The HIV research in a way could cure MS. HIV is a retrovirus and there are some hypothesises which state that MS is caused by a retrovirus. Any defeat of HIV would help MS if MS is caused by a retrovirus. This is very good news for people who suffer from other retroviruses.
Ah, but there's the rub. Over the years I've heard so many, it may be this, or it may be that, as to the cause, and still nobody has a solid lead on it.
