Researchers have discovered a new way that epithelial cells, which form layers in organs like the skin and stomach, attach to one another, and how they perceive growth signals at these attachments, ...

Objective Macrophages and kidney cell pyroptosis/ferroptosis could play an important role in the pathogenesis of lupus ...

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells -- which compose the linings of our skin, organs and body cavities -- are mute, ...

Northwestern Medicine scientists have discovered a previously unknown process used by epithelial cells to alleviate epithelial tissue crowding and avoid cell damage and loss, according to a recent ...

Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery networks. Lumens in the pancreas form a complex ductal system, and its ...

The classical concept of immune privilege as an exclusion of immune cells has been extended to include sites of immune tolerance induction, such as the intestine. Barriers can be grouped into three ...

Deep in the brain, sheets of tissue known as the choroid plexus produce cerebrospinal fluid (CSF) and act as a protective barrier between the brain and CSF. But the lab of Maria Lehtinen, Ph.D., at ...

The thymus is a crucial organ of the immune system. In the thymus, the well-known T cells mature: As killer cells, they recognize and destroy virus-infected or malignant cells, and as so-called helper ...

Your skin cells can generate electricity when wounded. Torsten Wittmann, University of California, San Francisco/NIH via Flickr, CC BY-NC Your cells constantly generate and conduct electricity that ...

Epithelial cells line various surfaces of the body, including the skin, blood vessels, organs, and urinary tract. A raised amount of epithelial cells in a person’s urine may indicate an underlying ...

Disease-related injury in any organ triggers a complex cascade of cellular and molecular responses that culminates in tissue fibrosis. Although this fibrogenic response may have adaptive features in ...
