Study the mechanism regulating matrix gene expression in Fibro/adipogenic progenitors (FAPs) in vitro and identify novel compounds that modulate it in vivo.
I’m interested in understand how fibrosis process is regulated in skeletal muscle, specially focusing in a non-myogenic mesenchymal stem cells called Fibro/adipogenic progenitors (FAPs) and study molecular pathways that regulate this process. This might open new opportunities for designing therapeutic strategies for muscle diseases.
Recently, has been demonstrated that TGF-b induced the expression of fibrosis markers in mesenchymal progenitors (FAPs) but not in myogenic cells. This evidence shows that FAPs are the main cells responsible of fibrosis in skeletal muscles and that TGFb is a potent mediator in this effect. Therefore, we hypothesize that FAPs and the TGFb pathway are promising therapeutic targets to inhibit fibrosis in DMD and other fibrotic diseases. However more studies are needed to determine whether if other molecular ways are involved in this process and if TGFb antagonist treatments can improve muscle function impaired by fibrosis.
Once I finished my PhD at University of Concepción, where I studied the dynamic of vitamin C transporter (SVCT2) in muscle differentation, I moved to University of Chile where I did a Postdoctoral research about gene expression regulation in bacteria against metal exposure. My interest in the potential of muscle stem cells in regenerative medicine led me to here.
I like to enjoy with family and friends, reading books, practice outdoor activities, like skiing, hiking, biking, running.
