Antibiotics alter GI tract microbes and increase lung sensitivity to allergens
...lls from the GI tract, T cells in the lungs become sensitized
to the presence of ordinary mold spores, pollen or other allergens. The result is a hyperactive immune response, which can produce allergy symptoms or even asthma. To test Huffnagle's hypothesis, Mairi C. Noverr, Ph.D., a U-M research fellow in inter...
