O.k. I don't know. I don't understand how digestive enyzmes would work to suppress an immune system. There are many phagocytes in connective tissue waiting to investigate anything of something does happen. I don't understand how digestive enzymes would alter their behavior be it dendritic cells, neutrophils, macrophages and the like. Fasciola flukes emit interluekins to favor their behavior, suppress th1 immunity and disable th2 immunity to eliminate eosinophil activation. I don't see how digestive enzymes would be able to do that.
What I meant by highly advanced researchers were PhD parasitologists or someone of that nature. Whatever your belief of the next life is. I sincerely hope there aren't parasites there.
Sorry for the delayed response. I was moving.
