Plasmodium development within Anopheles mosquitoes is a vulnerable step in the parasite transmission cycle, and targeting this step represents a promising strategy for malaria control. The thioester-containing complement-like protein TEP1 and two leucine-rich repeat (LRR) proteins, LRIM1 and APL1, have been identified as major mosquito factors that regulate(More)
The leucine-rich repeat (LRR) proteins LRIM1 and APL1C control the function of the complement-like protein TEP1 in Anopheles mosquitoes. The molecular structure of LRIM1 and APL1C and the basis of their interaction with TEP1 represent a new type of innate immune complex. The LRIM1/APL1C complex specifically binds and solubilizes a cleaved form of TEP1(More)
Vector-borne diseases, transmitted by bloodsucking arthropods, pose worldwide socio-medical and economical problems. Some of the major human infectious diseases, such as malaria, Dengue fever, and yellow fever, are transmitted by mosquitoes. While the majority of pathogens enjoy extracellular life styles in insects, viruses and some endosymbionts are(More)
The Rel/NF-kappaB transcription factor Relish is a major regulator of the antimicrobial response in Drosophila. Upon immune challenge, Relish is cleaved to generate two fragments, the DNA-binding transcription factor REL-68 and the IkappaB-like REL-49. Using transgenic fly strains we show here that overexpression of REL-68 separately from REL-49 is(More)
Malaria is an infectious disease caused by Plasmodium and transmitted to humans by the Anopheles mosquitoes. The mosquito immune system predominantly targets Plasmodium at the ookinete stage, and efficiently eliminates the majority of invading parasites. Identification of the components of the mosquito complement system now provides new focus for studies on(More)
OBJECTIVE Attention-deficit/hyperactivity disorder (ADHD) is increasingly diagnosed in adults. In this study we address the question whether there are impairments in recognition memory. METHODS In the present study 13 adults diagnosed with ADHD according to DSM-IV and 13 healthy controls were examined with respect to event-related potentials (ERPs) in a(More)
