Alteration in contractile G-protein coupled receptor expression by moist snus and nicotine in rat cerebral arteries
The cardiovascular risk for users of use of Swedish snus/American snuff (moist tobacco) has been debated for a long time. The present study was designed to examine the effects of water- or lipid-soluble (DMSO-soluble) snus and nicotine, the most important substance in tobacco, on the expression of vasocontractile G-protein coupled receptors (GPCR), such as endothelin ETB, serotonin 5-HT1B, and thr
