Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Study pinpoints an enzyme with a significant impact on SARS-CoV-2 replication

By applying a systems biology approach, a recent bioRxiv* preprint research paper by scientists from the Icahn School of Medicine at Mount Sinai in New York unveils interactions between the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) and p38 mitogen-activated protein kinase (MAPK) pathway responsible for regulating the expression of crucial inflammatory mediators in human lung epithelial cells.

Research shows how SARS-CoV-2 variants are evolving towards increased furin cleavage efficiency

The spike protein comprises of two subunits: S1 subunit having the receptor-binding domain (RBD) that helps it to bind to the angiotensin-converting enzyme 2 (ACE2), which is present on the cell surface of the host, and the S2 subunit that helps in the fusion of the cellular membrane and the viral membrane.
