5.4 FERMENTED MILK AND THE IMMUNE SYSTEM
5.4.1 OVERVIEW or Thu IMMUNE SYSTEM
A brief overview will help to clarify the different branches of the immune system involed in the response to LAB and fermented it constantly defense systems against the massive invasion of foreignmatter it constantly receives .The of this response depends on two factors:
l. The type of foreign particles
2. The route of entry
the first line of defense involves physical-chemical barriers such as the skin and the mucus layers, e.g. in the nose and intestines, which indeed prevent the occumence of most infectious diseases.
The immune system represents the second line of defense against microorganisms, and its response involves a complex interrelation of its various components.
The three principal steps in this response are:
1.Recognition of the foreign molecule
2. Destruction of the foreign matter
3. Regulation of the response through multiple feedback controls
