SRC and infection: Figure 1D, left, demonstrates how c-Src localized continuously throughout the formation of invaginations from the beginning until complete uptake of L. monocytogenes. The increased expression of c-Src at the L. monocytogenes invaginations during the infections did not correspond to changes in endogenous c-Src levels when compared to uninfected Jeg-3 cells (Figure 1D right).
