MNF also alleviated myocardial ischemia/reperfusion injury. In cultured rodent cardiomyocytes, MNF inhibited DNA damage and cell death caused by Dox, H O or hypoxia/reoxygenation. Mechanistically, we found that MNF or another β -agonist zinterol markedly promoted heterodimerization of β -ARs with 5-HT Rs. Upregulation of the heterodimerized 5-HT Rs and β -ARs enhanced β -AR-stimulated G -Akt signaling and cardioprotection while knockdown or pharmacological inhibition of the 5-HT R attenuated β -AR-stimulated G signaling and cardioprotection. These data demonstrate that the β -AR-stimulated cardioprotective G signaling depends on the heterodimerization of β -ARs and 5-HT Rs. These data demonstrate that the β2-AR-stimulated cardioprotective Gi signaling depends on the heterodimerization of β2-ARs and 5-HT2BRs.Recently, there has been a growing interest in the use of cannabis after traumatic brain injury (TBI); however, little is known about the long-term effects of cannabis on milder injuries and post-concussive symptoms. Further, substance use often increases post-TBI and, thus, individuals who chronically use cannabis may unknowingly be exceeding safe or therapeutic doses. The current cross-sectional study explores the prevalence of cannabis use among university students with and without a history of concussion and examines the relationship between concussion and post-concussive symptoms as a function of cannabis use. Eighty-four undergraduates (n = 51 without a prior concussion; n = 33 with a prior concussion) completed a series of questionnaires, capturing their head injury history, current and past substance use, and post-concussive symptomatology. Results indicated that those with a history of concussion were more likely to use cannabis and had higher cannabis use
