Chronic infection of woodchucks with woodchuck hepatitis virus (WHV) was associated with the development of hepatitis, foci of altered hepatocytes and hepatocellular adenomas and carcinomas. The cytomorphological and cytochemical analysis permitted the identification of three different types of
The total membrane-bound ATP hydrolytic activity in human epidermis is due to the activities of at least three differently located enzymes, namely Mg++-activated ATPase, phosphomonoesterase and adenyl cyclase. Cytochemical studies on psoriatic epidermis with various inhibitory and stimulatory
BACKGROUND
Dendritic cells (DCs) are professional antigen-presenting cells and have critical roles in regulating immune responses. Prostaglandin I2 (PGI2) analogs are considered to be potential treatments for asthma. However, the effect of PGI2 analogs on human monocyte-derived DCs (MDDCs) is still
OBJECTIVE
C-Reactive protein (CRP), a cardiovascular risk marker, could also participate in atherosclerosis. Atherosclerotic plaques express CRP and interleukin (IL)-10, a major antiinflammatory cytokine. IL-10 deficiency results in increased lesion formation, whereas IL-10 delivery attenuates
Regulation of GH gene expression by GRF involves cAMP as a second messenger. We have demonstrated that a 500-basepair fragment of the human GH (hGH) gene 5' flanking region can confer cAMP inducibility upon the chloramphenicol acetyltransferase transcription unit in transient transfections of rat
Interleukin-6 is a multifunctional cytokine that is found in high concentrations in intraocular fluids during the uveitic response. Although monocytic cells are a major source of interleukin-6, resident intraocular cells may also contribute to its accumulation in intraocular fluids during uveitis.
Fibroblasts of the pulmonary interstitium are intimately involved in the response of the lung to inflammation as well as in repair of injured tissues. The response of fibroblasts within an inflammatory site appears to be directed, in part, by peptide mediators. Neutral endopeptidase (NEP), a
The phenotypes of the human renal epithelial cell lines, SK-NEP-1 and G401 (Wilm's tumour lines) and ACHN, A498, A704, Caki-1 and Caki-2 (renal adenocarcinomas), were investigated in order to develop as toxicological model systems, human renal cell lines showing properties similar to those found in
BACKGROUND
A common finding amongst patients with inhalational anthrax is a paucity of polymorphonuclear leukocytes (PMNs) in infected tissues in the face of abundant circulating PMNs. A major virulence determinant of anthrax is edema toxin (ET), which is formed by the combination of two proteins
Plant proteins have a reduced content of essential amino acids in comparison to animal proteins. A significant reduction of limiting amino acids (methionine, lysine, tryptophan) means lower protein synthesis. In subjects with predominant or exclusive consumption of plant food a higher incidence of
Cartilage breakdown, as seen in inflammatory and degenerative joint diseases, can be mediated by proteolytic enzymes, such as the metalloproteinase collagenase, the only enzyme able to digest collagen at neutral pH. In vitro collagenase gene expression can be stimulated by the phorbol ester tumor
This study demonstrates a synergistic action of prostaglandin E and GM-CSF which causes the release of pro-tolerant cytokines in two monocyte cell lines: U937 and ML-1. The prostaglandin effect is cyclic AMP dependent since stimulators of adenyl cyclase such as forskolin (fsk) can replace PGE. Fsk
Adenine (6-amino-6H-purine), found in molokheiya (Corchorus olitorius L.), has exerted vasorelaxation effects in the thoracic aorta. However, the mode of action of the anti-inflammatory effect of adenine is unclear. Thus, we investigated to clarify the effect of adenine on chronic inflammation of
Malignant melanomas harbouring point mutations (Val600Glu) in the serine/threonine-protein kinase BRAF (BRAF(V600E)) depend on RAF-MEK-ERK signalling for tumour cell growth. RAF and MEK inhibitors show remarkable clinical efficacy in BRAF(V600E) melanoma; however, resistance to these agents remains
