Psoriasis is a common inflammatory skin disease,which considerably affects the quality of life of those that suffer from it. According to a new study, the antigens of the bacteria Streptococcus pyogenes are directly related to the immunological mechanisms that trigger lesions in psoriasis sufferers. This is one of the main conclusions of a scientific article of the translational research group in immunodermatology directed by Dr. Luis Francisco Santamaria, lecturer in Immunology of the Department of Phisiology and Immunology from the Faculty of Biology and the Barcelona Science Park.

The scientific study establishes a new ex vivo model that enables understanding the beginnings of psoriasis lesions through the interaction between the Streptococcus pyogenes bacteria, positive TCLA lymphocytes and epidermal cells. This line of research opens up a new scenario from a more translational perspective in order to understand the induction processes of psoriasis lesions.
