The interest in new physiological mechanisms based on nutrients contained in food increases continuously. This new technology based on transgenic stimulating the synthesis of specific proteins of each type of cell in the body has multiple applications in human and veterinary science.

The LEM (lymphocyte expansion molecule) is a recently discovered protein that regulates energy metabolism of cytotoxic T lymphocytes by increasing their ability to neutralize cancerous or infected cells, by intracellular microorganisms, causing their apoptosis.

Until now also known that nutrition foods rich in proanthocyanidins S. vaccinium polyunsaturated fatty acids and n-6 ​​soy increase the activity of T cells, suggesting that some pronutrients increase the synthesis of specific proteins.
