WebHeligmosomoides polygyrus bakeri is a trichostrongylid nematode of rodents, inducing early Th2-dominant responses followed by a robust Treg expansion and release of IL-10 and TGF-β. Expansion of regulatory T cells appears to be parasite-mediated, via secretion of an immunomodulatory TGF-β-like ligand. WebIt has been widely accepted that a Th2-mediated response plays a critical role in the host defense against helminth infec-tions (11, 22), primarily those caused by gastrointestinal nem-atodes (48). However, several reports have shown that some stages of helminth parasites are not efﬁciently controlled by speciﬁc Th2-type responses.
