Immune tolerance induced by bone marrow cell infusion / 中国组织工程研究

ABSTRACT

OBJECTIVE: To summarize the study of bone marrow cell infusion-induced immune tolerance. METHODS: The Pubmed database was researched using the computer for articles published from January 2000 to December 2008 using the key words of "bone marrow cells, transplantation immune tolerance" in English. Simultaneously, Chinese Biomedical Literature Database and China Journal Full-text Database were retrieved for articles published from January 2000 to December 2008 using the key words of "bone marrow cells, immune tolerance" in Chinese. Besides, Organ Transplantation, Transplantation Immune Tolerance and Conference Proceedings of English and Chinese were retrieved by hand. Inclusion criteria relevant mechanism of immune tolerance; scheme of bone marrow cell infusion-induced immune tolerance; advantages and disadvantages of bone marrow cell infusion-induced immune tolerance; articles in the same circle published in recent years or in authorized journals. Exclusion criteria repetitive studies or irrelevant articles. RESULTS: Mechanism of immune tolerance comprised cleaning, inability, regulation or inhibition, and ignorance. The scheme of bone marrow cell infusion-induced immune tolerance mainly contained bone marrow cell infusion combined with myeloablative pretreatment, bone marrow cell infusion combined with non-myeloablative pretreatment, pretreatment with immunosuppressive drug or chemotherapeutics, pretreatment of costimulatory signaling blockage, bone marrow cell combined with mesenchymal stem cell infusion. Bone marrow cell infusion-induced immune toleranca could induce long-lasting stable specific immune tolerance by effective immune tolerance mechanism, and had been an effective main method for inducing transplanted tolerance. CONCLUSION: Up to now, clinical immune tolerance is still uncontrollable and facultative. Bone marrow cell infusion-induced stable immune tolerance can develop a new space for organ transplantation.
