- Epinephrine binds to both β-adrenergic and α-adrenergic receptors. Describe the opposite actions on the effector protein, adenylyl cyclase, elicited by the binding of epinephrine to these two types of receptors. Describe the effect of adding an agonist or antagonist to a β-adrenergic receptor on the activity of adenylyl cyclase.The following diagram represents a typical serotonergic synapse. Where, specifically, do antidepressants work (e.g. SSRI)? Neurotransmitter Neurotransmitter transporter Аxon Synaptic vesicle terminal Voltage- gated Ca?+ channel Synaptic cleft Receptor Postsynaptic density Dendrite Neurotransmitter Synaptic Vesicle Neurotransmitter transporter (aka Reuptake transporter) Receptor O All of the aboveA patient has been exposed to the organophosphate pesticide malathion,which inactivates acetylcholinesterase. Which of the following symptoms would you predict: blurring of vision, excess tear formation, frequent or involuntary urination, pallor (pale skin), muscle twitching, orcramps? Would atropine be an effective drug to treat the symptoms?(See Clinical Impact 16.2 for the action of atropine.) Explain.
- In a cell line derived from normal rat thyroid, stimulation of the alpha1-adrenergic receptor increases both IP3 formation and release of arachidonic acid (AA). IP3 elevates cytosolic Ca, which mediates thyroxine efflux, whereas AA serves as a source of prostaglandin E2, which stimulates DNA synthesis. It is not clear how AA release is connected to the adrenergic receptor. AA could arise by cleavage from the DAG that accompanies IP3 production. Alternatively, AA could arise through an independent effect of the receptor on PLA2, which can directly release AA from intact phosphoglycerides. Consider the following experimental observations: a) Addition of noradrenaline to cell cultures stimulates production of both IP3 and AA. b) If the alpha1-adrenergic receptors are made unresponsive to noradrenaline by treatment with phorbol esters (which act through PKC to cause phosphorylation, and inactivation, of the receptor), addition of noradrenaline causes no increase in IP3 or AA. c) When…Identify the structure highlighted in green: Epinephrine receptor ACh receptor Norepinephrine receptorWhat are tyrosine kinase and GPCR? Give example of one pathology that can occur in dysregulation/impaired function for each of these. Hypothetically, how can you rescue the pathologies pharmacologically?
