dante's page doesn't say anything about his physical abilities slowing down, but it does say that his hair has gone white with age and that "he's old, it shows". so it seems (though not definite proof) that dante isn't biologically immortal but is still subject to the process of senescence - cellular deterioration that comes with age.
