Scientists manipulate 'signaling' molecules to control cell migration
Jun 30, 2017
Johns Hopkins researchers report they have uncovered a mechanism in amoebae that rapidly changes the way cells migrate by resetting their sensitivity to the naturally occurring internal signaling events that drive such movement. ...
Discovery of human blood cell destinies revises knowledge of immune cell development
Jun 15, 2017
Immune cells protect the host from infection by pathogens. They include monocytes, which are large white blood cells that can differentiate into scavenger cells macrophages and dendritic cells in response to inflammatory ...
Taking a closer look at genetic switches in cancer
May 22, 2017
Many things go wrong in cells during the development of cancer. At the heart of the chaos are often genetic switches that control the production of new cells. In a particularly aggressive form of leukemia, called acute myeloid ...
New nano-polymer could prevent heart failure
May 22, 2017
Researchers at Ben-Gurion University (BGU) and the Sheba Medical Center have developed a new therapy to treat atherosclerosis and prevent heart failure with a new biomedical polymer that reduces arterial plaque and inflammation ...
New cell separator with humble beginnings could revolutionise medical advances in cancer and Alzheimer's research
May 08, 2017
A new cell separator that began life as a tinfoil and epoxy glue prototype built with supplies from a University shop could revolutionise stem-cell and regenerative cell-based therapies.
Cancer-causing virus masters cell's replication, immortality
May 02, 2017
Viruses are notorious for taking over their host's operations and using them to their own advantage. But few human viruses make themselves quite as cozy as the Epstein-Barr virus, which can be found in an estimated nine out ...
Purifying cells to treat disease
May 01, 2017
Various cell therapies involve injecting a specific cell type into a patient. These include, for example, bone marrow transplants and some types of immunotherapy that use T-cells (a white blood cell involved in immunity) ...
Nanosponges lessen severity of streptococcal infections
Apr 24, 2017
In a new study, researchers show that engineered nanosponges that are encapsulated in the membranes of red blood cells can reduce the severity of infections caused by group A Streptococcus, the bacteria responsible for strep ...
Research spotlights early signs of disease using infrared light
Mar 21, 2017
University of Sydney researchers have used infrared spectroscopy to spotlight changes in tiny cell fragments called microvesicles to probe their role in a model of the body's immunological response to bacterial infection.
Researchers decipher how the body controls stem cells
Mar 15, 2017
Stem cells are unspecialised cells that can develop into any type of cell in the human body. So far, however, scientists only partially understand how the body controls the fate of these all-rounders, and what factors decide ...
