The Role and Mechanism of TCR-T Cells in Immunotherapy for Acute Myeloid Leukemia

Summary

Acute myeloid leukemia (AML) is the main type of leukemia, accounting for about 60% of all leukemia, with complex pathogenesis and great clinical heterogeneity. Effective targets for AML need to be further developed. We performed next-generation sequencing analysis of the TCR sequence of an AML patient to find the patient's specific TCR clone for leukemia. The rearranged TCR gene stimulated by leukemia antigens was transduced into the patient's own T cells, and the TCR gene-modified T cells (TCR-T) that could specifically recognize leukemia antigens and kill leukemia cells were constructed. Enhancing the specificity and killing activity of T cells can truly achieve individualized treatment for patients. In addition, through TCR sequencing, the TCR sequence database of leukemia patients can be constructed to find the common specific TCR clones for AML among different patients, which can realize the precise treatment of AML.
