Article Synopsis
- The study evaluated the effectiveness of therapeutic drug monitoring for pediatric inflammatory bowel disease (IBD) patients using two pharmacokinetic models to analyze adalimumab levels post-induction.
- A retrospective review identified that most patients with Crohn disease required monitoring, and the de Klaver model showed less bias in predicting adalimumab concentrations compared to the Ternant model.
- Findings revealed that nearly 50% of patients needed dose adjustments during maintenance therapy to reach effective drug levels and maintain remission.
Palmitic acid (PA) is significantly increased in the hypothalamus of mice, when fed chronically with a high-fat diet (HFD). PA impairs insulin signaling in hypothalamic neurons, by a mechanism dependent on autophagy, a process of lysosomal-mediated degradation of cytoplasmic material. In addition, previous work shows a crosstalk between autophagy and the primary cilium (hereafter cilium), an antenna-like structure on the cell surface that acts as a signaling platform for the cell.

- In 2008, guidelines were established for researching autophagy, which has since gained significant interest and new technologies, necessitating regular updates to monitoring methods across various organisms.
- The new guidelines emphasize selecting appropriate techniques to evaluate autophagy while noting that no single method suits all situations; thus, a combination of methods is encouraged.
- The document highlights that key proteins involved in autophagy also impact other cellular processes, suggesting genetic studies should focus on multiple autophagy-related genes to fully understand these pathways.
High-fat diet (HFD)-induced obesity is associated with increased cancer risk. Long-term feeding with HFD increases the concentration of the saturated fatty acid palmitic acid (PA) in the hypothalamus. We previously showed that, in hypothalamic neuronal cells, exposure to PA inhibits the autophagic flux, which is the whole autophagic process from the synthesis of the autophagosomes, up to their lysosomal fusion and degradation.

Cilia control different cellular functions ranging from motility (for motile cilia) to signal transduction pathways (for primary cilia). A variety of signaling pathways are coordinated by this organelle during development, cell migration and cell differentiation.
