HHV-6 and Dendritic Cells

 Dendritic cells.jpgDendritic cell revealed.jpg

 Dendritic cells (DCs) are antigen-presenting cells, (also known as accessory cells) of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They act as messengers between the innate and the adaptive immune systems.

Human herpesvirus 6 impairs differentiation of monocytes to dendritic cells

"OBJECTIVE:Monocyte-derived dendritic cells (DCs) play important roles in the immune response against infections and malignancies. Human herpesvirus 6 (HHV-6) infects monocytes and is reactivated in immunodeficient patients. To clarify the mechanisms of HHV-6-induced immunodeficiency, we investigated the effect of HHV-6 infection on differentiation of monocytes to DCs."

Phenotypic and functional alterations of dendritic cells induced by human herpesvirus 6 infection.

"The present data also suggest that the dysfunction of HHV-6-infected DCs is attributable mainly to impairment of the antigen capture and intracellular antigen-processing pathways."

" A new study finds that prior herpesvirus infections are linked to a faster age-related increase in blood biomarkers associated with dementia, even in cognitively healthy women. Researchers measured five key biomarkers in 167 women and found that seropositivity for HHVs doubled the rate of biomarker accumulation compared to those without prior infection. The strongest viral associations were seen for Epstein-Barr virus and HHV6, with amyloid-beta and phosphorylated tau levels most affected. These findings support the hypothesis that chronic viral infections may accelerate neurodegeneration and raise dementia risk independently of genetic factors."
