The identification of DC-derived signals orchestrating activation of Th1 and Th17 immune responses has advanced our understanding on how these inflammatory responses develop. However, whether specific signals delivered by DCs also participate in the regulation of Th2 immune responses remains largely unknown. In this study, we show that administration of antigen-loaded, IL-6-deficient DCs to naive mice induced an exacerbated Th2 response, characterized by the differentiation of GATA-3-expressing T lymphocytes secreting high levels of IL-4, IL-5, and IL-13. Coinjection of wild type and IL-6-deficient bone marrow-derived dendritic cells (BMDCs) confirmed that IL-6 exerted a dominant, negative influence on Th2-cell development. This finding was confirmed in vitro, where exogenously added IL-6 was found to limit IL-4-induced Th2-cell differentiation. iNKT cells were required for optimal Th2-cell differentiation in vivo although their activation occurred independently of IL-6 secretion by the BMDCs. Collectively, these observations identify IL-6 secretion as a major, unsuspected, mechanism whereby DCs control the magnitude of Th2 immunity. [less ▲]

Herpesvirus aotus type 2 (HVA-2) was isolated from a culture of kidney cells from a healthy owl monkey (Aotus trivirgatus). Bovine herpesvirus type 4 (BHV-4) is frequently isolated from diseased and even healthy cattle and occasionally from sheep, wild ruminants and cats. The two viruses are related antigenically, as was revealed by an indirect fluorescent antibody test using polyclonal antisera from experimentally infected rabbits or monoclonal antibodies raised against six BHV-4 proteins, three of which were glycosylated. The genome structures of the two viruses consist of a unique central sequence flanked at both ends by G + C-rich tandem repeats. Restriction maps (produced using EcoRI, BamHI and HindIII) of these two viruses were nearly identical but the unique sequence of the HVA-2 genome possessed two additional BamHI sites. Four genomic regions of variable size were detected, two located in the unique part, one in the repetitive part and one in the left junction between the unique and the repeated part of the genome; these slight variations were similar to those observed between various BHV-4 isolates. These results suggest that HVA-2 and BHV-4 belong to the same virus species; HVA-2 could be either a BHV-4 contaminant of owl monkey kidney cell cultures or an isolate from an owl monkey accidentally infected with BHV-4.

Bovine leukemia virus (BLV) p24 gene was expressed in Saccharomyces cerevisiae under the control of the PHO5 (encoding repressible acid phosphatase, rAPase) promoter. Yeast cells were transformed by a yeast-E. coli shuttle vector carrying the PHO5 promoter, the p24 gene and the CYC1 transcription terminator. After low inorganic phosphate (Pi) induction of the PHO5 promoter, p24 accumulated in the producing cells up to a concentration representing 10% of total soluble proteins. The expression level of p24 gene was not increased by insertion of the positive regulatory gene PHO4 on the p24 expression vector. The p24 produced in this system and incubated in crude yeast extract showed a remarkably high resistance to proteolytic degradation, a feature that presumably correlates with the compact globular conformation of the protein combined to the stabilizing effect of the N-terminal residue.

Twenty colonic adenocarcinomas were studied by immunofluorescence with antisera against components of the basement membrane: type IV collagen, laminin and heparan sulfate-rich proteoglycan, as well as antisera against antigens of the connective tissue: type-III collagen, fibronectin and hyaluronectin. Marked alterations of the basement membranes were consistently observed on staining with each one of the first three antisera. In contrast, staining of the normal components of connective tissue was in most cases as intense as in normal colonic mucosa. Hyaluronectin, a marker of peritumoral stroma, was found to be present in 12 out 15 tumors studied. [less ▲]

Non-insulin-dependent (type 2) diabetes mellitus (NIDDM) affects middle-aged or elderly people who frequently have several other concomitant diseases, especially obesity, hypertension, dyslipidaemias, coronary insufficiency, heart failure and arthropathies. Thus, polymedication is the rule in this population, and the risk of drug interactions is important, particularly in elderly patients. The present review is restricted to the interactions of other drugs with antihyperglycaemic compounds, and will not consider the mirror image, i.e. the interactions of antihyperglycaemic agents with other drugs. Oral antihyperglycaemic agents include sulphonylureas, biguanides--essentially metformin since the withdrawn of phenformin and buformin--and alpha-glucosidase inhibitors, acarbose being the only representative on the market. These drugs can be used alone or in combination to obtain better metabolic control, sometimes with insulin. Drug interactions with antihyperglycaemic agents can be divided into pharmacokinetic and pharmacodynamic interactions. Most pharmacokinetic studies concern sulphonylureas, whose action may be enhanced by numerous other drugs, thus increasing the risk of hypoglycaemia. Such an effect may result essentially from protein binding displacement, inhibition of hepatic metabolism and reduction of renal clearance. Reduction of the hypoglycaemic activity of sulphonylureas due to pharmacokinetic interactions with other drugs appears to be much less frequent. Drug interactions leading to an increase in plasma metformin concentrations, mainly by reducing the renal excretion or the hepatic metabolism of the biguanide, should be avoided to limit the risk of hyperlactaemia. Owing to its mode of action, pharmacokinetic interferences with acarbose are limited to the gastrointestinal tract, but have not been extensively studied yet. Pharmacodynamic interactions are quite numerous and may result in a potentiation of the hypoglycaemic action or, conversely, in a deterioration of blood glucose control. Such interactions may be observed whatever the type of antidiabetic treatment. They result from the intrinsic properties of the coprescribed drug on insulin secretion and action, or on a key step of carbohydrate metabolism. Finally, a combination of 2 to 3 antihyperglycaemic agents is common for treating patients with NIDDM to benefit from the synergistic effect of compounds acting on different sites of carbohydrate metabolism. Possible pharmacokinetic interactions between alpha-glucosidase inhibitors and classical antidiabetic oral agents should be better studied in the diabetic population. [less ▲]

