Targeted Reduction of PTBP1 Reverses Cognitive Impairment in a Mouse Model of Alzheimer's Disease

Many of the more sophisticated forms of medicine, including gene therapies and immunotherapies, are challenging to deliver to the brain. At the very least there are far fewer practical options for delivery, and it is possible that none of that that exist fit a given desired use case.

At the very least there are far fewer practical options for delivery, and it is possible that none of that that exist fit a given desired use case.

While direct injection into the brain or into reservoirs of cerebrospinal fluid can be achieved, they are sufficiently invasive and challenging to rule out commonplace use.

The useful part

Many of the more sophisticated forms of medicine, including gene therapies and immunotherapies, are challenging to deliver to the brain. At the very least there are far fewer practical options for delivery, and it is possible that none of that that exist fit a given desired use case. While direct injection into the brain or into reservoirs of cerebrospinal fluid can be achieved, they are sufficiently invasive and challenging to rule out commonplace use.

How it works

  • The brain is made up of many different cell types, and more sophisticated approaches will want specificity to regions or cell types.
