Abstract: 【Abstract】 T helper 17 (Th17) cell /regulatory T (Treg)cell imbalance has been widely considered as one of immunopathogeneses of psoriasis. Mesenchymal stem cells (MSC) can inhibit the proliferation and differentiation of Th17 cells, but induce the proliferation of Treg cells. Exosomes secreted by MSC are a kind of important carrier for intercellular communication and material transportation. Studies have found that exosomes from MSC and MSC have similar immunoregulatory function, which can inhibit the proliferation of Th17 cells and induce the differentiation of Treg cells. In recent years, many studies have shown that abnormalities of MSC in bone marrow and skin lesions of psoriasis patients are related to the occurrence of psoriasis, but the mechanism is still unclear. This review elaborates the role of normal MSC and their exosomes in the maintenance of Th17/Treg balance, which provides ideas for studying how abnormalities of MSC in bone marrow and skin lesions of psoriasis patients participate in the occurrence of psoriasis.
