Cardiovascular Drug Discovery Lab (Medical and Hygienic Pharmaceutical Sciences)
Machine-translated · View original
A lab that develops drugs to treat diseases, using the functions of blood vessels as a clue.

AboutAbout the lab
From vascular research to groundbreaking new drugs
The Cardiovascular Drug Discovery Lab investigates the mechanisms of vascular function and applies them to the development of drugs to treat diseases.
Blood vessels are not only passageways that carry oxygen and nutrients through the blood, but also control the movement of substances and cells between the blood and organs by changing their permeability.
The lab works on treating inflammatory diseases and infections, delivering drugs to the brain, and restoring fibrotic organs.
Key terms
- Vascular permeability
- The degree to which substances and cells pass through the vessel wall between the blood and organs.
- Blood-brain barrier
- The function by which blood vessels in the brain keep permeability extremely low, protecting the brain from the entry of foreign substances.
- Fibrosis
- A condition in which organs are repeatedly damaged and fibroblasts increase, lowering organ function.

ResearchResearch themes
The lab aims to propose unprecedented treatments for diseases, with new ideas based on the results of vascular research. It investigates how vascular function differs and changes from organ to organ, and links this to the development of molecules that control it.
*Illustrative imageDeveloping drugs that suppress vascular permeability
In inflammatory diseases and infections, the disease state arises when vascular permeability becomes excessively high. By understanding the mechanisms that regulate permeability and developing molecules that control it, the lab hopes to propose treatments based on a new strategy.
*Illustrative imageTechnology to deliver drugs to the brain
Blood vessels in the brain have extremely low permeability and, as the blood-brain barrier, protect the brain from the entry of foreign substances. However, this also hinders drug delivery, so the lab develops technologies that transiently control this function to promote drug delivery to the brain.
*Illustrative imageRestoring fibrotic organs
When organs are repeatedly damaged by inflammation or other causes, they become fibrotic and almost never heal on their own. Using blood vessels, the lab works on developing curative treatments that restore fibrotic organs to their original state.
