Cell cycle analysis of HIV-1-infected and uninfected CD4⁺ T cells^a

Time (days) p.i.b	HIV-1 status	% of cells in:
		G1	G2/M	S	Apoptosis
0	−	71	11	17	1
4	−	82	6.4	6.2	5.2
	+	81	7.2	6.0	5.4
7	−	70.8	4.4	2.3	22.9
	+	66.6	4.8	2.6	26
10	−	66.4	4.2	2.6	26.8
	+	59	3.5	2.0	35.5

^aCell cycle analyses based on DNA content per cell were performed as described in Materials and Methods; 20,000 cells were analyzed. Data shown are representative of three separate experiments from individual normal donors. 

^bDays postinfection (p.i.) of PHA-activated CD4⁺ T cells purified, activated, and infected as described in Materials and Methods. Day 0, time of infection, 3 days after PHA activation.
