How sex affects immune cells' role in adolescent brain wiring
Sex differences in microglia-neuron-circuit interactions in adolescence
Researchers are looking at how male and female adolescent brain immune cells called microglia help shape prefrontal brain connections, with implications for teens at risk for psychiatric conditions.

What this research studies
This project uses advanced imaging and targeted stimulation in awake mice to watch microglia and neurons in the prefrontal cortex during adolescence. Scientists will use 3-D two-photon microscopy to image fine microglial processes and single-neuron optogenetics to activate cells while observing how nearby microglia move and interact. They will compare males and females across the adolescent period to find sex differences in how microglia influence circuit synchrony and synaptic connections. The goal is to link these cellular interactions to vulnerabilities for psychiatric disorders that often start in the teen years.
Who could benefit from this research
Good fit: Adolescents or young adults (roughly ages 12–25) with early psychiatric symptoms or a family history of disorders like schizophrenia would be most relevant.
Not a fit: People whose conditions are unrelated to adolescent brain development or non-psychiatric medical problems are unlikely to receive direct benefit from this specific research.
Why it matters
Potential benefit: If successful, this work could reveal sex-specific mechanisms behind adolescent-onset psychiatric disorders and suggest new targets for prevention or treatment.
How similar studies have performed: Prior animal studies have shown microglia can shape synapses and that sex differences exist, but combining live 3-D imaging and optogenetics in adolescent prefrontal circuits is a newer, more detailed approach.
