    The immune system is made up of many interdependent cell categories such as cells, proteins, tissues, and organs that work together to protect the body. Several of these cell categories partake in a particular function. “The cells of the immune system can engulf bacteria, kill parasites or tumor cells, or kill viral-infected cells (The Immune System and Primary Immunodeficiency, n.d.)”. The immune system is a great teamwork among cells and proteins that work together to deliver defend against infection. The cells and proteins are not just one organ like the liver and the heart. The immune system is spread throughout the body to deliver a quick reaction to infection in the body. Cells are in our bloodstream and that’s how they travel throughout the body. The immune system is made of many different organs to protect the body.…

    The role MHC class II plays on the immune system is that some of its genes code for proteins that will be expressed on the surface of the immune system cells. Peptides which are protein fragments outside the cells will allow these proteins to be attached to them, if these proteins are recognised by the immune system as foreign (such as viral and bacterial) the MHC will send a signal to the immune system to trigger an immune response against the invading bacteria or virus.…

    Foreign antigens are phagocytized by a macrophage and parts of it are presented on the macrophage’s cell membrane, along with the macrophage’s self antigens. Helper T cells encounter the macrophage and see both the self and foreign antigens for comparison. This causes the helper T cells to become sensitized to and specific for the foreign antigen.…

    2.2) Antimicrobial peptides are usually produced as inactive propeptides that require cleavage by a protease to complete their activation, often by generating a cationic peptide that takes on an amphipathic structure capable of disrupting the cell membrane of a microbe. Also in neutrophils the antimicrobial agents are activated by proteolytic cleavage when these granules fuse with phagosome and encounter neutrophil elastase that has been released from primary granules. Paneth cells and neutrophils control the release of the proteases responsible for cleaving and activating these peptides.…
