Summary: The correct wiring of a neural network requires neurons to integrate cues from their extracellular environment, and biologically inspired micro- and nanostructured substrates can regulate axonal outgrowth. Graphene, as a conductive neural interface, has the potential to enhance cell adhesion and neural sprouting. This study found that nanoscale protruding features influenced neuronal growth and branching, and the integrin-mediated contact adhesion points and plasma membrane curvature processes played a crucial role in neurons-to-graphene coupling.

Summary: Blocking the energy sensor mTORC1 in POMC neurons can mimic a cellular negative energy state, leading to hyperphagia. The functional specificity of the GABA and glutamate subpopulations in POMC neurons relies on the activity of mTORC1.

Summary: In C. elegans, the loss of the Kinesin-13 family microtubule-depolymerizing enzyme KLP-7 leads to ectopic extension of axon-like processes from the PLM cell body. This phenomenon depends on both KLP-7 and the minus-end binding protein PTRN-1, revealing the mechanism by which Wnt signaling establishes microtubule polarity in neurons through Kinesin-13.

Summary: Insulin receptor signaling plays a role in growth. Patients with hyperinsulinemia and impaired insulin receptor function show impaired growth and lower bone mineral density, while elevated insulin receptor signaling leads to accelerated growth and higher bone mineral density. This suggests that insulin receptor influences growth through direct metabolic effects in bone and indirect effects via the growth hormone-IGF-1 axis.

Summary: The tumour microenvironment, particularly the presence of neurons, plays a crucial role in promoting malignancy across various types of cancer. A recent study on glioblastoma has revealed bidirectional signalling between tumours and neurons, resulting in a vicious cycle of proliferation and brain hyperactivity. This phenomenon is driven by specific neuronal subpopulations and tumour subtypes that remain incompletely understood. Further research has identified callosal projection neurons located in the hemisphere contralateral to primary GBM tumours as key promoters of tumour progression and infiltration. Additionally, the activity-dependent infiltrating population, enriched for axon guidance genes, has been found to be regulated by the SEMA4F gene, which promotes tumourigenesis and bidirectional signalling with neurons, leading to brain network hyperactivity.

Summary: This study reveals the important role of neuronal TRPV1 in regulating bone defect repair. Activation of TRPV1 triggers the production of CGRP, leading to accelerated bone healing. In contrast, knockdown of TRPV1 reduces CGRP expression and impairs bone formation and osteogenic capability. Neuronal TRPV1 enhances osteoblast physiology through the Hippo signaling pathway.

Summary: The establishment and maintenance of neuronal polarity are crucial for neural development and function, and abnormal polarity can lead to neurodevelopmental disorders. Recent studies have made significant progress in understanding the molecular mechanisms of neuronal polarity through positive and negative feedback signals and actin waves. These mechanisms drive the transport and aggregation of key molecules, regulate the interactions of actin filaments and microtubules, promote axon specialization and growth, and inhibit the formation of multiple axons. This review focuses on recent findings regarding neuronal polarity in two classical models, primary hippocampal/cortical neurons in vitro and cortical pyramidal neurons in vivo, and discusses the current understanding of neuronal polarity.

Summary: Truncation of IRF2BPL leads to severe childhood-onset neurodegenerative disorders. Through studies in Drosophila and zebrafish, it has been found that IRF2BPL can repress Wnt transcription, and dysregulation of Wnt signaling is associated with neural dysfunction and axonal loss.

Summary: Prostate cancer is initially androgen-dependent and the Rac signaling pathway plays a crucial role in cancer progression. Loss of HACE1 leads to hyperactive Rac signaling, while Rac inhibition can attenuate the growth and survival of prostate cancer cells. Rac is critical in prostate cancers expressing the androgen receptor.

Summary: The study identified ADGRL1 as a potential receptor for TAFA2, which directly binds to TAFA2 through its lectin-like domain. Overexpression of ADGRL1 induced apoptosis, but not ADGRL1 Delta Lec, and this apoptosis could be suppressed by recombinant TAFA2. These results suggest TAFA2 and its receptor ADGRL1 as potential therapeutic targets for neurological disorders.

Summary: This review discusses the interactions of protease activated receptors (PARs) with their own family members as well as with other types of receptors. The authors point out that the cross-talk between receptors and signaling pathways is a novel mechanism providing diversity to receptor function and playing important roles in physiology and disease.

Summary: Neuronal-epithelial cross-talk drives acinar specification through NRG1-ERBB3-mTORC2 signaling. NRG1-ERBB3 regulates the cellular programs of lineage progression, secretion, and polarization through the mTORC2 signaling pathway. This mechanism plays a crucial role in the formation of functional acini.

Summary: During subarachnoid haemorrhage, the release of extracellular haemoglobin (Hb) causes oxidative damage and cell death in surrounding tissues. This study shows that haptoglobin can protect surviving neurons by scavenging free Hb and preventing cellular damage and deficits in synaptic function. The findings support the potential use of haptoglobin as a therapy for subarachnoid haemorrhage.

Summary: This study identifies a reactive astrocyte sub-state called interferon-responsive reactive astrocytes (IRRAs) and characterizes their proteomic changes. The researchers found that IRRAs have distinct features from neurotoxic reactive astrocytes (NRAs), including unique protein expressions. This study lays the foundation for future investigations of the functional roles of IRRAs in neurodegenerative disorders.

Summary: The study found that different UPR markers did not change in the late stages of any human tauopathies investigated, but UPR signatures were often observed in non-demented controls. The results suggest an activation of UPR markers in the aged brain across all investigated cohorts, supporting the emerging evidence that misfolded cytosolic tau accumulation does not drive disease-associated UPR activation.
