Dr. Mellman explains that the immune system is made up of specialized cells that protect us from the huge number of pathogens we continually encounter. The immune system has two "arms"; innate immunity which detects components shared by all pathogens and adaptive immunity which detects components specific to individual pathogens. Mellman explains how these two "arms" work and the important role of dendritic cells in linking the two "arms" together.
