  • 12Steps


DL-978: Immune System – The Cells and Cell Surface Molecules Elizabeth Crabb Breen, M.T. (ASCP), Ph.D. - David Geffen - School of Medicine at UCLA Approved for 3.0 CE Level of Difficulty: Basic CAMLT is approved by the California Department of Public Health as a CA CLS Accrediting Agency (#21) The immune system is not a single discrete organ or collection of tissues, located in one or a few anatomic sites. In fact, it could be considered two collaborative systems: the innate immune system that reacts in a relatively non-specific manner, and the adaptive (or acquired) immune system, capable of incredibly specific recognition and response (1). These immune systems are composed of a variety of tissues and cells types, both fixed and mobile throughout the body, that work together, first to try to prevent the entry of pathogens and/or foreign material (known as antigens) into the body. Failing that, the immune systems spring into action to recognize and respond to the presence of antigens in order to eliminate or neutralize them, especially those associated with microbial pathogens.
