Antigens Presentation
There is mainly one type of antigen present in the Major Histocompatibility Complex (MHC). They are the Human Leukocyte Antigen (HLA). This is the main driving force of the Major Histocompatibility Complex (MHC). There are many types of HLA. In the MHC Class I, there are three types of HLAs. They are HLA -A, HLA -B & HLA -C. In the MHC Class II, there are also three types of HLAs. They are HLA -DR, HLA -DQ & HLA -DP.
The HLA helps to identify foreign elements. There are all types of cells inside the body. As MHC Class I is only present over the nucleated cells. So, there should be a recognition mechanism to find out the proper substance. The HLA does the same thing. It was first able to recognize the foreign element type. If the elopement is derived from the body, the proper HLA provides the signal to MHC Class I. If the element is not derived from the body, then the HLA provides the signal to the MHC Class II. Then they start their usual work there.
Major Histocompatibility Complex(MHC)
The immune system is the most essential system of our body. It not only helps to protect the creature from foreign substances. Also, it helps to grow up without any outside disturbance. The immune system protects us from various threats. It protects from various foreign substances. It identifies them & destroys them. so, that the animal can able to grow up without any issues. Sometimes it is assumed that Immune System is only made with the White Blood Corpuscles. But that is not a correct assumption. It is a complete system where different components & proteins play an important role. Major Histocompatibility complexes (MHC) are similar kinds of a substance.
