Assignment:
1-Dendritic cells (DCs) are the key link between innate immunity and adaptive immunity and play crucial roles in both the promotion of immune defense and the maintenance of immune tolerance.
Indicate whether this statement is true or false, and then, explain your answer in detail.
2-The receptors found on cytotoxic T cells, called killer-cell inhibitory receptors, bind to MHC Class 11 cells and activate Cytotoxic T cells.
Indicate whether this statement is true or false, and then, explain your answer in detail.
3-The acute phase response is stimulated by cytokines produced by adaptive immune cells.
Indicate whether this statement is true or false, and then, explain your answer in detail.
4-The edema associated with inflammation, is caused by vasoconstriction and decreased vascular permeability.
Indicate whether this statement is true or false, and then, explain your answer in detail.
5-Cytokines exhibit the attributes of pleiotropy. This is a way of saying that two or more cytokines that mediate similar functions by the common use of cytokine receptor signaling subunits.
Indicate whether this statement is true or false, and then, explain your answer in detail.
6- The differentiation of macrophages occurs from thymic precursors via signaling from cortical thymocytes and express TCRs like other T lymphocytes.
Indicate whether this statement is true or false, and then, explain your answer in detail.
7- Cytokines function to stimulate hematopoiesis, facilitate innate immune responses and affect leukocyte movement
Indicate whether this statement is true or false, and then, explain your answer in detail.
8- Natural killer cells are large granular lymphocytes that proliferate in response to antigen. Their killing is intracellular, and their target cells are bacterial cells. They are not particularly effective against virus-infected cells or tumor cells.
Indicate whether this statement is true or false, and then, explain your answer in detail.
