Intestinal permeability and the translocation of bacteria, viruses and antigens through the mucosal epithelium seems to play a role in many illnesses from celiac disease over diabetes to HIV and immune activation. Do we take into account that intestinal permeability could play a very important r... Read More
How many different viruses are there on planet Earth? Twenty years ago Stephen Morse suggested that there were about one million viruses of vertebrates (he arrived at this calculation by assuming ~20 different viruses in each of the 50,000 vertebrates on the planet). The results of a new study s... Read More
