Cry your eyes out: detecting huntingtin in tears

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 […]

The director’s cut: how CAG repeats change the editing of genetic messages

Long repetitive sequences of C-A-G letters in the DNA code are associated with at least 12 genetic diseases, including Huntington’s disease (HD). A group of scientists in Massachusetts, USA, have recently developed a new genetic strategy to study how CAG repeats can lead to harmful proteins being made in cells, causing cells to become unhealthy. […]

Making babies: having a family, the HD way

For people at risk of Huntington’s disease, having a baby who might inherit HD can make decisions around planning a family extremely difficult. This article explains the options available, and how modern reproductive science can make a difference right now to families touched by HD. Content warning This article describes issues of fertility, tough choices, […]

Understanding expansions at the single cell level

In two recent studies, researchers looked at how different parts of the brain are affected by CAG expansions in Huntington’s disease (HD) at the level of individual brain cells. The scientists looked at post-mortem brains from people with and without HD to track molecular changes in different brain regions called the cortex and striatum. These […]
