Question

Quizplus · Accepted Answer

IL-4 is a cytokine that promotes the differentiation of naïve T cells into Th2 cells. Th2 cells are involved in initiating and regulating humoral immune responses, particularly those involving extracellular pathogens such as bacteria and parasites. IL-4 also promotes the differentiation of B cells into antibody-secreting plasma cells, which is important for the clearance of extracellular pathogens. It does not downregulate the immune response, increase production of neutrophils, or protect cells from viral invasion.
