A recently published collaboration between academic researchers and pharmaceutical companies was successful at detecting huntingtin in tears. The scientists were looking for a new, easy way to track Huntington’s disease (HD). If you don’t mind shedding a tear or two, they found it!
Biomarkers - biological metrics in tune with disease progression
Tracking disease progression is not only medically important to ensure patients are living a healthy life, but it’s also important for developing medicines for diseases like HD. Biological metrics that are in tune with disease progression are called biomarkers. There are different kinds of biomarkers, from images of organs, to tests of metabolism, to measurements made in body fluids.
Biomarkers are tools that researchers can use to assess how well a potential medicine is working. If a drug slows or stops the progression of a disease according to one or more biomarkers, it could mean that drug is working!
