Discovery of a new cellular element crucial to sense of smell

Researchers at Umeå University have found an organelle, a previously unidentified cellular component, inside the neurons that are responsible for the ability to smell. The finding might have repercussions for future studies on COVID-19 symptoms like impaired smell sense.

RXR: A key protein in the balanced production of different blood cells

In the regulation of hematopoietic stem cells—which are the immature stem cells that produce all the blood cell lineages—the cell protein retinoid X receptor (RXR) is an important element.

The potential of cellular “glue” in regenerative medicine

Scientists at UC San Francisco have created molecules that function as “cellular glue,” enabling them to precisely control how cells adhere to one another. The discovery is a significant step toward regenerative medicine’s long-term goal of creating new tissues and organs.

Scientist honored for his contribution on ALS research

The Drs Ayeez and Shelena Lalji & Family ALS Endowed Award for Innovative Healing was given to Clive Svendsen, PhD, a pioneer in regenerative medicine, for his significant contributions to the field of amyotrophic lateral sclerosis (AL) at Massachusetts General Hospital’s Sean M. Healey & AMG Center for ALS.

Molecular regulation underlying emergency hematopoiesis uncovered

If the body’s emergency hematopoiesis program activates, it signifies an alert state of the immune system and serves two functions: In comparison to “normal mode” hematopoiesis, the emergency program results in enhanced replacement of immune cells consumed during infections or inflammations.

Scientists identify the long-sought CO2 sensor in Arabidopsis plants

More than 50 years, ago researchers discovered that plants can sense carbon dioxide (CO2) concentrations. As CO2 levels change, "breathing" pores in leaves called stomata open and close, thus controlling evaporation of water, photosynthesis and plant growth.

New 3D organoid model reveals a possible biological target for treating GEJ cancers

Researchers at Johns Hopkins Medicine say they have created a laboratory-grown three-dimensional "organoid" model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point where the digestive system's food tube meets the stomach.

Research could advance our understanding of evolution and the origins of cell motility

The origin of all biological movements, including walking, swimming, or flying, can be traced back to cellular movements; however, little is known about how cell motility arose in evolution.

Figuring out how immune cells prevent cognitive decline

Could Alzheimer’s disease and other types of cognitive decline be caused by the underproduction of immune cells that are poorly understood? It might, according to a Rutgers study published in Nature Immunology, and increasing these cells could undo the harm.

Using nanotechnology and magnetic manipulations to bioengineer 3D neural networks

Neurons are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.
