Molecular probes for monitoring pyroptosis: design, imaging and theranostic application

Area of Science:

• Oncology
• Cell Biology
• Immunology

Background:

• Pyroptosis is a distinct form of programmed cell death characterized by gasdermin D (GSDMD) pore formation.
• This cell death pathway is increasingly recognized for its role in tumor progression and its potential as a therapeutic target.
• Current understanding of pyroptosis mechanisms, especially in real-time, is limited by the lack of advanced imaging techniques.

Purpose of the Study:

• To review current non-invasive molecular probes for detecting pyroptosis.
• To highlight the potential of these imaging strategies in understanding pyroptosis in inflammatory diseases and tumors.
• To explore how these techniques can advance personalized antitumor therapies.

Main Methods:

• Discussion of genetic reporters for pyroptosis detection.
• Review of nanomaterial-based probes for non-invasive pyroptosis imaging.
• Analysis of current literature on live cell imaging techniques for programmed cell death.

Main Results:

• Non-invasive molecular probes, including genetic reporters and nanomaterials, offer new ways to visualize pyroptosis.
• These imaging techniques can provide real-time insights into pyroptosis mechanisms.
• The development of such probes is essential for advancing diagnostic and therapeutic strategies.

Conclusions:

• Non-invasive imaging of pyroptosis is critical for understanding its role in diseases like cancer.
• Advanced imaging probes can facilitate the development of targeted immunotherapies and personalized cancer treatments.
• Further research into pyroptosis imaging will enhance prognostication and treatment efficacy for inflammatory diseases and tumors.
