    Lack of the Human Choline Transporter-Like Protein SLC44A2 Causes Hearing Impairment and a Rare Red Blood Phenotype

    By investigating alloantibodies to a high-prevalence antigen of unknown specificity, found in patients with a rare blood type, the authors showed that SLC44A2 was also expressed in red blood cells and carried a new blood group system.

    The Immunomodulatory Molecule TIGIT Is Expressed by Chronic Lymphocytic Leukemia Cells and Contributes to Anergy

    Scientists studied the expression of T-cell immunoreceptor with Ig and ITIM domains (TIGIT) and CD226 in a cohort of 115 chronic lymphocytic leukemia patients and reported the expression of TIGIT and CD226 by leukemic cells.

    Asciminib vs Bosutinib in Chronic-Phase Chronic Myeloid Leukemia Previously Treated with at Least Two Tyrosine Kinase Inhibitors: Longer-Term Follow-Up of ASCEMBL

    To further assess the long-term benefits and risks of asciminib compared with those of bosutinib in patients with chronic myeloid leukemia in the chronic phase after ≥2 prior tyrosine kinase inhibitors, scientists reported efficacy and safety results in ASCEMBL after a median follow-up of 2.3 years.

    A Proactive Approach to Prevent Hematopoietic Exhaustion During Cancer Chemotherapy in Older Patients: Temporary Cell-Cycle Arrest

    Contrary to the classical path using growth factors to activate tissue regeneration, a novel strategy is emerging to prevent chemotherapy toxicity that involves the temporary cell-cycle arrest of normal cells, such as hematopoietic or epithelial precursors. This proactive approach may allow the sparing of the stem cell reserve of these tissues.

    FDA Eases Rules Again for Gay Men Seeking to Donate Blood

    The FDA announced draft guidelines that would do away with the current three-month abstinence requirement for donations from men who have sex with men. Potential donors would be screened with a questionnaire that evaluates their risks for HIV based on factors like sexual behavior and recent partners.
