Tick hemocytes
WebbUsing RNAi-mediated silencing of tick thioester-containing proteins (TEPs), followed by in vitro and/or in vivo phagocytic assays, we found that C3-like complement components and α2-macroglobulin pan-protease inhibitors secreted to the hemolymph play pivotal roles in M. robertsii phagocytosis. Webb1 mars 2002 · Again, as in the previous experiment there was virtually no auto-fluorescence from tick hemocytes ensuring that fluorescence was attributed to the E. coli producing GFP.
