CXCL8 and infection: Infection of normal human lung fibroblast (IMR90) cells with measles virus (MV) triggers cellular senescence as revealed by the reduction of cell proliferation, the SA-beta-gal staining, the increase in the expression of p53 and p21 or the induction in the expression of SASP components such as interleukin-8 (IL-8) or the C–C motif chemokine ligand 5 (CCL5).
