Summary Introduction

To review:

The immune response on an encounter with a pathogen.

Introduction:

When a cell encounters a foreign particle, the immune response is generated. The immune response is of two types: a primary response thatis generated on the first encounter with the pathogen and secondary response that comes into work during the subsequent infection by the same pathogen. Secondary response is generated from the memory cells that remember the first encounter with a pathogen.
