Scientific Director of the Leiden Academic Centre for Drug Research (LACDR) Hubertus Irth: ‘We test substances and look for new concepts for treating disease.’

There have been indications for decades that there is a link between increased iron levels in the brain and Alzheimer’s disease. Leiden physicists find this connection as well, thereby now making a distinction between different forms of iron. They identify specific iron forms that increase in Alzheimer’s…

Biophysicist Alireza Mashaghi and his collaborators are taking up the fight against muscular dystrophy: genetic disorders that cause muscle weakness.

Visualization of biomolecules in living cells by tagging with gold nanoparticles.

Atherosclerosis is a progressive disease resulting in the formation of an arterial plaque. Despite lipid lowering, recurrent cardiovascular events remain a risk. While atherosclerosis is primarily lipid-driven, the immune system plays a critical role in the pathophysiology.

For medical research, researchers often recreate tissue in the lab. Organ-on-a-chip technology emulates organs, right down to the blood that flows through them, thus creating a realistic test model for drugs or research into disease processes. Researchers from the LUMC are coordinating an NWO Gravitation…

With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins. Drug development…
