Course Description
Immunology is a fascinating, but complex and rapidly changing field. In this course, the general introduction will provide cells and organs of the immune system; the different components of immunity; and receptor and signaling. A concise overview and analysis of the immune defense against infectious diseases and parasite escape within host will be presented. Special attention will be given to the various components of the immune system that play a role in the induction of innate and adaptive immunity against infectious diseases. Finally, infectious disease and vaccine will be highlighted.
Course Objectives
At the end of the course, students will be able to:
§ Describe the structure and function of cell and organs of the immune system and its components;
§ Provide an overview of the types of cell interactions and molecules required for specific immunity;
§ Distinguish the most important immunological features relating to the major vector borne infections of man;
§ Describe the basic principles of host immunity to infection against the diverse range of pathogens which confront human populations;
§ Describe the mechanisms that the parasites escape within hosts; and infectious disease and vaccine.

Teaching Methods
Ø The course will encompass specific facilitator inputs (e.g. Lecture presentations), combined with a variety of interactive learning activities, including: structured group work, group and individual reflection, self-study and writing and plenary discussions. Each student will be required to conduct a bibliographic search on a specific topic chosen among the proposed topics, and write a report (5-6 pages, single space). Toward the end of the semester, each student will make a power point presentation that would lead a discussion.
