Fatty liver disease, be it from alcohol (ALD), obesity (NAFLD) or other sources (e.g. viral infection), share similar mechanisms of disease progression. One potential mechanism is that altered sinusoidal endothelial cell (SEC) extracellular matrix (ECM) favors a more inflammatory phenotype in resident macrophages (i.e., Kupffer cells). Here, the hypothesis was tested that SEC-derived matrices directly affect the inflammatory response of macrophages. Methods. Transformed sinusoidal endothelial cells (TSECs) were cultured for 24 or 72 hours. Culture plates were then washed with a solution that selectively removed the cells, but preserved the ECM. Cultured macrophages (RAW 264.7 cells) were then seeded on …
