Around us, in the environment, there are many microbes that can harm our body, causing illness or even death. Our cells that defend us against these microbes are called immunocytes or white blood cells. The immunocytes are very important to protect our body. Like we defend our bodies, it is also very important to care the health of our soul. In this book I will show you the armor that protects the soul of our immunocyte Felix.

Human beings need to tolerate foreign molecules that benefit us, such as food or 'good' microbes. Learn how our T regulatory lymphocytes control our powerful immune army. A book for all ages

Since birth we are exposed to dangerous microbes than put our life at risk. So, we need several cells and molecules capable of defending our body. We will call "immune system" to our body defenses, and "immunocytes" to the immune cells that protect us. Some people have a vital organ or tissue severely damaged. They need a transplant to continue living. The immunocytes are very strong and powerful to attack bad microbes. However, they must tolerate foreign molecules in the transplanted graft. In this book we will learn about the importance of transplantation to prolong life in individuals with...
