You must answer all the questions in this section
1. Define ‘efficacy’. [2 marks]
Using the term efficacy, explain the difference between inverse agonism and agonism. Summarise this in a diagram of a dose-response curve.
3. Write a few sentences paraphrasing (in your own words) the aim of the
study written by Wisler et al.,2007.
Draw at least one diagram to summarise the signalling pathways that mediate G-protein-dependent and -independent signalling of the B2- adrenergic receptor. [12 marks]
Explain why HEK293 cells were chosen for the experiments in the Wisler et al. study. [2 marks]
What roles do isoproterenol and propranolol play on the experiments of Wisler et al. 2007? [4 marks]
What is the role of the B2AR TYY mutant in the Wisler et al. study? Explain the meaning of figure 2 in your answer. [8 marks]
What is the role of the siRNA targeting B-arrestin 2 in the Wisler et al. study? Explain Fig 5 in your answer. [10 marks]
