Preliminary assessment of the therapeutic potential of staphylococcal enterotoxin-like W via biological activity and TCR binding sites analysis.

ABSTRACT: Staphylococcal enterotoxin-like W (SElW) is a novel, widely prevalent enterotoxin-like protein that functions as a classical staphylococcal superantigen (SAg) and has been shown to exacerbate infections caused by the S. aureus epidemic clone CC398. However, the genetic distribution and amino acid polymorphisms, biological and antitumor activity, and T cell receptor (TCR) binding sites of SElW in S. aureus strains prevalent in China have not been investigated. The carrier rate and distribution of selw were determined by PCR, the stability and antitumor activity of recombinant SElW (rSElW) protein were evaluated. The superantigen activity of the five mutants (Y18A, N19A, W55A, C88A, and C98A) was compared to that of wild-type SElW (WT-rSElW) to assess the role of these s
