. What does the FcεRII (CD23) regulate?
the Increasing/Decreasing production of IgE by B cells
If a Mast cell is expressing both FcεRII (activating) and FcγRIIB (inhibiting) Ig receptors and it binds to a IgE and IgG, the activating signal is induced. (True/False)
False
When the both are binded the inhibiting signal is induced
T/F: hemolytic anemia can be drug induced.
True
