On-target/off-tumor
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-tumor” response occurs when TCR-T cells are infused, due to the expression of the same antigen on normal tissue, and the infused TCR-T cells also induce the occurrence of … WebThe conventional CAR structure has limitations including on-target/off-tumor effects, weak CD3ζ motif activation, and cytokine release syndrome. Researchers are exploring new avenues to develop CAR-T cells, including specific tumor-associated antigens, costimulatory signaling, and distinct immune cells.

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. Web17 de abr. de 2024 · A direct consequence of CAR-T hyperactivation is the “on target toxicity”, which is mostly related to abundant cytokine release. On the other hand, the “off-target toxicity” is due to the inability of ScFv to distinguish between tumor antigens (expressed on tumor cells) and normal antigens (expressed on normal cells).
WebA major risk and the direct cause of adverse effects reported in clinical and preclinical trials is off-tumor, on-target toxicity due to expression of the target antigen on nontumor tissues. WebCAR-T cells have revolutionized clinical therapy, but their application in solid tumors is hindered by various challenges such as mutated antigens, physical barriers, and the …
WebWhen the expression of the target antigen is similar between human and mouse, but the antihuman antibody does not recognize the murine orthologue, on-target, off-tumor toxicity against healthy tissues expressing the molecule of interest can only be addressed in syngeneic models ( figure 2 ).
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. cschai-suWeb13 de dez. de 2024 · On-target, off-tumor toxicity Noting that high-dimensional data have not been routinely utilized in the pre-clinical study of targeted therapies, we emphasize that most of our understanding of toxicity has been derived through clinical observations from early-stage clinical trials. cschah winnipegWeb16 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 ). csc halle contactWebOn-target off-tumor effects Targeting tumor-restricted post-translational modifications ∙Four major CAR-T cell targets have been investigated: TAG72 28 , B7-H3 55,56 , MUC1 16 , and MUC16 57,58 . dyson airwrap complete long haarstyler kaufenWebIn the context of oncology, decrease in tumor size could be considered a surrogate endpoint, while longer survival would be a clinical endpoint.
