A clinical trial showed that an antibody blocking Nogo-A protein improves motor function in patients with incomplete spinal cord injuries. The treatment led to significant improvements in voluntary muscle activation and everyday life functional independence. Further studies are needed to confirm the findings.
A USC-led study found that neurogenesis in adults supports verbal learning and memory, enabling people to have conversations. The discovery could lead to new approaches to restore cognitive function in patients with epilepsy and other conditions.
A recent study has identified Kif23 as a key regulator of embryonic brain development, highlighting its potential link to microcephaly. The research found that Kif23 is essential for neural progenitor cell proliferation and differentiation, with deficiency leading to decreased cell growth and increased apoptosis.
A recent study found that oleacein increases BDNF expression in human neuronal cells and reduces depressive behavior in mouse models. Gene expression analysis reveals the activation of cell cycle and neurogenesis processes, as well as a decrease in inflammatory response.
The study reveals that spontaneous waves of neurotransmitter glutamate facilitate dendrite pruning, while a unique protection/punishment machinery strengthens certain connections and eliminates others. Proper pruning is critical for neural development, with insufficient or excessive connections linked to neurophysiological disorders.
A new study in a mouse model of Alzheimer's disease examines the effects of environmental enrichment on AD symptom progression and pathology. The researchers found that living in an enriched environment improved several measures of metabolism and reduced individual behaviors, which became more similar and rigid as the disease progressed.
The study reveals that non-coding regions near sloppy-paired genes are essential for temporal transcription factor expression and that Notch-signaling regulates the transition to subsequent TTFs. This mechanism couples temporal patterning with neuron generation, providing insights into brain diversity.
