These two terms describe two different ways that viral nucleic acids and proteins are arranged in virus particles. The capsid (from the Latin capsa for box) is the protein shell surrounding the nucleic acid genome. Below are two different …
Intranasal administration with a single dose of a chimpanzee adenovirus-vectored SARS-CoV-2 vaccine induces potent immune responses.
A capsid-like protein derived from an ancient retrotransposon family may help regulate learning and memory.

HSV-1 virions capture the cellular motor protein kinesin from initially infected epithelial cells and ferry it to subsequently infected neuronal cells to deliver their genome into the nucleus of those cells.
It will be some time before a substantial fraction of the human population is immunized to prevent COVID-19. In the meantime, widespread use of face masks can have an impact on disease, a conclusion suggested by results of a trial carried out in Bangladesh. WHO would not recommend the use of face masks until June …
