TH2 cells coordinate type 2 responses to expel intestinal helminths and repair tissue injury. The immune response to helminthic worm infections in the gastrointestinal tract requires specialized mechanisms due to the fact that helminths are too large to be ingested and destroyed by phagocytes. For example, cytokines made by TH2 cells elicit responses from multiple non-hematopoietic cell types that aid in parasite expulsion. Name two of these cell types and for each of them, their response to TH2-produced cytokines.

Although the complement cascade can be initiated by antibodies bound to the surface of a pathogen, complement activation is generally considered to be an innate immune response. This is because: Two of the three pathways for complement activation are initiated by constitutively produced recognition molecules that directly interact with microbial surfaces. When the complement cascade leads to the formation of a membrane-attack complex, the pathogen is killed. Several of the soluble products generated by complement activation lead promote the inflammatory response. Complement proteins bound to the pathogen promote uptake and destruction by phagocytic cells. The C3 convertase is only produced when complement activation is initiated by antibody binding to a pathogen.
Poliovirus is highly cytopathic both in cultured cells and in animals. Inoculation of mice with poliovirus leads to a robust antibody and cellular response. Explain why mice infected with a poliovirus mutant that cannot cause cell death have poor antibody and cellular responses. What would be one strategy to restore robust antibody and cellular responses in mice infected with this mutant virus?
In the antibody-mediated immune response, the binding of some antigen-presenting B cells to helper T cells initiates a signal transduction pathway that transforms the B cells into plasma cells, which will synthesize and secrete large quantities of antibodies-a specialized subset of proteins responsible for attaching to the antigen on the outer surface of pathogens. Which of the following describes the most relevant intracellular change to B cells as they are transformed into plasma cells? A B a breakdown of some membrane-bound proteins to allow synthesized antibodies to more readily diffuse across the membrane of the plasma cell с an increase in the surface area of the rough endoplasmic reticulum in order to allow the binding of a large number of ribosomes for antibody synthesis D an increase in the number of lysosomes in order to facilitate the storage of synthesized antibodies ahead of their transport out of the cell an increase in the volume of the mitochondria in order to increase…
Herpes Simplex Virus 1 (HSV-1) causes lifelong infection with potential for multiple reactivation events. Which of the following explain why the virus can cause repeat episodes of disease with reactivation in the presence of a secondary immune response? O HSV-1 requires a state of immunosuppression of HSV 1 specific memory cells to allow for reactivation O HSV-1 lacks PAMPS to be recognized by lymphocytes HSV-1 produces protein A that will inhibit IgA activity in the saliva HSV-1 interferes with IL-2 secretion HSV-1 disables MHC I and interferon alpha to suppress immune recognition
Which statement about antibodies is INCORRECT? Question 16 options: Antibodies can be both soluble and membrane-bound. Antibodies bind to antigens via induced fit. Antibodies never release antigens once they are bound together. More than 100 million different antibodies can be produced in humans. Antibodies typically bind to antigens more strongly than enzymes bind to substrates.
Adaptive Response Fill in the blanks.. Our specific defense system recognizes and fights autoimmune foreign molecules, or It can protect us antigens against like bacteria or viruses, or abnormal human cells like An allergy is the system's "overreaction" to things like pollen, cancer peanuts, or shellfish. The system can also target healthy pathogens human tissues causing diseases such as rheumatoid arthritis and multiple sclerosis. 11 O Teamwork Toolbox
Please answer the one question below, thanks. In 2013, there was an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) at an NFL training facility. One player suffered a career-ending infection to his foot and sued the team owners for $20 million for unsanitary conditions that contributed to the bacterial infection. A settlement with undisclosed terms was reached in 2017. MRSA is highly contagious and is spread by direct skin contact or by airborne transmission and can result in amputation or death. In addition, MRSA is very difficult to treat because it is resistant to many antibiotics. For example, β-lactamβ-lactam antibiotics, such as penicillin, function by binding to and inactivating bacterial penicillin-binding proteins (PBPs), which synthesize the bacterial cell wall. However, MRSA expresses an alternative type of PBP, called PBP2a encoded by the mecA gene. β-lactamβ-lactam antibiotics only weakly bind PBP2a, and thus cell wall synthesis can continue in their…
[q4 discussion #2] In a study investigating the effects of new anti-itch cream, participants with minor skin rashes were randomly divided into one of three groups. In the first group, participants received a new anti-itch cream that contained 3% hydrocortisone. In the second group, the participants received the standard cream available over-the-counter which contains 1% hydrocortisone. The third and final group members received a cream that contained 0% hydrocortisone. The participants did not know to which group they were assigned. Participants used the cream for three days to relieve itching symptoms caused by rash. After three days, each participant’s rash was examined to determine if itching symptoms subsided. If this was not the case, the participant was provided with the standard treatment, which is known to relieve itching. Is this a single or double blind study?
Which of the following would you anticipate would be secreted through the Type III secretion system during infection? a secondary messenger effector that is unable to cross the host cell membrane, such as the AexT protein that disrupts the host cell cytoskeleton the superantigen TSST that is responsible for the signs and symptoms associated with toxic shock syndrome a pore-forming cytolytic toxin, such as a hemolysin not enough information to determine the AB toxin responsible for the flaccid paralysis associated with botulism
Individuals or mice with defects in the biochemical pathways needed for loading peptides onto MHC molecules show greatly increased susceptibility to virus infections. Experiments examining the MHC molecules present on the surface of host cells in these individuals would show: Normal numbers of MHC molecules expressed on host cells, but no peptides bound to them. Very low levels of total MHC proteins expressed on the cell surface. Normal numbers of MHC proteins on the surface but all of them bound to self-peptides not pathogen peptides. Very high levels of total MHC proteins expressed on the cell surface. Only virus-infected cells expressing high levels of MHC proteins on the cell surface.
