Principal Investigator: Prof. Elena Bianca Donetti

Collaborators: Dr. Francesca Arnaboldi, Dr. Laura Cornaghi, Dr. Federica Landoni



The activity of the group is focused on the following research lines:

  • acute effects of proinflammatory cytokines involved in psoarias pathogenesis in a three-dimensional model of organotypic culture of normal human skin
  • chronic and acute effects induced by exogenous stimuli in a three-dimensional model of organotypic culture of normal human skin and oral mucosa
  • correlation between intercellular adhesion and cell differentiation in simple and stratified epithelia

Considered parameters

  • intercellular adhesion (desmosomes, tight/adherens junctions)
  • cell proliferation

figure 2

  • cell differentiation in stratified squamous human epithelia
  • apoptosis

Methods

light microscopy

- indirect immunofluorescence on cell culture and tissue sections (both frozen and paraffin embedded)

- digital microphotography and image analysis with an appropriate software

transmission electron microscopy
