Nasal Colonisation by Staphylococcus aureus Depends upon Clumping Factor B Binding to the Squamous Epithelial Cell Envelope Protein Loricrin.
(2012)Staphylococcus aureus asymptomatically colonises the anterior nares, but the host and bacterial factors that facilitate colonisation remain incompletely understood. The S. aureus surface protein ClfB has been shown to ... -
Network analysis of the transcriptional pattern of young and old cells of Escherichia coli during lag phase.
(BioMed Central, 2009)Background The aging process of bacteria in stationary phase is halted if cells are subcultured and enter lag phase and it is then followed by cellular division. Network science has been applied to analyse the transcriptional ... -
Network rewiring: physiological consequences of reciprocally exchanging the physical locations and growth-phase-dependent expression patterns of the Salmonella fis and dps genes
(2020)The Fis nucleoid-associated protein controls the expression of a large and diverse regulon of genes in Gram-negative bacteria. Fis production is normally maximal in bacteria during the early exponential phase of batch ... -
NLRP1 restricts butyrate producing commensals to exacerbate inflammatory bowel disease
(2018)Anti-microbial signaling pathways are normally triggered by innate immune receptors when detecting pathogenic microbes to provide protective immunity. Here we show that the inflammasome sensor Nlrp1 aggravates DSS-induced ... -
No effect of intraspecific relatedness on public goods cooperation in a complex community
(2018)Many organisms—notably microbes—are embedded within complex communities where cooperative behaviors in the form of excreted public goods can benefit other species. Under such circumstances, intraspecific interactions are ... -
A novel anti-viral role for STAT3 in IFN-α signalling responses.
(Springer, 2017-05)The cytokine, Interferon (IFN)-α, induces a wide spectrum of anti-viral mediators, via the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway. STAT1 and STAT2 are well characterised ... -
A Novel Method to Identify and Characterise Peptide Mimotopes of Heat Shock Protein 70-associated antigens
(2006)The heat shock protein, Hsp70, has been shown to play an important role in tumour immunity. Vaccination with Hsp70-peptide complexes (Hsp70-PCs), isolated from autologous tumour cells, can induce protective immune responses. ... -
A novel Staphylococcus aureus biofilm phenotype mediated by the fibronectin-binding proteins, FnBPA and FnBPB.
(2008)Device-associated infections involving biofilm remain a persistent clinical problem. We recently reported that four methicillin-resistant Staphylococcus aureus (MRSA)strains formed biofilm independently of the icaADBC-encoded ... -
The nucleoid-associated protein HU controls three regulons that coordinate virulence, response to stress and general physiology in Salmonella enterica serovar Typhimurium
(2011)The role of the HU nucleoid-associated proteins in gene regulation was examined in Salmonella enterica serovar Typhimurium. The dimeric HU protein consists of different combinations of its ? and ? subunits. Transcriptomic ... -
Overexpression, purification and assessment of cyclosporin binding of a family of cyclophilins and cyclophilin-like proteins of the human malarial parasite Plasmodium falciparum
(2011)Malaria represents a global health, economic and social burden of enormous magnitude. Chemotherapy is at the moment a largely effective weapon against the disease, but the appearance of drug-resistant parasites is reducing ... -
P53 CODON 72 POLYMORPHISM AND HUMAN PAPILLOMAVIRUS ASSOCIATED SKIN CANCER
(2001)BACKGROUND/AIMS-NON-MELANOMA SKIN CANCERS FREQUENTLY HARBOUR MULTIPLE HUMAN PAPILLOMAVIRUS (HPV) TYPES. A RECENT REPORT SUGGESTS THAT ALPOLYMORPHISM OF THE P53 TUMOUR SUPPRESSOR GENE THAT RESULTS IN THE SUBSTITUTION OF A ... -
Packing a punch: Understanding how flavours are produced in lager fermentations
(2021)Beer is one of the most popular beverages in the world and it has an irreplaceable place in culture. Although invented later than ale, lager beers dominate the current market. Many factors relating to the appearance (colour, ... -
Pathogenomic analysis of the common bovine Staphylococcus aureus clone (ET3): emergence of a virulent subtype with potential risk to public health
(University of Chicago Press, 2008)A common clone (ET3) of Staphylococcus aureus is responsible for a large proportion of cases of bovine mastitis and occasionally causes zoonotic infections of humans. In the present study, we report the identification of ... -

Pervasive post-transcriptional control of genes involved in amino acid metabolism by the Hfq-dependent GcvB small RNA.
(2011)GcvB is one of the most highly conserved Hfq-associated small RNAs in Gram-negative bacteria and was previously reported to repress several ABC transporters for amino acids. To determine the full extent of GcvB-mediated ... -
PEST sequences in the malaria parasite Plasmodium falciparum: a genomic study
(BioMed Central, 2003)Anopheles gambiae is the main vector of Plasmodium falciparum in Africa. The mosquito midgut constitutes a barrier that the parasite must cross if it is to develop and be transmitted. Despite the central role of the mosquito ...
