Harnessing the Power of Beneficial Bacteria to Fight Enterobacteriaceae

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enterobacteriaceae are a common cause of these infections and have few treatment options. Fecal microbiota transplants have shown promise to curb some of these infections, but their composition varies between batches and they aren't always successful.

Study Reveals Immune Cells' Role in Lung Scarring After Viral Infections

Investigators involved in a multicenter study co-led by Cedars-Sinai discovered a pathway by which immune cells prevent the lungs' protective barrier from healing after viral infections like COVID-19.

Atypical B Cells Play a Central Role in COVID-19 Vaccine Response

Vaccines function by strengthening defenses against viruses that invade human bodies. Vaccination against COVID-19 teaches the human immune system's specialized B cells how to identify the virus.

Climate Change Exacerbates Valley Fever Threat

A fungal disease called valley fever is on the rise in the western United States. It typically manifests as flu-like symptoms, but it can potentially have fatal or extremely serious side effects.

Inflammation-Induced Epigenetic Changes Limit Intestinal Stem Cell Regeneration

Researchers from the University of Michigan, Baylor College of Medicine, and other affiliated institutions have found that intestinal stem cells (ISCs) are permanently altered by inflammation in the gut, which limits the cells' capacity to repair the gut even after the inflammation has subsided.

New Insights into Mosquito Mating Could Enhance Malaria Control Strategies

A high-pitched buzzing sound in your ear is an unmistakable sign that a female mosquito is out on the hunt -; for they, not males, drink blood. Hearing that tone might make you turn to try to swat the pest. But for a male mosquito, that tone means it's time to mate.

New Study Reveals Antibiotic Mismanagement in Aged Care Facilities

There is an urgent need for more careful antibiotic management to protect older people living in residential aged care from the dangerous spread of antibiotic-resistant bacteria or 'superbugs', researchers from Flinders University and SAHMRI warn.

Study Identifies Key Macrophage Subpopulations in MASH Progression and Regression

Formerly known as nonalcoholic steatohepatitis, metabolic dysfunction-associated steatohepatitis (MASH) is an inflammatory disease characterized by liver scarring or fibrosis that progressively impairs liver function.

New Research Reveals Infrared Radiation as a Mosquito Host-Seeking Trigger

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases of dengue, yellow fever, Zika, and other diseases every year. Another, Anopheles gambiae, spreads the parasite that causes malaria. The World Health Organization estimates that malaria alone causes more than 400,000 deaths every year. Indeed, their capacity to transmit disease has earned mosquitoes the title of deadliest animal.

The Complex Link Between DNA Modification and ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease which remains incurable. The disease is characterized by the selective degeneration of upper motor neurons in the motor cortex as well as the lower motor neurons in the brainstem and spinal cord. The cause of ALS remains unknown in 90 percent of cases, which are referred to as sporadic ALS because there is no family history for the disease. Cumulative evidence suggests that sporadic ALS may result from complex interactions between genetic susceptibility and aging.

Geographic Origin Plays Key Role in Tuberculosis Infection, Harvard Study Finds

For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a new study comparing how different strains move through mixed populations in cosmopolitan cities.
