Demographic changes and increased life-span in western countries have resulted in a progressive ageing of populations. One of the major features of ageing is sarcopenia, which is a physiological and involuntary loss of muscle mass and strength. This feature is common to all older individuals, including healthy ones, and is considered to be one of the most important causes of disability, frailty and morbidity in the senior population. Therefore, preventing muscle protein mass loss in specific population contributes to maintain autonomy and healthy conditions and to the reduction of public health care costs.

It is very likely that the age-related loss of muscle proteins is aggravated by a decreased arterial availability of nutrients. The amino acid (AA) bioavailability depends firstly on the nature and quantity of ingested proteins and secondly on the metabolic activity of the tissues using AA and competing with the muscle for nutrients use. Among these competitors, tissues from the splanchnic area (gut and liver) play a key role. Any specific increased utilization of one or several available AA by these organs will necessarily negatively impact on muscle protein anabolism.

My research program focuses on the fate of dietary protein within the digestive tract (digestibility, digestion rate, released peptides), and the metabolism of amino acids within the gut and the liver.
