Researchers generate a transcriptomic map of the COVID brain

COVID-19 is known to be associated with multiple changes in gene expression, but many of these are also seen in chronic brain conditions as well as in some abnormal mental conditions. A recent study published on the preprint server bioRxiv in October 2020 uncovers the molecular basis of this association.

NRP-1 receptor potentiates SARS-CoV-2 infectivity

The COVID-19 pandemic is still actively spreading in many parts of the world, causing redoubled efforts to develop antivirals and vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A recent study explores the role of a second type of cell surface receptor, called neuropilin, in the virus's entry into the host cell and its subsequent replication.
