Exploring of blood viscosity in injured liver tissues of hyperlipidemic mice

Exploring the connection between blood viscosity and liver in it have great significance for the detection and treatment of hyperlipidemic. Therefore, we designed a new near-infrared viscosity sensitive fluorescent probe Vis-LW based on the twisted intramolecular charge transfer mechanism. The probe exhibited a strong dependence on viscosity as well as good anti-interference performance. With the aid of Vis-LW, we successfully detected the viscosity changes in chloroquine induced cells and realized the diagnosis of diseases in hyperlipidemic mice by utilizing blood viscosity as a diagnostic indicator for hyperlipidemia. Not only that, the increased liver viscosity of hyperlipidemic mice was found for the first time, the reduced blood and liver viscosity after treatment with lipid-lowering drug fenofibrate was also tracked. This work provides a new method for the diagnosis of hyperlipidemia and offered a new idea on the research and treatment of hyperlipidemia in the future.
