Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early ...
Antibody responses to new SARS-CoV-2 variant infections and vaccinations are powerfully shaped by prior exposures to earlier SARS-CoV-2 vaccines, according to a new ...
A new study reveals that immune cells in the liver react to high cholesterol levels and eat up excess cholesterol that can otherwise cause damage to arteries. The findings suggest that the response to the onset of atherosclerosis begins in the ...
Insights into the workings of an immune cell surface receptor, called PD-1, reveal how treatments that restrict its action can potentially be strengthened to improve their anticancer effect, a new ...

Cells possess an innate immune system that defends against invasive pathogens. Previous studies have mapped out the cytoplasmic cGAS-STING pathway in the cytoplasm, known for responding to foreign ...

The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new ...

Scientists uncover the mechanism by which cells mark the protein cGAS for degradation, which is critical in preventing the immune system from mistakenly attacking the body's own ...

Researchers found that precancerous colon cells can avoid immune detection by turning on a gene called SOX17, which allows them to become essentially invisible to the immune ...

Researchers recently released a first-of-its-kind study that focuses on the rare autoimmune disorder aplastic anemia to understand how a subset of cells might be trained to correct the overzealous ...

Scientists have long believed that a newborn's immune system was an immature version of an adult's, but new research shows that newborns' T cells -- white blood cells that protect from ...

A new study identified a set of 140 genes that may help predict enhanced disease-free survival in patients with non-small cell lung cancer (NSCLC) treated with a combination of immunotherapy and ...

Recent developments in cancer research have highlighted the vital role of the immune system, particularly in the notable successes of cancer immunotherapy. Now, a paradigm-shifting study sheds light ...

Could the TB vaccine be a new immunotherapy for liver cancer? A study found that the century-old vaccine reduced tumors and extended survival for mice with liver ...

Immune cells must learn not to attack the body itself. A team of researchers has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the ...

Cycles of a diet that mimics fasting can reduce signs of immune system aging, as well as insulin resistance and liver fat in humans, resulting in a lower biological age, according to a new ...

Scientists have discovered that the immune system stalwart I B has a moonlighting gig. A tiny protein sequence within I B activates another family of key immune proteins called POUs. The discovery ...

Biomedical engineers have developed a technique that uses inhalation of exosomes, or nanobubbles, to directly deliver IL-12 mRNA to the lungs of ...

The number of ME/CFS patients is expected to rise drastically due to long-term effects of the COVID-19 pandemic. Scientists have now identified possible biomarkers that could improve the diagnosis ...

Using specially-developed nanobodies that bind to SPNS2 and enlarge the entire structure, the enlarged SPNS2 structure allows the S1P molecules to be viewed via cryogenic electron microscopy. ...

Scientists have long thought of the fluid-filled sac around our lungs merely as a cushion from external damage. Turns out, it also houses potent virus-eating cells that rush into the lungs during flu ...

Researchers have unveiled a detailed understanding of immune responses in cancer, marking a significant development in the field. Utilizing data from more than 1,000 tumors across 10 different ...

Like other factors such as age, sex and genetics, smoking has a major impact on immune responses, according to a new study. In addition to its short-term impact on immunity, smoking also has ...

Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help ...

A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far ...
