CD8 T cells proliferate and initially differentiate into which type of lymphocyte?

Correct Answer: Cytotoxic T lymphocyte (CTL)
CD8 T cells proliferate and progressively differentiate into Cytotoxic T lymphocytes (CTLs). The proliferation of CD8 T cells require repeated encounters with antigens. This antigenic stimulus triggers the developmental process and hence it causes differentiation of CD8 T cells. As and when the entire developmental process is completed by committing CD8 T cells to differentiate, they activate Tumour-necrosis factor and kill infected cells. 

Which of the following statement(s) is/are CORRECT for antigen activated effector T cells?
P. CD4+ cells make contact with macrophages and stimulate their microbicidal activity.
Q. CD4+ cells make contact with B cells and stimulate them to differentiate into plasma cells.
R. CD8+ cells make contact with B cells and stimulate them to differentiate into plasma cells.
S. CD8+ cells make contact with virus infected cells and kill them.

Lineage commitment is a process in which CD4–CD8– (double negative) thymocytes differentiate to CD4– and/or CD8– T cells. 

T cells proliferate and differentiate into which of the following cells on receiving primary response?

Which of the following statements are correct regarding common differences between plant and animal cells?
1. Plant cells have cellulose cell wall, while animal cells lack it.
2. Plant cells lack plasma membrane, while animal cells have it.
3. Mature plant cell have a large vacuole, while animal cells have numerous small vacuoles.

The cells which have the capacity to divide and differentiate into any type of cells in the body are the focus of research of several serious diseases are

Consider the following statements and choose the correct answer:
1. All living things are composed of cells and their products
2. All cells arise from pre-existing cells
3. All cells are basically alike in chemical composition and metabolic activities
4. The function of an organism as a whole is the outcome of the activities and interactions of the constituent cells

What is the ratio of CD4+ cells to CD8+ cells?

Select the four statements about Plasmodium that are true. A)Inside an infected mosquito, haploid gametes fuse, forming a diploid zygote that develops into an oocyst B) Plasmodium cells infect two specific types of cells in humans. C) Inside an infected mosquito, haploid gametes fuse, forming a haploid zygote that develops into an oocyst. D) When a mosquito bites a human with malaria, diploid Plasmodium cells enter the mosquito. E) Plasmodium cells are transferred to humans through mosquito saliva. F) The life cycle of Plasmodium involves only haploid forms. G) The complete life cycle of Plasmodium requires two hosts.

MZ B cells differentiate in which type of cells?

Mesenchymal stem cells are multipotent stromal cells that can differentiate into a variety of cell types.
