B cells Inhibit B cell proliferation, differentiation
DC cells Impaired antigen presentation
Production of anti-inflammatory cytokines (IL-10)[31]
Decrease TNFa,
Decrease the expression of HLA-DR on myeloid dendritic cells[41]
NK cells Inhibiting the proliferation of NK cells and cytokine production
T cells Inhibit the proliferation of T lymphocytes,
Promote the generation of CD4+ T regulatory cells (Treg)[23]
Switch CD4+ T cell responses from a Th1 to a Th2 polarized phenotype
Induction of Th1 drop INF Gamma
Induction of Th2 increase IL.4
