Differential expression of genes involved in T cell interactions. (A) Broadly, the CD32-high subset expressed lower levels of MHC genes, but higher levels of genes encoding multiple co-stimulatory molecules: CD40, 4-1BB, and OX40. (B) For every immunosuppressive gene except IL-10, the CD32-high cells consistently expressed a higher level than the CD32-mid cells. These included PD-L1, PD-L2, B7-H3, B7-H4, and FASLG. Since we could obtain only 3 sets of paired samples, these data were not subjected to a significance test.
