Wouldn't it be cooler if Voyager's Holo Dokter would say: "I'm trying a tailocin based anti Nano-probe cocktail" instead of "synaptizine" or something fictional.
I'd be willing to do some consulting for these shows ;)
Who wants to build a site where we can post these ideas and script writers can buy these little cool snippets?
"The story takes place inside the human body, where trillions of anthropomorphic cells each do their job to keep the body healthy. The series largely focuses on two such cells; a rookie red blood cell, AE3803, who often gets lost during deliveries, and a relentless white blood cell, U-1146, who fights against any germs that invade the body."

And ultimately, these snippets are just filler that add background to the world in question. To people who aren't you, or me, they do not matter all that much.
It seems that we're learning how to turn human cells into software-defined factories, but I have no idea how complex the products can be.
Using a "live" phage also has the advantage that it would coevolve with the pathogen, the mRNA produced tailocin is always the same and the pathogens would probably become resistant quickly.
