简要总结
The prognosis of patients with relapsed and/or refractory T-cell hematologic malignancies is poor due to lacking sufficient treatment.Anti-CD(cluster of differentiation antigen)19 CAR(chimeric antigen receptor)-T cell therapies are efficient for patients with B-cell hematologic malignancies. As for T-cell hematologic malignancies, CD7 is a promising target expressed on most malignant T cells. The outcome of CD-7 CAR-T cell therapy pre-clinical experiments is cheerful.however, how to select the functional T cells from the malignant T cells is a challenge. In addition to this, auto-CAR-T cell therapy is not affordable for the majority of patients. Using T cells aphesis from healthy donors edited to avoid rejection of the host as the material of anti-CD7 universal CAR-T cells could be accessible and affordable, which is adapted for patients with CD7+ relapsed and/or refractory T/NK-cell hematologic malignancies.
