My daughter's NK cell function improved from low to high normal after treatment with inosine. Although her NK cell
function has increased, her numbers are still very low.

She is currently in remission (depending on your definition of remission), but we do not attribute that to inosine. She improved substantially before she took inosine.
As a side note, my NK cell function was high normal or slightly high even when I was bedbound and housebound, so normal (or high) NK cell function is no guarantee of a remission.
