Learning Objectives

• Identify the basic components of the immune system and their function: immune cells versus other mediators (eg. Ab, complement, cytokines)
• Distinguish between innate and adaptive immune responses: what makes them different?
• Identify the role of antigen presenting cells, lymphocytes, and phagocytic cells in immune responses
• Differentiate between humoral and cell mediated immunity

Innate & Adaptive Immunity

• compare properties of the innate vs adaptive immune responses?
• what are the 4 levels of defence against infection?
• what are the functions of the complement system?
• what initiates each of the 3 complement pathways?
• what are the consequences of complement deficiencies? - III week 12

Antigens & Antibodies

• what are antigens (Ags) vs antibodies (Abs)?
• what are the 4 key functions of antibodies? - III week 2
• describe the structure of antibodies?
• what lymphocyte type produces antibodies?

Immune Response Initiation

• why do immune responses take on a bell shape?
• how are immune responses triggered?
