Health control measures alone could be ineffective in the long term fight against the deadly Rift Valley fever which affects both humans and animals, a new study in the journal PNAS reports.
Nitric oxide gas produced by a type of harmful bacteria lets roundworms know to stay away from it, says a new study published in eLife.
A study shows that the expression of PI3Kγ protein increases during infection by T. cruzi, an essential response in avoiding excessive inflammation and controlling parasitemia. Heart tissue analyses involving human patients who developed cardiopathy in the disease's chronic stage also provided results. The next challenge is to devise treatment for Chagas using molecules capable of modulating the cellular signaling pathway mediated by PI3Kγ.
A Yale-led team of researchers have created a vaccine that protects against malaria infection in mouse models, paving the way for the development of a human vaccine that works by targeting the specific protein that parasites use to evade the immune system. The study was published by Nature Communications.
A nationwide investigation of the prevalence and distribution of ticks and exposure to tick-borne diseases highlights the value of public participation in science. The study, published on July 12 in the open-access journal PLOS ONE, was conducted by Nathan Nieto of Northern Arizona University and colleagues, and funded by Bay Area Lyme Foundation.
Researchers at the Morgridge Institute for Research shed light on the complex life cycle of Schistosoma, a parasite responsible for sickening hundreds of millions of people in the developing world.
A new study conducted at the University of Michigan reveals a previously unrecognized threat to monarch butterflies: Mounting levels of atmospheric carbon dioxide reduce the medicinal properties of milkweed plants that protect the iconic insects from disease.
Certain type of antibodies against α-Gal- a carbohydrate expressed by many organisms including the malaria parasite- could protect against malaria, according to a new study led by ISGlobal, an institution supported by 'la Caixa' Foundation. The results, published in Scientific Reports, indicate that a-Gal is an interesting candidate to include in future vaccines against malaria and other infectious diseases.
It has long been known that the pathogens causing sleeping sickness evade the immune system by exchanging their surface proteins. But now scientists at the German Cancer Research Center have found an additional parasite strategy to escape the immune system: they confuse the defense system with sugar. The sugar chains on the coat protein prevent the binding of protective antibodies and thus increase the pathogenic properties of the unicellular pathogens.
New research presents a technique that could help treat African sleeping sickness, which impacts millions in sub-Saharan Africa and -- in its late stages -- can be fatal.
