TLR signalling - Answer TLRS recognize through ramps or damps, then the engulfed pathogen is presented to the MHC and the production of co-stimulatory molecules is increased, and an immunocompetent naive T cell binds to the MHC and can initiate an adaptive IR. Humoral Activation - Answer Activated and differentiated TH2 cells activate B cells and induce their differentiation into plasmocytes. Plasmocytes then secrete a large number of antibodies for the invading antigen.
