Phenotyping of P105-Negative B Cell Subsets in Patients with Systemic Lupus Erythematosus
Figure 1
Subsets of RP105(−) B cells. (a) Representative flow cytometric profiles of RP105 expression on CD19(+) B cells from an active SLE patient and a normal subject. The population was subdivide (1) subset 1; CD19(+)RP105(int), (2)subset 2; CD19(+)RP105(−), and (3) presubset; CD19(low)RP105(−). (b) CD138 levels after gating CD19(low)RP105(−) presubset. The presubset cells were further subdivided into 3 subpopulations, subset 3; CD138(−), subset 4; CD138(int) and subset 5; CD138(++). (c) The percentages of subsets in PB of each patient and normal subject. *,.
