The story of 4Life Transfer Factor is one of innovation. It all started when Founder and CEO David Lisonbee began research to better support his own health and the health of his family. That was just the beginning.
But these things take time, the Lisonbees say. They resisted, and it paid off. Now they are big guns, at No.
We are Heading to the right direction 4LIFE!
Doctor Henry Sherwood Lawrence was a distinguished physician, master teacher, and a pioneer in research on cell-mediated immunity. At a time when scientists focused on the more popular study of humeral immunity and the nature of immunoglobulins in experimental animals, Lawrence emphasized the role of cellular immunity in human responses to disease and antigenic agents. He was a highly regarded clinician with a special expertise in infectious diseases, and a dedicated teacher and role model for students, residents, fellows, and young physicians. In , Doctor Lawrence made a very significant discovery. In the process of studying tuberculosis, which was a major health threat at the time, he discovered an immune response could be transferred from a donor to a recipient through an injection of an extract of leukocytes white blood cells. From this discovery, research began its journey through the s, s, and s. Scientists believed that they had found that ultimate immune system and health enhancer.
Transfer factors are essentially small immune messenger molecules that are produced by all higher organisms. They have a molecular weight of approximately Daltons and are composed entirely of amino acids. A second use of the term transfer factor applies to a likely different entity  derived from cow colostrum or chicken egg yolk which is marketed as an oral dietary supplement under the same name citing claims of benefit to the immune system. In , Merrill Chase discovered that cells taken from the peritoneum of Guinea pigs that had been immunized against an antigen could transfer immunity when injected into Guinea pigs that had never been exposed to the antigen; this phenomenon was the discovery of cell-mediated immunity. Subsequent research attempted to uncover how the cells imparted their effects. Henry Sherwood Lawrence , in ,  discovered that partial immunity could be transferred even when the immune cells had undergone lysis - indicating that cells did not need to be fully intact in order to produce immune effects. The history of cellular derived transfer factor as a treatment effectively ended in the early s.
