Zika Could Affect Adult Brains, Says New Study
New research suggests the Zika virus may damage some cells in adult brains.
Until now, scientists mainly worried about Zika's effects on the brains of babies whose mothers were infected with the virus during pregnancy.
The Rockefeller University and La Jolla Institute for Allergy and Immunology carried out the new research. The findings were published last week in the Cell Stem Cell journal.
The research suggests the Zika virus could infect some kinds of adult cells. These cells are considered important to learning and memory.
"This is the first study looking at the effect of Zika infection on the adult brain," says Joseph Gleeson. He is a professor at Rockefeller University and head of the Laboratory of Pediatric Brain Disease. Gleeson says, "Based on our findings, getting infected with Zika as an adult may not be as innocuous as people think."
By innocuous, Gleeson means not seeming to have a harmful effect.
In their study, the researchers examined cells in mice.
According to the U.S. Centers for Disease Control and Prevention, or CDC, the Zika virus is spread mostly by a bite from an infected mosquito.
Zika can be passed from a pregnant woman to her fetus, the CDC said. It said infection during pregnancy can cause certain birth defects.
Gleeson, the Rockefeller University professor, says most adults seem able to overcome the harmful effects of Zika. But, he said people with compromised immune systems could face problems.
An immune system protects a person from disease and infection.
The major worry, Gleeson says, is that Zika could affect long-term memory in some adults. However, he adds that "a lot more research" is needed.
Sujan Shresta is a professor at the La Jolla Institute of Allergy and Immunology.
She notes that most adults infected with Zika do not show any health problems.
Shresta said the effects on adult brain cells may not be as clear as the effects on babies infected with the Zika virus.
Shresta said, thanks to the new research, health officials now know "what to look for."

洛克菲勒大学携手过敏免疫学拉霍亚研究所进行了这一研究 。上周，《细胞·干细胞》杂志发表了该研究结果 。
该研究表明，寨卡病毒会影响成人部分细胞 。这些细胞在习得和记忆方面有重要作用 。
约瑟夫·格里森（Joseph Gleeson）称：“这是寨卡病毒影响成人大脑的首次研究” 。格里森是洛克菲勒大学的教授和小儿脑部疾病实验机构的首席专家 。格里森表示：“研究发现，成人感染寨卡病毒并非如人们想象的那样无害 。”
美国疾病预防控制中心表示，寨卡病毒可通过孕妇传染给胎儿 。女性在怀孕期间感染病毒可能造成胎儿某些先天性缺陷 。
洛克菲勒大学的教授格里森表示，多数成年人似乎能够克服寨卡病毒的有害性 。但免疫系统受损的人会因此面临很多问题 。
格里森称，目前主要担心的是寨卡可能影响部分成年人的长期记忆 。不过他补充说，仍需要“更多的研究”进行核实 。
