Mye-EUNITER
 

Cichy, Joanna

Research interests focus on the role of proteolytic enzymes and their inhibitors in regulation of immune responses with a particular emphasis on the mechanisms underlying autoimmunity. Major current focus include; i/ understanding the molecular interplay between proteases, protease inhibitors  and neutrophil, macrophage and DCs function in inflammatory diseases, ii/ understanding the role of proteolitically controlled antimicrobial protein-chemerin in skin pathophysiology.

Models available:

  • Psoriasis (human and mouse)
  • SLE (human),
  • Skin-infection (mouse),
  • Human samples (blood & tissue).

Cells available:

  • Neutrophils,
  • Macrophages,
  • Plasmocytoid dendritic cells

Technology available:

Flow cytometry (9-colour LSRII), magnetic cell sorting (AutoMacs), Fluorescence microscopy (Nikon), 3D (organotypic) cultures of human keratinocytes, Transwell chemotaxis assays. Cutaneous infection model. Mouse models (KO) to study role of proteolytic enzymes and their inhibitors in myeloid cells.
