    The human immune system consists of multiple structures. These structures include the following: tonsils and adenoids, thymus, lymph nodes, spleen, appendix, lymphatic vessels, and bone marrow. HIV involves many structures/components of the immune system, so it is important to understand the structures and function of each involved component. Calles, Evans, and Terlonge (2010) clearly explain the parts of the immune system affected by HIV. To begin the immune system uses antigens to help fight

    Sepsis Sepsis is a systemic over response of the immune system, due to an infection that the body tries to fight. This leads to reduced blood flow to vital organs such as the kidneys and the heart, which often results in multiple organ failure with the possibility of death. Sepsis can develop into septic shock which is the point where the patient’s blood pressure drops to a dangerous level due to the presence of bacteria in the body. Patients diagnosed with sever sepsis have a 20-30% chance of death

    The innate immune system is your body’s first line of defense against foreign pathogens. It consists of both physical and chemical barriers. Foreign pathogens that are found in the body have patterns on them that allow the body’s immune cells to identify it. These are called pathogen-associated molecular patterns (PAMPs). The host cells use special receptors called pattern recognition receptors (PRRs) that recognize PAMPs. With the pathogen identified, it can be tagged for Phagocytosis. The pathogen

    INTRODUCTION In order to provide a detailed analysis of recent pharmacological developments involving the human immune system, it is firstly necessary to introduce the innate and adaptive immune responses . Immunosuppressants and immunomodulators will be differentiated between and a selection of new and often experimental drugs belonging to each category will be provided. Specific drugs will be described including the pharmacokinetics and pharmacodynamics involved with each type. The possible clinical

    The trouble for fully understanding their roles thoroughly stems from the “nontemplate nature of their synthesis.” This paper calls attention to what is known about the different binding partners of carbohydrates and their cooperation within the immune system, namely microbial (non-self), tumor (altered-self), and host (self). DNA and RNA can be thought of as polysaccharides with phosphate-linked polyribose cores. Without carbohydrates present, it would be impossible for them to form the scaffolding

    The immune system contributes to homeostasis as it protects and defends against invaders that pose a threat to the body’s balance. Homeostasis is an internal balance that is maintained by multiple factors within the body. The immune system is responsible for avoiding and limiting infections in the body. It prevents and heals damage that invading pathogens may cause to the body. In this way, it helps maintain homeostasis by eliminating pathogens and the imbalances they cause in the body. A first defense
