[Progress of researches on molecular mechanisms underlying helminth infection-mediated type 1/2 host immune responses].

Helminth infections are widespread worldwide, and pose a serious threat to human health and animal husbandry development. Understanding of helminth-host interactions is critical to effective control and ultimate eradication of helminthiasis. Following host infections, helminth infections firstly initiate innate immune responses and then mediate adaptive immune responses. Type 1 immune responses are predominant at early stage of helminth infections, which mainly play anti-infective actions, and type 2 immune responses are predominant at late stage of infections, which are associated with helminth immune evasion and aggravation of tissue damages. This review summarizes the progress of researches on type 1/2 immune responses-associated signaling pathways mediated by helminth infections in hosts.
