In this lecture we will discuss about difference between innate and adaptive immunity. We will discuss about definations, components,mechanism,resistance,response to pathogens,secreted proteins and key features in pathogen recognization of both innate and adaptive immunity

Innate immunity
immunity with which an organism is born. It consists of following components
1.neutrophils
2.Macrophages
3. Monocytes
4.Dendritic cells
5.Natural killer cells
Innate immunity is germ line encoded and resistance persists throughout the lifetime and from generations to generations.its response is non specific and quick with no memory.It contains antimicrobial secreted proteins and have toll like receptors to recognize PAMPs on pathogens and activate NF-KB 

Adaptive Immunity
it is an adaptive and specific immunity having T and B lymphocytes and circulating antibodies as components
it has variation through V(D)J recombination and microbial resistance is not heritable.It is highly specific and first response is delayed response but second response is quick and strong
it has immuniglobulins as secreted proteins
it has memory cells for 2nd quick response
