摘要
<正>Distinct migratory pathways and trafficking of dendritic cells to the central nervous system (CNs):The immune system is a host defense mechanism protecting against invaders, such as bacteria and viruses,while maintaining tolerance to self. Nonetheless, a few sites throughout the body are believed to be immunologically inert, such as the testes,the eye and the brain. Indeed, experiments in the mid-20~(th) century gave
