- AB It was our objective to investigate the effect of asymptomatic infection
- with HIV on the expression of lymphocyte activation markers after
- stimulation with mitogens. Whole blood cultures were made of HIV+ and
- HIV- subjects (29 asymptomatic HIV-1-infected subjects and 33 apparently
- healthy normal volunteers). At various times after stimulation with
- concanavalin A (Con A), anti-CD3 and pokeweed mitogen (PWM), the
- expression of activation markers (CD25 and HLA-DR) and the blastogenesis
- were quantified by flow cytometry. The flow cytometric quantification of
- the expression of activation markers and blastogenesis in whole blood
- cultures provided an easy and safe alternative to thymidine
- incorporation to assess lymphocyte responses in HIV+ subjects.
- Activation showed a tendency to be lower in the HIV+ subjects with all
- three stimulants. This difference with HIV- subjects was statistically
- significant only for stimulation with PWM after 4 days. Further
- investigations should be undertaken to show whether this functional
- impairment is related to disease progression and whether it can be
- influenced by effective therapy.
