Web23 nov. 1999 · LPS causes STAT1 Ser727 phosphorylation and thereby increases IFN-γ-induced, Stat1-dependent transcriptional responses. From the results shown above, one would expect SB203580 to inhibit the augmenting effect of LPS but to be without a significant effect on transcriptional induction by IFN-γ alone. Web15 nov. 2005 · To explore the relevant mechanisms, we first investigated whether JAK–STAT was directly involved in LPS signaling because JAK–STAT proteins are the target of SOCS-1. We found that LPS directly activated Jak2 and Stat5, whereas SOCS-1 inhibited LPS-induced Jak2 and Stat5 activation. the hepburn sisters https://fredstinson.com
