Epigenetic abnormalities in hematopoietic cells during fetal development cause idiopathic autism

An international research group led by Professor Toru Takumi (Senior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research) and Researcher Chia-wen Lin at Kobe University Graduate School of Medicine has shown that idiopathic autism is caused by epigenetic abnormalities in hematopoietic cells during fetal development, which results in immune dysregulation in the brain and gut.

World Trade Center responders have increased levels of mutations that escalate blood cancer risk

Scientists from Vanderbilt-Ingram Cancer Center (VICC) collaborated with researchers from New York to determine that 9/11 first responders to the World Trade Center have increased levels of mutations that escalate their risk for blood cancers or cardiovascular disease, according to a study published March 7 in Nature Medicine.

Study investigates what causes blood malignancies linked to gene therapy for sickle cell disease

Gene therapy trials for sickle cell disease have been showing great promise, even offering hope of a cure. But in early 2021, the trials ground to a halt after reports of blood malignancies in two people in a trial sponsored by bluebird bio.

Donor cells with clonal hematopoiesis may improve bone marrow transplant outcomes

Clonal hematopoiesis, a condition in which mutations associated with blood cancers are found in the blood of healthy people, is common with aging.

Exposure to smoking and mutations in blood cells may lead to a rare cancer that affects immune cells

Mutations in blood cells likely caused by smoking and aging-related changes may lead to a rare type of blood cancer that affects immune cells, shows a study published today in eLife.

Novel combination therapy approach to keep leukemia at bay

In chronic leukemias, blocking the overactive kinase JAK2 by a targeted therapy approach is only mitigating the patients' symptoms, but cannot truly change the course of the disease.

Researchers investigate link between the liver’s immune system composition and NASH pathology

Our livers work hard to perform an entire range of activities: helping us digest food, maintaining body temperature and serving as an important checkpoint of the immune system for everything that we eat.

Blocking TGFβ1 could improve hematopoiesis in AML patients, indicates study

Bone marrow failure due to acute myeloid leukemia (AML) is a significant factor behind the disease's high rate of morbidity and mortality. Previous studies in mice suggest that AML cells inhibit healthy hematopoietic (blood) stem and progenitor cells (HSPC).

Toll-like receptor 2 (TLR2) detects the SARS-CoV-2 envelope protein and generates inflammatory cytokines

Researchers at St Jude Children’s Research Hospital found that toll-like receptor 2 detects the SARS-CoV-2 envelope protein-producing inflammatory cytokines.

Researchers develop an effective strategy to fight against chronic myelomonocytic leukemia

Leukemias are debilitating cancers of the hematopoietic or blood-forming cells of the bone marrow. Now, researchers at Tokyo Medical and Dental University describe an ingenious strategy against chronic myelomonocytic leukemia (CMML) wherein an antibody-drug conjugate (ADC) comprising a cytotoxic drug payload linked to an antibody that selectively targets specific cell lines effectively blocks malignant cell proliferation at source.

Study reveals reason behind high risk of leukemia in children with Down syndrome

Children with Down syndrome are 20-times more likely to develop acute lymphocytic leukemia (ALL) and 150-times more likely to develop acute myeloid leukemia (AML) compared to their typical peers.

Researchers reveal pathways that lead to the development of tissue-resident lymphocytes

Researchers from the University of Science and Technology of China) of the Chinese Academy of Science (CAS), teamed up with scientists from Aix Marseille University, discovered that hematopoietic progenitors possessed the differentiation potential to type 1 innate lymphoid cells in adult liver, and dissected the regulation mechanisms of such cell differentiation, revealing the pathways that lead to the development of tissue-resident lymphocytes.

DNMT3a plays a key role in regulating HSC responses to infections

Humans are born with tens of thousands of hematopoietic stem cells (HSCs) that collectively ensure lifelong production of blood and immune cells that protect us from infections.

Anti-inflammatory therapies may help prevent heart disease in people with age-related blood condition

Therapies that soothe inflammation could be an effective way to prevent heart disease in people with a common age-related blood condition, according to a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons.

Researchers describe new approach for hematopoietic stem cell transplant in embryos

Most people have heard of stem cells, cells from which all other cells with specialized functions are generated. Hematopoietic stem cells (HSCs) are the architects of blood cell development and are responsible for blood cell formation throughout the life of an organism.

Scientists report new insights into the development of blood cancers

Utah researchers report significant new insights into the development of blood cancers. In work published today in Blood Cancer Discovery, a journal of the American Association for Cancer Research, scientists describe an analysis of published data from more than 7,000 patients diagnosed with leukemia and other blood disorders.

Atherosclerosis can speed up the development of clonal hematopoiesis

Billions of peripheral white blood cells are produced every day by the regular divisions of hematopoietic stem cells and their descendants in the bone marrow.

New class of targeted cancer drugs may prove effective in treating common types of leukemia

A new study by researchers in Cleveland Clinic's Taussig Cancer Institute and Lerner Research Institute describes a novel class of targeted cancer drugs that may prove effective in treating certain common types of leukemia.

Clonal hematopoiesis can confer a health benefit in allogeneic transplants

Clonal hematopoiesis (CH) is a recently identified condition in which mutations associated with blood cancers are detected in the blood of some healthy, usually older, individuals who don't have cancer.
