9 Uveitis and Ocular Inflammation
Chapter 1: Basic Concepts in Immunology: Effector Cells and the Innate Immune Response
An immune response is the process for removing an offending stimulus. The clinical evidence of an immune response is inflammation.
The immune system is composed of cells, tissues, and molecules that mediate response to infection or foreign material.
Immune responses are defined as innate or adaptive.
Innate (natural) immunity provides immediate protection and requires no prior contact with the foreign substance or organism.
Adaptive (acquired) immunity develops more slowly but provides more specific defense against infections, having a permanent cross talk with the innate immune system.
