​Jaclyn Schwarz conducts research on how activation of the immune system early in life, or even before birth, influences the brain and behavior later.

Jaclyn Schwarz, assistant professor of psychological and brain sciences at the University of Delaware, has been named the 2017 Neuroscientist of the Year by the Delaware Chapter of the Society for Neuroscience (SfN).

The award was presented at the annual Delaware Neuroscience Symposium and Poster Session in December. The symposium, sponsored by the Delaware Center for Neuroscience Research and the Delaware chapter of SfN, also featured 48 poster presentations by graduate students, undergraduates and postdoctoral researchers from throughout the state.

Schwarz conducts research on how activation of the immune system—the body’s defense against infection—early in life, or even before birth, influences the brain and behavior throughout the lifespan. Among the disorders that might be linked to an early exposure to infection are autism, which is generally diagnosed in early childhood, and schizophrenia, often diagnosed in late adolescence.

“There is a strong link between early-life immune activation and later problems,” Schwarz said. “The question is: Why? How does this happen? Immune activation is supposed to be good for us; it protects us from disease. But somehow, in some contexts, it’s harmful.”

For example, she said, previous research has established that if a pregnant woman gets influenza in her second or third trimester, her child has an increased risk of mental health problems later in life. But, of course, many children whose mothers were exposed to the flu while pregnant never develop such problems, so Schwarz theorizes that the exposure to infection might be just the first factor leading to later difficulties.

“We call the early immune activation a ‘priming,’ but it can’t be the only factor,” she said. “Somehow, later in life for some of these children, something derails the normal trajectory of development.”

Schwarz’s lab currently has three active research projects. In one, her team is studying early-life immune activation to learn if males are more vulnerable than females to the effects, including learning disabilities, which are more prevalent in boys than girls.

She is also exploring if the changes that occur in a woman’s immune system during pregnancy can affect the immune cells in her own brain and possibly increase the risk of postpartum depression.

Her third research project is investigating the impact of the Zika virus in a pregnant woman on the brain development of her fetus.

“I see all three of these projects as interconnected,” Schwarz said. “The immune system is the common factor.”
