All physiological functions in humans are orchestrated by cell surface receptors and their intracellular signaling effects. Cell signaling typically consists of 5 components: stimulus, receptor, transducer, messenger, and effector. These components are modularly linked to each other to ensure that extracellular cues are relayed flawlessly... click to read more

Most cells in our body don’t move: they stay put, forming dense tissues. But one population of cells moves continually, and we would not survive without them. These immune cells arrive at any spot in our body where damage or infection arises. Immune cells... click to read more

Over the last two years, multiple risk mitigation strategies have been deployed to reduce the rate of spread of SARS-CoV-2 (the virus that causes COVID-19) in congregate settings, including schools and early childcare programs. Layered strategies include: screening for COVID-19 related symptoms and/or SARS-CoV-2 testing... click to read more

While serological tests are not intended to diagnose an acute SARS-CoV-2 (COVID-19) infection, they can indicate the presence of antibodies generated from previous viral exposure or vaccination. Several diagnostic kits to assess the presence of SARS-CoV-2 antibodies are available on the market, all using blood/serum... click to read more

When the first protein structure was solved in 1958, scientists knew they had broken into a new frontier of biology. They felt that a protein’s structure would reveal all the secrets of its function, and almost 70 years down the line, over 150,000 structures have... click to read more
