WebTreg cells have been shown to restrict T cell function through diverse methods including contact-dependent and cytokine-mediated mechanisms. These include the secretion of TGF-b which has been shown to be a potent regulator of effector T cell function, IL-10 which can function as a T cell inhibitory cytokine in a context-dependent manner, and IL-35 … WebCytokine profiling is commonly used to classify the Th cell subtype and also to quantify the amount of cytokines secreted. Cytokine ELISAs can be used to monitor T cell dependent cytokine secretion in response to activation and lineage-specific differentiation at the population level. WebKey cytokines secreted by Tfh cells include IL-21 and IL-4 which in combination with the co-stimulatory molecule CD40L provide the signals that are required for B cell proliferation and differentiation. IL-21 secretion precedes the expression of IL-4, which is only acquired upon full differentiation of Tfh cells in the germinal centers. dianthus shirley temple
