The answer is True.
The immune response in allergy starts with sensitization. If any pollen allergens are inhaled, antigen presenting cells in epithelium of the airways of lungs and nose process these allergens to their cell surface. The allergen is then involved in immune response of T-lymphocytes. After a series of cell interactions, B lymphocytes are transferred into antibody secretory plasma cells. The plasma cells produce IgE antibodies. Once formed and released into circulation, IgE binds to high affinity FC receptors on mast cells or basophils. This immune response is termed sensitization.

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
