Production of MIP-1α, MIP-1β, and RANTES (pg/ml) by unfractionated, CD8⁺, and CD4⁺ PBMC from three HIV-infected subjects

MIP-1α
1	40	7,418	10	2,693	10	3,835
2*	13	1,531	10	4,396	10	733
3	10	8,138	224	3,201	1729	6,580
MIP-1β
1	838	19,305	59	20,975	46	20,308
2*	104	24,928	123	28,357	19	4,094
3	10	29,773	171	23,759	1738	28,557
RANTES
1	10	4,759	10	1,914	10	1,742
2*	10	2,739	10	2,383	10	185

β-chemokine production in culture supernatants was assessed on day 5 post-stimulation. 

^*CD4⁺ and CD8⁺ cells were obtained by positive selection using immunomagnetic beads rather than by negative selection.
