Third Line Of Defense: Go hard or go home!
Components of the third line of defense and the roles that they play
MHC Recognition
The Major Histocompatibillity complex or MHC, is a group of genes that create MHC class markers which signal to other immune-system-related cells that something isn't right. Different types of mhc markers result in reactions from different cells.
Lymphocytes
Lymphocytes are a type of white blood cell that figure out how the immune system should respond to the threat. These cells are usually located in lymph nodes, tonsils and the spleen.
Antibodies
Antibodies are proteins in the blood produced to fight off a specific foreign body by identifying its antigen and then neutralizing them.
adaptive or acquired immunity
Adaptive/acquired immunity is an immunity that is developed after conception in a number of different ways. It can be received as a fetus/infant both through the umbilical cord and the mother’s colostrum, by fighting off diseases and surviving long enough to develop an immunity to said disease, or by having serums injected or taken-orally with the necessary antibodies or a weaken dose of the disease so that the body can develop an immunity.

Tc cells
T Cytotoxic cells are the big guns of the immune system; they target virus-infected cells and tumour cells. The TC cell finds its targets by looking for antigen-related MHC.
Th cells
T Helper Cells are T cell variations that assist other cells in different ways.
They alert Cytotoxic T cells and Macrophages, and aid white blood cells to create B memory cells and plasma cells. T helper cells themselves are activated when the cell comes into contact with an APC, this triggers the T helper cell to divide rapidly and release cytokines into the surrounding area.
Tm cells
T Memory Cells make up the body’s database of previous threats. When a threat is defeated, the T memory cells make a note of what the threat was, how it looked and how it was defeated. With this knowledge, the body can develop immunity to certain diseases and increase its defences.
Ts cells
T Suppressor cells are designed to shut down T Cytotoxic cells to prevent excess damage to the body.
TNK cells
T Natural Killer Cells are not the same as plain Natural Killer Cells.
These cells are capable of roles supplied by both Tc and Th cells, both cytokine secretion and cytotoxic assaults.
B cells
B cells come in insurmountable numbers, each one designed to react to different antgens. When a b cell binds to the antigen it was created to target, It duplicates rapidly to create a large amount of Plasma cells.
Plasma Cells
Once created by B cells, the plasma cells release a large amount of antibodies to kill the antigen that triggered the plasma cell’s creation.
