Newly identified proteins that seem to act as diffusible attractants for circumferentially growing axons in the vertebrate embryonic spinal cord are related to a protein that directs circumferential axon growth in the nematode.

Hsa_circ_0001304 promotes vascular neointimal hyperplasia accompanied by autophagy activation.

Aberrant autophagy in vascular smooth muscle cells (VSMCs) is associated with the progression of vascular remodeling diseases caused by neointimal hyperplasia. Platelet-derived growth factor-BB (PDGF-BB)-induced vascular remodeling is accompanied by autophagy activation, however, the involvement of circular RNAs (circRNAs) remains unclear. Here, we show the role of PDGF-BB-regulated hsa_circ_0001304 (circ-1304) in neointimal hyperplasia and its potential involvement in VSMC autophagy, while also elucidating the potential mechanisms.

Neuromuscular diseases usually manifest as abnormalities involving motor neurons, neuromuscular junctions, and skeletal muscle (SkM) in postnatal stage. Present in vitro models of neuromuscular interactions require a long time and lack neuroglia involvement. Our study aimed to construct rodent bioengineered spinal cord neural network-skeletal muscle (NN-SkM) assembloids to elucidate the interactions between spinal cord neural stem cells (SC-NSCs) and SkM cells and their biological effects on the development and maturation of postnatal spinal cord motor neural circuits.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

The underlying pathophysiology of tics in Tourette syndrome is a topic of major scientific interest. To date, there is an absence of consensus among researchers regarding the precise anatomic location responsible for tics. The goal of this article is to review the current understanding of these brain circuits and data supporting specific anatomic regions.

Self-renewal capacity and potential to differentiate into almost any cell type of the human body makes pluripotent stem cells a valuable starting material for manufacturing of clinical grade cell therapies. Neurodegenerative diseases are characterized by gradual loss of structure or function of neurons, often leading to neuronal death. This results in gradual decline of cognitive, motor, and physiological functions due to the degeneration of the central nervous systems.
