Tunnel-building virus: How Zika transmits from mother to fetus

A team of researchers from Penn State and Baylor College of Medicine found that the Zika virus builds tiny tunnels, called tunneling nanotubes, to stealthily transport material needed to infect nearby cells, including in placental cells.

How does Zika virus replicate and transmit from mother to fetus?

In 2015, an outbreak of Zika virus, driven by a heavy rain season and subsequent boom in the virus’s host mosquito population, caused thousands of babies in Brazil to be born with severe birth defects.

Repurposing FDA-approved drugs may help combat COVID-19

Several FDA-approved drugs — including for type 2 diabetes, hepatitis C and HIV — significantly reduce the ability of the Delta variant of SARS-CoV-2 to replicate in human cells, according to new research led by scientists at Penn State. Specifically, the team found that these drugs inhibit certain viral enzymes, called proteases, that are essential for SARS-CoV-2 replication in infected human cells.

Fighting COVID with COVID

What if the COVID-19 virus could be used against itself? Researchers at Penn State have designed a proof-of-concept therapeutic that may be able to do just that. The team designed a synthetic defective SARS-CoV-2 virus that is innocuous but interferes with the real virus’ growth, potentially causing the extinction of both the disease-causing virus and the synthetic virus.
