Did you know?
Toxic shock syndrome toxin-1 (TSST-1) is a superantigen with a size of 22 kDa produced by 5 to 25% of Staphylococcus aureus isolates. It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumour necrosis factor. In general, the toxin is … See more Toxic shock syndrome toxin-1 (TSST-1), a prototype superantigen secreted by a Staphylococcus aureus bacterium strain in susceptible hosts, acts on the vascular system by causing inflammation, fever, and shock. The … See more TSST-1 is a protein encoded by the tst gene, which is part of the mobile genetic element staphylococcal pathogenicity island 1. The toxin is produced in the greatest volumes … See more A superantigen such as TSST-1 stimulates human T cells that express VB 2, which may represent 5-30% of all host T cells. PTSAgs induce the VB-specific expansion of both CD4 and CD8- subsets of T-lymphocytes. TSST-1 forms homodimers in most of its known … See more In the nucleotide sequence of TSST-1, there is a 708 base-pair open-reading frame and a Shine-Dalgarno sequence which is seven base pairs downstream from the start site. In the entire nucleotide sequence, only 40 amino acids make up the signal peptide. A … See more Samples of TSST-1 can be purified from bacterial cultures to use in in vitro testing environments, however this is not ideal due to the large number of factors that contribute to pathenogenesis in an in vivo environment. Additionally, culturing bacteria in vitro … See more WebThis risk is thought to be associated with colonisation by toxic shock syndrome toxin-1 (TSST-1)-producing Staphylococcus aureus in children with insufficient antibody titers. …
