Sv. Joag et al., EARLY ACTIVATION OF PBMC AND APPEARANCE OF ANTIVIRAL CD8-INDUCED DISEASE IN RHESUS MACAQUES( CELLS INFLUENCE THE PROGNOSIS OF SIV), Journal of medical primatology, 23(2-3), 1994, pp. 108-116
We studied 15 macaques inoculated with SIV and identified three phases
of infection. Phase 1 was characterized by activated lymphocytes in b
lood and infected cells in the CSF. In phase 2, activated cells were n
ot detected but virus was recovered from mitogen-stimulated PBMC, whil
e in phase 3, virus was recovered from mitogen-stimulated PBMC only af
ter depletion of CD8+ lymphocytes, indicating effective control of the
virus in peripheral blood. Early development of phase 3 status correl
ated with a longer period of clinical normalcy.
