M3 Receptors
M3 receptors are members of the G-protein-coupled receptor (GPCR) family which are found mostly bound to Gq proteins. They are one of five muscarinic receptors that act to control the metabotropic functions of acetylcholine (ACh) in the central nervous system (CNS).

M3 receptors are members of the G-protein-coupled receptor (GPCR) family which are found mostly bound to Gq proteins. They are one of five muscarinic receptors that act to control the metabotropic functions of acetylcholine (ACh) in the central nervous system (CNS). M3 receptors are most densely populated in smooth muscle, endocrine and exocrine glands, lungs and CNS.
Activation of the M3 receptor leads to several responses, including the upregulation of phospholipase C, and inositol triphosphate (IP3), therefore increasing intracellular Ca2+. Hence, M3 receptor agonism can lead to smooth muscle constriction and bronchoconstriction. Conversely, receptor activation on vascular endothelial cells may upregulate the vasodilator nitric oxide (NO). Activation of M3 receptors also contributes towards many secretions (for example from the salivary gland, pancreas or stomach). Overall, M3 receptors are involved in numerous metabolic functions, including the maintenance of insulin release, regulation of glucose homeostasis.
M3 receptor antagonism is a potential therapeutic target in the treatment pulmonary obstructions. Activation of the M3 receptor by selective agonists may also be beneficial in the treatment of Type 2 diabetes.

Alzheimer's Disease Poster
Alzheimer's disease (AD) is a debilitating and progressive neurodegenerative disease and the most common cause of dementia, affecting approximately 30% of individuals aged over 85 years. This poster summarizes the cellular and molecular mechanisms of AD.
Learning & Memory Poster
Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
