Researchers discover important drug target for preventing blood cancer

An international coalition of biomedical researchers co-led by Alexander Bick, MD, PhD, at Vanderbilt University Medical Center has determined a new way to measure the growth rate of precancerous clones of blood stem cells that one day could help doctors lower their patients' risk of blood cancer.

Promising new combination of drugs identified to treat juvenile myelomonocytic leukemia

Indiana University School of Medicine researchers have identified a promising new combination of drugs to treat juvenile myelomonocytic leukemia (JMML), a rare form of blood cancer that affects children.

New discoveries made regarding autism onset in mouse models

Although autism is a common neurodevelopmental disorder, the multiple factors behind its onset are still not fully understood.

B lymphocytes play a pivotal role in promoting an emergent response during infection

An SOS signals a call for immediate action during an emergency to request a need for protection. The immune system, a network of defense mechanisms, enhances protection to recover the body's internal stability.

Characterization of Ikaros zinc finger protein 1 mutations in acute myeloid leukemia

Researchers evaluated the clinical and genetic characteristics of acute myeloid leukemia (AML) patients with a mutant Ikaros zinc finger protein 1 (IKZF1).

Acquired mutations in 'Guardian of the Genome' accelerate the development of atherosclerosis

A team at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), working in collaboration with institutes in the USA, has demonstrated that acquired mutations in the gene encoding the protein p53 contribute to the development of atherosclerotic cardiovascular disease.

An epigenetic modification improves the defense against infections, research shows

During infections, the hematopoietic system switches from normal to emergency mode. This improves the defense against the pathogens.

Evaluating cell-free DNA-based blood tests for early detection of multiple cancers

Researchers assessed several approaches for a circulating cell-free deoxyribonucleic acid (cfDNA)-based multi-cancer early detection (MCED) test. Defining the clinical limit of detection (LOD) based on circulating tumor allele fraction (cTAF) enables the comparison of different approaches.

Study uncovers how the TAZ protein protects hematopoietic stem cells from aging

A well-functioning immune system is essential for protection against infections. However, with increasing age, the functioning of the immune system diminishes, which is also due to age-related damage in hematopoietic (blood) stem cells.

Plasma proteome signature predictive of occurrence of persistent symptoms following SARS-CoV-2 infection

In a new study, researchers performed a proteomic multiple-reaction monitoring analysis of 91 pre-selected proteins using the plasma samples of 156 healthcare workers (HCW) in the United Kingdom (UK).

Live imaging and cellular barcoding reveal how new stem cells are vetted for quality

Using live imaging and cellular barcoding, researchers in the Stem Cell Program at Boston Children's Hospital have glimpsed how new stem cells -; in this case, blood stem cells -; are vetted for quality soon after they're born.

The impact of sleep fragmentation on the clonal diversity of immune cells and the genetic aging of the hematopoietic system

A new study shows that sleep does much more, regulating the normal production of blood cells. This finding underlines how essential a healthy sleep routine is for a normal life.

A good night's sleep promotes immunity

In a recent study published in the Journal of Experimental Medicine, researchers in the United States used mice models to understand how sleep fragmentation affects immunological responses and the epigenetic modifications of hematopoietic stem and progenitor cells (HSPCs). They also conducted a sleep restriction trial in humans to determine HPSC programming and hematopoiesis.

How does origin impact antiviral immune response?

A new study observed differential antiviral responses in Indian and European individuals.

Researchers identify a potential new therapeutic approach to fight angioimmunoblastic T-cell lymphoma

A type of blood cell cancer called angioimmunoblastic T-cell lymphoma (AITL) can develop as mutations accumulate with age in the stem cells from which the T cells in the blood develop.

KAUST bioscientists develop new method to study the bone marrow microenvironment in greater detail

Deep molecular analysis of the bone marrow microenvironment reveals that the cells regulating blood stem cell maintenance are more diverse than expected and have features likely to be conserved between species.

Mitochondrial DNA mutations are associated with an increased risk of atherosclerosis

Mitochondria are organelles found within most cells, best known for generating the chemical energy required to power cellular functions.

IRB Barcelona researchers discover genetic drivers of clonal hematopoiesis

Clonal hematopoiesis is a biological process in which a blood stem cell (the population that gives rise to a variety of blood cell types) acquires an advantageous mutation and outgrows neighboring cells.

Scientists discover a surprising link between mitochondria, inflammation and DNMT3A and TET2 genes

Mitochondria are known as cells' powerhouses, but mounting evidence suggests they also play a role in inflammation. Scientists from the Salk Institute and UC San Diego published new findings in Immunity on July 26, 2022, where they examined human blood cells and discovered a surprising link between mitochondria, inflammation and DNMT3A and TET2-; two genes that normally help regulate blood cell growth but, when mutated, are associated with an increased risk of atherosclerosis.
