Immune microRNAs drive new frontiers in cardiovascular disease research

  Cardiovascular diseases (CVDs) continue to dominate global mortality statistics, with immune dysregulation emerging as a central feature in their pathogenesis. This review by Gareev et al. focuses on immune-derived microRNAs (immuno-miRs) as pivotal modulators of immune responses in cardiovascular settings, highlighting their roles in pathophysiology, diagnostic potential, and therapeutic promise. Introduction … Read more

Targeting astrocytes could boost immunotherapy effectiveness in glioblastoma

Q: How would you summarize your study for a lay audience? Our study investigated the role of astrocytes, an abundant cell type in the brain, in regulating an immune response against glioblastoma (GBM)-a highly aggressive brain cancer. We found a subset of astrocytes that limits the immune response and can be targeted with therapeutics. Q: … Read more

JAX study sheds light on infection vulnerability in patients with rare mitochondrial diseases

Patients with rare mitochondrial diseases already face a host of serious health issues, from muscle weakness to neurological problems and heart conditions. But one of their most life-threatening challenges has remained a mystery-why are they so vulnerable to severe infections? Now, scientists at The Jackson Laboratory (JAX) may have finally pinpointed why. Their new study, … Read more

Researchers identify key cells behind peanut allergy prevention

A decade ago, a clinical trial in the U.K. famously showed that children who were exposed to peanuts in the early months of life had reduced risk of developing a peanut allergy compared with children who avoided peanuts. Now, researchers at Memorial Sloan Kettering Cancer Center (MSK) have a likely answer as to why that’s the case: … Read more

Researchers find immune system proteins involved in severe cases of schistosomiasis

New insights into the mechanisms that cause more severe cases of schistosomiasis – a disease caused by parasitic worms and second only to malaria in terms of potential harm – have been revealed by researchers at Penn State. The study – which took place in mice and was published in PLOS Pathogens -used a mouse model to examine how the … Read more

High fiber diet helps protect against dangerous gut infections

A study published in the journal Cell Host & Microbe by Brazilian and American researchers suggests that a diet rich in soluble fiber can protect the intestine against pathogenic bacteria. The conclusion is based on experiments with mice exposed to Clostridioides difficile, which causes colon inflammation and diarrhea and affects about 500,000 people a year in the United States. “We were able … Read more

Switching to a Western diet triggers inflammation and weakens immunity

A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Conversely, an African diet rich in vegetables, fiber, and fermented foods has positive effects. This study, published in Nature Medicine, highlights the significant impact of … Read more

New insights into how the immune system handles latent parasite infections

Most humans have long-lived infections in various tissues-including in the nervous system-that typically do not result in disease. The microbes associated with these infections enter a latent stage during which they quietly hide in cells, playing the long game to evade capture and ensure their own survival. But a lack of natural models to study … Read more
