Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is an important human pathogen that colonizes the gut mucosa via attaching and effacing (A/E) lesions; A/E lesion formation in vivo and ex vivo is dependent on the type III secretion system (T3SS) effector Tir. Infection of cultured cells by EHEC leads to induction of localized actin polymerization, which is dependent on Tir and a second T3SS ef...
Toll-like receptors (TLRs) recognise invading pathogens and initiate an innate immune response by recruiting intracellular adaptor proteins via heterotypic Toll/interleukin-1 receptor (TIR) domain interactions. Of the five TIR domain-containing adaptor proteins identified, Sterile α- and armadillo-motif-containing protein (SARM) is functionally unique; suppressing immune signalling instead of p...
Axonal degeneration is an early and prominent feature of many neurological disorders. SARM1 is the central executioner of the axonal degeneration pathway that culminates in depletion of axonal NAD+, yet the identity of the underlying NAD+-depleting enzyme(s) is unknown. Here, in a series of experiments using purified proteins from mammalian cells, bacteria, and a cell-free protein translation s...
AIM To obtain high-level expression of nonfusion recombinant human basic fibroblast growth factor (rhbFGF). METHODS hbFGF cDNA was prepared from the total RNA of embryonic brain tissue. As a template, the obtained gene was used to clone nonfusion rhbFGF. New primers were employed to alter the translation initiation region (TIR) and reduce the G+C content through nucleotide change. Using pET-3...
Ligand binding to Toll-like receptors (TLRs) results in dimerization of their cytosolic Toll/interleukin-1 receptor (TIR) domains and recruitment of post-receptor signal transducers into a complex signalosome. TLR activation leads to the production of transcription factors and pro-inflammatory molecules and the activation of phosphoinositide 3-kinases (PI3K) in a process that requires the multi...
Signaling through Toll-like receptors (TLRs), crucial molecules in the induction of host defense responses, requires adaptor proteins that contain a Toll/interleukin-1 receptor (TIR) domain. The pathogen Staphylococcus aureus produces several innate immune-evasion molecules that interfere with the host's innate immune response. A database search analysis suggested the presence of a gene encodin...
MyD88 adaptor-like (MAL) is a critical protein in innate immunity, involved in signaling by several Toll-like receptors (TLRs), key pattern recognition receptors (PRRs). Crystal structures of MAL revealed a nontypical Toll/interleukin-1 receptor (TIR)-domain fold stabilized by two disulfide bridges. We therefore undertook a structural and functional analysis of the role of reactive cysteine res...
Toll-like receptors (TLRs) belong to the Toll-like receptor (TLR)/interleukin-1 receptor (IL-1R) superfamily, which is defined by a common cytoplasmic Toll/interleukin-1 receptor (TIR) domain. These receptors recognize pathogen-associated molecular patterns and initiate an intracellular kinase cascade to cause an immediate defensive response. SIGIRR (single immunoglobulin interleukin-1 receptor...
We have been analysing the signalling systems that couple to receptors of the TIR (Toll/interleukin-1 receptor) family, which signal through a common cytoplasm region; the TIR domain. These systems are of both practical and fundamental biological significance, being central to the pathogenesis of chronic inflammatory diseases such as atherosclerosis, to host defence throughout the biological wo...
The DAN/TIR genes encode nine cell wall mannoproteins in Saccharomyces cerevisiae which are expressed during anaerobiosis (DAN1, DAN2, DAN3, DAN4, TIR1, TIR2, TIR3, TIR4, and TIP1). Most are expressed within an hour of an anaerobic shift, but DAN2 and DAN3 are expressed after about 3 h. At the same time, CWP1 and CWP2, the genes encoding the major mannoproteins, are down-regulated, suggesting t...
