BACKGROUND
Recruitment of inflammatory cells in the lungs may contribute to tissue injury as a result of mediators released from these cells. Interleukin 1 beta (IL-1 beta) is a potent inducer of neutrophil accumulation, a process that may require local protein biosynthesis. Macrophage inflammatory
OBJECTIVE
To examine the expression of the matrix metalloproteinase, MMP-1, and the cysteine proteases, cathepsin B (CB) and cathepsin L (CL), in the synovial membrane (SM) of patients with early inflammatory arthritis.
METHODS
Samples of SM were obtained by blind needle biopsy or needle arthroscopy
Leukotrienes are important mediators of the eosinophilic influx and mucus hypersecretion in the lungs in a murine model of asthma. We used in situ PCR in this model of human asthma to detect lung mRNA for 5-lipoxygenase (5-LO) and 5-LO-activating protein (FLAP), key proteins necessary for
Cystatins represent a widely distributed superfamily of cysteine proteinase inhibitory proteins. We investigated the expression of the cystatin C gene, belonging to the family 2 of cystatins, in the hearts of female rats. Using a highly sensitive reverse transcriptase-polymerase chain reaction
The predominant pathological features in the central nervous system (CNS) in multiple sclerosis (MS) are perivascular inflammation and demyelination. The cells in the inflammatory cuff consist mainly of T lymphocytes and macrophages. Cytokines produced by inflammatory cells within the CNS have the
OBJECTIVE
To evaluate and compare early corneal wound healing and inflammatory responses after small incision lenticule extraction (SMILE) versus femtosecond laser laser in situ keratomileusis (LASIK).
METHODS
Thirty-six eyes of 36 rabbits underwent SMILE, while another 36 eyes of 36 rabbits were
We wished to determine if the inflammatory cells surrounding the airway mucus-secreting glands in chronic bronchitis (CB) were associated with interleukin (IL)-4 and IL-5 mRNA expression and whether the CD8 T cell population expressed these cytokines. Digoxigenin-labeled IL-4 and IL-5 antisense RNA
OBJECTIVE
To understand whether endotoxin lipopolysaccharide (LPS) is able to induce the expression of macrophage inflammatory protein-1alpha (MIP-1alpha) mRNA and protein in human umbilical vein endothelial cells (HUVECs).
METHODS
The expression of MIP-1alpha mRNA was determined by dot blotting
A sensitive in situ hybridization procedure using both digoxigenin and 35S-labeled riboprobes is described that allows detection of single T cells expressing cytokine mRNA species in both single and double label formats. Modifications to existing procedures have been developed that allow in situ
In situ hybridization techniques using a cocktail of digoxigenin-labelled T-cell receptor (TcR) constant (C) region beta oligonucleotide probes were used to detect TcR beta mRNA in frozen and paraffin-embedded tissue sections. The specificity of the C beta cocktail was confirmed by Northern blot
The polymerase chain reaction (PCR) is a sensitive method for the analysis of cytokine mRNA expression. The amount of specific mRNA in tissues involved in an inflammatory immune response can be low and therefore requires highly sensitive detection of the PCR products. In our study we have compared
The role of coxsackie virus infection in the pathogenesis of idiopathic inflammatory muscle disease (IIMD) has been investigated by many workers with conflicting results. This study uses in situ hybridization, with digoxigenin-labelled oligonucleotide probes complementary to the coxsackie B virus
The expression of mRNA encoding tumour necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1), IL-6 and IL-8 was studied, by in situ hybridization with a non-radioactive digoxigenin-labelled probe, in formalin-fixed, paraffin wax-embedded colonic tissue from pigs naturally infected with Salmonella
Several cytokines are involved in the pathophysiology of sarcoidosis. Granulocyte-macrophage colony-stimulating factor (GM-CSF) may be one of these cytokines because its mRNA is expressed by inflammatory cells obtained from the sarcoid lung. We thus asked two questions. Is GM-CSF secreted by
The detection and distribution of interleukin-1 (IL-1), tumour necrosis factor-alpha (TNF-alpha) and IL-6 were studied, by in-situ hybridization with a non-radioactive digoxigenin-labelled probe, in formalin-fixed paraffin wax- embedded lung tissue from 10 pigs naturally infected with Actinobacillus
