NIH-funded research teams have created a versatile set of gene delivery systems that can reach different neural cell types in the human brain and spinal cord with exceptional accuracy. These delivery systems are a significant step toward precise gene therapy that could safely control errant brain activity. Current therapies for brain disorders mostly target symptoms.

NIH researchers have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer.
