Coronavirus, SARS‐Cov‐2 infects a humain cell, the virus enter by using a spike protein attache to a receptor on cells called ACE2
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
