Neoantigen-Specific Immune Response

Molecular classification
Immune response, Adaptive immunity
01

Overview

A neoantigen-specific immune response is an adaptive reaction primarily mediated by cytotoxic T-cells recognizing mutation-derived peptides exclusively presented on cancerous tissue. This mechanism underpins several promising personalized immunotherapy strategies due its high specificity and strong immunogenic potential without significant risk for autoimmunity or damage to healthy tissues.
