PPT-The Immune System: Innate & Adaptive Body Defenses

16 Chapter 21 Immunity Resistance to disease Immune system has two intrinsic systems Innate nonspecific defense system Adaptive specific defense system Immunity Innate defense system has two lines of defense. Zoran . Galic. Ph.D. .. Division of Hematology/Oncology. David Geffen School of Medicine UCLA. zgalic@ucla.edu. August . 11, 2015. In response to pathogens, vertebrate immune systems use two interconnected systems:. Chapter 16: Innate (nonspecific) Immunity. Some terms:. Susceptibility. : Lack of immunity to a disease.. Immunity. : Ability to ward off disease.. . . immunity. : Defenses against any pathogen.. Chaparral High School. What is immunology?. Very simply, it is the study of our body’s defense against infection and disease.. Even though we are constantly bombarded by microorganisms, we rarely become sick. Why?. Ligand. In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformation of the target protein.. Learning objectives. By the end of this session student will be able to. .

Vaccination is one of the most effective medical interventions to reduce morbidity and mortality of infectious diseases. The main principle of vaccination is the proactive induction of a protective immune response by mimicking the natural interaction of an infectious pathogen (bacteria, viruses, etc.) with the human immune system (Fig 1). catherine. . hartnett. The Immune System. Concept 43.1- In innate immunity, recognition and response rely on shared traits of pathogens.
