Usefulness of liver infiltrating CD86-positive mononuclear cells for diagnosis of autoimmune hepatitis

Table 1 Analysis of costimulatory molecules expressed on PBMCs (mean ± SD)

	Control n = 25	AIH Patients n = 34	P value
CD80	41.3 % ± 7.04 %	32.7 % ± 23.5 %	0.008
CD86	1.15 % ± 1.19 %	0.78 % ± 0.75 %	0.04
CD152 CTLA-4	13.8 % ± 10.9 %	2.32 % ± 2.80 %	0.01

The P values calculated by a Mann-Whitney’s U-test are shown. Compared to the healthy controls, CD80+, CD86+ and CD152+ PBMC of the patients with AIH are shown to be significantly fewer.
