TABLE 3.

Percent specific lysis of IIIB-infected CEM.NKR cells by total PBMC and PBMC depleted of different cell types in the presence of pooled, human seropositive sera (10⁻³ dilution)

Expt no.	E/T ratio	% Specific lysis for indicated effector cell populationa
		Total PBMC	CD56+-depleted PBMC	CD19+-depleted PBMC	CD14+-depleted PBMC
1	100	32 ± 1	5 ± 2	24 ± 4	25 ± 5
2	100	34	4	31	34

^aEffector cell populations were prepared as described in Materials and Methods. Errors represent the standard deviations of triplicate measurements.
