Peptide-binding assays suggest that SARS-CoV-2 receptors engage the endocytosis and autophagy machinery.

there is interrelationship between the immune and nervous systems that is accomplished by the molecular mediators. dopamine is one of the most important neurotransmitters. five different dopamine receptor genes (drd1, drd2, drd3, drd4, and drd5) have been recognized and cloned. the expression of the dopamine receptors is well characterized in the brain but little work has been done to examine t...

Taste 2 receptors or Bitter taste (TAS2Rs) are G protein-coupled expressed in oral sensory cells and a variety of non-gustatory tissues. The ~25 human TAS2Rs share low amino acid sequence identities with other GPCR families classified as broadly tuned "generalist" numerous, chemically diverse bitter agonists, narrowly "specialist" very few activators, intermediately an average number specialize...

angiotensin-ii is a multifunctional hormone that regulates blood pressure, plasma volume, neuronal functions, electrolyte balance, thrust and various other vital mechanisms. it acts through its receptors at 1 and at 2 . the involvement of angiotensin-ii and its receptors in cognition is still ambiguous. therefore, the present study was designed to investigate the effect of angiotensin-ii (2 μg/...

background and objectives: cyclooxygenese-2 (cox-2) expression in breast cancer and its correlation with tumor prognosis is unclear. we investigated the incidence of cox-2 expression in patients and assessed interactions between cox-2 and clinical features of cancer and expression of her2/neu, estrogen receptor (er), and progesterone receptor (pr). methods: cox-2 expression was investigated by...
