Activity summary

TRAIL also known as TNF-related apoptosis-inducing ligand plays an important role in inducing apoptosis. This protein has a mass of around 32 kDa and is expressed across various tissues including immune cells. TRAIL interacts with specific receptors on the cell surface to initiate a signaling cascade that results in programmed cell death. It is an attractive therapeutic target because of its selective ability to induce apoptosis in cancer cells while sparing most normal cells.

Biological function summary

TRAIL's function extends beyond inducing cell death. It is an important member of the tumor necrosis factor (TNF) superfamily which regulates immune responses and inflammation. TRAIL can form a homotrimeric complex allowing it to bind effectively to death receptors on target cells specifically DR4 and DR5 triggering a series of downstream signaling events. This interaction is significant in modulating immune surveillance and tumor suppression.

Pathways

TRAIL is integral to both intrinsic and extrinsic apoptosis pathways. Through these pathways TRAIL is closely related to FADD and caspase-8 which are important for apoptosis induction. The extrinsic pathway involves binding to TRAIL death receptors leading to DISC formation while the intrinsic pathway involves mitochondrial events mediated by members of the Bcl-2 protein family.

Associated diseases and disorders

TRAIL has a significant connection with cancer and autoimmune diseases. TRAIL plays a dual role in cancer where it acts as a tumor suppressor but can also promote tumor progression if cancer cells become resistant to its effects. In cancer TRAIL’s interaction with proteins like FLIP can alter the apoptotic potential of the cells. In autoimmune diseases TRAIL's dysregulation can contribute to tissue damage due to increased immune activity highlighting its complex role in maintaining immune balance.
