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.

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.

Improving potential of cellular therapies with CAR T therapy

CAR T cells, or engineered immune cells, have demonstrated to the world the potential of customized immunotherapies to treat blood cancers. Researchers have just released highly encouraging preliminary data for CAR T therapy in a small group of lupus patients.

Launch of stem cells into space to investigate stem cell aging

Lab tests on astronaut Scott Kelly’s blood cells after he returned from a year-long stay aboard the International Space Station (ISS) showed telomeric and pre-leukemic changes.

A gene’s function in embryonic development

An international study led by the medical school at the University of Bonn has discovered a gene that is crucial to the growth of the human embryo. Abnormalities of different organ systems may occur if it is changed.

Uncovering a cell-intrinsic mechanism to regulate cell population sizes

A new cell-intrinsic mechanism has been unraveled by scientists at the University of Basel. This regulates the correct number of T cells present in the organism and thus guarantees that the immune system functions in a proper manner.

Genetic timestamping tracks the fate of plasma cells over time

Vaccines function by effectively producing immune cells that live for a long time, frequently for decades. These immune cells form a protective barrier that prevents or reduces re-infection, as well as a memory that enables one to identify an old invader, such as a virus, and eliminate it before it causes disease.

Pioneering gene editing approach could lead to new treatments for CTLA-4 insufficiency

A fault in cells that form a key part of the immune system can be repaired with a pioneering gene editing technique, finds new research demonstrated in human cells and mice, led by UCL scientists.

Researchers discover cancer cells move to sweet spot conditions, likely to enable stronger traction

Cancer cells can be drawn to certain mechanical “sweet spot” conditions, according to a global team of researchers headed by University of Minnesota Twin Cities engineers.

Vienna researchers aim to solve a great mystery of human evolution

Using the latest scientific methods, Tom Higham and Katerina Douka from the University of Vienna want to solve a great mystery of human evolution: Why are we the only humans left? Higham and Douka were the first ones to find a first-generation offspring of two different types of human. They continuously publish new results in high impact journals, most recently in Science Advances.

Drugs used for myelodysplastic syndrome could potentially activate a sleeping oncogene

Hypomethylating agents (HMA) are currently used as a first-line treatment for patients with myelodysplastic syndrome (MDS) - a group of disorders where there is insufficient production of healthy mature blood cells in the bone marrow - and increasingly in other diseases, but their mechanism of action remains unclear.
