Even tho EBV infects B cell,why does T cell hyperplasia occur in LN and sleen resulting in splenomegaly and lymphadenopathy respectively? pathogenesis plz!
EBV turns on the oncogenes within B-Cells, leading to a perpetual activation of pathways of B-Cell proliferation and anti-apoptosis. Now, as you know that body's response to a virally infected cell is chiefly a cell mediated response and to control such a high number of cells with infective virion inside them, we need an equally large army of T-Cells and hence the hyperplasia in nodal paracortex and splenic PALS.
Feel free to ask if I am not being clear enough.
