Web1 de mar. de 2024 · Tumor antigens are classified as either tumor-associated antigens (TAAs) or tumor-specific antigens (TSAs). TAAs are aberrantly expressed by, but are not specific to, cancer cells. Because normal tissue also expresses TAAs, albeit at lower levels, on-target off-tumor toxicities of immunotherapies that target TAAs are a concern. WebTumor antigen-specific T cells of autoantigens isolated from cancer patients usually have low affinity due to central tolerance. 85 As observed with CAR-T cells, the “on-target, off …

WebCEA Tmod cells use two receptors: a chimeric antigen receptor (CAR) activated by CEA and a leukocyte Ig-like receptor 1 (LIR-1)–based inhibitory receptor triggered by human leukocyte antigen (HLA)-A*02. CEA Tmod cells exploit instances of HLA heterozygous gene loss in tumors to protect the patient from on-target, off-tumor toxicity. WebChimeric antigen receptor (CAR) T cell therapies have led to on-target, off-tumour toxicity (OTOT) in clinical trials involving patients with solid tumours. Preclinical mouse models …

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”.
