Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

New research reveals that aging immune cells can become locked in a self-sustaining inflammatory state, worsening the body’s ability to respond to severe infections.

Stress and broken sleep do not just leave people groggy, they quietly chip away at the very immune cells that keep infections ...

As the immune system weakens with age, researchers have found a way to temporarily boost its function by reprogramming liver cells to support T-cell development.

In recent years, the field of immunology has increasingly focused on the role of glycolipids and sphingolipids in the differentiation and function of innate immune cells, such as macrophages, ...

As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA ...

One of the main changes is a loss of the innate immune system's naive T cells, the first line of defense against pathogens, and an increase in the adaptive immune system's memory T cells. This ...

Many diseases affect men and women differently. Asthma tends to strike men earlier in life, yet more women develop asthma as they get older. Parkinson's is more common in men, but Alzheimer's is more ...

As we age, our immune system quietly loses its edge, and scientists have uncovered a surprising reason why. A protein called ...
