Researchers found an association between larger households and higher naive regulatory T-cell levels, which in turn were associated with less allergic sensitization and disease at age 12 months, according to a study.
There also were associations between multiple prenatal and postnatal microbial factors and the development of naive T regulatory (nTreg) and activated T regulatory (aTreg) cells, the researchers wrote in the study, published in Pediatric Allergy and Immunology.
