Researchers at the National Institutes of Health (NIH) have found a way to boost cell immunity. This could lead to a new treatment for pneumonia.

Scientists have come up with a new alternative to antibiotics that stop working effectively – these are artificial molecules that stimulate human immunity.

Decades of overuse of antibiotics have resulted in many types of bacteria developing resistance to these drugs. Such a health crisis could claim 10 million lives annually by 2050.

The authors of the new work investigated a compound called epoxy cosatrienoic acid (EETS). It performs a regulatory function in the body, limiting inflammation.

Regardless, the body suppresses EETS during infections so that immune cells can take action. The authors tried to block EETS even more using a synthetic molecule called EEZE.

The team tested the molecule in mice infected with Streptococcus pneumoniae, the bacteria that commonly causes pneumonia. It worked. The number of bacteria in the lungs of rodents has decreased significantly. These new molecules can be used in an inhaler or in pill form to help kill bacteria.
