Impairments of Antigen-Presenting Cells in Pulmonary Tuberculosis

Table 1

The phenotypic characteristics of monocytes obtained from peripheral blood of healthy donors and TB patients.

Markers (%)	Healthy donors	TB patients
		All patients	PPD-reactive patients	PPD-anergic patients
CD14^+CD16^+	8.9 ± 1.2 (15)	18.0 ± 1.2 (65)^*	15.4 ± 1.0 (39)^*	21.4 ± 2.4 (26)^*#
HLA-DR^+	84.1 ± 1.5 (10)	69.7 ± 1.8 (72)^*	69.8 ± 2.2 (50)^*	69.1 ± 3.7 (22)^*
CD86^+	66.1 ± 4.5 (9)	48.3 ± 4.9 (18)^*	48.6 ± 5.4 (12)^*	40.5 ± 4.6 (6)^*

The relative numbers of Mo (M ± S.E.) expressing different markers were presented in healthy donors and TB patients (the whole group), including PPD-reactive and PPD-anergic TB patients. The number of cases is indicated in parentheses. < 0.05 (Mann-Whitney -criterion) with healthy donors; ^# < 0.05 between PPD-reactive and PPD-anergic TB patients.
