Target intelligence / Profile preview

Death receptor 4 (DR4)

Target
DR4
Molecular classification
Receptor, Tumor necrosis factor (TNF) receptor superfamily
01

Overview

Death receptor 4 is a key mediator linking extracellular apoptotic signals from immune surveillance or therapeutic agents directly into programmed cell death machinery within susceptible target cells—most notably cancerous ones—making it an important focus for research into targeted therapies against malignancies.

Other names
TRAIL receptor 1 (TRAILR1)Tumor necrosis factor receptor superfamily member 10A (TNFRSF10A)
02

Mechanism of action

Agonistic antibodies bind to DR4, inducing receptor trimerization, recruitment of FADD and caspase-8, and subsequent activation of the caspase cascade leading to apoptosis.

Safety considerations

Limited efficacy of TRAIL-based therapies due to resistance mechanisms in tumors.Potential for off-target effects if not selective for cancer cells.Potential for inducing inflammatory cytokine secretion, leading to immunosuppression.
