Gsdmd Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
GSDMD (Gasdermin D) is a gene encoding a key executor of pyroptotic cell death. The GSDMD protein forms pores in the plasma membrane, leading to cell swelling and release of inflammatory contents. This process is mediated by caspase-1, caspase-4/5 (human), and caspase-11 (mouse). Gasdermin D has emerged as a critical link between inflammasome activation and neurodegenerative cell death in AD, PD, and ALS. [@liu2020]
Gene Information
Molecular Function
GSDMD encodes a gasdermin family protein critical for pyroptosis:
Pyroptosis Execution: Full-length GSDMD is cleaved by caspases to release the N-terminal domain
Pore Formation: N-terminal domain oligomerizes and inserts into membranes, forming pores (10-20 nm)
Inflammatory Release: Pores allow release of IL-1β, IL-18, and alarmins
Alternative Activation: Can be activated by caspase-3 in certain contexts (caspase-7 dependent)
Disease Associations
Alzheimer's Disease
GSDMD-mediated pyroptosis contributes to neuronal loss in AD
Amyloid-β activates the [NLRP3](/entities/nlrp3-inflammasome) inflammasome, leading to GSDMD cleavage
