Phenotypic characterization of lymph node DC of CD4C/HIV^MutA transgenic mice^a

Marker	No. of expt	Age (mo)	Mean fluorescence intensityb ± SEM	Pc
MHC class II	16	2-4	1.5 ± 0.1	<0.001
CD40	8	2-4	1.4 ± 0.1	0.042
B7-2	13	2-4	1.2 ± 0.1	0.041

^aFACS analysis. Each experiment was done with pooled sex-matched transgenic (n = 3) and control nontransgenic (n = 3) littermates.

^bThe data are expressed as the ratio of nontransgenic to transgenic DC.

^cStudent's t test for single samples.
