Brain–immune interactions in 22q11.2 deletion syndrome

Role of the brain-immune axis in neuropsychiatric disease

NIH-funded research University of Pennsylvania · NIH-11233243

What this research studies

From a patient perspective, researchers are using a mouse model that carries the same 22q11.2 genetic deletion seen in people to study how the blood-brain barrier and immune molecules like IL-6 and IL-1β affect the brain and behavior. They will mimic an environmental “second hit” to see how genetics plus outside stressors change brain-immune communication and behavior. Laboratory tests of brain vasculature, immune signaling, and behavior in the model will be combined with knowledge about the human 22q11.2 condition to link findings back to patients. The goal is to pinpoint mechanisms that could be targeted to prevent or lessen psychiatric symptoms associated with 22q11.2DS.

Who could benefit from this research

Good fit: People diagnosed with 22q11.2 deletion syndrome—particularly adolescents and adults concerned about emerging psychiatric symptoms—would be the most directly relevant group for this research.

Not a fit: People without the 22q11.2 deletion or whose psychiatric symptoms have no immune or blood-brain barrier component may not directly benefit from the findings.

Why it matters

Potential benefit: If successful, this work could point to immune-based treatments or strategies to protect the blood-brain barrier that might prevent or reduce psychiatric symptoms in people with 22q11.2 deletion syndrome.

How similar studies have performed: Other research has linked immune molecules and blood-brain barrier problems to autism and schizophrenia and prior work by this group showed BBB compromise in 22q11.2 models, but translating these findings into treatments is still an emerging area.
