WebJul 26, 2024 · Furthermore, dyslipidaemia causes inflammatory responses and foam cell formation. Mechanistic target of rapamycin (mTOR) signalling is a key regulator of diverse cellular processes, including cell metabolism and cell fate. mTOR complex 1 (mTORC1) is involved in lipid metabolism and immune responses in the body. WebApr 29, 2011 · Foam Cells. Even at very early stages of atherogenesis, many macrophages and dendritic-like cells have membrane-bound lipid droplets in the cytoplasm. These lipid-loaded cells are called “foam cells,” and their formation begins when phagocytes ingest and process apoB-LPs (Figure 2 and Movie S1). The mechanism of this uptake is a …
