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.
A new study published in Nature Cell Biology by Mark Alkema, PhD, professor of neurobiology, establishes an important molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
Researchers investigating the growth of a roundworm discovered a tiny RNA molecule that controlled the expression of specific genes in the early 1990s. This resulted in the discovery of microRNAs (miRNAs), which are now known to exist in all forms of life. These molecules, it turns out, play vital functions in a variety of biological processes.
The University of Hong Kong (HKU) School of Biological Sciences research team led by Dr. Gary Ying Wai Chan has uncovered the function of a unique enzyme called ANKLE1.
A startling discovery that challenges the conventional wisdom that the majority of the hereditary information for cell differentiation is encoded within DNA and other genetic factors has been made regarding how specific proteins within the chromosomes of roundworms facilitate their offspring to develop specialized cells generations later.
Researchers have built the first ever map showing every single neuron and how they’re wired together in the brain of the fruit fly larva.
An inflammation and a rise in mucus production are typical signs of allergies and worm infections. The innate immune cells are involved in this immunological response, although it is still unclear exactly what they do.
A novel technique for identifying the genes that are important for aging has been discovered by scientists at North Carolina State University.
The mechanisms underlying sex determination in nematodes, commonly known as roundworms, have not been fully understood.
Researchers at UT Southwestern have uncovered a molecular path that allows cells to detect when their lipid supplies are running low, triggering a flurry of activity that avoids starvation.
Age-related changes in strength and mobility may depend on genetic variations in a critical mitochondrial enzyme, suggests a study published today in eLife.
Salk researchers have programmed mammalian cells to be stimulated with ultrasound.
Scientists from KAIST put forth novel insights for enhancing the health span by controlling a protein’s activity.
Scientists from the Francis Crick Institute unraveled a basic role of glial cells in the nervous system of the gut in retaining a healthy intestine.
When an organism encounters a threat in its environment, it is to the species' advantage to warn others of the peril.
Modern genetic research often works with what are known as reference genomes. Such a genome comprises data from DNA sequences that scientists have assembled as a representative example of the genetic makeup of a species.
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.
Cheating mitochondria can exploit cellular mechanisms for dealing with the scarcity of food in a worm, although this can decrease its wellbeing
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.
Scientists have successfully dialed up and down the lifespan of creatures by changing the activity of proteins present in roundworm cells.
As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances.
