Extracellular vesicles (EVs) recently took centre stage as mediators of cellular crosstalk modulating the tissue microenvironment. Released by all types of neural cells, EVs may execute a broad spectrum of functions ranging from maintenance of neuronal homeostasis and regulation of neural plasticity to the spread of neurodegenerative agents. Myelinating oligodendrocytes and axons form a highly specialized functional entity that depends on intimate interactions within the oligodendrocyte-neuron niche. EVs released by oligodendrocytes are internalized by neurons in response to neuronal signals and exhibit neuroprotective properties but also may influence other cells present in the microenvironment. Here we discuss the role of EVs released by oligodendrocytes in regulating development, homeostatic maintenance and regeneration within the oligodendrocyte niche.

Summary: This study investigated the association of cell-free circulating DNA (cfDNA) and cancer-derived extracellular vesicles (EVs) in healthy human plasma. It found that only a small portion of cfDNA is associated with EVs, primarily on the outer surface. Exercise was shown to increase the levels of EVs, cfDNA, and EV-associated DNA, with the majority of DNA being located on the outer surface of circulating EVs rather than in their lumen.

Mechanisms of axonal support by oligodendrocyte-derived extracellular vesicles

Eva-Maria Kraemer-Albers, Hauke B. Werner

Summary: Extracellular vesicles (EVs) have been identified as important mediators of cell communication in the nervous system, particularly between oligodendrocytes and neurons. EVs play a crucial role in maintaining the structural integrity of axons by delivering key factors that improve axonal transport, stress resistance, and energy homeostasis. Dysfunction in glial support and the transfer of EVs can lead to loss of axonal integrity observed in myelin-related disorders, neurodegenerative diseases, and ageing. Understanding the mechanisms of EV-mediated interactions is essential for therapeutic applications.

Summary: Extracellular vesicles (EVs) released by cells carry specific biomolecules that can be used as liquid-biopsy markers for diagnosing brain diseases. This study evaluated a flow cytometry platform called EV Neuro assay for identifying and characterizing CNS-derived EVs and disease-specific markers in complex samples. The study compared different sample materials and EV isolation methods and found distinct EV profiles in glioblastoma cell lines and human astrocytes. The intensity of EV markers increased with higher EV input. Analysis of blood samples from patients with brain diseases and healthy controls showed varying EV marker intensities between individuals. Data normalization improved the identification of disease-specific markers. The EV Neuro assay proved useful for profiling EVs in complex samples. However, larger sample cohorts and higher effect sizes are needed for more reliable results in biomarker studies. Nonetheless, this study confirmed the potential of the EV Neuro assay for discovering disease-associated EV markers and monitoring circulating EV profiles in CNS diseases.

Neural correlates of social interaction anxiety and their relation to emotional intelligence: A resting-state fMRI study

Song Xue, Feng Kong, Yiying Song, Jia Liu

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Alamandine injection in the periaqueductal gray and rostral ventromedial medulla attenuates allodynia induced by sciatic nerve ligation in rats

Zahra Gholami, Ava Soltani Hekmat, Ali Abbasi, Kazem Javanmardi

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Evaluation of the separate and combined effects of anodal tDCS over the M1 and F3 regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain

Ahmad Alipour, Roghayeh Mohammadi

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
