Dulbecco discovered that the integration of the viral genome with that of the host is responsible for the generation of tumors, [...]
The story of the Nobel laureate Salvatore Luria, a passionate scientist!
The intestinal mucosa is perpetually in contact with the food that is ingested and with potentially pathogenic bacteria that are introduced with it: the immune system distinguishes between what are simply nutrient molecules (proteins, lipids, etc.) and those that are proteins belonging to viruses or bacteria, allowing the absorption and entry only of non-hazardous substances.
