5. Blood Cell Star Wars

Step aside, Star Wars - there’s a whole new force in town, and it’s coursing through our veins to keep us safe: White blood cells, particularly antigen-presenting cells, act like intergalactic warriors by displaying antigens from invaders on their surface receptors. This allows them to communicate with fellow immune cells, rallying the troops to launch a coordinated counterattack on any pesky pathogens that dare trespass into our bodily realms.

7. Pregnancy and Th17/Th2 Cells

It's all about balance, baby: just ask the Th17/Th2 cells in a pregnant woman's immune system! These multitasking T helper cells know how to get the party started by producing IL-4 and IL-17 while keeping any rude crashers (like Th17/Th1 cells) at bay. The happy result: a harmonious Th2-type environment that fosters a healthy pregnancy while telling risks of autoimmune complications and recurrent abortion to hit the road, Jack!
