Experts speculate HCMV may travel via the vagus nerve from the colon to the brain where it triggers the onset of AD.

"The team hypothesised that some of the T cells specific to SARS-CoV-2 had been activated by a herpesvirus called human #cytomegalovirus (HCMV). This pathogen is highly prevalent in the population and has also been linked to changes in the severity of #COVID19 symptoms (Alanio et al., 2022). To investigate, they stimulated pre-pandemic blood samples with different segments of SARS-CoV-2 proteins. This led them to discover a population of ‘cross-reactive’ CD4 and CD8 T cells that can recognize epitopes from both #SARSCoV2 and #HCMV"

T Cells: Ready and waiting to go

Some T cells that have been activated by a herpesvirus can also respond to SARS-CoV-2, even if the original herpesvirus infection happened before the COVID-19 pandemic.
