Genetically engineered mosquitoes resist spreading any form of dengue
Recover from dengue once, and you’re not necessarily free and clear. The mosquito-borne disease marked by fever, rash, and debilitating pain results from any of four genetically distinct versions of the dengue virus. Previously infected people who get hit with a second of these “serotypes” can face more severe, even life-threatening symptoms. Now, by endowing a line of mosquitoes with an antibody against the virus, researchers have for the first time made insects that—at least in lab tests—appear unable to spread any form of the disease.
Meet the pioneering scientists transforming medicine for millions of people
Everybody gets sick now and then. But if it weren’t for antibodies – the weapons that help our immune systems fight viruses, bacteria or even cancer cells – some illnesses would be much more frequent and potentially lethal.
Highly Cited Researchers 2019

Towards a universal flu vaccine
Flu shots can be hard to sell to the public. Even a run-of-the-mill influenza infection can be debilitating to otherwise healthy people, and lethal to those who are elderly or frail, so vaccinations are important. The problem is that flu vaccines deliver inconsistent performance. “In a good season, we’re up to 60% effectiveness, but in bad, mismatched years it can be as low as 10% or 20%,” says Barney Graham, deputy director of the Vaccine Research Center at the US National Institute of Allergy and Infectious Diseases (NIAID) in Bethesda, Maryland.
Partnership to help bring Zika virus therapy to clinic
Researchers at Vanderbilt University Medical Center are partnering with the Dutch biopharmaceutical firm Batavia Biosciences and Nashville-based IDBiologics to bring to the clinic a highly potent Zika virus neutralizing antibody they isolated three years ago. The mosquito-borne Zika virus is believed to cause microcephaly, unusually small heads, and other congenital malformations in children born to infected women. Currently there is no way to prevent Zika virus infection or its aftermath.
Laura Powell receives scholarship for the Keystone conference
Laura Powell has been awarded a Keystone Symposia Future of Science Fund scholarship to attend the upcoming meeting on Positive-Strand RNA Viruses, Jun 9 - Jun 13, 2019, in INEC, Killarney Convention Centre in Killarney, Co. Kerry. Congrats Laura!
Can synthetic biology help Vanderbilt University Medical Center researchers develop therapeutic antibodies in only 90 days?
It seems as though every year there is another story of a virus rampaging through Africa, Asia, or even the Americas. And each time another Ebola outbreak occurs or the flu virus mutates in surprising ways, the conversation about global pandemic preparedness is rekindled. Borders are closed. Flights and cruise ships are cancelled. Images of quarantine tents and healthcare workers in space-like suits fill the news outlets.
