FOR 40 POINTS WITH THE BEST ANSWER

1. Recently, researchers have demonstrated that the bacteria that causes Lyme disease alter dendritic cells. How do T-cells work to protect us from pathogens like the one that causes Lyme disease?

2. Why do you think it is beneficial for a pathogen to make its host very sick without killing the host?

3. If these patients were treated with antibiotics, what clue would this have given doctors about the disease’s pathogen?

4. It is a common misconception that the immune system cannot combat pathogens it has encountered before. Explain why that statement is not true.

5. Using your knowledge of non-specific defenses, how could someone prevent Lyme disease in the first place?

Answer:

1: Activated Cytotoxic T Lymphocytes (CTLs) , using the T-Cells receptor neutralize pathogens.

2:  The pathogens employ this technique to infect chronically and turn the host into a reservoir for further transmission and infection.

3: That the pathogens were bacterial in origin.

4: The body retains memory B Lymphocytes of previous infections. If the pathogen returns the memory B-Cells can mount a quick immune response.

5: By taking proactive measures such as, insect repellants, protective clothing, and other measures that prevent tick borne illnesses.

Explanation:

See Above

1. The T-cells sometimes works as :

  • "killer cells" by attacking the infected cells with a pathogen
  • "helper cell" which supports the B cells to help produce antibodies.

The activated Cytotoxic T Lymphocytes uses the T-Cells receptor to neutralize the pathogens.

2. The pathogen makes the host sick to infect chronically thus making the host a reservoir for more infection and transmission.

3. If the patients were treated with some antibiotics then the doctors would come to know that the pathogens were bacterial in origin.

4. Our body retains a memory of the B Lymphocytes of any previous infections. And if the disease causing pathogen returns this memory, then the B-Cells can mount for a quick immune response.

5. One can prevent a Lyme disease by :

  • proper clothing
  • using insect repellant
  • keep the area clean and moist free
  • prevent the spread of tick borne disease
