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

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

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 ...

Aged and frail people often suffer a decline in tissue reserve capacity during aging. This reserve, called resilience, helps ...

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 ...

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 ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

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 ...

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 ...

In a person living with HIV, proviruses—strands of HIV DNA—are typically integrated into the T cell genome and become a ...

When you take a drug, where in your body does it actually go? For most medications, scientists can make only educated guesses about the answer to this question.
