Why should it be? Because of lacking relevance? The community can find even research in mice interesting - look just how much debate has this topic produced here. We're not an Alzheimers research forum, we are a bunch (tribe? murder?) of nerds who like to gab about new things.

You'd have a better point if the "in mice" was hidden somewhere in the text - for subtle dishonesty, but as long as the title admits it openly, I don't see a reason to flag the submission in itself.
