Sooooo... Mirror cells can't be latched onto by normal cells. Why would mirror cells be able to latch onto normal cells? This seems like fear mongering because, logically speaking, if A can't attach to B, then B can't attach to A. I suppose you could program mirror cells to attack normal cells via indirect means (creating toxins that kill normal cells), but it seems like they'd struggle to fulfill their purpose because the article makes it sound like their "diet" is also mirrored.
