Researchers have revealed how a common bacterium, Enterococcus faecalis (E. faecalis), releases lactic acid to acidify its surroundings and suppress the immune-cell signal needed to start a proper ...

The immune system regulates disease response throughout our bodies. Interestingly, two separate responses act as barriers to prevent the spread of infections. When first introduced to a disease, the ...

Discovered in 1964 by Anthony Epstein, Yvonne Barr, and Bert Achong, the Epstein-Barr virus (EBV) has intrigued tumor virologists due to its unique behavior. Typically, EBV establishes a lifelong, ...

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.

Lingering inflammation from viruses like COVID-19 or HIV can take a lasting toll on the brain. New research shows exactly how specific immune system imbalances lead to memory lapses and slowed ...

Researchers at Baylor College of Medicine and collaborating institutions have discovered a mechanism that drives the long-term decline in immune response that is observed after tuberculosis (TB) has ...

Researchers at the Kennedy Institute of Rheumatology have found that physically resisting the formation of an immunological synapse actually promotes a stronger immune response. The findings could ...

Virtual memory T cells (T VM), activated by IL-4 during a parasitic infection in the intestine, expressing the CD22 receptor, which enables them to regulate this activation. Researchers at the ...

The concept of vaccination was first developed in the 19th century when Dr. Edward Jenner made the observation that milkmaids were immune to a deadly virus known as smallpox. He realized that most ...

Sepsis and severe pneumonia are frequently accompanied by disruption of the gut microbiota, leading to immune dysfunction and ...
