Unscramble the Blue Letters

A group of lymphocyte clles called T-cells go in search of infected body cells and swiftly kill them off. Meanwhile, B-cells and helper T-cells use the information gathered from the unique anengtis to start producing saceipl proteins called antibodies. This is the pcèie de résistance: Each aeigtnn has a unique, matching antibody that can latch onto it like a lock and key, and destroy the invading cells. B-cells can produce millions of these, which then cylce through the body and attack the invaders until the worst of the threat is neutralized.

Original Text

A group of lymphocyte cells called T-cells go in search of infected body cells and swiftly kill them off. Meanwhile, B-cells and helper T-cells use the information gathered from the unique antigens to start producing special proteins called antibodies. This is the pièce de résistance: Each antigen has a unique, matching antibody that can latch onto it like a lock and key, and destroy the invading cells. B-cells can produce millions of these, which then cycle through the body and attack the invaders until the worst of the threat is neutralized.
