Dual SPI1 Inhibition for Atherosclerosis-Neurodegeneration Axis

Mechanistic description

Since SPI1 regulates inflammatory responses in both peripheral atherosclerosis and central neuroinflammation, a brain-penetrant SPI1 modulator could simultaneously target vascular disease and prevent secondary neurodegeneration. This represents a novel vascular-neural protection therapeutic strategy.
