When necrotic cells expose phosphatidylserine on their outer surfaces, and when phagocytes detect it, the phagocytes ingest and destroy the dying cells.
Biological sequencing of the fusion peptides of SARS-CoV and SARS-CoV-2 found them to be a 93% match. Calcium ions interacting with the fusion peptide alters the peptide's structure, and how it interacts with membranes to promote infection. The findings provide a potential target for antiviral development to treat coronavirus.
A process which helps maintain calcium levels in cells may also play a role in maintaining dopamine levels, researchers report.
Researchers identify a calcium dependent mechanism for neuronal information storage.
Researchers were able to visualize neuronal activity, thanks to a new protein which fluoresces brightly each time it senses calcium.
