Helminth infections activate regulatory T (Treg) cells and induce the production of interleukin 10 (IL‐10), and thus, play a protective role against asthma and allergy.8 Studies have shown that IL‐10 induced in chronic schistosomiasis appeared to be central to suppressing atopy in African children,8 and infection with Schistosoma mansoni has been associated with a reduced course of asthma.9 Nevertheless, this suppressive function remains poorly understood in the context of Ascariasis, in contrast to Schistosomiasis. The gene discussed is IL10; the disease is asthma.
