Provided are processes for the prevention or treatment of viral infection in a subject. Some aspects provide administration of a sphingoid compound, optionally sphingosine, an active ingredient that activates generation of a sphingoid base, optionally of sphingosine; or an active agent that inhibits the degradation of a sphingoid base, optionally of sphingosine, to a subject such as a human. By increasing the local concentration of sphingosine in a subject or an area of a subject to which the composition is administered such as the nose or interior of the nose or portion thereof, the ability of viruses to infect the subject or cells thereof is reduced thereby treating of preventing infection by the virus.
本文提供了预防或治疗受试者病毒感染的方法。某些方面提供了向人等受试者施用
鞘氨醇化合物(可选
鞘氨醇)、激活生成
鞘氨醇基(可选
鞘氨醇)的活性成分;或抑制
鞘氨醇基(可选
鞘氨醇)降解的活性剂。通过增加施用组合物的受试者或受试者的局部(如鼻子或鼻子内部或其部分)的
鞘氨醇浓度,可降低病毒感染受试者或其细胞的能力,从而达到预防病毒感染的目的。
