Identifying how pertussis toxin interacts with cell surfaces

Discovery of pertussis toxin receptors

['FUNDING_R21'] · UT SOUTHWESTERN MEDICAL CENTER · NIH-11093550

This study is looking at how a toxin from the whooping cough bacteria interacts with different types of cells in the body, especially those involved in the immune response and breathing, to help find ways to better treat and understand the disease.

What this research studies

This research investigates how the pertussis toxin, produced by Bordetella pertussis, binds to and affects different cell types, particularly lymphocytes and respiratory epithelial cells. Using advanced techniques like CRISPR/Cas9 genome-wide knockout screening, the study aims to identify specific genes and glycan structures that influence the toxin's binding and internalization. By understanding these interactions, researchers hope to uncover the mechanisms behind the severity of whooping cough and potentially develop targeted therapies.

Who could benefit from this research

Good fit: Ideal candidates for this research are children under 11 years old who are at risk for or have been diagnosed with pertussis.

Not a fit: Patients who are older than 11 years or those who have not been exposed to Bordetella pertussis may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments for whooping cough and better understanding of how to prevent severe symptoms in affected children.

How similar studies have performed: While the specific approach of this research is novel, similar studies have successfully identified toxin interactions in other bacterial infections.
