Answer
The pattern recognition receptors recognize the pathogen or the parasite and antigen present in it by means of antigen presenting cells (APCs). After the antigen presentation to the helper T cells, the adaptive immunity is activated.
Work Step by Step
The recognition of the antigen present on the parasitic worm via the pattern recognition receptors transmits the recognition information to the antigen-presenting cells (APCs), lining the dendritic cells. These APCs initiates the helper T cells to become TH2 (T cell type 2) helper cells, which are responsible for the activation of the humoral response.
The humoral response is a type of adaptive immune response that is responsible for the production of antibodies after the antigen encounter. This response leads to a memory response and is retained within the individual pertaining to antigen.
