Humoral immunity
Which type of immune response is effective against extracellular microbes and their toxins?
Humoral immunity
Which cells are involved in mediating cell mediated immunity?
T helper 1 (Th1) cells
What is the role of T cytotoxic cells in the immune response?
Killing infected cells directly
Which type of immunity involves the production of immunoglobulins or immune cells for protection?
Artificial passive adaptive immunity
Which type of immunity is particularly effective against viruses and intracellular pathogens?
Cell mediated immunity
What is the main function of B cells in the adaptive immune response?
Produce antibodies for humoral immunity
Which type of immune cells specifically recognize antigens attached to MHC proteins on the surfaces of other cells?
Cytotoxic T cells
What is the role of regulatory T lymphocytes in the immune response?
Suppress immune response
Which cells enhance the microbicidal abilities of phagocytes in the immune response?
Helper T cells
What is the distinction between B cells and T cells in recognizing antigens?
B cells recognize extracellular antigens, while T cells recognize intracellular antigens.
What happens during the processing step of the immune response?
Macrophages process antigens into small peptides for association with MHC proteins.
Which protein on T-cells binds to ICAM1 protein on APCs?
LFA-1
What is the function of the B7 protein on APCs in the immune response?
Interacts with CD28 protein on helper T cell
Which interleukin is crucial for efficient helper T cell activation?
Interleukin-1
What does IL-2 stimulate the helper T-cell to do?
Multiply into a clone of antigen-specific helper T cells
Which type of immunity is stimulated by exposure to infectious agents and improves upon repeated exposure?
Adaptive immunity
What are the two arms of adaptive immune responses?
Humoral and cellular
Test your knowledge on the cellular components of the adaptive immune response as discussed in Abbas's work from 2007. Questions cover topics such as lymphocytes, B cells, phagocytes, and T cells in relation to the immune system.
