In this article we will discuss about the properties of cytokines (explained with diagram). 1. Cytokines are a group of low-molecular- weight regulatory proteins secreted by WBC and other cells in the body. 2. Cytokine secretion is very specific and self- limited event as because they are not usually stored as performed molecules. Cytokine synthesis is initiated by new gene [...]

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 [...]
In this article we will discuss about the steps involved in cellular immune response. Host defenses that are mediated by antigen specific T-cells and various non-specific cells of the immune system is called cell mediated immune responses. Cellular immune responses have an activation phase and an effector phase. These phases occur as follows (Fig. 10.2): 1. A viral protein made [...]
