Regulatory T Cells Modulate Th2 Responses Induced byBrugia pahangiThird-Stage Larvae

Abstract excerpt

Infection of BALB/c mice with Brugia pahangi third-stage larvae (L3) results in the production of interleukin-4 (IL-4), IL-5, and IL-10 with a resultant down-regulation in Th1 responses. Previously, this was thought to reflect a skewing of immune responses towards a Th2 phenotype by the infective stage of the parasite. In this study, we show that exposure to the L3 of Brugia also induces the expansion of a...
