Peptidases in digestive cells in the gut of the hard tick \kur{Ixodes ricinus} - localization and function

Light microscopy was used to characterize digestive cells in the gut of the hard tick Ixodes ricinus during feeding and different phases of digestion. Indirect immunofluorescent microscopy was used to localize three digestive peptidases - cathepsin B, cathepsin L, cathepsin D in the gut of the hard tick Ixodes ricinus
