How TRPM4 and TRPM5 cell channels affect blood flow, taste, and blood sugar
Structural and Functional Studies of the TRPM4 and TRPM5 Channels
This project looks at how two tiny cell channels, TRPM4 and TRPM5, work and how that could help people with stroke, certain heart rhythm problems, or type 2 diabetes.

What this research studies
Researchers use high-resolution imaging (cryo-EM), lab biochemistry, and cell experiments to see the channels' shapes and how they open or close. They test how genetic changes and factors like calcium and temperature change channel behavior. The team compares TRPM4 and TRPM5 because they act differently in blood vessel muscle, taste cells, and pancreatic beta cells. Findings will be used to guide searches for drugs or tests that correct channel problems linked to stroke, Brugada syndrome, or diabetes.
Who could benefit from this research
Good fit: People with a history of stroke, Brugada syndrome, unexplained cerebral blood-flow issues, or type 2 diabetes — and those willing to provide blood or tissue samples — would be the most relevant candidates to contribute to or benefit from this work.
Not a fit: Patients seeking an immediate treatment benefit or those with conditions unrelated to TRPM4/TRPM5 are unlikely to see direct clinical benefit from this basic lab research.
Why it matters
Potential benefit: If successful, this work could point to new medicines or tests that prevent or treat stroke, certain abnormal heart rhythms, and aspects of type 2 diabetes.
How similar studies have performed: Other teams, including this group, have already solved cryo-EM structures of these channels, so the structural approach is established but clinical translation is still early.
