Zika virus, which can infect neural stem cells kill
#Cosmoread: Zika virus and infect a type of brain cell that is important for brain development, a new study conducted in human cells growing in lab dishes can kill by.
Zika virus can cause the condition in children, although the results do not prove that called microcephaly, finding where and how the virus can cause damage in the brain, the researchers said. children born with microcephaly undeveloped brain and severe, lifelong developmental disabilities may face.
However, researchers said more studies are needed. “This is a first step, and there is a lot more that needs to be done,” said study co-author Hongjun Song, Johns Hopkins University School of Medicine in Baltimore, a professor of neurology at, said in a statement.
The researchers showed that Zika virus can infect brain cells in lab dishes; However, researchers still a developing fetus if the same thing happens to the virus-infected cells in the know, asked to sing.
Researchers to study human embryonic stem cells in the human brain cortex that give rise to similar cells used were engineered to produce. Scientists also a real-life scenarios in which a human virus before infecting a mosquito carries the virus to replicate in mosquitoes grew Zika.
Then, the researchers applied the Zika virus brain cells grown in the lab and found that only three days and virus-infected cells and spread through a plate. The virus killed cells or disrupted their development.
It is not clear in any way to the cells, the researchers do not know what that means or how Zika virus is cleared from cells defend themselves against viruses or not, the researchers said.
Zika virus infection in the fetus that shows something about the case reports in some brain regions appear to be developing normally, most of the brain’s cortex that are missing it, study co-author Guo Li Ming , a professor of neuroscience at Johns Hopkins University school of Medicine structures, said in a statement. “So our work is a very important question that emerges is whether the Zika virus specifically targets nerve [cells] is responsible for generating most cortex.”
