Gene Therapy
Researchers at University College release new data on gene therapy
July 1st, 2008
"The latent membrane protein-2 (LMP2) of Epstein-Barr virus is a potential target for T-cell receptor (TCR) gene therapy of Hodgkin lymphoma and nasopharyngeal carcinoma. Here, we modified a human leukocyte antigen-A2-restricted, LMP2-specific TCR to achieve efficient expression following retroviral TCR gene transfer," investigators in London, the United Kingdom report. "The unmodified TCR was poorly expressed in primary human T cells, suggesting that it competed inefficiently with endogenous TCR chains for cell surface expression. In order to improve this TCR, we replaced the human constant region with murine sequences, linked the two TCR genes using a self-cleaving 2A...
