Proliferative activity of T cells retrieved from the lung of patients with HIV infection after stimulation with IL-15 and TNF-α and with different anti–IL-2R MoAbs. Anti-CD122 MoAb but not anti-γc MoAb inhibits the stimulatory activity of IL-15–mediated T-cell proliferation. A combination of CD122 and TUGh4 MoAbs abolished the IL-15–mediated proliferative activity.
