Zika virus could cause microcephaly by hijacking human immune molecule: Fetal brain model provides first clues about how Zika virus blunts brain development blocking mechanism reduces cell damage
The U.S. Cdc and Prevention lately figured that Zika virus infection in women that are pregnant can stunt neonatal brain development, resulting in babies born with abnormally small heads, an ailment referred to as microcephaly. Now, the very first time, researchers at College of California North Park Med school have determined one of the ways Zika infection can harm developing cognitive abilities. The research, printed May 6, 2016 in Cell Stem Cell , also implies that inhibiting this mechanism reduces brain cell damage, meaning in a new therapeutic method of mitigating the results of prenatal Zika virus infection.
Utilizing a 3D, stem cell-based type of an initial-trimester mind, they learned that Zika activates TLR3, a molecule human cells normally use to protect against invading infections. Consequently, hyper-activated TLR3 turns off genes that stem cells have to specialize into cognitive abilities and activates genes that trigger cell suicide. Once the researchers inhibited TLR3, brain cell damage was reduced within this organoid model.
"Everyone has a natural defense mechanisms that evolved particularly to battle off infections, but here herpes turns that exact same defense mechanism against us," stated senior author Tariq Rana, PhD, professor of pediatrics at UC North Park Med school. "By activating TLR3, the Zika virus blocks genes that tell stem cells to build up in to the parts from the brain. The good thing is we have TLR3 inhibitors that may preclude this from happening."
