Human lung alveolar epithelial cells constitutively express class II major histocompatibility complex (MHC). Human lung microvascular endothelial and small airway epithelial cells can be induced to express class II MHC by stimulation with the pro-inflammatory cytokine interferon-gamma. The levels of class II MHC on lung epithelial and endothelial cells were(More)
Heparan sulphate N-deacetylase/N-sulphotransferase (NDST) enzymes catalyse the reaction that initiates sulphation and subsequent modification of the oligosaccharide, heparan sulphate (HS). The extent and distribution of sulphate substitution on HS plays a vital role in regulation of the binding of a range of proteins, including IFN-gamma, several(More)
The vascular and immune systems of mammals are closely intertwined: the individual components of the immune system must move between various body compartments to perform their function effectively. Sphingosine 1-phosphate (S1P), a bioactive lipid mediator, exerts effects on the two organ systems and influences the interaction between them. In the resting(More)
Hydatidosis was seen in 38.90% of cattle, 33.06% of buffaloes and 58.9% of camels slaughtered at a local abattoir. No statistically significant seasonal difference in prevalence was observed. Most cysts (63.14%) were infertile. Protein and carbohydrate contents of fluid from fertile and infertile cysts did not differ significantly. Sensitivity, specificity(More)
The transcription factor FOXP3 is widely known for its role in the development and function of immunoregulatory T cells. However, it has been discovered recently that FOXP3 is also expressed in epithelial cells of the normal human breast, ovary and prostate. Aggressive cancer of these epithelial tissues often correlates with abnormal expression of FOXP3,(More)
A functional sphingosine-1-phosphate (S1P) receptor antagonist specifically inhibited the egress of activated allospecific T cells from draining popliteal lymph nodes in alloantigen-sensitised mice. The level of S1P receptor 1 (S1PR1) mRNA was similarly reduced 1 and 3 days after mitogenic activation of T cells. However, the response of these cells to the(More)
OBJECTIVE To assess the safety of high dose non-ionic contrast media during a single radiological procedure in patients with pre-existing renal impairment. METHODS One hundred eighteen patients, with serum Creatinine greater than 1.3 mg/dl who were undergoing coronary angiography or percutaneous transluminal coronary angiography (PTCA) were included in(More)
PURPOSE The pattern of breast cancer metastasis may be determined by interactions between CXCR4 on breast cancer cells and CXCL12 within normal tissues. Glycosaminoglycans bind chemokines for presentation to responsive cells. This study was designed to test the hypothesis that soluble heparinoid glycosaminoglycan molecules can disrupt the normal response to(More)
The rate of spread of bovine brucellosis was investigated in buffalo and Jersey cattle herds maintained at a Livestock Research station in Pakistan. Reactor animals (identified by conventional serological tests) were either retained or culled because of advanced age or poor productivity. Reactors were housed, managed and fed separately from the rest of the(More)
The X-linked transcription factor FOXP3 is expressed by epithelial cells of organs including the breast, where it is considered a tumour suppressor. The chemokine receptor CXCR4 also regulates the development of breast cancer by stimulating cell migration towards CXCL12-expressing sites of metastatic spread. During activation, human T cells show reciprocal(More)
