This study analyzes the mechanisms of long-chain fatty acid (LC311) uptake by human microvascular endothelial cells (HMEC). The time course revealed the presence of an early, carrier-mediated uptake component and a later component mediated by clathrin-coated vesicles (CCV) and caveolae, as evidenced by three different experimental approaches: 1) significant reduction of [3H]oleate uptake over 5 by of by of by of acid and of [3H]oleate a and of [3H]oleate the and as The uptake of of the of and the uptake of and a of the a of and the uptake of by This study analyzes the mechanisms of long-chain fatty acid (LC311) uptake by human microvascular endothelial cells (HMEC).
