UCHL5 and Salmonella Infections: Overexpression of UCH-L5 (but not overexpression of UCH-L3) for two days prior to the infection with Salmonella for one hour also lead to significant cell death (Fig 3B), while cell treatment with b-AP15 inhibitor prior to Salmonella infection led to slight increase in cell viability in comparison to vehicle-treated cells (S2 Fig).
