Exosomes isolated from serum of systemic sclerosis patients display alterations in their content of profibrotic and antifibrotic microRNA and induce a profibrotic phenotype in cultured normal dermal fibroblasts.

Abstract excerpt

OBJECTIVES: Exosomes are lipid bilayer-bound microvesicles containing various macromolecules including numerous microRNA (miRNA). Exosomes mediate intercellular communication by fusing and releasing their macromolecular content into target cells. Here, we analysed the content of profibrotic and antifibrotic miRNAs in exosomes isolated from the serum of systemic sclerosis (SSc) patients and tested their ability to...
