Our body has multiple receptors that detect nutrients and ensure that the body responds appropriately to convert nutrients to energy or use them as building materials. Many of these receptor has potential as drug targets. For example, the medium- and long-chain fatty acid receptors FFA1 and FFA4 are recognized as promising targets for treatment of metabolic diseases such as type 2 diabetes and metabolic dysfunction-associated steatohepatitis (MASH), and activation of the receptors is expected to give the therapeutic effect. This implies that medium and long-chain fatty acids has therapeutic potential through activity on these receptors. Our FFARMED project was set up to explore this potential.
