DEFECTIVE HSV-SPECIFIC IMMUNITY FOLLOWING NEONATAL HSV ENCEPHALITIS

Replication-defective mutants of herpes simplex virus (HSV) induce cellular immunity and protect against lethal HSV infection.

Live viruses and live virus vaccines induce cellular immunity more readily than do inactivated viruses or purified proteins, but the mechanism by which this process occurs is unknown. A trivial explanation would relate to the ability of live viruses to spread and infect more cells than can inactivated virus. We have used live but replication-defective mutants to investigate this question. Our s...

A rare case of HSV-2 encephalitis.

Herpes simplex viruses (HSV), and especially HSV-1, are the most common cause of acute, sporadic viral encephalitis. HSV-2 is an uncommon cause of encephalitis. We report a rare case of HSV-2 encephalitis that was free of genital lesions. In terms of the patient's case history, she had a Cesarean section four months before, herpes labialis 30 days before, varicella zoster 20 days before. We dis...

[18F]FHPG positron emission tomography for detection of herpes simplex virus (HSV) in experimental HSV encephalitis.

Herpes simplex virus type 1 (HSV-1) is one of the most common causes of sporadic encephalitis. The initial clinical course of HSV encephalitis (HSE) is highly variable, and the infection may be rapidly fatal. For effective treatment with antiviral medication, an early diagnosis of HSE is crucial. Subtle brain infections with HSV may be causally related to neuropsychiatric disorders such as Alzh...

Protection from herpes simplex virus (HSV)-2 infection with replication-defective HSV-2 or glycoprotein D2 vaccines in HSV-1-seropositive and HSV-1-seronegative guinea pigs.

BACKGROUND A herpes simplex virus (HSV)-2 candidate vaccine consisting of glycoprotein D (gD2) in alum and monophosphoryl lipid A (MPL) reduced genital herpes disease in HSV-1-seronegative women but not in men or HSV-1-seropositive women. METHODS To determine the effect of HSV-1 serostatus on effectiveness of different vaccines, we tested gD2 in alum/MPL, gD2 in Freund's adjuvant, and dl5-29 ...
