Web1 de mar. de 2024 · Because normal tissue also expresses TAAs, albeit at lower levels, on-target off-tumor toxicities of immunotherapies that target TAAs are a concern. Conversely, TSAs are found only on cancer cells. MANAs are a subclass of TSAs and are derived from the expression of common hotspot mutations in cancer genes. Web15 de jul. de 2024 · Although a variety of CAR molecules have been developed so far, the clinical application for solid tumors is limited partly due to its adverse effect known as “on-target off-tumor toxicity”. Therefore, it is very important for CAR T cell therapy to target specific antigens exclusively expressed by malignant cells.

Preclinical mouse models … WebAlternatively, off-target off-tumor toxicity can occur due to cross-reactive binding to a mimotope, which is a similar but distinct epitope expressed on normal tissues. This cross-reactivity or ‘off-target’ binding to cell surface proteins is difficult to predict in preclinical animal studies and can lead to serious adverse effects in patients.

Web16 de jun. de 2024 · On-target, off-tumor toxicity can be reduced by using CAR targeting systems that can improve the recognition of tumor cells ( 5 ). One such strategy is to affinity-tune CARs so they detect tumor cells with a high density of surface antigens and do not react against normal cells that have low antigen densities ( 6 ).
