As reported on 29 October 2019 in the Harvard Health Blog, clinical studies are revealing that people with an optimistic outlook on life tend to live longer. This comes as no surprise to the researchers and scientists at biosyn. They have known for decades that there is an association between immune response and optimism. Back in 2008, KHL, the hemocyanin extracted from the Great Keyhole Limpet, was used to measure immune function and determine that when immunity is enhanced, optimism is too. Study of the strong immune reaction triggered by KLH also allows medical science to gain insights into many other immune functions like how the elderly react to the vaccines they need to keep healthy. As a very large protein, KHL is a strong antigen that induces the immune system to activate macrophages that eliminate diseased or cancerous cells. This is one mechanism by which biosyn’s IMMUCOTHEL® destroys bladder carcinoma cells.
