A trio of mRNA molecules could help guard against the harmful effects of aging on immune cells, a study in mice finds.

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

Researchers have created an early map of some of the human body's estimated 37.2 trillion cells. Each type of cell has a unique role, and knowing what all the cells do can help scientists better ...

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 ...

Scientists mapped where drugs bind inside the body, cell by cell, to better understand benefits and side effects.

MIT researchers are using living cells to target diseased brain areas and deliver tiny electronic devices that can modulate ...

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 ...

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 ...

In a person living with HIV, proviruses—strands of HIV DNA—are typically integrated into the T cell genome and become a permanent part of the cell's genetic makeup. This integration enables the ...

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 ...

How cells become cancerous is a process researchers are still trying to fully understand. Generally, normal cells grow and multiply through controlled cell division, where old and damaged cells are ...

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 ...
