Immune System News -- ScienceDaily

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 nucleic acids. The Fusion Visualization system 2 cell l…

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 liver.

The COVID-19 virus can persist in the blood and tissue of patients for more than a year after the acute phase of the illness has ended, according to new research that offers potential clues to why some people develop long COVID.

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 study shows. The same findings also support experimenta…

Researchers have shown that sleep enhances the migratory potential of T cells toward lymph nodes.

COVID-19 vaccines elicit strong T-cell responses, but clonal-resolution analyses of these responses have not previously been performed. To address this gap, a team of researchers investigated the T- cell receptor sequence and tracked it using trammer a…

A team of researchers has successfully modified a naturally occurring chemical compound in the lab, resulting in advanced lead compounds with anti-HIV activity.

Medical researchers have identified the means in which bacteria in the digestive system can break down tryptophan in the diet into an inflammatory chemical that primes the immune system towards arthritis.

A recently published study that shows lactating mothers who get the COVID-19 booster pass along the antibodies to their children via their breast milk — and potentially protect babies too young to receive the vaccine.

T follicular helper cells (Tfh) are essential for strong antibody-mediated reactions of our immune system during infections and vaccinations. However, if they get out of control, this can cause diseases such as autoimmunity, allergies or cancer. Resear…
