18 Questions
What type of immune response is involved in the rejection of foreign tissue recognized as non-self by cytotoxic T cells?
Cell-mediated immune response
Which cells can also present antigens on MHC I to activate cytotoxic T cells?
Dendritic cells
What type of antigens can induce B cell recognition and activation without involvement from T cells?
T-independent antigens
What is the role of an activated TC cell in the immune response?
Causes apoptosis of the infected/affected cell
Which immune response is mounted against exogenous pathogens by B cells?
Antibody immune response
Which type of immune response specifically activates in response to particular pathogens?
Cell-mediated immune response
Which type of T cell has a CD4 receptor and is responsible for orchestrating both humoral and cellular immunity?
Helper T cells
What is the primary difference between B cells and T cells in terms of antigen recognition?
B cells can bind directly to antigens, T cells cannot
What is the primary function of natural killer (NK) cells in the immune system?
Participate only in innate immunity
Which type of T cell has a CD8 receptor and is responsible for destroying cells infected with intracellular pathogens?
Cytotoxic T cells
What is the primary function of regulatory T cells in the immune system?
Prevent autoimmune responses
Where are B lymphocytes (B cells) primarily found in the body?
Lymph nodes
Which of the following statements about memory cells is correct?
Memory cells are produced by B cells and T cells during the primary immune response and can rapidly respond to subsequent exposures to the same antigen.
Which of the following statements accurately describes the role of cytokines in the immune response?
Cytokines are soluble regulatory proteins secreted by leukocytes that function as intercellular signals to relay messages among cells of the immune system.
Which of the following statements accurately describes the process of antigen presentation?
Exogenous antigens are presented on MHC class II molecules by APCs after phagocytosis and processing, while endogenous antigens are presented on MHC class I molecules by infected cells.
Which of the following statements accurately describes the role of T helper cells (TH cells) in the immune response?
TH cells orchestrate both humoral and cell-mediated immune responses by binding to antigens presented on MHC class II molecules.
Which of the following statements accurately describes the role of B cells in the immune response?
The major function of B cells is the secretion of soluble antibodies to target, inactivate, and neutralize extracellular antigens.
Which of the following cell types can function as an antigen-presenting cell (APC)?
Macrophages, dendritic cells, and B cells
