The mammalian immune system is an evolutionary wonder. It’s capable of recognizing and destroying cancer cells, and it can deploy armies of antibodies against viruses, bacteria, parasites and fungi.

Among the lesser-spotlighted roles of the immune system is how a particular T cell helps maintain homeostasis—fostering a balanced and stable metabolic environment—in fat cells. It’s a role that has captured the investigatory eye of an elite team of immunologists.

Having a stronger understanding of the dynamic metabolic activities and signaling pathways in fat tissue can aid new strategies to treat obesity, a major global health concern...

Experimental Therapy Eases Alzheimer’s Signs, Symptoms in Mice

Experimental therapy eases alzheimer's signs, symptoms in mice
A new cellular therapy improved learning and memory in mice with Alzheimer’s disease, researchers report.

The therapy—developed at the University of Nebraska Medical Center (UNMC)—relies on both the immune system to fight key aspects of Alzheimer’s, plus modified cells that zero in on the brain protein plaques that are a hallmark of the disease.

In patients with Alzheimer’s, amyloid-beta protein forms plaques that prevent nerve cells from signaling each other. One theory is that this might cause irreversible memory loss and behavior changes characteristic of Alzheimer’s disease.

The new study was recently published in the journal Molecular Neurodegeneration. Researchers used genetically modified immune-controlling cells called Tregs to target amyloid-beta.

When the UNMC te...

Some benefits of Exercise stem from the Immune System, suggests new study

The hind leg muscles of mice lacking Treg cells (right) showed prominent signs of inflammation after regular exercise, compared with those of mice with intact Tregs (left). The research showed that this uncontrolled inflammation negatively impacted muscle metabolism and function. Images: Kent Langston/Mathis Lab, HMS

The connection between exercise and inflammation has captivated the imagination of researchers ever since an early 20th-century study showed a spike of white cells in the blood of Boston marathon runners following the race.

Now, a new Harvard Medical School study published in Science Immunology may offer a molecular explanation behind this century-old observation.

The study, in mice, suggests that the beneficial effects of exercise may be driven, at least partly, by ...

New Breakthrough to Help Immune Systems in the Fight against Cancer

Cancer cell

New research has identified potential treatment that could improve the human immune system’s ability to search out and destroy cancer cells within the body. Scientists have identified a way to restrict the activity of a group of cells which regulate the immune system, which in turn can unleash other immune cells to attack tumours in cancer patients.

“A patient’s immune system is more than able to detect and remove cancer cells and immunotherapy has recently emerged as a novel therapy for many different types of cancers.” Explained Nullin Divecha, Professor of Cell Signalling at the University of Southampton who led the study...
