OBJECTIVE To investigate the levels of the pro-inflammatory cytokines IL-6, TNF-alpha, IL-1beta, IL-8, IL-10 and IL-12p70 in the plasma of patients with TNF receptor-associated periodic syndrome (TRAPS) in relation to CRP levels and treatment with etanercept. METHODS Cytokine concentrations were measured in sequential plasma samples obtained from eight(More)
BACKGROUND/AIMS There is substantial evidence that mammalian epithelial stem cells are located within well defined niches. Although the corneoscleral limbus is acknowledged as the site of corneal epithelial stem cells no anatomical niche for such cells has yet been described. The authors undertook to re-evaluate the microanatomy of the limbus in order to(More)
Interleukin-12 (IL-12, p70) a heterodimeric cytokine of p40 and p35 subunits, important for Th1-type immune responses, has been attributed a prominent role in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Recently, the related heterodimeric cytokine, IL-23, composed of the same p40 subunit as IL-12 and a(More)
PURPOSE Defensins are naturally occurring antimicrobial peptides. Recently the authors published evidence of defensin production by the human ocular surface. A study was undertaken to look for intraocular defensins that may account for unexplained antimicrobial activity of intraocular fluids. METHODS Reverse transcription-polymerase chain reaction(More)
Cervical carcinogenesis is a multistep process initiated by 'high-risk' human papillomaviruses (HR-HPVs), most commonly HPV 16. Transforming growth factor-beta (TGF-beta) inhibits epithelial proliferation and down-regulates transcription of E6/E7 genes of HPV. Altered TGF-beta expression may be important in carcinogenesis. Quantitative RT-PCR was used to(More)
Multiplex immunoassays confer several advantages over widely adopted singleplex immunoassays including increased efficiency at a reduced expense, greater output per sample volume ratios and higher throughput predicating more resolute, detailed diagnostics and facilitating personalised medicine. Nonetheless, to date, relatively few protein multiplex(More)
AIMS To determine whether the infiltrating cells in the vitreous and subretinal fluid of patients with proliferative vitreoretinopathy (PVR) express messenger RNA for various cytokines found in this condition. METHODS The presence of mRNA coding for HPRT, IL-6, IL-1beta, IL-8, and TNFalpha was investigated in 20 vitreous and subretinal fluid (SRF) samples(More)
OBJECTIVE To investigate the effect of mutations in the tumor necrosis factor receptor superfamily 1A (TNFRSF1A) gene on the conformation and behavior of the TNFRSF1A protein. Mutations in TNFRSF1A cause the autosomal-dominant, autoinflammatory TNFR-associated periodic syndrome (TRAPS). METHODS The expression of recombinant TNFRSF1A was compared in(More)
BACKGROUND/AIMS The antimicrobial activity of the tear film exceeds the activity of its known constituents. The authors postulate that this excess activity is the result of antimicrobial peptides called defensins, and they aimed to look for defensins in the human eye. METHODS Evidence of defensin production was sought by reverse transcriptase polymerase(More)
OBJECTIVE To investigate the effect of mutations in tumor necrosis factor receptor superfamily member 1A (TNFRSF1A) in TNFR-associated periodic syndrome (TRAPS) on the binding of anti-TNFRSF1A monoclonal antibodies (mAb), and to investigate the subcellular distribution of mutant versus wild-type (WT) TNFRSF1A in patients with TRAPS. METHODS HEK 293 cells(More)
