Targeting H. pylori's sugar coating to find better treatments
Deciphering Helicobacter pylori's glycocode: uncovering and harnessing drug targets
['FUNDING_R15'] · BOWDOIN COLLEGE · NIH-11288895
Researchers are testing chemical tools that map and block the sugar coatings H. pylori uses to stick to and survive in the stomach to help people with H. pylori infections.

What this research studies
This lab uses specially designed sugar molecules and chemical probes to label and interfere with the sugars on the surface of the stomach bacterium H. pylori. By tagging these sugars they can see how H. pylori sticks to stomach cells and which bacterial or human proteins are involved. They will also test molecules that block sugar production or create permanent links to nearby proteins to disrupt bacterial survival. The work is done in lab dishes and with bacterial samples and could guide future, more targeted antibiotic strategies.
Who could benefit from this research
Good fit: Ideal candidates would be people with confirmed H. pylori infection who are willing to provide bacterial or stomach biopsy samples for research.
Not a fit: People without H. pylori infection or those needing immediate clinical treatment are unlikely to receive direct benefit from this lab-focused work.
Why it matters
Potential benefit: Could lead to antibiotics that specifically target H. pylori while sparing beneficial gut bacteria, reducing side effects and treatment failure.
How similar studies have performed: Related preclinical work using metabolic labeling of bacterial sugars has revealed surface structures and candidate targets, but converting these findings into human treatments is still unproven.
