True or False: The most abundant type of antibody, IgG, is the first to respond to an invading pathogen?
Step by step
Solved in 4 steps
- True/False: Antibody binding to a pathogen surface is greatly enhanced when both antigen-binding sites of the antibody are engaged at once, a feature known as bivalent binding. It is possible for antibodies to bind bivalently to a wide variety of components on many different pathogen surfaces due to the flexibility in the protein at the hinge region and at the V–C junction.True/False: Like innate sensors of infections (TLRs, NLRs, RLRs), antibodies frequently recognize nucleic acids of pathogenic organismsTrue or False: When a B cell’s antibody interacts with an epitope on the surface of the bacterium, the B cell secretes a toxin that kills the bacterium?
- Whether the statement, "Because a monoclonal antibody recognizes a specific antigenic site (epitope), it binds only to the specific protein against which it was made." is true or false.true or false the innate immunity system requires activation and must be specific to the invading pathogen.True/False: The different classes of immunoglobulins differ in the sequences of their heavy chain constant regions. As a result, each class of antibody has distinct effector functions. Nonetheless, they are all found at about equal concentrations in the serum of healthy individuals.
- True or False: Plasma B cells secrete antibodies into the bloodstream?True or false: the antigen binding site of an antibody is found in the variable region of the antibody.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 0
- How many types of “foreign molecules” (use the proper term where needed) does each cell recognize? On the pathogen side – what molecules will be recognized by these immune cells? (no need for specific names, just a few examples of pathogen molecules that will trigger an immune response) Bloodwork indicates that a patient who has pneumonia is actively secreting different forms of antibody against Streptococcus pneumoniae. Explain how the patient can respond to this pathogen by secreting more than one antibody.Antigens include proteins, polysaccharides, and various small molecules that stimulate antibody production. True or False?True or false: the antigen binding site of an antibody is found in the variabe region of the antibody.
