Roundworm News and Research

RSS

Roundworm infection, or toxocariasis, is a zoonotic disease — a disease that can be transmitted from animals to humans. Dogs and cats are the definitive hosts for the roundworm species that commonly cause human disease.

Researchers discover protein that adjusts gene activity to match nutrient levels in roundworms

Transforming a fertilized egg into a fully functional adult is a complicated task. Cells must divide, move, and mature at specific times. Developmental genes control that process, turning on and off in a choreographed way.

Invasive alien species threaten biological diversity, shows study

The raccoon, raccoon dog, mink, and golden jackal are not native to Germany or Europe but are increasingly spreading in these non-native regions.

Study reveals key role of IL-33 signaling molecule in parasite infections, other health conditions

De'Broski Herbert has a philosophy that's guided his career researching helminths, or parasitic worms, and their interaction with their hosts' immune systems: "Follow the worm."

Oregon biologists reveal molecular mechanisms that produce DNA damage in sperm

University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.

PATH wins grant to develop oral treatment option for soil-transmitted helminth infections

PATH announced today they received a grant from Japan's Global Health Innovative Technology Fund to develop a new oral treatment option for soil-transmitted helminth infections.

Researchers demonstrate the utility of AI in identifying neural degeneration

Researchers from North Carolina State University have demonstrated the utility of artificial intelligence (AI) in identifying and categorizing neural degeneration in the model organism C. elegans. The tool uses deep learning, a form of AI, and should facilitate and expedite research into neural degeneration.

TRA-1 gene determines the sex of roundworms

Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex.

Study offers new possibilities for developing anti-aging drugs

KAIST researchers have been able to dial up and down creatures' lifespans by altering the activity of proteins found in roundworm cells that tell them to convert sugar into energy when their cellular energy is running low.

USC scientists may have found a path toward increasing human lifespan

Scientists at USC Dornsife College of Letters, Arts and Sciences may have found the beginnings of a path toward increasing human lifespan.

Diet and gut microbiome affect outcomes of chemotherapy

What we eat can affect the outcome of chemotherapy – and likely many other medical treatments – because of ripple effects that begin in our gut, new research from the University of Virginia suggests.

A new treatment option for activating cellular defenses against neurodegenerative disease

Talk about motherly instincts: Biologists at the University of Iowa have learned that female roundworms can alert their future offspring of dangers they will encounter when born, and the mothers pass on these warnings even before the offspring have been conceived.

KU Leuven study uncovers how signaling molecule plays key role in learning process

Neurobiologists at KU Leuven have discovered how the signalling molecule Neuromedin U plays a crucial role in our learning process.

Active ingredient from parasite larvae could help treat asthma

The larvae of the roundworm Heligmosomoides polygyrus bakeri (Hpb) need a very special environment in order to survive: They have to invade the mucosal layer of the intestine in rodents, the only place where they can then develop into adult worms capable of reproduction.

Sushi parasites increased over 280-fold in 40 years

A new study published in the journal Global Change Biology in March 2020 on the occurrence of certain worms in raw or undercooked seafood, in the form of sushi, sashimi, nigiri, etc., reports an increase in the number of parasites by over 280 times over the last 40 years. This could have dramatic effects on the health of both humans and marine mammals, both of which may accidentally ingest the worm.

Scientists discover new biological mechanism of insulin signaling

In a discovery that may further the understanding of diabetes and human longevity, scientists at Scripps Research have found a new biological mechanism of insulin signaling.

Researchers discover glial cells that control stress response, extend lifespan in worms

While many of us worry about proteins aggregating in our brains as we age and potentially causing Alzheimer's disease or other types of neurodegeneration, we may not realize that some of the same proteins are aggregating in our muscles, setting us up for muscle atrophy in old age.

MDI Biological Laboratory will use African turquoise killifish model to study aging

The study of therapies and interventions to expand healthy human lifespan has been limited by a lack of animal models: traditional vertebrate models such as the mouse live too long to get rapid results, while the most popular model, a roundworm called C.elegans that lives for only three weeks, is rungs away from humans on the evolutionary ladder.

Parkinson’s disease could be prevented by gut microbes

One common gut organism that helps us digest food better could also be a powerful instrument in preventing or reversing the symptoms of Parkinson’s disease (PD), according to a recent study. The changes are due to the ability of this bacterium to delay the build-up of a toxic protein involved in this in the disease condition, or even to eliminate the toxin altogether.

Common plasticizer leads to fertility problems in roundworms

A new study published 9th January in PLOS Genetics by Mónica Colaiácovo of Harvard Medical School and colleagues reports that the most commonly used plasticizer, diethylhexyl phthalate, leads to fertility problems by causing an excess number of breaks in the DNA during egg production, and then interfering with the repair systems that fixes the breaks.

One Health approach that targets both humans and animals can reduce costs

Promoting healthcare strategies that target both human and animal populations at the same time can save money, participant time and result in a two-for-one stop for health care services.
