Our knowledge and understanding of the various forms of lymphocytes continue to expand. Our initial discussion this week will be on the various forms of B and T cells — each of us should take one class of lymphocytes and explain it’s role in the adaptive immune process. As you comment on other students’ postings be sure to add additional insight into the mechanisms of the subclass of cell and its interactions with both components of the innate and other aspects of the adaptive immune system.
Recently a number of individuals have claimed that adjuvants, such as thymersol in vaccines, lead to the development of a variety of disorders, such as autism. Although these initial claims have not been substantiated and have since been withdrawn from the scientific literature, the concern continues today. How would you counsel parents concerning vaccination? Discuss the issue of herd immunity and the risks in our modern society related to refusal to provide vaccinations.
Answer
Lymphocytes are of two major types – T-cells and B-cells. To begin with, B-cells produce antibodies that fight viruses and bacteria (Saladin, 2020). Notably, the bacteria are Y-shaped and act by locking onto the surface of invading cells and marking it for destruction by other immune cells. On the other hand, T-cells are of two types – Helper T-cells and Killer T-cells. Helper T-cells stimulate the B-cells to make antibodies, thus, helping the killer cells to develop (Saladin 2020). Killer T-cells kill the cells that have been infected by …. To access full answer, click on the purchase button below.
