Molecular insights into myelomeningocele via proteomic analysis of amniotic fluid.

Despite numerous studies on fetal therapy for myelomeningoceles (MMC), the pathophysiology of this malformation remains poorly understood. This study aimed to analyze the biochemical profile and proteome of amniotic fluid (AF) supernatants from MMC fetuses to explore the prenatal pathophysiology. Biochemical analysis of 61 AF samples from MMC fetuses was compared with 45 healthy fetuses' samples.

GPATCH11 variants cause mis-splicing and early-onset retinal dystrophy with neurological impairment.

Here we conduct a study involving 12 individuals with retinal dystrophy, neurological impairment, and skeletal abnormalities, with special focus on GPATCH11, a lesser-known G-patch domain-containing protein, regulator of RNA metabolism. To elucidate its role, we study fibroblasts from unaffected individuals and patients carrying the recurring c.328+1 G > T mutation, which specifically removes the main part of the G-patch domain while preserving the other domains.

Extracellular vesicles from microglial cells activated by abnormal heparan sulfate oligosaccharides from Sanfilippo patients impair neuronal dendritic arborization.

Background: In mucopolysaccharidosis type III (MPS III, also known as Sanfilippo syndrome), a pediatric neurodegenerative disorder, accumulation of abnormal glycosaminoglycans (GAGs) induces severe neuroinflammation by triggering the microglial pro-inflammatory cytokines production via a TLR4-dependent pathway. But the extent of the microglia contribution to the MPS III neuropathology remains unclear. Extracellular vesicles (EVs) mediate intercellular communication and are known to participate in the pathogenesis of adult neurodegenerative diseases.

PP1 phosphatase controls both daughter cell formation and amylopectin levels in Toxoplasma gondii.

Virulence of apicomplexan parasites is based on their ability to divide rapidly to produce significant biomass. The regulation of their cell cycle is therefore key to their pathogenesis. Phosphorylation is a crucial posttranslational modification that regulates many aspects of the eukaryotic cell cycle.

Flavan-3-ols and Vascular Health: Clinical Evidence and Mechanisms of Action.

Cardiovascular diseases (CVDs) are one of the main causes of mortality and morbidity worldwide. A healthy diet rich in plant-derived compounds such as (poly)phenols appears to have a key role in improving cardiovascular health. Flavan-3-ols represent a subclass of (poly)phenols of great interest for their possible health benefits.
