In this article we will discuss about the features of adaptive immune responses. 1. Specificity: It ensures that distinct microbes elicit specific responses. It exists because individual lymphocyte expresses membrane receptors that are able to distinguish subtle differences in structure between different antigens. 2. Diversity: It enables immune system to respond to a large variety of microbes. The total no. [...]
The upcoming discussion will update you about the difference between active immunity and passive immunity. Difference # Active Immunity: 1. Host participation: Produced actively by the immune system of host. 2. Activation: Induced by infection or by contact with immunogen. 3. Duration of effectivity: Immune response-durable and effective. 4. Time: Immunity effective only after lag period. 5. Memory: Immunological memory [...]
The below mentioned article provides notes on immune system. Immune Response: Any foreign protein, toxin of parasites, bacteria and viruses, when enter into the body, they interfere with host physiological processes and produce harmful effects. The "Chemical defense" mechanism of host organism that operates against such effects of parasites and others is called immune reaction or immune response. Immunology: The [...]
