La dermatophilose des bovins à Dermatophilus congolensis dans les Antilles françaises. II. Facteurs de réceptivité liés aux animaux

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1988
Une enquête portant sur 573 bovins élevés en milieu infecté a été menée dans les Antilles françaises afin de repérer les facteurs individuels favorisant l’apparition et l’évolution de la maladie.

Sensibilité des moutons soudaniens au virus de la fièvre catarrhale isolé sur des bovins apparemment sains au Soudan

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1990
L'étude tente de clarifier le rôle des bovins apparemment sains comme réservoir du virus de la fièvre catarrhale à l'égard des moutons au Soudan. Elle confirme les travaux antérieurs et établit que les bovins peuvent héberger le virus auquel sont ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Inhibition de l’infectiosité de Cowdria ruminantium dans des cellules endothéliales par les interférons alpha et gamma

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1993
Une corrélation positive entre la résistance de bovins à l'infection par Cowdria et la production précoce d'IFN a été démontrée auparavant. Les études in vitro rapportées ici ont montré une activité de rBoIFNalpha2C et de rBoIFNgamma contre Cowdria dans

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.
