5.DISEASE AND PATHWAYS: Most drugs target proteins involved in signaling pathways in the cell. Describe two examples by which a protein can be chemically altered and thereby act as a logic switch in a signaling pathway in the cell. 6.MOLECULAR DRUG DOCKING: Why is molecular docking (e.g. autodock vina) take less time to run than molecular dynamics? What aspect of molecular reality regarding the target protein is sacrificed during simulation to obtain computational speed?

1)You inject a mouse with a protein antigen X. This is the first time the mouse has been exposed to X. In the course of clearing X from their body the mouse will launch an immune response to antigen X. Over the course of the immune response antigen X will encounter naïve, effector and memory lymphocytes (B- and T-cells). There are distinct differences between the function and role of each type (naïve, effector and memory).Differentiate between naïve, effector and memory lymphocytes. Focus...

Which of the following statements is (are) true of a T cell that expresses two α chains (and thus two different T-cell receptors) as a result of ineffective allelic exclusion of the α chain during rearrangement? There will be two unique TCRs on the surface of this T cell. Engaging either of the T-cell receptors on MHC molecules of the thymic epithelium will result in positive selection. If either T-cell receptor binds strongly to self-peptide presented by self-MHC molecules, the...

1. The prevention of inflammatory immune responses to inhaled antigens in healthy individuals has mechanisms in common with those that prevent inflammatory immune responses to commensal microbes in the gut. One important component of immune regulation shared by these two situations is: a. The induction of increased numbers of IFN-g-producing T cells and ILCs in the airway and gastrointestinal epithelium b. The presence of tissue-resident mast cells that bind IgE through the high affinity IgE receptor c. The high levels...
