Cancer-associated fibroblast activity (TGFβ₁ production)

Molecular classification
Cytokine production, Cellular process, Growth factor signaling
01

Overview

Cancer-associated fibroblast activity, specifically the production of TGFβ₁, is a key driver of tumor progression. TGFβ₁, secreted by CAFs, induces myofibroblast differentiation, promotes extracellular matrix remodeling, modulates the immune response, enhances metabolic support for cancer cells, and drives therapy resistance. Targeting this activity represents a potential therapeutic strategy.
