Question

Immune System

Choose ONE of the scenarios and explain what the immune system is doing. Your explanation should be 7 – 10 complete sentences. Diagrams/drawings might be helpful.  

In your description, correctly use, at least 8 of these vocabulary words:

Adaptive/acquired immune response	Antibody	Antigen	Cytotoxic T-cell	Fever
Helper T-cell	Histamine	Inflammation	Innate immune response	Macrophage
Mast cell	Memory B-cell	Natural killer cell	Neutrophil	Pathogen
Plasma B-cell	Pus

Scenario A: A patient comes in with symptoms of fever, loss of appetite, a sore throat. You, the doctor, think that it might be a bacterial infection and prescribe antibiotics. The patient takes the antibiotics however the symptoms do not go away. What is the patient’s body doing to fight the disease?

Scenario B: You are hurrying to finish working with some wood to make a paper weight. A splinter from your masterpiece ends up in your hand. You pull the splinter out, but late that night, your finger becomes swollen and red. A few days later the entire hand is swollen, the pain is intense, and you develop a fever. What is going on?

Scenario C: You find out that one of your ancestors had leprosy, caused by the Mycobacterium leprae bacteria. The relative worked in a leper colony for 25 years in what is now Hawaii. The relative did not develop leprosy until soon before leaving there. What does the body do to fight the bacteria?

Write your paragraph here (some sentences provided if you want them):

In scenario ______ the symptoms indicate that the immune system is working in the following way ...

Answer 1

Scenario A: A patient comes in with symptoms of fever, loss of appetite, a sore throat. You, the doctor, think that it might be a bacterial infection and prescribe antibiotics. The patient takes the antibiotics however the symptoms do not go away. What is the patient’s body doing to fight the disease?

During a bacterial infection, the body is initially attempting to fight using the innate immune response. The innate immune system contains many different defense mechanisms such as neutrophils, macrophages, cytokines, and the complement system. These components of the innate immunity will attempt to control the bacterial infection through inflammatory processes such as fever, muscle pain, and pus while the adaptive immune system can slowly develop a pathogen-specific response. This process can take multiple weeks after the initial exposure to the pathogen. Once the pathogen-specific antibodies are produced by B cells, they can begin their humoral response in the blood, tissues, and even secretions. Similarly, once T cells have been activated, they will exert their function. Helper T cells generate cytokines to modulate the immune response and Cytotoxic T cells actively kill the pathogen. However, it's important to note that Cytotoxic T cells play a major role in neutralizing viruses and cancer as opposed to bacterial infections.
