TYPES OF IMMUNE RESPONSE

Which cell is responsible for the  Cell-Mediated Immune Response?

• Memory B cell

• Plasma cell

• T cell

• B lymphocyte

Which of the following types of immune responses involves antigens binding directly to the B cells causing the production of antibodies?

• cell‐mediated immunity

• herd immunity

• humoral immunity

• APC immunity

What is the cytokine involve that serve as communicator between lymphocyte?

• lymphokines

• interleukin-1

• interleukin-II

• interleukin- 3

Which of the pathway that would lead to the activation of cytotoxic T cells?

• B cell contact antigen → helper T cell is activated → clonal selection occurs

• Complement is secreted → B cell contacts antigen → helper T cell activated → cytokines released

• Cell becomes infected with virus → new viral proteins appear →MHC-Ag complex display on surface

• Self-tolerance of immune cells → B cells contact antigen → cytokines released

Which of the following cells are involved in cell-mediated immunity and also respond to class I MHC molecule-antigen complexes?

• helper T cells

• natural killer cells

• cytotoxic T cells

• macrophages

Which of the following cell types mediates adaptive immune responses?

• Dendritic cell

• natural killer cells

• Lymphocyte

• macrophages

What is the function of antibodies?

• Inject toxins into living pathogens.

• Release perforin to disrupt infected cells.

• Mark pathogenic cells for destruction

• Secrete cytokines that attract macrophages to infection sites.

Which of the following statements is true about the humoral immune response?

• it is responsible for transplant tissue rejection

• it protects the body against cells that become cancerous

• it is mounted by lymphocytes that have matured in bone marrow

• it primarily defends against bacteria and viruses that have already infected cells

Which of the following types of cells is not involved in both humoral and cell mediated immune response?

• plasma cells

• helper T cells

• pathogenic cells

• memory cells

Which type of T cell lyses cells that have been infected with viruses?

• inducer T cells

• Suppresor T cells

• Cytotoxic T cell

• Helper T cells
