Host heterogeneity increases pathogen virulence in metapopulations

Heterogeneity is ubiquitous in real-world host populations, yet most theories assume homogeneity. Using a metapopulation model, we examine how host heterogeneities, such as uneven movement patterns and local productivities, affect the evolution of pathogen virulence.

Long-term green tea catechins prevent aging-related cardiac dysfunction

A new publication from Genes & Diseases; DOI 10.1016/j.gendis.2024.101284, discusses the effect of long-term administration of green tea catechins on aging-related cardiac diastolic dysfunction and decline of troponin I.

Cellular RNA enhances MAVS signalosome activation in antiviral immunity

Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune responses against virus invasion.

Study reveals significant improvements in the health of older adults in England

A new study from the Robert N. Butler Columbia Aging Center at the Mailman School of Public Health reveals significant improvements in the health of older adults in England when compared to previous generations.

Breakthrough in antigen recognition: TRACeR-I enhances immune targeting

Researchers describe TRACeR-I, a protein platform that can be used to engineer immune responses.

Decoding sleep disorders through fairy tales

Some traditional fairy tales and classic children's fiction that have soothed many a child to sleep may also provide accessible and engaging ways to discuss healthy sleep with children, suggest researchers in the Christmas issue of The BMJ.

Hippocampal inflammation affects behavior differently in males and females

Inflammation in the hippocampus – the brain's memory centre – significantly alters motivation and behavior in mice, including food-seeking behaviour, with notable differences between males and females, a recent study reveals.

Trump’s picks for top health jobs not just team of rivals but ‘team of opponents’

Many of President-elect Donald Trump's candidates for federal health agencies have promoted policies and goals that put them at odds with one another or with Trump's choice to run the Department of Health and Human Services, Robert F. Kennedy Jr., setting the stage for internal friction over public health initiatives.

Nutrient metabolism regulates T cell exhaustion and therapy potential

Findings reveal that metabolic enzymes ACSS2 and ACLY regulate T cell exhaustion, linking nutrient metabolism to epigenetic changes in immunity.

Breakthrough discovery could lead to effective vaccine for S. aureus

Staphylococcus aureus (S. aureus) is a major cause of skin and soft tissue infections that can sometimes lead to sepsis and toxic shock syndrome.

Disrupting the circadian rhythm of glioblastoma slows tumor growth, study says

Virtually every cell in the human body has an internal clock. These clocks take their cues from a central clock in the brain. In a normal, biological process called synchrony, the central clock coordinates daily rhythms around the body, so that every cell and tissue recognizes the same external time of day.

A genetic variant modulates interferon signaling and disease risk

For years, scientists have looked to a critical piece of immune system machinery - known as the interferon pathway - for answers. There, when our cells sense an infection, they release a protein known as interferon, which warns other cells to fight the virus.

Skin as an immune hero: Fighting infections with self-made antibodies

Researchers uncover how the skin autonomously produces antibodies through specialized immune structures, maintaining microbial balance and preventing infections.

New hepatitis B vaccine offers superior protection for people with HIV

A newer vaccine against hepatitis B virus was clearly superior to an older vaccine type in inducing a protective antibody response among people living with HIV who didn't respond to prior vaccination, according to the results of an international study led by a Weill Cornell Medicine investigator.
