Study finds new insight on maternal infections, neurodevelopmental disorders
Researchers have found that the immune responses of a female mouse
before pregnancy can predict how likely her offspring are to have
behavioural deficits if the immune system is activated during pregnancy.
The study results could help resolve what role serious infections
during pregnancy play in the later development of conditions such as
autism and schizophrenia in offspring. Both genetics and a variety of
environmental risk factors are thought to play a role in mental illness,
said Professor Kim McAllister, director of the Center for Neuroscience
and senior author on the paper. Most pregnancies are resilient, she
said. Although the risk from maternal immune activation is low, it could
provide a way into the underlying problems that lead to schizophrenia
or autism.
