Question
1.1 Multiple Choice: Which of the following examples can be considered an illustration of vaccination? A. Inoculating an individual with cowpox in order to protect that individual against smallpox B. Administering the serum of animals immune to diphtheria to protect against the effect of diphtheria toxin in an exposed individual C. A bacterial infection that results in complement activation and destruction of the pathogen D. An individual that becomes ill with chickenpox, but does not develop it again due to the development of immunologic memory 1.2 Multiple Choice: Which of the following is an appropriate definition for immunological memory? A. The mechanism by which an organism prevents the development of an immune response against the host 's own tissues B. The mechanism by which an organism prevents exposure to microbes C. The persistence of pathogen-specific antibodies and lymphocytes after the original infection has been eliminated so that reinfection can be prevented D. The process of reducing or eliminating a pathogen 1.3 True or False: Toll-like receptors (TLRs) recognize ntracellular bacteria, while NOD-like receptors (NLRs) recognize extracellular bacteria.Explanation / Answer
1.1d. Chickenpox vaccine gives lifelong immunity and a person usually does not develops it twice.
an individual that becomes ill with chicken pox, but does not develop it gain due to the development of immunological memory.
1.2 c. Immunological memory is the ability of the immune system to quickly and specifically recognize an antigen that the body has previously encountered and initiate a corresponding immune response. This immune response will be faster so that the reinfection would generally not occur.
Persistence of pathogen-specific antibodies and lymphocytes after the original infection has been eliminated so that reinfection can be prevented- immunological memory.
1.3 true
tOLL like receptors are single, membrane-spanning, non-catalytic receptors usually expressed on macrophages and dendritic cells, that recognize structurally conserved molecules derived from microbes.
NOD-like Receptors (NLRs) are a subset of pattern recognition receptors (PRRs) found in the cytosol that are essential for detecting invading pathogens and initiating the innate immune response.
