Acute helminth infection is associated with a local innate response and an adaptive Th2-type response, but in chronic stages, these parasites also have the ability to suppress the immune system by increasing the levels of interleukin (IL)-10 and regulatory T cells, which could explain the inverse relationship of these infections with allergies, such as asthma and atopy [19,34,35]. Here, IL10 is linked to allergic disease.
