Transplant Memes

The immune system: simultaneously our greatest defender and most problematic roommate. Here we see immune cells celebrating their "victory" after destroying a transplanted organ that was actually trying to save the host. It's like hiring a security guard who tackles the pizza delivery person because "they weren't born in this house." Immunosuppressants exist for this exact reason - to tell these overzealous cellular bouncers to maybe chill for five minutes and let the new kidney do its job.
