Cells in the blood that probably function in the same way as tissue mast cells are: a) neutrophils b) eosinophils c) macrophages d) basophils Which of the following types of cell suppress the immune system? A) Neutrophils B) Macrophages C) Regulatory cell D) Plasma...
It forms complexes with circulating IgE, thus inhibiting the binding of IgE to the high-affinity IgE receptor on the surface of mast cells and basophils. Omalizumab is administered subcutaneously every 2–4 weeks. It is well tolerated and can replace steroidal treatment for asthma. 1.03.7.1.7 ...
