Description
GSDMD (Gasdermin D) is a key executor of pyroptosis, a lytic form of programmed cell death. It is cleaved by inflammatory caspases (CASP1, CASP4, CASP5, CASP11) to release an N-terminal domain that forms membrane pores, leading to cell lysis and release of pro-inflammatory cytokines. GSDMD is critical for innate immune responses and is implicated in various inflammatory and infectious diseases.
Disease Associations
| Disease category | Pathophysiological mechanism | Genomic evidence |
|---|---|---|
| Sepsis | GSDMD-mediated pyroptosis contributes to excessive inflammation and organ damage in sepsis. | PMID: 28991256; 30318143 |
| Inflammatory bowel disease (IBD) | GSDMD activation in intestinal epithelial cells promotes inflammation and tissue injury. | PMID: 31435016 |
| Gout | GSDMD cleavage by caspase-1 in response to monosodium urate crystals drives IL-1β release and inflammation. | PMID: 29769723 |
| Alcoholic steatohepatitis | GSDMD-mediated pyroptosis in hepatocytes exacerbates liver inflammation and fibrosis. | PMID: 30318143 |
| Familial Mediterranean fever (FMF) | Mutations in MEFV lead to inflammasome activation and GSDMD-dependent pyroptosis, contributing to disease flares. | PMID: 29769723 |
| Cancer (various) | GSDMD expression can be tumor-suppressive or pro-tumorigenic depending on context; pyroptosis in tumor cells may enhance anti-tumor immunity. | PMID: 31435016 |

Mutation functional classification
Loss of Function (LOF)
Mutations that impair GSDMD cleavage or pore formation reduce pyroptosis, leading to defective immune responses and increased susceptibility to infections.
Gain of Function (GOF)
Mutations that enhance GSDMD activation or pore stability can cause excessive pyroptosis, contributing to inflammatory pathology.
Dominant Negative (DN)
Some missense mutations may produce a dominant-negative effect by interfering with wild-type GSDMD oligomerization.

Protein Summary
Gasdermin D (GSDMD) is a 53 kDa protein composed of an N-terminal pore-forming domain and a C-terminal autoinhibitory domain. Upon cleavage by inflammatory caspases, the N-terminal domain oligomerizes and inserts into the plasma membrane, forming 10-15 nm pores that disrupt ion homeostasis and induce cell lysis. This releases pro-inflammatory cytokines like IL-1β and IL-18, and DAMPs, amplifying immune responses. GSDMD is also involved in other processes such as NETosis and pyroptosis-induced inflammation.
