Module 3 – B-activation and antibody production 15. Describe the interaction between the B-cell and the helper T-cell in Model 3. Make sure include all the receptors involved. 16. When a B-cell is activated by the interaction with an activated CD4 T-cell it begins to produce and release antibodies. According to Model 3, what does the antibody do to pathogens? 17. What do the following have in common? T-cell receptor from T-cell #2 in Module 1, B-cell receptor from B-cell #1 in Module 2, and the antibodies in Module 3?

The interaction between the B cell and the helper T-cell in Model involves the following receptors: - B cell receptor (BCR) on the B cell binds to the specific antigen. - CD40 receptor on the B cell interacts with CD40 ligand (CD40L) on the helper T-cell. - Major Show more…

Much like T cells, B cells require 3 signals to become activated. Which option describes an event that does NOT occur during B cell activation? Question options: 1) NaĂŻve B cell recognizes unprocessed antigen in its native form via B cell receptor (BCR). 2) CD4 T cell (Th cell) previously activated by the same antigen interacts with antigen-experienced B cells to complete the B cell activation. 3) Signal 2 during B cell activation is the interaction of CD28 on Th cells with CD80 or CD86 on DCs. 4) Cytokines produced by Th cell during its interaction with antigen-experienced B cell determine the antibody isotype to be produced as a result of class switch recombination.

QUESTION 59 Which of the following are true about the T cell Activation & Response? Activated T cells activate other cells involved in both specific & non-specific immunity T cell binds to processed antigen displayed on a MHC receptor Referred to as the humoral response/immunity Referred to as the cell-mediated immunity (CMI) Activated T cells produce Plasma cells Activated T cells seek out infected cells & destroy them with perforins & granzymes T cell displays processed antigen on MHC II receptor T cell binds to unprocessed antigen with T cell receptor & then processes it Produce antigens T cell is presented with an antigen by an APC Activated T cells secrete antibodies QUESTION 60 What type of cells secrete antibodies?
