Pathogens Song

Flu Attack! How A Virus Invades Your Body

Immune System - Natural Killer Cell

 

Natural Killer Cells are the most aggressive white cells in the immune system. They make up about 5% to 15% of the total lymphocyte circulating population. They target tumor cell and protect against a wide variety of infectious microbes. Natural Killer Cells are a very important factor in the fight against cancer. Immune Stimulation is the key to keeping the white blood cell count high and giving the Natural Killer Cells a chance to fight cancer and other diseases.

The inmune system

http://www.innerbody.com/The immune and lymphatic systems are two closely related organ systems that share several organs and physiological functions. The immune system is our body’s defense system against infectious pathogenic viruses, bacteria, and fungi as well as parasitic animals and protists. The immune system works to keep these harmful agents out of the body and attacks those that manage to enter.

The human microbiome.

Some use “microbiome” to mean all the microbes in a community. We and others use it to mean the full collection of genes of all the microbes in a community. The human microbiome (all of our microbes’ genes) can be considered a counterpart to the human genome (all of our genes). The genes in our microbiome outnumber the genes in our genome by about 100 to 1.



The Microbiome And Disease

Doctors have long viewed microbes as things to be gotten rid of. Viruses, after all, give us measles and the flu. Bacteria cause strep throat and food poisoning. But most microbes do not make us sick. And many are important for our health (see Your Microbial Friends).
As researchers learn more about the microbes that keep us healthy, we are coming to understand how subtle imbalances in our microbial populations can also cause disease—and how restoring the balance may lead to cures. Our new understanding may lead to more focused and effective treatments. Unlike modern antibiotics, which kill good microbes along with the bad, new drugs may kill only harmful bacteria while leaving the friendly ones alone. Others may nurture friendly bacteria, helping them outcompete the harmful ones.​
