Researchers discover a mechanism that leads to the growth of cell nuclei

By far the most important process in cell development is how cells divide and then enlarge in order to multiply. A research team headed by Freiburg medical scientist Prof. Dr. Robert Grosse has now discovered that bundled fibers of actin within a cell nucleus play an important part in how they enlarge after division.

Star-shaped brain cells are essential for blood-brain barrier health, shows study

Hard skulls help protect our brains from physical injuries.In addition to a tough outer shell, brains have internal defenses, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is breached, then health problems arise.

Study helps explain how Treg cells prevent autoimmunity, dampen immune responses

In a new University of California, Irvine-led study, researchers have discovered how regulatory T cells (Treg) are instrumental in limiting the damage caused to the spinal cord in diseases like multiple sclerosis (MS).

Proteins act as compasses to guide stem cell division in plants

The stem cells tasked with creating and maintaining biological tissues have a difficult job. They have to precisely divide to form new specialized cells, which are destined to different fates even though they contain identical DNA. An obvious question then is: How do the cells divide in all the right ways to produce a healthy tissue?

Protein in the pancreas protects beta-cells from high-fat diet induced stress

Every time we eat, the glucose level in our body goes up. This spurs our pancreatic machinery into action and through intricate physiological mechanisms, appropriate amounts of insulin are produced, our blood glucose levels are controlled, and we remain healthy.

T cells play a vital role in controlling SARS-CoV-2 during acute phase of infection

Ever since SARS-CoV-2 first appeared, researchers have been trying to understand whether sometimes the immune system does more harm than good during the acute phase of COVID-19. The latest study by researchers at La Jolla Institute for Immunology clearly argues in favor of the immune system.
