Summary
Researchers engineered yeast to target fibronectin in inflamed intestines, releasing anti-TNF nanobodies to reduce colorectal cancer growth in mice.
Area of Science:
- Microbiology and Immunology
- Gastroenterology
- Oncology
Background:
- Inflammation is a key driver of colorectal adenocarcinoma.
- Targeting specific molecular markers like fibronectin in inflamed tissue offers a novel therapeutic strategy.
- Current treatments for inflammation-driven colorectal cancer have limitations.
Discussion:
- Bioengineered Saccharomyces boulardii was designed to home in on exposed fibronectin in inflamed intestinal tissue.
- The engineered yeast releases anti-TNF nanobodies to combat inflammation.
- This approach aims to mitigate inflammation-driven tumorigenesis.
Key Insights:
- Successful development of a targeted yeast-based delivery system for therapeutic agents.
- Demonstrated potential of anti-TNF nanobodies delivered by yeast to reduce inflammation.
- Proof-of-concept in a mouse model for treating colorectal adenocarcinoma.
Outlook:
- Further research may explore optimizing yeast delivery and nanobody efficacy.
- Potential for broader applications in treating inflammatory bowel diseases and other cancers.
- Clinical translation could offer a new therapeutic avenue for colorectal cancer.

01:28Yeast Signaling
14.8K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
