Abstract:
Gasdermin D (GSDMD) is a protein that has gained significant attention in recent years due to its crucial role in inflammatory cell death, particularly pyroptosis. Pyroptosis is a highly inflammatory form of programmed cell death that is triggered by various microbial infections and sterile inflammatory stimuli. GSDMD acts as an executioner molecule in this process, leading to the release of pro-inflammatory cytokines and amplifying the immune response. Here, we present a higher resolution, significantly improved apo crystal structure of the deposited mouse structure model that will be beneficial for structure-based drug-design approaches towards this important pharmacological target.
Insights
Gasdermin D (GSDMD), a key protein in inflammatory cell death, has a new high-resolution crystal structure. This improved structure aids in developing drugs targeting GSDMD for inflammatory diseases.
Area of Science:
- Biochemistry

Background:
- Gasdermin D (GSDMD) is a critical protein mediating pyroptosis, a pro-inflammatory programmed cell death pathway.
- Pyroptosis is activated by infections and sterile inflammation, releasing inflammatory cytokines.
- GSDMD acts as the executioner molecule, driving membrane pore formation and cytokine release.
Purpose of the Study:
- To present a higher resolution apo crystal structure of mouse Gasdermin D.
- To provide an improved structural model for GSDMD.
