Now, to enable widespread gene delivery throughout the central and peripheral nervous systems, Caltech researchers have developed two new variants of a vector based on an adeno - associated virus (AAV): one that can efficiently ferry genetic cargo past the blood - brain barrier; and another that is efficiently picked up by peripheral neurons residing outside the brain and spinal cord, such as those that sense pain and regulate heart rate, respiration, and digestion.

The vectors are customizable and could potentially be used as part of a gene therapy to treat neurodegenerative disorders that affect the entire central nervous system, such as Huntington's disease, or to help map or modulate neuronal circuits and understand how they change during disease.
