Every person who has ever been pregnant leaves a biological trace that is far more intimate than a family photo album. During ...

A New York University study has found that kidney and nerve tissue cells can form memories much like brain cells. According to the study authors, their findings could help researchers better ...

Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein ...

As the body ages, organ function progressively declines and the risk for a wide range of diseases, including cardiovascular disease, cancer and neurodegenerative diseases, increases. Understanding how ...

KAIST researchers have developed a way to reprogram immune cells already inside tumors into cancer-killing machines. A drug ...

In a recent study published in the journal PNAS, researchers examined the relationship between cell size and count across the human body, establishing a quantitative framework and uncovering ...

Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable ...

The immune system provides constant surveillance for the body, aiming to spot and eliminate disease-causing microbes or ...

CD4+ T cells, or helper T cells, are one type of lymphocyte that helps coordinate the immune response against infection and disease. They interact and activate other cells in the immune system. The ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...
