A vaccine is attempting to stimulate the adaptive immune system to create memory. (slide 1:2) a. true b. false - a. true A vaccine is attempting to stimulate the adaptive immune system to create a better innate response. (slide 1:2) a. true b. false - b. false *A vaccine is attempting to stimulate the adaptive immune system to create MEMORY. However, we are just beginning to appreciate the role of the innate immune system in this process. In order to produce memory killer T cells which ...

T-cell receptors, when coexpressed with CDS mole cules, are restricted to recognizing and binding peptide fragments associated with A. CD3 molecules. B. CD4 molecules. C. MHC class I molecules. D. MHC class II molecules. E. MHC class Ill molecules. - The correct answer is C. cos+ T cells are re stricted to the recognition of pMHC I complexes. C03 molecules are associated with the TCR on the T-cell surface and are found on both mature C04+ and cos+ T cells. C04+ T cells are restricted to ...

______ greatly activates the classical pathway of complement activation - IgM _______ is expressed by T cells whose function is to activate other cells. - CD4 ___________ is expressed by cytotoxic T cells - CD8 ____________ molecules present peptides from pathogens, commonly viruses, to CD8 T cells, which are specialized to kill any cell that they specifically recognize. - MHC class I _____________ increases the expression of both MHC Class I and MHC Class II molecules, and can induce the ...

Antigen Shape to Antibody Shape - Answer-Simple = Pocket Large = Groove Complex = Extended Surface Type of chemical bond used with antibodies - Answer-1)Electrostatic 2) Hydrogen bonds 3) Van der Waals forces 4) Hydrophobic interactions Cross reactivity - Answer-The biding site can accept a shape close enough in shape and get reaction or a stable structure Ex.

What is the hapten-carrier effect? correct answer: Small-molecule antigen requires covalent linkage to a larger carrier to stimulate adaptive immune response. The process is achieved in collaboration between hapten-specific B cells and carrier-specific T cells. This is the basis of developing conjugated vaccines. What are the common superantigens and related diseases? correct answer: SEB and SEC from Staphylococcus aureus cause food poisoning. TSST from Staphylococcus aureus and SPE-C from ...
