Unlocking the potential of double negative memory B cells in cancer treatment

University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center scientists have discovered a novel subset of cancer-fighting immune cells that reside outside of their normal neighborhood – known as the tertiary lymphoid structure – where they become frustratingly dysfunctional when in close contact with tumors.

Infant exposure to herpes virus may cause memory problems later in life

Very early exposure to even a very small dose of herpes simplex virus (HSV) in infant mice can lead to cognitive decline later in life, according to findings from a new Dartmouth-led study, in collaboration with Harvard Medical School and published in the journal PLoS Pathogens.

Lower vitamin B12 levels could impact brain function in older adults

Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough – particularly if you are older. It may even put you at risk for cognitive impairment.

Hospital sink drains found to harbor dangerous antibiotic-resistant bacteria

We hope to be cured when we stay in hospital. But too often, we acquire new infections there. Such 'healthcare-associated infections' (HAI) are a growing problem worldwide, taking up an estimated 6% of global hospital budgets.

Infants with cystic fibrosis show stunted gut microbiome development

Findings from a new Dartmouth-led study, published in the journal mBio, highlight key differences in the gut microbiome (communities of bacteria) of infants with cystic fibrosis (CF) compared to that of healthy infants, and how these alterations may adversely affect their health.

Study highlights the need for more diversity in vaginal microbiome research

This study emphasizes the need for global equity in vaginal microbiome research, addressing health disparities and improving female health strategies worldwide.

Addressing the global challenge of bacterial STIs

According to the World Health Organization (WHO), hundreds of millions of new cases of bacterial sexually transmitted infections (STIs) are reported worldwide each year. Many infections go undiagnosed due to their often silent symptoms, contributing to transmission, disease and complications such as infertility and miscarriage.

Rethinking red meat: Are dietary guidelines missing the bigger picture?

Research highlights the critical role of red meat in providing essential nutrients like iron, zinc, and B12, particularly for vulnerable populations, while questioning the low-certainty evidence linking it to chronic diseases. It urges policymakers to balance health, environmental, and economic factors when considering dietary guidelines.

Diabetes plays key role in the emergence and expansion of antibiotic resistance

Antibiotics are powerful, fast-acting medications designed to eradicate bacterial infections. However, in recent years, their dependability has waned as antibiotic resistant bacteria continues to evolve and spread.

Global study reveals diversity in healthy vaginal microbiomes

Seeking to understand what constitutes a healthy vaginal microbiome, a global research collaboration that includes a Rutgers-New Brunswick scientist has reported a series of findings, including identifying which bacteria thwart vaginal disease and determining that microbiomes vary significantly across human populations.

Gut microbes influence how well cancer patients respond to immunotherapy

Researchers discovered that gut microbiota-derived hexa-acylated LPS enhances the effectiveness of anti-PD-1 cancer immunotherapy, while penta-acylated LPS may suppress immune responses.

Influenza A virus changes shape to evade immune responses

Influenza A virus particles strategically adapt their shape-to become either spheres or larger filaments-to favor their ability to infect cells depending on environmental conditions, according to a new study from National Institutes of Health (NIH) scientists.
