Tumor-specific antigen-presenting pathway

Molecular classification
Pathway, Immune Pathway, Antigen Presentation
01

Overview

The tumor-specific antigen-presenting pathway refers to the cellular mechanisms by which tumor cells process and present antigens—particularly those unique or highly specific to tumors (tumor-specific antigens, TSAs)—to the immune system. This pathway is crucial for immune recognition of cancer cells and underpins many immunotherapeutic strategies. Defects in this pathway can lead to immune evasion. Therapies aim to restore the function of the pathway to improve anti-tumor immunity.
