Anti-Apoptotic c-FLIP Reduces the Anti-Tumour Activity of Chimeric Antigen Receptor T Cells.

CAR T cell treatment of solid tumours is limited by poor persistence partly due to CD95 ligand (CD95L)-induced apoptosis. Both T cells and cells within the tumour microenvironment (TME) may express CD95L, triggering apoptosis in CD95-receptor-positive CAR T cells. Tonic signalling of CAR T cells may also increase CD95-dependent AICD.

Chimeric antigen receptor T cell persistence and memory cell formation.

It is now becoming clear that less differentiated naive and memory T cells are superior to effector T cells in the transfer of immunity for adoptive cell therapy. This review will outline the challenges faced by chimeric antigen receptor (CAR) T cell therapy in the generation of persistence and memory for CAR T cells, and summarize recent strategies to improve CAR T cell persistence, with a focus on memory cell formation. The relevance of enhancing persistence in more differentiated effector T cells is also covered, because genetic and pharmacological interventions may prolong effector T cell activity and lifespan, thereby improving anti-cancer activity.

An EBV-based plasmid can replicate and maintain in stem cells.

Viral vectors have a wide range of applications in biology, particularly in gene therapy. Based on their integration capacity, viral vectors are classified as either integrating or non-integrating vectors. Although integrating vectors, such as lentivectors, have the ability to direct prolonged expression of exogenous genes, manipulation of the host genome is an inappropriate feature of these gene delivery tools.

The Role of microRNAs in Stemness of Cancer Stem Cells.

Cancer is one of the most important diseases of humans, for which no cure has been found so far. Understanding the causes of cancer can pave the way for its treatment. Alteration in genetic elements such as oncogenes and tumor suppressor genes results in cancer.
