Bias and allostery at the calcium sensing receptor. This project aims to provide a mechanistic and dynamic picture of the structure, function and physiology of the human calcium sensing receptor (CaSR), which is critical for vertebrate life. By responding to chemicals in the body, it acts as a universal nutrient sensor to maintain extracellular calcium homeostasis and mediate biological functions, including neurotransmission, inflammation, digestion, blood pressure and development. However, it i ....Bias and allostery at the calcium sensing receptor. This project aims to provide a mechanistic and dynamic picture of the structure, function and physiology of the human calcium sensing receptor (CaSR), which is critical for vertebrate life. By responding to chemicals in the body, it acts as a universal nutrient sensor to maintain extracellular calcium homeostasis and mediate biological functions, including neurotransmission, inflammation, digestion, blood pressure and development. However, it is not known how this single receptor controls the actions of multiple ligands to mediate numerous functions. By elucidating the roles of the CaSR and its ligands, this project aims to better understand fundamental physiological processes.Read moreRead less
A new understanding of responsibility in the ethics of human reproduction. New developments in reproductive medicine and prenatal testing technologies are transforming pregnancy and generating difficult moral and policy questions for parents and the Australian community. This project will provide a new framework for reproductive responsibility that helps to ensure a healthy start to life for all Australians.
A new ethics for the development and application of genetic technologies in a pluralist society. New technologies for prenatal testing and preimplantation genetic diagnosis will soon grant us an unprecedented power to choose our children's genes. This project will develop an ethical framework to govern the development and use of these technologies and thus help ensure that future Australians enjoy a healthy start to life.
