Tumor Necrosis Factor-Like Weak Inducer of Apoptosis Receptor (Fn14)

Target: Fn14
Molecular classification: Receptor, TNF receptor superfamily

Overview

The tumor necrosis factor-like weak inducer of apoptosis receptor—Fn14—is a key mediator of cellular responses to stress via the TWEAK ligand. It orchestrates diverse processes including cell proliferation/apoptosis balance and inflammatory/fibrotic responses. Its dysregulation is implicated across neurological injuries/diseases as well as cardiovascular pathology—making it an attractive target for therapeutic intervention aimed at limiting tissue damage due to excessive inflammation or inappropriate cell death/proliferation signals.

Other names: Fibroblast growth factor-inducible 14
