DALLAS - Dec. 16, 2020 - A team led by UT Southwestern researchers has identified a key gene necessary for cells to consume and destroy viruses. The findings, reported online today in

Scientists have long known that cells use a process called autophagy to rid themselves of unwanted material. Autophagy, which translates as self-eating, involves isolating cellular garbage in double-layered vesicles called autophagosomes, which are then fused with single-layered vesicles known as lysosomes to degrade the materials inside and re ....

 E-Mail
A deficiency in Vitamin D on the mother s side could explain why Autism spectrum disorder is three times more common in boys, say researchers from The University of Queensland.
In their latest study, Professor Darryl Eyles and Dr Asad Ali from UQ s Queensland Brain Institute found vitamin D deficiency during pregnancy caused an increase in testosterone in the developing brain of male rats.
The biological cause of Autism spectrum disorder (ASD) is unknown but we have shown that one of the many risk factors low vitamin D in mothers causes an increase in testosterone in the brain of the male foetuses, as well as the maternal blood and amniotic fluid, Professor Eyles said. ....
