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...
Why so many COVID-19 patients get blood clots (thrombosis) remains uncertain. But scientists at Uppsala University and the University Hospital have now identified a mechanism they believe to be implicated. A particular protein triggers a part of our immune system that can boost the blood’s tendency to coagulate and form clots. The study is now...
