Abstract
Macrophage-derived foam cells play integral roles in all stages of atherosclerosis. These lipid-laden immune cells are present from the earliest discernable fatty-streak lesions to advanced plaques, and are key regulators of the pathologic behavior of plaques. This review summarizes the current understanding of the molecular mechanisms that regulate macrophage cholesterol uptake, foam cell formation, and lipid-driven pro-inflammatory responses that promote atherosclerosis. Specific emphasis will be placed on recent findings from mouse models of atherosclerosis regarding the pathways of macrophage differentiation into foam cells and their implications for developing macrophage-directed therapeutic targets.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
