Initial Post Instructions
Your friend Bruce calls in a panic. He has just come from the doctor and been diagnosed with a bacterial infection. The doctor told him not to worry; his B cells will take care of it in no time! Knowing that you are studying the immune response, he is calling to ask you to explain this statement. Is the doctor correct? Is there more to the story?
Initial Post
Regarding the diagnosis of Bruce’s bacterial infection, the doctor said the right thing by telling his patient not to worry. Lymphocytes are the second most common white blood cell in the blood, comprising 20% to 35% of the total circulating leukocytes; B lymphocytes, and T lymphocytes (Cowman, 2020). B cells produce antibodies by recognizing pathogens that carry antigen receptors and capturing them through their B cell receptors. The consumption of bacteria diffuses them and creates protection as the immune response as it could also trigger other immune defenses. These foreign substances become stimulated which trigger Bruce’s cells, therefore the lymphocytes become activated. In order for this process to occur, B cells first rely on T cells to recognize the antigen outside of the infected cell through protein interaction between both cells. T cells develop in the thymus and B cells develop in the bone marrow, both working together to fight bacteria and viruses that enter the body through portals of entry.
