Which type of dendritic cells are considered to be perfect for cross-presentation?

Correct Answer: cDC1
Dendritic cells (DCs) are divided into two major categories: conventional DCs (cDCs) and plasmacytoid DCs (pDCs). Conventional DCs are again further classified into cDC1 and cDC2. In vivo, in humans and mice, it is observed that cDC1 plays a very important role in the cross-presentation mechanism and hence this DC subset is considered to be potent and perfect for cross-presentation of antigens.

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.

Which of the following statements about immune response are correct?
P. T cells are activated by antigen-presenting cells.
Q. Foreign peptides are not presented to helper T cells by class II MHC proteins.
R. Dendritic cells are referred to as professional antigenpresenting cells.

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.

NK cells act as regulatory cells to influence the actions of dendritic cells.
