WebStrikingly, a similar effect is also observed with other toxins of the same family, such as Clostridium perfringens perfringolysin (PFO) and Streptococcus pneumoniae pneumolysin (PLY). The decreased levels of histone modifications correlate with a reduced transcriptional activity of a subset of host genes, including key immunity genes. WebContact-dependent pneumolysin (Ply) activity of wild type TIGR4 cells was ten-fold greater than that of ΔsecA2 mutant cells suggesting that Ply was not active at the ΔsecA2 cell surface. Ply protein was found to be present in the CWP fraction from the ΔsecA2 mutant, but showed aberrant electrophoretic migration indicative of protein modification. foster\u0027s hot tub repair
