Mission Infection

Human body is not just populated by the cells; it has a lot of beautiful sceneries too.

It has tall, trees and small bushes in the form of cilia, flagella and microvilli.

It has tall mountains formed by epithelial cells in almost every organ. It has big rocks and small stones in the form of proteins. It has beautiful roads, routes, paths and detours in the form of blood vessels, capillaries, arteries and veins.


If you could imagine our body has roads too, in the form of blood vessels in the all the organs, and the white blood cells army is constantly on parole for the thieves and the robbers in the form of pathogens through the capillaries , arteries and veins . If they come across any pathogen on the road they kill them in the encounters. If pathogens attack in large numbers then the white blood cells declare battle against them and fight united with those dreadful pathogens that cause diseases in the organs of the body.Red blood cells on other hand are a big chain of suppliers, the deliver food home to every cell from the restaurants called heart and stomach. They make sure the cells from different organs are fed properly with the oxygen and keep all the cells in all the organs happy. Among the white blood cells, the T cells are equipped with the swords in the form of CD4 and CD8 T cell receptors, T cells are like a sword fighter soldiers that use T cells receptors as a swords to kill the pathogens. The B cells are archers that fire different type of antibodies from their repertoire depending on type of the pathogens. They shoot the antibody arrows from their crossbow and kill the pathogens.

Mast cells on other hand are big USPS postal service; they send messages to the white blood cells and keep them updated with the information about casualties, accidents, attacks on the cells from different organs of the body.Macrophages are gourmets, some sort of eating machines; they like meat of the pathogens and they devour any kind of pathogen they see.

 

Along with beautiful greenery, body has arid lands too, In the skin where there is less blood cells population and more marshy area of sebum and the dead cells, the pathogens are frequent in the skin area and the small kid blood cells are prohibited visiting there for the security reasons.

 

And guess what, like humans sometimes these cells play politics between themselves for the same reasons we human play politics.  Greed, jealousy, ambition, love and betrayal touches these cells too and when it happens our body suffers. These cells sometimes forget about their duties and trouble their mates and the evil pathogens – the terrorists exactly take advantage of such politics to infect the organs, spread their terror and cause diseases to the body,

 

Okay, now having peeked into the beautiful and dangerous world of blood cells in our body let me tell you a story of a small CD8 T cell that lives in the thymus. He is lovable, innovative, very cute young lad but at this small age he has to go thought a lot. At this tender age, he gets tormented by his own cells. Rejected by the cellular citizens, the terrorist pathogens make him hostage but he doesn’t deter or flinch against such difficulties in life. He is often alone during his trials but this time around he is accompanied by his silly funny friend. he embarks on the journey of self discovery in the body. On the way he meets one mentor, an angel who teaches him his job, makes him aware of truth of the cellular life, he makes him realize his duties, give his courage to fight against bad cells and terrorists pathogens like HIV viruses, and finally after a roller coaster ride he establishes his identity, earns name for himself in the big bad world of the human Body.
