Popis: Schistosome infections are characterized by prominent T cell hyporesponsiveness during the chronic stage of infection. We found that schistosome-specific phosphatidylserine (PS) activated TLR2 and affected dendritic cells such that mature dendritic cells gained the ability to induce the development of IL-10-producing regulatory T cells. Using mass spectrometry, schistosomal lysophosphatidylserine (lyso-PS) was identified as the TLR2-activating molecule. This activity appears to be a unique property of schistosomal lyso-PS, containing specific acyl chains, because neither a synthetic lyso-PS (16:0) nor PS isolated from the mammalian host activates TLR2. Taken together, these findings provide evidence for a novel host-parasite interaction that may be central to long term survival of the parasite and limited host pathology with implications beyond parasitology
