African trypanosomiasis is also known as sleeping sickness. There are two types of African trypanosomiasis, East and West, named for the region of Africa in which they were historically found. People can get the disease if they are bitten by an infected tsetse fly, which is only found in Africa. Treatment is available for African trypanosomiasis, but it is fatal if left untreated.
The life-threatening African trypanosomiasis, also called sleeping sickness, is caused by protozoa of the species Trypanosoma brucei. A team at the Biocentre of the Julius-Maximilians-Universität Würzburg in Bavaria, Germany, studies the pathogens and has now reported exciting news: The trypanosomes have a so far unknown enzyme which does not exist in humans and other vertebrates. This makes it a promising target for therapy.
In a small, randomized Phase I/II clinical trial (SAT1), researchers at University of California San Diego School of Medicine say a 100-year-old drug called suramin, originally developed to treat African sleeping sickness, was safely administered to children with autism spectrum disorder (ASD), who subsequently displayed measurable, but transient, improvement in core symptoms of autism.
Blood-sucking flies can act as 'flying syringes' to detect emerging infectious diseases in wild animals before they spread to humans, according to research published in the journal eLife.
African Americans have a heightened risk of developing chronic and end-stage kidney disease. This association has been attributed to two common genetic variants - named G1 and G2 -- in APOL1, a gene that codes for a human-specific protein.
A Children's National Health System research team has uncovered a novel process by which the gene APOL1 contributes to renal disease, according to a paper published November 18 in the Journal of the American Society of Nephrology.
Researchers have made the first-ever detailed, atomic-level images of a peroxiredoxin, which has revealed a peculiar characteristic of this protein and might form the foundation for a new approach to antibiotics.
Researchers from Umea University in Sweden have discovered that the single-celled parasite causing African sleeping sickness has a defence mechanism against potential pharmaceuticals under development against the disease. The deadly parasite has an enzyme that can cleave and hence disarm adenosine analogue pharmaceuticals. This according to a study recently published in the Journal of Biological Chemistry.
While scientists have known for years that African trypanosomes cause sleeping sickness, they've been left scratching their heads as to how these tiny single-celled organisms communicate. A University of Georgia study, published Jan. 14 in the journal Cell, helps solve this mystery.
The Sohn Conference Foundation today announced a $50,000 grant to support funding of a Phase 2 cutting-edge pediatric clinical trial from the Neuroblastoma and Medulloblastoma Translational Research Consortium (NMTRC) now extending to New York City.
After having built the world's largest drug development pipeline for the most neglected diseases, the Drugs for Neglected Diseases initiative (DNDi) has unveiled plans for a more flexible, dynamic portfolio approach, integrating various operating models to better respond to the needs of patients, notably in low- and middle-income countries. The plan also paves the way for new diseases to be taken up in DNDi's portfolio.
Researchers at the Johns Hopkins University School of Medicine, along with colleagues at Emory University and Cedars-Sinai, have published in the journal Gastroenterology the first major, in-depth analysis of genetic risk factors of inflammatory bowel disease in African-Americans.
Researchers at the University of California, San Diego School of Medicine have launched a clinical trial to investigate the safety and efficacy of an unprecedented drug therapy for autism.
Today the national science academies of the G7 countries handed three statements to their respective heads of government for discussion during the G7 summit at Schloss Elmau in early June 2015. The papers on antibiotic resistance, neglected and poverty-related diseases, and the future of the ocean were drawn up by the seven national academies under the aegis of the German National Academy of Sciences Leopoldina.
At the turn of the millennium, the cost to sequence a single human genome exceeded $50 million, and the process took a decade to complete. Microbes have genomes, too, and the first reference genome for a malaria parasite was completed in 2002 at a cost of roughly $15 million. But today researchers can sequence a genome in a single afternoon for just a few thousand dollars. Related technologies make it possible to capture information about all genes in the genome, in all tissues, from multiple individuals.
Bayer HealthCare and the Drugs for Neglected Diseases initiative (DNDi) have signed an agreement under which Bayer will provide the active ingredient emodepside to support DNDi in its effort to develop a new oral drug to treat river blindness (or onchocerciasis). The world's second leading infectious cause of blindness, river blindness is a neglected tropical disease caused by a filarial worm.
In early drug discovery, you need a starting point, says Northeastern University associate professor of chemistry and chemical biology Michael Pollastri.
In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers at the University of California, San Diego School of Medicine report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neurological disorder in animals that were the human biological age equivalent of 30 years old.
Protein M is a cell surface protein from Mycoplasma Genitalium that binds to all human antibodies.
Caught in the act! Researchers from the University of Bristol have observed mating for the first time in the microbes responsible for African sleeping sickness. This tropical disease is caused by trypanosomes, single-celled parasites that are found in the blood of those afflicted.
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
