1 Herpes Simplex Virus Type 1 And Apolipoprotein-E In Alzheimer’S Disease: Virus Entry And Innate Immunity, Jim Camilleri

College of Science and Health Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a neurotropic virus that has been detected in brains affected by Alzheimer’s Disease (AD), the leading global cause of cognitive decline. In vitro and epidemiological studies support a role for HSV-1 in AD. The strongest genetic risk factor for late-onset AD is the E4 allele of APOE, which codes for apolipoprotein-E (ApoE), a protein that mediates brain cholesterol homeostasis. Previous work has suggested that ApoE can affect HSV-1 entry into cells; however, APOE has three alleles (E2, E3, and E4) and allelespecific effects of ApoE on HSV-1 entry remain undetermined. We hypothesized that …
