Project description:Transmission of malaria is dependent on the successful completion of the Plasmodium lifecycle in the Anopheles vector. Major obstacles are encountered in the midgut tissue, where most parasites are killed by the mosquito’s immune system. In the present study, DNA microarray analyses have been used to compare Anopheles gambiae responses to invasion of the midgut epithelium by the ookinete stage of the human pathogen Plasmodium falciparum and the rodent experimental model pathogen P. berghei. Invasion by P. berghei had a more profound impact on the mosquito transcriptome, including a variety of functional gene classes, while P. falciparum elicited a broader immune response at the gene transcript level. Ingestion of human malaria-infected blood lacking invasive ookinetes also induced a variety of immune genes, including several anti-Plasmodium factors.

Project description:Although the basic anatomical sub-divisions of the larval mosquito gut were established several decades ago, information regarding their exact physiological roles is rather scarce. Several studies have reported differences between larval gut compartments in various morphological and physiological aspects. Unfortunately, the fragmentary and incomplete nature of this information makes it hard to establish clear links to the specific and/or unique physiological roles of each gut region. In this study, we attempted to identify transcripts significantly enriched in each gut section of the 4th instar Anopheles gambiae larva. We took advantage of a commercially-available microarray platform containing ~14,000 different An. gambiae transcripts (Affymetrix GeneChip® Plasmodium/Anopheles array, Affymetrix Inc., Santa Clara, CA). Based on the information obtained, we discuss the putative physiological roles of each major compartment of the larval gut, and identify potential new targets for larval control strategies.

Experiment Overall Design: We attempted to identify transcripts significantly enriched in each gut section of the 4th instar Anopheles gambiae larva. Signal intensities of transcripts from each gut section were compared to those of a matching group of whole 4th instar larvae using t-tests. Transcripts showing an intensity value two-fold or higher (p < 0.05) in each gut section as compared to whole larvae were considered to be significantly enriched.

Project description:We custom-built a bioinformatics pipeline to search for 20E-modifying enzymes in the accessory glands of Anopheles gambiae males, searching for ecdysteroid kinases (EcK), ecdysone oxidases (EO), and ecdysteroid-phosphate phosphatases (EPP). To this end, we generated RNAseq datasets of different An. gambiae tissues dissected from virgin and mated females and males, and produced similar datasets for Anopheles albimanus, a South American species that does not synthetize and transfer ecdysteroids during mating. These analyses led to the identification of one candidate EPP and two potential EcKs (EcK1 and EcK2), which we demonstrated are involved in the activity of a male-specific oxidized ecdysteroid (3D20E). We further determined that 3D20E is specifically produced by the An. gambiae male accessory glands and is transferred to females during copulation, where it triggers a series of post-mating responses.

Project description:Whole genome transcription was quantified in adult female and male Anopheles gambiae atdifferent ages; 0 (0-24 h), 10, 20 and 30 days post-eclosion. The objective of the experiment was to identify genes with significant age-dependent transcription.

Project description:Anopheles gambiae mosquitoes transmit the human malaria parasite Plasmodium falciparum, which causes the majority of fatal malaria cases worldwide. The hematophagous life style defines the mosquito reproductive biology and is exploited by P. falciparum for its own sexual reproduction and transmission. The two main phases of the mosquito reproductive cycle, pre-vitellogenic (PV) and post-blood meal (PBM) shape its capacity to transmit malaria. Transition between these phases is tightly coordinated to ensure homeostasis between mosquito tissues and successful reproduction. One layer of control is provided by microRNAs, well-known regulators of blood meal digestion and egg development in mosquitoes. Here, we report a global overview of tissue-specific miRNA expression during the PV and PBM phases and identify miRNAs regulated during PV to PBM transition. The observed coordinated changes in the expression levels of a set of miRNAs in the energy-storing tissues suggest a role in the regulation of blood meal-induced metabolic changes.
