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.
I mean the preferance in chirality for organisms was something mentioned in organic chem classes so it is interesting we might actually make the other type. I would be more worried about the proteins themselves acting like prions or such. I mean I doubt our cell structure would replicate it but you never know what the interactions are going to act like.
