Funded Activity Summary

The normal function of all living cells depends on how they respond to the multitude of physical and chemical stimuli to which they are constantly exposed. The majority of chemical stimuli acting on cells do so not by directly entering the cell, but rather by acting on specific types of receiver proteins on the cell's surface called receptors. One important family of receptors transmit their message to the inside of the cell by coupling to yet another type of protein known as the G protein. Aberrations in the normal function of these G protein-coupled receptors have been implicated in a wide variety of disorders, such as schizophrenia, pain and dementia. To date, most therapeutic approaches to treating these disorders have targeted individual types of G protein-coupled receptors thought to play a role in each disease state, but this has met with mixed success. One of the reasons for this is that each disorder actually involves more than one type of G protein-coupled receptor communicating with other types in a complex way. Our current proposal specifically focuses on some of the newer mechanisms that have been suggested to play an important role in the communication between different types of G protein-coupled receptors located in the same type of cell. An understanding of how such receptor proteins can communicate with one another in this situation is absolutely vital in unravelling processes involved in the maintenance of health, abnormalities that lead to disease and in the development of more effective treatments.
