Kurzbeschreibung (Abstract)
Inflammation and itch are common symptoms of various skin diseases and have major influence on the quality of life of affected patients. In the treatment of individuals with sensitive and psoriatic skin, several inflammation and itch related molecular and cellular targets have been identified but many of these have yet to be characterized. In this study, we present two potential targets in skin that can be linked to the inflammation and itch cycle. The enzyme 11ßHSD1 is responsible for converting inactive cortisone to active cortisol, which is used to transmit signals downstream. The activation of the receptor NK1R correlates with promoting inflammation and the perception of itch and pain in skin. In this study, both targets have been investigated based on their involvement in inflammation. The role of both identified targets were characterized based on the secretion of inflammatory cytokines- IL-6, IL-8, and CCL2, as well as phosphorylation and signaling pathways in keratinocyte like cells and primary keratinocytes. Mimicking signal transfer in cell culture with secretome transmission from treated keratinocyte like cells to immune like cells showed significant reduction of tested compounds. Treating skin cells with molecules able to inhibit inflammatory pathways result in the reduction of inflammatory signaling molecules secreted by skin cells. Therefore, these molecular targets and their associated pathways show therapeutic potential and can be mitigated via small molecules. This research can be used for further studies in inflammation and itch pathways and can help to treat the pathological symptoms.
