Jurkat cells after anti-CD3 cross-linking. The cell line described offers a new model in which to study the mechanisms of several defects directly imposed by HIV-1 on CD3+ cells.
