Fig. 5From: IL-2 sensitivity and exogenous IL-2 concentration gradient tune the productive contact duration of CD8+ T cell-APC: a multiscale modeling studyThe productive CD8+ T cell-APC contact time varies with a the IL-2•IL-2R threshold level of individual T cells (without IL-2 supplement; mean ± SD; n = 10 simulations) and b the exogenous IL-2 concentration (with IL-2•IL-2R threshold = 51 molars; mean ± SD; n = 10 simulations)Back to article page
