New paper sheds light on harnessing the clinical potential of microvesicles released from cancer cells

Author: William G. Gilroy

Tumor cell surrounded by shed microvesicles

Over the past few years, extracellular vesicles, or membrane sacs secreted from cells, have emerged as important mediators by which cells communicate with their surroundings to regulate a diverse range of biological processes. In addition, specialized roles for extracellular vesicles are beginning to be recognized in various diseases including cancer, infectious diseases and neurodegenerative disorders. Moreover, engineered extracellular vesicles are likely to have applications in drug delivery.

Researchers identify molecular mechanism responsible for making malaria parasites drug-resistant

Red blood cells infected with the malaria parasite P. falciparum at the "ring" stage, either sensitive or resistant to artemisinins

University of Notre Dame researchers led an international team to identify a molecular mechanism responsible for making malaria parasites resistant to artemisinins, the leading class of antimalarial drugs.

According to the World Health Organization’s 2014 World Malaria Report, there are an estimated 198 million cases of malaria worldwide with 3.3 billion people at risk for contracting the infection. Although the impact of malaria is still significant, the statistics reflect a considerable reduction in the global malaria burden. Since 2010, disease transmission has been reduced by 30 percent and mortality due to malaria has decreased by almost half.

Climate change is affecting disease-carrying mosquitoes and other insects

Author: Sarah Craig

mosquito

Insect-borne diseases — such as malaria, dengue, West Nile and the newly emerging chikungunya — infect a billion people every year; more than a million die each year and many more are disabled. The effects of climate change, according to Edwin Michael, professor of biological sciences and member of the Eck Institute for Global Health at the University of Notre Dame, mean these deadly diseases are no longer reserved for the developing world.

New paper examines social effects on the gut microbiome of wild baboons

Author: William G. Gilroy

Baboons

A new study led by Elizabeth Archie, Clare Boothe Luce Assistant Professor of Biology at the University of Notre Dame, has found that social interactions have direct effects on the gut microbiome.

Archie points out that most, if not all, animals have a gut microbiome — an incredibly diverse “rainforest” of bacteria that lives in the intestine and helps animals digest food, make vitamins and fight disease.

The study revealed that baboons that had closer social bonds had more similar gut bacteria than animals with weaker social ties.

New study reveals links between alcoholic liver disease and the circadian clock

Author: William G. Gilroy

liver

Researchers from the University of Notre Dame and the Indiana University School of Medicine have revealed a putative role for the circadian clock in the liver in the development of alcohol-induced hepatic steatosis, or fatty liver disease.

Hepatic steatosis is the abnormal accumulation of fats in the cells of the liver, and is linked to disturbed control of fat metabolism. Alcohol-induced liver steatosis is produced by excessive alcohol consumption and is linked to hepatitis, or inflammation of the liver.
