Concept explainers
To explain: The role of helper T-cells.
Introduction:: Antibody-mediated immunity and cell-mediated immunity are two types of immunities, which comprise of the immune system of an individual. Cell-mediated immunity involves the activity of T-cells. In general, there are two types of T-cells: T-helper cells and T-cytotoxic cells or killer-T cells.
To explain: The role of killer T-cells in the immune system.

- The Adaptive Immune Response Is a Specific Defense Against Infection Name the class of molecules that includes antibodies, and name the five groups that make up this class.arrow_forwardThe Adaptive Immune Response Is a Specific Defense Against Infection Identify the components of cellular immunity, and define their roles in the immune response.arrow_forwardThe Adaptive Immune Response Is a Specific Defense Against Infection Compare the general inflammatory response, the complement system, and the specific immune response.arrow_forward
- The ability to develop a secondary immune response is based on ______. a. memory cells b. circulating antibodies c. plasma cells d. effector cytotoxic T cells e. mast cellsarrow_forwardThe innate immune response together with antibodies are generally not effective at clearing infections established by pathogens that replicate inside host cells. The evolution of T cells has provided a means for the immune response to ‘see’ intracellular infections based on the ability of T cells to: Secrete cytokines that diffuse into the infected tissue Activate type I interferon production by macrophages and dendritic cells Activate macrophages to induce inflammation Recognize pathogen-derived peptides on host MHC surface molecules Express cytoplasmic sensors for detecting pathogen-derived nucleic acidsarrow_forwardDescribe how T cells are activated during the development of a specific immune response. e.i. After vaccinationarrow_forward
- Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. One example is the tetanus vaccine, in which neutralizing antibodies are generated against an inactivated form of the tetanus toxin (the tetanus toxoid). The most important feature of a neutralizing antibody is having high affinity for the antigen. being efficient at activating the complement cascade. having a high degree of multivalency, such as being a pentamer or hexamer of immunoglobulin monomers. being present at a high concentration in the circulation. 0 0 0 0arrow_forwardWith the aid of a hand drawn diagram, briefly explain how T cells are primed or activated by B cells. In your response, briefly outline the major differences between B and T cell activationarrow_forwardTrue/False: Dendritic cells are tissue resident myeloid cells that are highly phagocytic, like macrophages. However, dendritic cells do not play a major role in large-scale pathogen destruction; instead, they are important in initiating adaptive immune responses of T cells.arrow_forward
- Which of the following are true of interferons? Select all that apply. O They are a critical part of the innate immune system in fighting bacterial infections O They are a part of the second line of defense against viruses O They degrade viral DNA O They are signaling molecules produced by infected cells to help uninfected cells defend themselves agains viruses O They are part of innate immunity O They are part of adaptive immunity and are "trained" by the immune system to eliminate specific pathogensarrow_forwardWhich of the following is INCORRECT Select one: Degradability is T cell requirement of immunogenicity Simpler compound structure has higher immunogenicity All the listed choices are incorrect The more complex the structure the higher immunogenicityarrow_forwardWhich of the following is a component of the first line of defense in the innate defense system? T cell activation phagocyte and natural killer cell activation secretion of sweat and sebum onto the epidermis all the above a and barrow_forward
