Host defenses signal Salmonella to hijack immune cells, spur disease

Posted on February 12, 2021 by Amy McDermott

Immune cells attack dangerous bacteria by engulfing them and then releasing a cascade of defense molecules. But some bacteria, known as intracellular pathogens, have evolved to survive this onslaught and replicate inside immune cells. The result can be Salmonella poisoning … Continue reading →

Study reveals evolutionary origins of fold-switching protein

Posted on January 8, 2021 by Amy McDermott

Most proteins are thought to fold into a single active shape. But the human immune protein XCL1 is a rare breed that can switch back and forth between two different structures, each with its own function. A recent study in … Continue reading →

Study finds clues to Alzheimer’s disease onset in the aging female brain

Posted on December 11, 2020 by Stephen Ornes

In the United States, women make up nearly two-thirds of all diagnosed cases of Alzheimer’s disease. On average, women live about 5 years longer than men, but that life expectancy discrepancy doesn’t likely account for such a large, sex-skewed prevalence … Continue reading →

Fluid dynamics work hints at whether spoken word can spread COVID-19

Posted on April 7, 2020 by Carolyn Beans

As of April 3, the Centers for Disease Control and Prevention (CDC) is advising that everyone—sick or healthy—wear masks to prevent the spread of COVID-19. Recent research on how fluids travel from our respiratory tracts when we sneeze, speak, or … Continue reading →

New insights into how influenza evades human immunity

Posted on September 14, 2019 by Natasha Gilbert

Some viruses can only infect people once—measles for example. But other viruses, notably influenza, are capable of infecting repeatedly. Scientists have long puzzled over how the flu virus evades human immunity. Recent work in eLife clarifies exactly how the virus … Continue reading →

Journal Club: Tumors create an acidic environment that helps them invade surrounding tissues

Posted on March 29, 2019 by Jessica P. Johnson

Cancer cells tend to turn their extracellular environment acidic, thus helping these rogue cells thrive while creating a hostile environment for normal ones. Acidosis promotes tumor growth, metastasis and drug resistance, while helping tumor cells evade the immune system. But … Continue reading →

Journal Club: Amoeba have long-distance preference for certain bacteria, pointing to other cell-sensing insights

Posted on January 29, 2019 by Jessica P. Johnson

How does the microscopic amoeba track down prey in the vastness of the forest floor? Ample research on the soil amoeba Dicytostelium discoideum, affectionately called “Dicty” by researchers, has provided some clues. But the mechanisms behind long-distance sensing of bacterial … Continue reading →

Journal Club: Mutation helps Zika virus evolve to more easily infect mosquitoes, spread infection

Posted on June 16, 2017 by Carolyn Beans

Scientists discovered the Zika virus over half a century ago. But it wasn’t until recent outbreaks in French Polynesia and South America that the mosquito-borne virus, now associated with Guillain-Barre syndrome in adults and microcephaly in newborn babies, reached epidemic … Continue reading →
