The Immune System Overview and Tutorial - Innate and Adaptive

http://www.anatomyandphysiologyquizzes.net/

Hey everyone, this is a tutorial on the immune system which covers both the innate and acquired immune system.

Innate Immune System
1. PRRs located on neutrophils, mast, macrophage, dendridic recognize PAMP
2. Release of cytokines especially IL-1 and TNFa which act on post-cappiliary venule endothelial cells
3. This leads to adhesion molecules, vasodilation and exudate
4. Adhesion molecules: "chemotaxins" IL-8, C5a, LTB4, cause rolling of leukocytes on endothelial cells, adhesion, and migration to pathogen
5. Tissue damage releases eicosanoids: prostaglandins PGI2, PGE2 (vasodilation) and leukotriene LTB4
6. Opsonins created from complement cascade: C3b
7. Cytokines stimulate synthesis of vasodilator nitric oxide, increasing vascular permeability.

For the acquired immune system, I go over how antigen presenting cells work in combination with T lymphocytes helper and T lymphocyte cytotoxic cells.

I am also wondering if you could put up a link to the diagram? I found it very helpful!!

Is there anyway you could email the diagram to me? I have to do a presentation for school and you nailed the summary down quite well. I just want to review it on paper and make notes.
