Environmental stress induces an arrest of the cell cycle. Thus, release from this arrest is essential for cell survival. The cell-cycle-arrest occurs via the down regulation of the cyclins that drive the main cyclin dependent kinase, CDK1/Cdc28.

Article Synopsis
  • The trafficking of cell-surface proteins from endosomes to the plasma membrane is crucial for regulating synaptic function, with two main pathways identified: SNX27-Retromer-WASH and SNX17-Retriever-CCC-WASH.
  • This study reveals that the SNX17 pathway is essential for maintaining excitatory synapses and supporting structural plasticity in neurons, particularly during chemical long-term potentiation (cLTP).
  • SNX17's function at synapses is influenced by NMDAR activation and CaMKII signaling, highlighting its role in regulating β1-integrin levels and providing critical insight into synaptic maintenance and plasticity mechanisms.

Many neurodegenerative diseases, including Huntington's disease (HD) and Alzheimer's disease (AD), occur due to an accumulation of aggregation-prone proteins, which results in neuronal death. Studies in animal and cell models show that reducing the levels of these proteins mitigates disease phenotypes. We previously reported a small molecule, NCT-504, which reduces cellular levels of mutant huntingtin (mHTT) in patient fibroblasts as well as mouse striatal and cortical neurons from an Hdh mutant mouse.

Relying on anthropomorphism research, Illness Personification Theory (ILL-PERF) posits that individuals living with a chronic illness ascribe human-like characteristics to their illness. Herein we examine the personification of chronic pain using a new measure: the Ben-Gurion University Illness Personification Scale (BGU-IPS). Three samples of chronic pain patients (Sample 1 and 2 are distinct samples sharing similar characteristics, collected in the context of a cross-sectional design, Ns = 259, 263; Sample 3: a 2-waves longitudinal, N =163) completed the 12-item BGU-IPS, and measures of pain and related factors.