Introduction : Réduire le risque de mortalité et morbidité cardiovasculaire (CV) chez le patient diabétique de type 2 (DT2) est primordial, mais les effets protecteurs semblent différents selon le mode d’intervention pharmacologique étudié. Patients et méthodes : Les données de mortalité (totale et CV) et morbidité (infarctus du myocarde ou IDM, accidents vasculaires cérébraux ou AVC) rapportées (réduction du risque relatif) dans les essais ayant testé un traitement anti-hyperglycémiant sont comparées avec les résultats publiés dans deux méta-analyses concernant les hypolipidémiants et les anti-hypertenseurs consacrées au DT2. Résultats : Les antihypertenseurs réduisent les IDM (-12%) et la mortalité globale (-13%) de façon comparable, et diminuent davantage les AVC (-27%). Les hypolipidémiants diminuent davantage les IDM (- 22%) et les AVC (-21%) que la mortalité globale (-9%) (ou la mortalité CV : - 13%). Les données concernant les antihyperglycémiants diffèrent considérablement selon les médications testées. L’insuline et les sulfamides (UKPDS) réduisent plus les IDM (- 21%) que la mortalité totale (-8%), mais augmentent les AVC (+ 14%). La metformine (UKPDS) réduit, de façon comparable, les IDM (-39%), les AVC (-41%) et la mortalité totale (-36%). La pioglitazone (PROactive) diminue davantage les IDM (-17%) et les AVC (-19%) que la mortalité (-4%). Les gliptines (combinaison de SAVOR TIMI 53, EXAMINE, TECOS) ont montré des effets globalement neutres sur la mortalité totale (0%), les IDM (-2%) et les AVC (-1%). L’empagliflozine (EMPA-REG OUTCOME) se singularise par un effet favorable nettement plus marqué sur la mortalité totale (-32 %) et CV (- 38%) que sur les IDM (-13%) ou les AVC (+18%). Conclusion : Les discordances observées suggèrent l’implication de mécanismes protecteurs différents selon les interventions testées. EMPA-REG OUTCOME, le seul essai démontrant un effet plus marqué sur la mortalité que sur les événements CV, suggère un mécanisme propre de l’inhibiteur des SGLT2. [less ▲]

ETHNOPHARMACOLOGICAL RELEVANCE: Artemisia campestris L. (Asteraceae) has many traditional uses, among which treatment of diabetes and hypertension. AIM OF THE STUDY: This study was conducted in order to confirm the antihypertensive and hypotensive effects of A. campestris L. aqueous extract (AcAE) and to explore the underlying mechanism of action of its vasorelaxant effect, besides the acute toxicity. Also, the chemical composition of AcAE was investigated. MATERIAL AND METHODS: the chemical content of AcAE was determined by using HPLC and NMR techniques. The antihypertensive effect was assessed indirectly by tail-cuff method on L-NAME induced hypertensive rats, while the hypotensive action was monitored intravenously by invasive method on normotensive rats. The vasorelaxant effect and vascular mechanism of action were studied in the presence of antagonists and blockers on aorta isolated from normotensive rats. On the other side, the acute toxicity was studied by oral feeding of extract to the mice. RESULTS: The global phytochemical profile of AcAE reveals the presence of several polyphenols as main components. A. campestris L. infusion was characterized by mono- and di-cinnamoyl compounds, with 3,5-dicaffeoylquinic (isochlorogenic A) acid being the main compound, followed by 5-caffeoylquinic (chlorogenic) acid. Vicenin-2 (apigenin 6,8-di-C-glucoside) appeared to be the most abundant compound among flavonoids. The daily treatment with AcAE at 150mg/Kg/day prevented the installation of hypertension on L-NAME hypertensive rats, and reduced SBP from 172mmHg up to 144mmHg. At the dose 40mg/Kg, AcAE provoked reduction of systolic (SBP), diastolic (DBP) and mean arterial pressure (MAP), without affecting the heart rate. Also, AcAE (10-2-2mg/ml) relaxed the precontracted aorta by 95.8 +/- 1.3%. The denudation and preincubation of aorta with atropine, calmidazolium, L-NAME, hydroxycobalamin, ODQ, 8-RP-Br-PET-cGMP, thapsigargin and verapamil attenuated the vasorelaxant response, while the pre-treatment with 4-AP, TEA, glibenclamide and BaCl2 did not alter this effect. The oral administration of AcAE (0-6g/Kg) reveals no mortality or toxicity. CONCLUSIONS: our study proved that AcAE possess an important antihypertensive, hypotensive and vasorelaxant effect, which is mediated via calmodulin-NO-cGC-PKG pathway, and via inhibition of calcium influx through voltage-operated calcium channels and activation of intracellular calcium mobilization into sarcoplasmic reticulum. Therefore, our findings give first evidence about the traditional use of A. campestris L. as antihypertensive plant. [less ▲]
