Researchers determine role of NLRP1 protein in detecting the common cold virus

The role of a protein in detecting the common cold virus and kickstarting an immune response to fight infection has been uncovered by a team of scientists from Nanyang Technological University, Singapore (NTU Singapore), the Agency for Science, Technology and Research (A*STAR) and the National University of Singapore.

Previously uncharacterized protein regulates mitochondrial NAD transporter

For their growth, cells need various nutrients and vitamins. So-called solute carriers (SLC), proteins that can transport such substances across the boundaries of cellular membranes, play a central role in metabolism.

Vibrational motions of spike proteins correlate with infectivity, lethality of SARS-CoV-2 virus

When someone struggles to open a lock with a key that doesn't quite seem to work, sometimes jiggling the key a bit will help. Now, new research from MIT suggests that coronaviruses, including the one that causes Covid-19, may use a similar method to trick cells into letting the viruses inside.

MIT chemists determine molecular structure of SARS-CoV-2 protein

MIT chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein, called the envelope protein E, forms a cation-selective channel and plays a key role in the virus's ability to replicate itself and stimulate the host cell's inflammation response.

Researchers reveal identity of the last unknown protein of autophagy

Drs. Nobuo Noda (Director) and Kazuaki Matoba (Senior Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that Atg9, one of the proteins that function to mediate autophagy, has phospholipid-translocation activity (the lipid scramblase activity) between the two layers of the lipid bilayer and elucidated that the protein's activity brings about autophagosome membrane expansion.

Simple skin test can accurately identify Parkinson's disease

New research shows a simple skin test can accurately identify Parkinson's disease, demonstrating for the first time the feasibility of the method. Currently diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy, Parkinson's disease is commonly misdiagnosed early in the disease course, complicating clinical trials of potential treatments.

Vacuolar Tauopathy: New, rare genetic form of dementia discovered

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies. The study was published today in Science.
