Therapeutic T cell engineering

Sadelain, M., Rivière, I. & Riddell, S. Therapeutic T cell engineering. Nature 545, 423–431 (2017). 

1. CAR co-stimulatory 1) CD28: T cell proliferation, glucose metabolism, self-limited T cell persistence
                                    2) 4-1BB: less potent, but lipid oxidation, great T cell persistence  

2. antigen: Antigen expression 을 다르게 인식하도록 engineering

3. EGFRvIII in glio → heterogeneity in expression → Low efficacy

4. Immunosuppressive TME: hypoxia, acidification, nutrient shortage, PD-L1, IL10, TGFb, IDO → how to overcome? IL-12 or 4-1BBL (armored CAR)

5. T cell phenotype selection: TN, TSCM, TCM
