I'm a little confused while cross-referencing between a few sources. My question is Beta-2 Adrenergic receptors role in insulin release? I used few sources and go contraindicating answers.
So basically my question is which one of these sources are correct? Only Lippincott's seems reasonable, because wouldn't insulin increase shut down lipolysis and glycogenolysis?? This has really been stressing me out. Any help would really be greatly appreciated.
- Lippincott pharm 4th edition says: B-2 receptors increase release of GLUCAGON?? + increased Glycongenlysis and Lipolysis and Alpha-2 decreases insulin release. (makes the most sense). ex; epinephrine causes hyperglycemia via this mechanism
- First Aid 2010: Beta 2= Increased Insulin Release + increased Lipolysis
- Kaplan lecture notes: Beta 2= Increased insulin release + increased Glycogenolysis (muscle and liver) + increased Gluconeogenisis. (It says "Mostly not innervated" not sure what they mean by that)
Thanks in advance
