Non-alcoholic fatty liver disease (NAFLD) is a dominant cause of chronic liver
disease, but the exact mechanism of progression from simple steatosis to
nonalcoholic steatohepatitis (NASH) remains unknown. Here, we investigated the
role of exosomes in NAFLD progression. Exosomes were isolated from a human
hepatoma cell line treated with palmitic acid (PA) and their miRNA profiles
examined by microarray. The human hepatic stellate cell (HSC) line (LX-2) was
then treated with exosome isolated from hepatocytes. Compared with controls,
PA-treated hepatocytes displayed significantly increased CD36 and exosome
production. The microarray analysis showed there to be distinctive miRNA
expression patterns between exosomes from vehicle- and PA-treated hepatocytes.
When LX-2 cells were cultured with exosomes from PA-treated hepatocytes, the
expression of genes related to the development of fibrosis were significantly
amplified compared to those treated with exosomes from vehicle-treated
hepatocytes. In conclusion, PA treatment enhanced the production of exosomes in
these hepatocytes and changed their exosomal miRNA profile. Moreover, exosomes
derived from PA-treated hepatocytes caused an increase in the expression levels
of fibrotic genes in HSCs. Therefore, exosomes may have important roles in the
crosstalk between hepatocytes and HSCs in the progression from simple steatosis
to NASH.
