Member of Eniko Sonkoly's research team Department of medicine, Solna Dermatology and venereology Our main scientific focus is to explore the role of a class of non-coding RNAs, microRNAs (miRNAs) in psoriasis, to understand their roles in regulatory pathways underlying chronic skin inflammation and explore their potential to become therapeutic targets and biomarkers for psoriasis. During my six months postdoc period, I was mainly involved in: - ImmunoHistoChemistry (IHC) and Immunofluorescence (IF) staining optimization of in vitro human skin and mice biopsie sections for several markers of psoriasis - The development of human reconstructed epidermis using immortalized and primary keratinocytes - The isolation of cKO keratinocytes from mice tails
