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 ...

An international group of researchers has identified an important mechanism that enables stem cells to evade immune rejection. Their research, published in Nature, sheds light on how these specialized ...

The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that ...

Immunologists have uncovered new approaches to enhance protection from tumors and infections. They have revealed new insights into the metabolism of specialized cells of the immune system known as ...

The cells of all animals—including humans—are characterized by their ability to adhere particularly well to surfaces in their ...

Salk researchers report they have discovered a protein called Mitf that mediates the repair function in the peripheral nervous systems of mice. The protein Mitf helps turn on the repair function of ...

Cells are the smallest unit of life. Cells in multicellular plants and animals are arranged into tissues, organs and organ systems. Cells. Tissues. Organs. Organ systems. And the organism itself.

Scientists have made an important discovery about the relationship between hematopoietic stem cells (HSCs) and immune response evasion. Their findings show how certain HSCs have regulatory functions ...
