The immune system has two sides the cellular part and the humoral part which includes the methylation cycle.. If either are not functioning properly this termed immune dysfunction. The cellular part includes the white cells. One type of white cells are the T cells,. The natural killer cells, a type of phagocyte, are active against various invasion. Dr Yamamoto in the 1990’s researched the action of NK cells. He discovered a natural stimulant produced normally in the human body this substance is termed Macrophage Activting Factor (MAF) . MAF occurs in minute microscopic amount , in certainn conditions where the immune system is under stress, MAF is reduced. MAF is not only produced by the human but certain strains of probiotic bacteria when they replicate also can produce MAF .
The probiotic bacteria in MAF 878 (TM) starter produce a Natural Killer (NK) cell stimulant , increasing NK cells in number and function.
