WebNational Center for Biotechnology Information Web2.2. CAR Optimization: Costimulation and Signaling Domains. A comparative study of signaling and costimulation domains of the NK-specific molecules DAP10 (DNAX-activating protein of 10 kDa), FcεR1γ, CD3ζ 2B4, and 4-1BB found that in NK cells the best combinations were 2B4 with CD3ζ and 4-1BB with CD3ζ (Christodoulou et al. 2024a).

WebJan 19, 2012 · This tumor regression was similar to that achieved with CD28- or 4-1BB–costimulated CARs, and heightened persistence was similar to 4-1BB but greater than CD28. Thus, CD27 costimulation enhances expansion, effector function, and survival of human CAR-T cells in vitro and augments human T-cell persistence and antitumor … WebMar 6, 2024 · 4-1BB costimulation results in increased mitochondrial fusion and biogenesis via p38-MAPK We next wanted to determine the mechanism by which 4-1BB promotes increased mitochondrial content in T cells. To do this, we used short-term stimulation of T cells in vitro with 4-1BB agonist antibody.
WebOct 1, 2024 · AbstractPurpose:. 4-1BB (CD137) is a key costimulatory immunoreceptor and promising therapeutic target in cancer. To overcome limitations of current 4-1BB–targeting antibodies, we have developed PRS-343, a 4-1BB/HER2 bispecific molecule. PRS-343 is designed to facilitate T-cell costimulation by tumor-localized, HER2-dependent 4-1BB … WebMost studies have focused on the co-stimulatory domains CD28 or 4-1BB.
