What is the Difference between Immunoglobulins, T Cells, Antibodies and Antigens
Immune system in the living organisms is responsible for protection against diseases. In fact, the function of the immune system is to identify neutralize harmful bacteria and viruses by means of antibodies. We can say that when the immune system becomes week in the human body, the body is attacked by various diseases. The reason is that, there remains no resistance in the body against harmful bacteria and viruses. Immunoglobulins, T Cells, Antibodies and Antigens all are the names of immune system parts that strengthen the function of the immune system in the body. If you want to know the difference between Immunoglobulins, T Cells, Antibodies and Antigens, this is the right piece of writing for you.
Immunoglobulins
Immunoglobulin (Ig) or surface Immunoglobulin is the membrane-bound or soluble form of antibody. The special feature of surface Immunoglobulin is that, it contains trans membrane region which binds it to the membrane of B cell receptor. This then enables the B cells to identify and resist against harmful viruses itself.
T Cells
T cells which are also known as T Lymphocytes which play a vital role in cell-mediated immunity are a member of white blood cells. The T cell Receptor (TCR) distinguishes the T cells from other commonly known lymphocytes such as natural killer Cells and B cells. Thymus which is the special organ of the immune system is responsible for the growth and direction of T cells for their specified task. Some famous types of T cells are Helper, Cytotoxic, Memory and Regulatory.
Antibodies
The function of antibodies is very clear and famous in the living organisms. The first thing, without antibodies, the immune system is nothing and it means there is resistance in our body against the diseases caused by harmful bacteria and viruses. An antibody is nothing but a protein of Y-shape which is secreted from B cells. There is no trans membrane region available in antibodies which enable them to float into the blood stream and body cavities.
Antigens
Antigens are also an important part of our immune system which recognizes the number of required antibodies in our immune system. An antigen is also a protein based substance which is responsible for the formation of one or more antibodies by entering your body.
Immunoglobulins vs T Cells vs Antibodies vs Antigens
The separate functions of antibodies, antigens and T cells are crystal clear in front of many people. We can shortly define all these terms as an antibody is the substance which is responsible for identification and neutralization of harmful bacteria and viruses. However, an antigen is responsible for the production of antibodies instead of T cells which destroy infected cells in the human body. However, the difference between Immunoglobulin and antibody is that, Immunoglobulin is also a type of antibody but with trans membrane region which is not available in antibodies.
