Biologists have now identified a mechanism that the immune system uses to eliminate genetically imbalanced cells from the body.

Bits of a protein that builds up in Parkinson’s disease trigger the immune system, causing it to tag them as foreign invaders.

Research shows that human immunity develops much earlier than previously thought, but functions differently in adults.

Combining the kinase inhibitor ibrutinib with an investigational personalized cellular therapy known as CTL119 can lead to complete remission in patients with high-risk chronic lymphocytic leukemia (CLL), according to new research.

Lactobacillus parafarraginis metabolites hindered the growth of multiple, distantly related bacterial pathogens.

The quirkiest organ in the human body may be a large sheet of fat that stretches over the intestines, liver, and stomach like an elastic apron. Sometimes called the 'policeman of the abdomen,' the omentum is known to secrete hormones related to obesity, and we're still learning new information about its functions. In a review, researchers discuss how the omentum is also an important immune organ.

With the new FISH-Flow protocol, researchers are able to evaluate multitudes of cells at once for telltale mRNA species and proteins. The blended procedure provides a chance to see how multiple kinds of immune cells are responding to a foreign substance, making it possible to detect the presence of disease faster and earlier.

While studying the underpinnings of multiple sclerosis, investigators came across important clues for how to treat a very different disease: cancer. Researchers describe an antibody that can precisely target regulatory T cells which in turn unleashes the immune system to kill cancer cells. The team reports that the antibody decreased tumor growth in models of melanoma, glioblastoma and colorectal carcinoma, making it an attractive candidate for cancer immunotherapy.

Researchers say they have identified a new way that cells in the brain alert the rest of the body to recruit immune cells when the brain is injured. The work was completed in mouse models that mimic infection, stroke or trauma in humans.

A surprising new study suggests they are also essential for the heart to beat normally. That could make macrophages prime targets for treating conditions like arrhythmias, in which the heart beats erratically.
