What is usually required for B cell activation by an antigen?
A)other B cell interactions
B)T cell activity
C)platelets
D)megakaryocytes
E)erythrocytes

Question

Quizplus · Accepted Answer

B cell activation by an antigen usually requires T cell activity, specifically through the mechanism of T cell-dependent activation. This involves the binding of the antigen to a B cell receptor, processing and presentation of the antigen to a T cell, and subsequent activation of the B cell by T cell-derived cytokines. Other B cell interactions, platelets, megakaryocytes, and erythrocytes are not typically involved in this process.
