Targeting the CD74 signaling axis suppresses inflammation and rescues defective hematopoiesis in -familial platelet disorder.

Familial platelet disorder (FPD) is associated with germline mutations, establishing a preleukemic state and increasing the risk of developing leukemia. Currently, there are no intervention strategies to prevent leukemia progression. Single-cell RNA sequencing ( = 10) combined with functional analysis of samples from patients with -FPD ( > 75) revealed that FPD hematopoietic stem and progenitor cells (HSPCs) displayed increased myeloid differentiation and suppressed megakaryopoiesis because of increased activation of prosurvival and inflammatory pathways.

A Review of the Consequences of Gut Microbiota in Neurodegenerative Disorders and Aging.

Age-associated alterations in the brain lead to cognitive deterioration and neurodegenerative disorders (NDDs). This review with a particular focus on Alzheimer's disease (AD), emphasizes the burgeoning significance of the gut microbiota (GMB) in neuroinflammation and its impact on the gut-brain axis (GBA), a communication conduit between the gut and the central nervous system (CNS). Changes in the gut microbiome, including diminished microbial diversity and the prevalence of pro-inflammatory bacteria, are associated with AD pathogenesis.

Prevalence of allergic rhinitis, atopic dermatitis, and wheezing at 15 and 22 years of age: the 1993 Pelotas (Brazil) Birth Cohort Study.

Objectives: To estimate the prevalence of allergic rhinitis (AR), atopic dermatitis (AD), and wheezing, and to describe their patterns of co-occurrence according to different characteristics in adolescence and early adulthood.

Methods: Cross-sectional analyses from the 15-year and 22-year follow-ups of the 1993 Pelotas (Brazil) Birth Cohort. The outcomes were assessed based on self-reported data, and the patterns of co-occurrence were determined using cluster analysis.

Cardiovascular Effects of a Glycosylated Flavonoids-Rich Leaf Extract from Brazilian : A Potential Health Bio-Input.

: Bioactivity assessments of plant-derived products can benefit human and animal health, especially in regions with vast plant diversity. This study focused on chemical and cardiovascular analyses of A. St.

Ascorbic acid regulates and toxicogenetic effects of hydroxyurea on eukaryotic cells.

Hydroxyurea (HU) exerts unique and diverse biological effects as an anti-leukemic agent, irradiation sensitizer, and HbS inducer in patients with sickle cell anemia. Herein, we assessed the potential toxicogenic and/or oxidant effects of hydroxyurea associated with ascorbic acid by examinations in and human cancer cells and systemically on mice tissues. Growing roots and HCT-116 colorectal tumor cells were examined after HU and HU plus ascorbic acid exposure.
