Quizplus · Accepted Answer

T-cell receptors (TCR) interact with antigens as part of the T-cell's role in the immune response, leading to T-cell proliferation and differentiation. However, immunoglobulins (Ig) bind to antigens but do not directly cause B-cells to proliferate and differentiate; this process requires additional signals from helper T-cells. Immunoglobulins primarily function as antibodies, recognizing and binding to antigens to mark them for destruction or neutralization.
