New research indicates that severe cases of COVID-19 or influenza can alter lung immune cells, potentially increasing cancer risk months or years afterward. The study, conducted by scientists at the University of Virginia, highlights the role of chronic inflammation in this process and emphasizes vaccination as a preventive measure. Findings suggest closer monitoring for affected patients to enable early detection.

Researchers at the University of Geneva have discovered that tumors can reprogram neutrophils, turning these immune cells from defenders against infection into promoters of cancer growth through the production of a molecule called CCL3. This finding, published in Cancer Cell, suggests CCL3 could serve as a marker for tracking tumor progression across various cancers. The study highlights how the tumor environment alters immune responses to favor disease advancement.

A new study reveals that breastfeeding leads to a long-term surge in specialized immune cells in breast tissue, potentially reducing cancer risk. Researchers found these CD8+ T cells persist for decades, acting as guards against malignant cells. The findings suggest breastfeeding could enhance natural protection against aggressive breast cancers.

Scientists have developed mRNA vaccines that produce virus-like nanoparticles inside cells, potentially offering more robust immune responses than current versions. In mouse studies, this approach generated antibody levels up to 28 times higher than standard mRNA vaccines. The innovation could reduce side effects by allowing lower doses while maintaining efficacy.
