Cytokine production in primary cultures obtained from mono-HTLV-II–infected patient PR-1 and from HIV-1/HTLV-II–coinfected patient PR-11.

Results are representative of 3 separate experiments. Patients' PBMCs were cultivated in the absence (A) or presence (B) of IL-2. Supernatants were harvested at various times and tested for cytokine content.
