Researchers at The Jackson Laboratory and UConn Health are rigorously investigating why vaccines don’t work as well in some older adults.

A research team has detected various substances that have a dual effect against tuberculosis: They render the bacteria causing the disease less pathogenic for human immune cells and boost the activity of conventional antibiotics.

A bioengineered "supercharged" immune cell has been designed that is particularly efficient at targeting and destroying cancer cells.

The preventative antibody shot niresvimab protects against hospitalization of infants infected with respiratory syncytial virus (RSV), according to results from a new clinical trial.

The world’s first partial heart transplant has achieved what researchers have spent more than a year hoping for -- functioning valves and arteries that grow along with the young patient.

Widely adopting RSV vaccines, similar to annual flu shots, would dramatically reduce the burden of illness and death in the over 60s, reports a new study.

The research team has successfully developed unprecedented “NK cell-engaging nanodrones” capable of selectively targeting and eliminating cancer cells, offering a potential solution for intractable types of cancers.

Messenger RNA (mRNA) is translated into proteins in the cytoplasm of cells. But rather than being a uniform “soup,” the cytoplasm is divided into multiple distinct compartments or regions.
