WebNov 12, 2024 · Somatic recombination is a type of gene rearrangement by which cells of the adaptive immune system physically cut out small regions of DNA and then paste the remaining pieces of DNA back together in an error-prone way. Because there are many ways to cut and paste the DNA, and because repairing a cut is imperfect and allows for the …

WebHere, we propose a novel immunotherapy approach, allowing safe and efficient engineering of B cells and T cells, both ex vivo and in vivo. We will use adeno associated vectors (AAV) to integrate chimeric antigen receptor (CAR) or T cell receptor (TCR) genes into loci coding TCR chains and to integrate antibody (Ab) genes into loci coding Ab chains. WebMay 14, 2024 · Abstract. Purpose: The adoptive transfer of lymphocytes genetically modified to express tumor reactive T-cell receptors (TCR) can mediate tumor regression. Some tumor-infiltrating lymphocytes (TIL) recognize somatic mutations expressed only in the patient's tumors, and evidence suggests that clinically effective TILs target tumor …
Die V(D)J-Rekombination (auch als somatische Rekombination bezeichnet) ist ein genetischer Umlagerungsprozess an der DNA von Wirbeltieren, der für die Variabilität der von den B-Zellen gebildeten Antikörper (auch Immunglobuline genannt), der B-Zell-Rezeptoren, sowie der T-Zell-Rezeptoren sorgt. Sie spielt eine entscheidende Rolle für das adaptive Immunsystem, indem sie die Erkennung einer Vielzahl von Antigenen bakterieller, viraler oder parasitärer Herkunft ermöglicht.
