Determine how the abundance of the interleukin-2 receptor beta subunit governs the temporal signaling dynamics and proliferative responses of CD4+ and CD8+ T cell subsets.
Stimulated CD4+ and CD8+ T cells with interleukin-2 under controlled conditions.
Measured intracellular signaling dynamics and proliferative response relative to surface receptor abundance.
Receptor abundance directly dictates the temporal pattern and duration of interleukin-2 signaling.
Differences in receptor density tune the magnitude of the proliferative response between CD4+ and CD8+ T cells.
