Introduction to IMMUNOLOGY
What is Immunology? What is Immune System (IS)?
Immunology is the study of our protection from foreign macromolecules or invading organisms and our responses to them. Foreign macromolecule/ Antigen –--- Immunogen: e.g. virus protein, worm, parasite Everything that should not be in my body

Immune System: Molecules, cells, tissues and organs which provide nonspecific and specific protection against Microorganisms; Microbial toxins and Tumor cells

Crucial to human survival

I. Experiential Immunology period
(the 17th century- the middle of 19th century)

In ancient times, many serious infection diseases, such as smallpox, plague and cholera etc, caused innumerable people dead.

The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350, and killing between 75 million and 200 million people Wikipedia Yersinia pestis

Large clusters of bacteria (arrows) are found in the alveolar spaces (top right, B), adrenals (bottom left, C), and kidneys (bottom right, D) [hematoxylin-eosin, original × 400].

II. Experimental Immunology period
(the middle of 19th century-the middle of 20th century)

1. Active immunity
In the middle of 19th century R. Koch ----Isolated and cultured bacteria successfully Pasteur ----Infectious diseases were caused by pathogens In 1880, Pasteur ----Anti-cholera live-attenuated vaccine (old culture of Chicken V. cholera) ----Artificial active immunity
