Does the COVID-19 cytokine storm exist?

Research may have an impact on the chances of success of a specific treatment RADBOUD UNIVERSITY MEDICAL CENTER Inflammatory proteins, also known as cytokines, play a crucial role in the immune response. If this immune response is too strong, a phenomenon known as “cytokine storm”, it can cause harm to the patient. It has been...

‘Hotspots’ of a SARS-CoV-2 infection in the human body

by German Center for Neurodegenerative Diseases An infection with the coronavirus SARS-CoV-2 can affect multiple organs. With this in mind, researchers of the German Center for Neurodegenerative Diseases (DZNE) and Cornell University in the US have investigated cellular factors that could be significant for an infection. To this end, they analyzed the activity of 28...
