L-selectin and CD11b/CD18 expression at the surface of resting monocytes from HIV-infected patients and healthy controls^a

Patient group	Mean fluorescence intensity ± SEMb for:
	L-selectin	CD11b	CD18
Controls	86.4 ± 7.7	30.7 ± 2.1	30.7 ± 1.8
Group 1	50.9 ± 6.6*	45.6 ± 3.8*	43.5 ± 4.0*
Group 2	64.3 ± 5.0*	46.2 ± 3.1*	41.9 ± 2.9*
Group 3	65.8 ± 7.7*	56.8 ± 5.2*	44.7 ± 3.5*

^aWhole-blood samples maintained at 4°C were incubated with anti-LAM1.3, anti-CD11b, or anti-CD18 antibodies for 30 min at 4°C, and the mean fluorescence intensity was recorded as described in Materials and Methods. Values obtained with an irrelevant antibody of the same isotype were subtracted. 

^b*, significantly different from control values (P < 0.05).
