Decade-Long Safety and Function of Retroviral-Modified Chimeric Editor's Summary

up engineered T cells as a delivery platform for therapeutics. specific, opening−involved in growth control or transformation. Thus, the safety of retroviral vectors may be cell type evidence of integration-induced immortalization, with no observable enrichment of integration sites near genes of engraftment, and did not require host immunosuppression before transplant. Moreover, the authors found no infusion at levels higher than those induced by standard vaccines. These cells were still functional, had stable levels carrying a chimeric antigen receptor. They found that these cells were present in recipients over a decade after The authors followed patients from three clinical trials who received T cells transduced with gammaretroviruses and that these cells may persist over a decade in patients. mediated gene transfer in T cells may not have the same safety concerns, − report that retroviral vectoret al.Scholler genome. However, some patients in early trials developed leukemia because of insertional mutagenesis. Now, Retroviral vectors were once the mainstay of gene transfer because they could stably integrate into the host Standing the Test of Tim
