Question

Quizplus · Accepted Answer

Capsules are known to be potent T-independent antigens that can directly stimulate B cells without the help of T cells. Capsules are large polysaccharide molecules that can cross-link B cell receptors and activate B cell signaling pathways, leading to B cell proliferation and differentiation into antibody-secreting cells. Flagella, pili, ribosomes, and plasmids are usually not immunogenic enough to stimulate strong B cell responses without the help of T cells or other co-stimulatory signals.
