Psychiatry Residents Present Innovative Research at the Third Annual Psychiatry Research Pathway Symposium
The Psychiatry Research Pathway (PRP) Symposium provides UPMC Western Psychiatric Hospital residents engaged in research the opportunity to present their work to an audience of fellow residents, faculty mentors, and other members of our career development community. This year’s program included a talk from seven residents on their current and/or future research, followed by questions and feedback. Program Director...
Department Researchers Find Higher Activity of the Immune-Regulating NF-κB Signaling Pathway in Schizophrenia
Schizophrenia is a devastating neurodevelopmental disorder, marked by changes in a person’s thinking, emotions, and behavior. A number of brain areas are affected in the illness, including a region called the prefrontal cortex that is important for cognitive control of behavior. A growing body of evidence suggests that the immune system is activated in the prefrontal cortex in schizophrenia, but it is unclear how...
