Study of glycosylation on SARS-CoV-2 spike protein

The first intimation of the current COVID-19 crisis came with the news of severe pneumonic illness caused by an unknown agent in a Chinese city called Wuhan, issued on the last day of 2019. Following this, researchers found the cause to be a novel coronavirus, closely related to the earlier SARS virus, now called severe acute respiratory syndrome coronavirus 2.

New approach holds incredible potential for developing new therapeutics

Nearly every drug that is, or has ever been, used was derived from nature -- harnessing compounds created by organisms over eons to fight diseases. But decades ago, biochemists postulated that it might be possible to design a new drug from scratch by linking up amino acids in precise ways.

Researchers track brain receptor as it transmits or inhibits neural signals

For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals. Critical for brain development and function, the receptor converts chemical messages between cells into electrical signals within a neuron.
