An insight into immunogenic salivary proteins of Anopheles gambiae in African children Inra
Cornelie, S.; Remoue, F.; Doucoure, S.; NDiaye, T.; Sauvage, F.X.; Boulanger, D.; Simondon, F..
Background: During blood feeding, the mosquito injects saliva into the vertebrate host. This saliva contains bioactive components which may play a role in pathogen transmission and in host-vector relationships by inducing an immune response in the vertebrate host. The evaluation of human immune responses to arthropod bites might also represent a research direction for assessing individual exposure to the bite of a malaria vector.Methods: The present study examined the antibody ( Ab) IgG response during the season of exposure to Anopheles gambiae bites in young children living in a malaria endemic area. Immunoblots were performed with An. gambiae saliva to detect anti-saliva Ab bands and the evolution of immunogenic bands at the peak of, and following, the...

Anopheles gambiae PRS1 modulates plasmodium development at both midgut and salivary gland steps Inra
Chertemps, T.; Mitri, C.; Perrot, S.; Sautereau, J.; Jacques, J.-C.; Thiery, I.; Bourgouin, C.; Rosinski-Chupin, I..
Background: Invasion of the mosquito salivary glands by Plasmodium is a critical step for malaria transmission. From a SAGE analysis, we previously identified several genes whose expression in salivary glands was regulated coincident with sporozoite invasion of salivary glands. To get insights into the consequences of these salivary gland responses, here we have studied one of the genes, PRS1 (Plasmodium responsive salivary 1), whose expression was upregulated in infected glands, using immunolocalization and functional inactivation approaches. Methodology/Principal Findings: PRS1 belongs to a novel insect superfamily of genes encoding proteins with DM9 repeat motifs of uncharacterized function. We show that PRS1 is induced in response to Plasmodium, not...

Réaction à un composé salivaire et tolérance à la coupe de génotypes de Dactylis glomerata L issus de populations ayant une expérience contrastée du pâturage Inra
Fily, M.; Tosca, C.; Balent, G..
Une étude comparative est réalisée sur 8 génotypes de dactyle (Dactylis glomerata L) récoltés dans 2 parcelles des Pyrénées qui ne diffèrent que par l’intensité du pâturage qui s’y exerce depuis 30 ans. Nous montrons, à l’aide de mesures de biomasses effectuées sur des plantes cultivées en pots à partir d’une talle unique : - que certains génotypes tolèrent mieux que d’autres la coupe, simulant le pâturage; - que la thiamine, mimant la salive des bovins, n’a pas d’effet constant sur la repousse des plantes; - qu’il y a une cohérence entre la capacité de repousse des génotypes et l’expérience que les populations ont du pâturage depuis 30 ans. Des notations du stade phénologique (structure morphologique) lors de chaque coupe permettent d’expliquer le...

The source of the saliva honeybees use to moisten materials they chew with their mandibles National Institute of Agronomic Research
Simpson, J..
The experiments described lead to the conclusion that this saliva comes from the labial glands, and not from the mandibular glands, as has sometimes been supposed. The mandibular glands have no mechanical connection with chewing, and their outlets are not on the mandibles.
