The Clara cell 16 kD protein (CC16), the predominant product of the Clara cells lining the bronchiolar epithelium, is thought to protect the respiratory and urogenital tract from unwanted inflammatory reactions through its immunosuppressive action. In this report, we show evidence that CC16 establishes an anti-inflammatory activity by interfering with the(More)
Protein 1 (P1), a low mol mass urinary protein of unknown function, has been purified, sequenced and quantified in human biological fluids. The molecular size, subunit composition and partial amino acid sequence of P1 are similar to those of the 10 kDa Clara cell protein (CC10), a lung secretory protein. P1 is found in high concentrations in sputum,(More)
The in vitro biosynthesis of metallothionein (MT) has been investigated in RBC precursors from human cord blood in order to support the hypothesis for the nucleated precursor origin of MT in human red blood cells (RBC). Human RBC precursors are obtained by (i) separating glycophorin A(+) (gly A(+)) cells using a magnetic cell sorting (MACS) technique and by(More)
During an immunohistochemical study of the distribution of the Bcl-2 proto-oncogene product in frozen sections of normal human skin, a hitherto unrecognized strong reactivity with melanocytes was observed. This prompted us to study Bcl-2 expression in a variety of pigment lesions. In nevocellular nevi, immunoreactivity gradually diminished or even(More)
The metallothioneins (MT), a family of proteins with relatively low molecular weight (6-7 kDa), are characterised by the intrinsic presence of 20 cysteinyl groups in their structure, which confers unique metal binding properties to the molecule. Since MT are involved in biological roles, quantification of MT remains an important task. To date, a large(More)
In this report, data are presented on the regulation of MHC class II antigen expression by a mediator present in supernatants of human mixed leukocyte cultures (MLC-SN), and which is different from IFN-gamma. The capacity of supernatants to induce antigen expression did not correspond to titers of IFN-gamma. Removal of IFN-gamma using either dialysis(More)
Zinc plays an important role in the maintenance of the immune system. While the mechanisms of zinc ions interaction with immune cells are still poorly understood, a striking concurrent effect of zinc is the induction of the biosynthesis of metallothioneins (MT), a group of low molecular weight, cysteine-rich metal-binding proteins, believed to play a role(More)
A short-term experiment was designed to measure the transcript levels of downstream genes contributing to the biosynthesis of steviol glycosides. Stevia rebaudiana plants were subjected to long- and short-day conditions for different time intervals. Samples from both lower and upper leaves were collected. Using quantitative real-time polymerase chain(More)
