pubmed:abstractText
Peripheral blood monocyte (MO) subpopulations isolated on a basis of functional expression or a lack of Fc receptor (FcR+ and FcR- MO) were used to study the regulation of the antigen (PPD)-driven lymphoproliferation. Long-term cultures of T lymphocytes with FcR+ MO, but not FcR- MO, led to the induction of T suppressor (Ts) cells that inhibited antigen-driven lymphoproliferation in the test cultures. These Ts cells were resistant to mitomycin C, belonged to afferent-acting category of Ts cells, expressed CD8 and HLA-DR determinants, and showed no antigenic specificity nor genetic restriction in action. The expression of MHC class II molecules (HLA-DR and HLA-DP but not HLA-DQ determinants) on MO which were used for antigen presentation was critical for Ts cell induction. It was concluded that specialized MO subpopulations may regulate the lymphoproliferation by inducing Ts cells (or Ts cell circuit) that in turn inhibit antigen-driven immune response.
