Abstract:

BACKGROUND: mmunorelated pancytopenia involves in multiple clinical disciplines and has been paid more and more attention in recent years. Autoantibodies on bone marrow hematopoietic stem cells and immune regulation function may be the crux of the problem.
OBJECTIVE: To study the progress on the role of bone marrow hematopoietic stem cell-associated antibodies in the pathogenesis of immunorelated pancytopenia.
METHODS: A computer retrieval of PubMed, WangFang Med Online and CHKD database was conducted for articles regarding the autoantibodies on bone marrow hematopoietic stem cells published from March 1992 to March 2012. The keywords were “immunorelated pancytopenia, bone marrow hematopoietic cells, autoantibody, T helper 17 cells”. Repetitive articles were excluded, and finally 30 articles were included in result analysis.
RESULTS AND CONCLUSION: The production of autoantibodies on bone marrow hematopoietic cells is due to the imbalance in T lymphocyte regulation resulting in abnormal quantity and function of B lymphocyte and its subset. They destroyed or inhibited the differentiation and maturation of bone marrow hematopoietic cells, leading to a reduction of peripheral blood cells eventually. The increasing number of T helper 17 cells and the hyperfunction of T helper 17 cells may be associated with the production of autoantibodies in patients with immunorelated pancytopenia, which is an important factor for the pathogenesis of immunorelated pancytopenia.
