Background: Huntington disease (HD), a neurodegenerative autosomal dominant disorder, is characterized by involuntary choreatic movements with cognitive and behavioral disturbances. Up to now, no therapeutic strategies are available to completely ameliorate the progression of HD. has various pharmacologic effects such as antioxidant and anti-inflammatory activities.

Since their approval, tyrosine kinase inhibitors (TKIs) have been widely used in antitumor therapy for chronic myeloblastic leukemia. Despite being approved by the FDA in 2001 to treat a rare cancer called chronic myeloid leukemia (CML), imatinib and other TKIs remain subjects of research for several reasons, such as their long-term effects, resistance, or molecular mechanisms. This study uses Raman and fluorescence imaging to investigate the cytotoxic effects of two TKIs, imatinib and dasatinib, on human aortic endothelial cells (HAECs).

Genetic control - the deliberate introduction of genetic traits to control a pest or vector population - offers a powerful tool to augment conventional mosquito control tools that have been successful in reducing malaria burden but that are compromised by a range of operational challenges. Self-sustaining genetic control strategies have shown great potential in laboratory settings, but hesitancy due to their invasive and persistent nature may delay their implementation. Here, instead, we describe a self-limiting strategy, designed to have geographically and temporally restricted effect, based on a Y chromosome-linked genome editor (YLE).

Identifying broadly reactive B precursor cells and conserved epitopes is crucial for developing a universal flu vaccine. In this study, using influenza neuraminidase (NA) mutant probes, we find that human pre-existing NA-specific memory B cells (MBCs) account for ∼0.25% of total MBCs, which are heterogeneous and dominated by class-unswitched MBCs.

Background: Adaptative desaturation in fatty acid (FA) is an emerging hallmark of cancer metabolic plasticity. Desaturases such as stearoyl-CoA desaturase (SCD) and fatty acid desaturase 2 (FADS2) have been implicated in multiple cancers, and their dominant and compensatory effects have recently been highlighted. However, how tumors initiate and sustain their self-sufficient FA desaturation to maintain phenotypic transition remains elusive.
