All of the following protein-protein interactions are involved in the activation of naive helper T cells by antigen-presenting cells (APCs) EXCEPT: A. Binding of peptide-MHC complexes on the APC to the TCR on the T cell B. Binding of CD4 on the T cell to nonpolymorphic regions of class II MHC molecules on the APC C. Binding of integrins on the T cell with adhesion ligands on the APC D. Binding of B7-2 on the APC with CD28 on the T cell E. Binding of CD40L on the T cell with CD40 on the APC

Step 1
These interactions include: - Binding of peptide-MHC complexes on the APC to the TCR on the T cell - Binding of CD4 on the T cell to nonpolymorphic regions of class II MHC molecules on the APC - Binding of integrins on the T cell with adhesion ligands on the APC - Show more…

T cell receptor interactions are characterized by all of the following EXCEPT: Residues on the T cell receptor bind the major histocompatibility complex Residues on the T cell receptor bind the peptide presented by the major histocompatibility complex Residues on the T cell receptor cytoplasmic tail are phosphorylated after binding its ligand CD4 on the T cell binds to nonpolymorphic regions of the MHC class II molecule on the antigen-presenting cell

Which of the following correctly describes how cAMP acts as a second messenger? cAMP is produced by adenylate cyclase in response to G-protein activation, it activates many enzymes through cAMP-dependent protein phosphatase, and it is eliminated through cAMP phosphodiesterase. cAMP is produced by cAMP phosphodiesterase in response to G-protein activation, it activates many enzymes through cAMP-dependent protein kinase, and it is eliminated through adenylate cyclase. cAMP is produced by adenylate cyclase in response to G-protein activation, it activates many enzymes through cAMP-dependent protein kinase, and it is eliminated through cAMP phosphodiesterase. cAMP is produced by adenylate cyclase in response to G-protein deactivation, it activates many enzymes through cAMP-dependent protein kinase, and it is eliminated through cAMP phosphodiesterase.

A major difference between the activation of $\mathrm{B}$ cells and that of cytotoxic T cells is that a. cytotoxic T cells must interact with antigens bound to plasma membranes. b. $\mathrm{B}$ cells interact only with free antigens. c. $\mathrm{B}$ cells are not regulated by helper $\mathrm{T}$ cells. d. cytotoxic T cells produce antibodies. e. only cytotoxic T cells express immunoglobulins on their membranes.
