| Abstract: | Mesenchymal stromal cells(MSCs) possess great therapeutic advantages due to their ability to produce a diverse array of trophic/growth factors related to cytoprotection and immunoregulation.MSC activation via specific receptors is a crucial event for these cells to exert their immunosuppressive response.The aryl-hydrocarbon receptor(Ah R) is a sensitive molecule for external signals and it is expressed in MSCs and,upon positive activation,may potentially regulate the MSC-associated immunomodulatory function.Consequently,signalling pathways linked to Ah R activation can elucidate some of the molecular cascades involved in MSC-mediated immunosuppression.In this minireview,we have noted some important findings concerning MSC regulation via Ah R,highlighting that its activation is associated with improvement in migration and immunoregulation,as well as an increase in pro-regenerative potential.Thus,Ah R-mediated MSC activation can contribute to new perspectives on MSC-based therapies,particularly those directed at immune-associated disorders. |
