"Aberrant synapse formation is important in the pathogenesis of schizophrenia and autism," says Osaka University Professor Toshihide Yamashita, one of the authors of the study. "Microglia contribute to the structure and function of synapse connectivities." Microglia are the only cells in the brain that express the receptor CX3CR1. Mutations in this receptor are known to affect synapse connectivity and cause abnormal social behavior in mice. They have also been associated with neuroinflammatory diseases such as multiple sclerosis, but no study has shown a role in neurodevelopment disorders. Working with this hypothesis, the researchers conducted a statistical analysis of the CX3CR1 gene in over 7000 schizophrenia and autism patients and healthy subjects, finding one mutant candidate, a single amino acid switch from alanine to threonine, as a candidate marker for prediction. "Rare variants alter gene function but occur at low frequency in a population. Th...

Elevated DNA double-strand breaks in Pol-beta-deficient neural progenitors. Credit score: Osaka College DNA is the pc code that applications each occasion within the physique. Regardless of the significance of DNA constancy, because the physique develops, cells develop and replicate, DNA is consistently turned over. This repeated course of can compromise the DNA, which is why the physique has many DNA restore machineries. Utilizing mice, Osaka College scientists report a defect in a single kind of equipment, DNA polymerase β (Polβ), causes underdevelopment of the mind's cortices and axonal community. The findings might assist clarify cortical improvement issues, comparable to autism and microcephaly. "Polβ is chargeable for repairing DNA base injury within the mind. As a result of many neurological issues are related to de novo ...
