- 24. Type 2 interferon is Interferon alpha Interferon beta Interferon gamma Only interferon alpha and beta5. Explain a function for each of the types of T cells (Tн, Тс, ТR).6. In some viral infections, interferons, which are hydrophilic, are secreted by some white blood cells. These bind nearby cells causing uninfected cells to produce protective antiviral proteins. Based on this information, what type of signaling molecule are interferons? autocrine hormonal paracrine neural neurohormone
- 10. What are the functional differences between B cells and T cells?2. What cells in the innate immunity are responsible for causing phagocytosis?2. If a series of genetic mutations prevented some, but not all, of the complement proteins from binding antibodies or pathogens, would the entire complement system be compromised? Explain
- 10. What specific kinds of host cells do helper T cells respond to?5. A patient receives a donor kidney to replace diseased kidney tissue. Consider and answer the following: B) list two similarities and two differences between response mechanisms of natural killer cells and cytotoxic T cells to the tissue graft in the absence of immune suppression.8.The INNATE defenses can tell the difference between SELF and NONSELF to a certain extent. EXPLAIN how it does this. (HINT – Don’t mention MHC)
- 1. Describe the importance of T-cells for good health. Key terms: MHC, activation, apoptosis, autoimmune disorders44. Passive immunity differs from active immunity in that passive immunity results in the production of antibodies. involves the administration of preformed antibodies (produced outside the body) causes long-term immunity. results in the production of memory cells. is not effective against a preexisting condition.11.In the humoral response, some B cells differentiate into plasma cells. What do plasma cells produce in large quantities?
