Lowering FKBP51 to help people with PTSD

Controlling FKBP51 for the treatment of PTSD

NIH-funded research James a. Haley VA Medical Center · NIH-11213855

This project looks at whether reducing a brain protein called FKBP51 can improve stress responses and symptoms in people with PTSD.

What this research studies

Researchers are developing antisense oligonucleotide drugs designed to lower levels of FKBP51, a protein linked to stress responses in the brain. They will test these approaches in mouse models that either lack or overproduce FKBP51 and expose them to PTSD-like stress to see if reducing the protein changes behavior and brain chemistry. The team will measure trauma-related behaviors and molecular changes in the brain to judge whether FKBP51 is a promising target. The goal is to validate this approach so it could be translated into new treatments for PTSD in people.

Who could benefit from this research

Good fit: People living with PTSD—particularly Veterans and others who carry the FKBP5 rs1360780 genetic variant linked to higher FKBP51—would be the most relevant candidates for therapies developed from this research.

Not a fit: People without PTSD or whose symptoms are driven by factors unrelated to FKBP51 overexpression are unlikely to benefit from FKBP51-targeted treatments.

Why it matters

Potential benefit: If successful, this work could lead to new therapies that reduce PTSD symptoms by targeting FKBP51 in the brain.

How similar studies have performed: Antisense drugs have worked for some neurological disorders, but targeting FKBP51 for PTSD is largely experimental with promising preclinical evidence.
