Chromosomally integrated human herpesvirus 6 (ciHHV-6) is a condition in which the complete HHV-6 genome is integrated into the host germ line genome and is vertically transmitted in a Mendelian manner. The condition is found in less than 1% of controls in the USA and UK, but has been found at a somewhat higher prevalence in transplant recipients and other(More)
OBJECTIVE We examined the frequency and characteristics of chromosomally integrated human herpesvirus 6 among congenitally infected children. METHODS Infants with and without congenital human herpesvirus 6 infection were prospectively monitored. Cord blood mononuclear cell, peripheral blood mononuclear cell, saliva, urine, and hair follicle samples were(More)
Prenatal anxiety has been linked with altered immune function in offspring in animal studies, but the relevance for human health is unknown. We examined prenatal maternal anxiety as a predictor of adaptive immunity in infants at 2 and 6 months of age as part of a prospective longitudinal study. The humoral immune response to hepatitis B vaccine was assessed(More)
Neuropeptide Y (NPY)-containing neurons are depleted in the cortices of individuals with Alzheimer disease (AD), yet spared in the striatum of patients with Huntington chorea. It is unknown whether this neuronal phenotype is inherently susceptible to the neurodegenerative processes that are a hallmark of AD. To study this question, the murine trisomy 16(More)
The role of human herpesvirus 6 (HHV-6) in disease beyond primary infection remains unclear. We have developed and validated a new reverse transcription-PCR (RT-PCR) assay for HHV-6 that can determine the presence of HHV-6 in clinical specimens and differentiate between latent and replicating virus. Peripheral blood mononuclear cells from 109 children were(More)
OBJECTIVE Family processes have a substantial impact on children's social and emotional well-being, but little is known about the effects of family stress on children's physical health. To begin to identify potential links between family stress and health in children, we examined associations between specific aspects of family psychosocial stress and the(More)
Experimental animal and adult human data suggest that stress exposure is associated with alterations in immune system function that may underlie increased susceptibility to disease and behavioral disorders. The implications of these data for child psychology and psychiatry are not yet clear. The current review seeks to distil and translate the relevant(More)
Experimental animal studies and adult research consistently show that stress exposure and/or psychological symptoms are associated with poorer health and immune functioning. The application to children is not yet clear, however, and we lack developmental models for studies in this area. The objective of this paper was to test the hypothesis that(More)
The gene encoding for pre-prosomatostatin is located on chromosome 16 of the mouse. To determine the effect of an extra copy of this gene on somatostatin expression in neurons, primary disaggregated cultures of neocortex prepared from 15 days gestational Trisomy 16 mice and their littermate euploid controls were subjected to immunocytochemical staining for(More)
OBJECTIVE The goal of this study was to determine if congenital human herpesvirus-6 (HHV-6) infection influences early neurodevelopment. METHODS We enrolled 57 newborns with HHV-6 congenital infection and 242 control newborns without congenital infection into a prospective, double-blind study with 4 visits between 4 and 30 months of age.
