EBV might be capable of more than it seems
Ashton had been an advocate of the connection between EBV and MS far before his son's diagnosis. He believes a recent study is important to note, one that uncovered EBV's presence in the brain of most people who have MS.
The study he references implies that it is important to truly and meticulously analyze patients in examinations, as low levels of EBV are easy to miss. If the presence of EBV is not picked up on, when it is truly there, the data will be skewed.
This study also suggests that EBV may be capable and responsible for infecting multiple types of cells in MS. Such cell types include microglia and astrocytes, and as such a more dynamic relationship is created.
