  • Antibiotic Resistance Case Study

    Briefly describe the life cycle of the HIV virus. The HIV virus enters the cell and is able to replicate by: binding and fusing to T-cells receptors, using the enzyme reverse transcriptase to change the genetic material so it is able to enter the DNA of the host, integrating by entering the nucleus of the T-cells and using the integrates enzyme to integrate itself into the genetic material, transcribing to create more genetic material and longer proteins, assembling by using protease enzymes to cut HIV proteins so they are able to come together with the virus’ genetic material and assemble the new virus, and finally by budding the virus pushes itself out of the cell with part of the membrane so it is able to bind to additional T-cells and duplicate the process (AIDS.gov, 2009). HIV sometimes starts with an acute infection called acute retroviral syndrome (2-4 weeks after the individuals is infected) in which the infected individuals may feel flu like symptoms and large amounts of HIV starts being produced within the body. The virus then uses T-cells, which are vital immune system cells, to make copies of itself and destroy cells; T-cell count falls drastically. During the latent period of HIV, T-cell counts slowly drop at first and then eventually start dropping more drastically again, making the person less able to fight off diseases and infections; HIV eventually turns into AIDS (i.e. T-cell count below 200 cells per cubic millimeter) in which the infection has spread and…

  • Having Hiv/Aids Hardship

    This causes them to be tired and have a lack of energy (Lederal, Gay, Aouizerat, Portillo, Lee). These symptoms could interfere with their daily activities and self care. There fatigue does not go away with a good rest of sleep. It is a constant battle of exhaustion for them. Some researchers found that people who have a lower CD4 and T-cell count are at a higher increase for fatigue (Lederal, Gay, Aouizerat, Portillo, Lee). Because these people have chronic fatigue, they could have disturbed…

  • T Cells Essay

    The T cells are a type of white cells, which are important to the immune system, and contain a system that adjusts the body’s reaction to specific pathogens, this being the center of its adaptive immunity. T cells are like soldiers who search out and destroy the targeted invaders. T cells can be compared to soilders, they search out and demolish intruders. There has been a literature attention on the function of the administration in cancer immunity in T-Cells. The T cells are now known to take…

  • Hashimoto's Thyroiditis Case Study

    patient (Fisher, 2014). Using the Theory of Planned Behavior, the psychologist will be able to point out actions to the patients and family to examine what behaviors are having a negative and positive effect. Once examined, the information gathered could be used to make an effective change. (Rich, 2015). Hashimoto’s has a very limited research history. There is no cure. There is only a limitation of symptoms (Bishay, 2016). An old method of research was into B lymphocytes and it examined the…

  • Characteristics Of Treg Cells

    that Treg cells produce forkhead box protein 3 (Foxp3) at some point of their development. This protein is an important molecule in immune regulation as its presence in cells was determined to be sufficient in the suppression of proliferation and cytokine secretion by effector cells. Furthermore, a frameshift mutation in Foxp3 results in a fatal syndrome of extensive immune activation, leading to the over secretion of numerous cytokines and multi organ infiltration by inflammatory cells…

  • Interleukin 4 Lab Report

    to a mouse protein called B-cell stimulatory component 1 (BCSF-1). Cytogenetic Location: 5q31.1 Molecular Location on chromosome 5: base pairs 132,673,986 to 132,682,678 (Homo sapiens Annotation Release 107, GRCh38.p2) The IL4 gene is located on the long (q) arm of chromosome 5 at position 31.1. IL-4 has been known as the "prototypic immunoregulatory cytokine." Takes an interest in no less than a few B-cell enactment forms and of other cell sorts. It is a…

  • Natalizumab Case Study

    T cells also have effect on Natalizumab in patients with multiple sclerosis. Natalizumab is a monoclonal antibody that reduces the formation of acute lesions in the central nervous system. Bornsen et. al revealed the influence that natalizumab has on circulating CD4+ T cells in multiple sclerosis. The recurrence of multiple sclerosis happens when there are abnormalities in activated macrophages, CD4+ and CD8+ T cells in the central nervous system. Very-late antigen formed on surfaces of most…
