Differences: Humoral and Cell Mediated Immune System | Biology

The upcoming discussion will update you about the difference between humoral immune system and cell mediated immune system. Differences # Humoral Immune System: 1. The humoral immune system consists of B-cells, which originate in the bone marrow and mature in the bone marrow. 2. B-cells can produce antibodies, but need exposure to foreign antigens to do so. 3. Antibodies are [...]

Specific Defense Mechanism in Human Body | Immunology | Biology

Specific defense mechanism is the ability of the body to develop immunity against specific pathogens, toxins or foreign things. This is possible by a special immune system that produces antibodies and/or activated lymphocytes that attack and destroy specific invading organisms or toxins. Specific defense mechanisms are also referred to as adaptive or acquired immunity (Table 1). Organisms that possess an [...]

Structure of Immunoglobulins (With Diagram) | Immunology

In this article we will discuss about the structure of immunoglobulins, explained with the help of a suitable diagram. Identification of antibodies in the serum protein fraction was demonstrated in the classic experiments of A. Tiselius and E.A. Kabat in 1939. However, the basic structure of —globulin molecule was revealed by Rodney R. Porter and Gerald Edehman in 1950s and [...]
