Summary: Excitatory projection neurons and inhibitory interneurons are the primary actors in the neural activity of the cerebral cortex, and an imbalance in excitatory-inhibitory neural networks can lead to neuropsychiatric diseases. Gamma-aminobutyric acid (GABA)ergic interneurons mediate inhibition and the embryonic medial ganglionic eminence (MGE) is a source of GABAergic interneurons. Transplanted MGE cells can migrate, differentiate into different subtypes of GABAergic interneurons, integrate into host neural circuits, enhance synaptic inhibition, and have potential application in diseases associated with interneuron disorders.

Summary: Hypoparathyroidism is a disorder characterized by low calcium levels, high phosphorus levels, and insufficient or absent secretion of PTH. Hormone replacement therapy with calcium and vitamin D is common, but may not always be effective long-term. Glandular autotransplantation is considered the most effective treatment, while allograft has limited success due to tissue rejection and side effects from systemic immunosuppression. Research is ongoing to discover alternative graft therapies with optimal results and minimal side effects.

Summary: The spinal cord connects the brain to the peripheral nervous system and peripheral tissues through neurons and various types of glial cells. Neurons in the spinal cord process sensory input and control movement. Neurodegenerative disorders and traumatic injuries affecting the spinal cord result in motor deficits and loss of sensory inputs.

Summary: Triterpenoid saponins enhance the cytotoxicity of saporin-based immunotoxins by promoting the endolysosomal escape of the toxin to the cytosol. Various pharmacological inhibitors of different endocytic processes were used as probes to investigate the involvement of saponins in this process, with results suggesting a potential role of clathrin-mediated endocytosis and endosomal acidification in the internalization of saponins and the escape of toxins from the endolysosomal compartment to the cytosol. The correlation with the effects of these inhibitors on cytotoxicity augmentation provides additional evidence for the importance of endolysosomal escape in driving enhancement of cytotoxicity.

Summary: Impairment of inhibitory interneurons is a key feature of neurological disorders like epilepsy. Current treatment options involve drugs or deep brain stimulation, but a more effective strategy would be to add new inhibitory interneurons to pathological circuits. One promising approach is using MGE progenitor cells as a source of interneurons for transplantation, which has shown success in preclinical models of epilepsy. This article discusses the evolution of this therapy, particularly its adaptation for xenotransplantation in larger mammals.

Summary: The study found that specific types of interneurons in the human neocortex, such as rosehip cells and layer 2-3 innervating cells, exhibit larger tonic GABA(A) receptor currents compared to other interneuron types, potentially allowing for selective modulation of cortical circuitry. Patient parameters like age, seizures, cancer type, and anticonvulsant treatment were also examined for their potential influence on tonic inhibitory currents in human neurons.

Summary: This study investigated the benefits of autologous-stem cell transplantation (auto-SCT) and allogeneic-SCT (allo-SCT) in aggressive T-cell lymphoma patients. A total of 598 patients who underwent transplantation from 2010 to 2020 were analyzed retrospectively. Auto-SCT showed better overall survival (OS) than allo-SCT, but no difference in progression-free survival (PFS). In salvage therapy, auto-SCT improved long-term survival in complete remission (CR) patients, while allo-SCT had better 3-year PFS in partial remission and relapsed/refractory disease. However, more than 50% of patients died within 1 year of allo-SCT. Up-front auto-SCT as consolidation therapy demonstrated a survival benefit.

Summary: The study found that marmosets exhibit stronger neural activation and a more complex pattern of brain activation after intense stimulation compared to rats, with a wider and longer-lasting c-Fos expression. Rats showed similar patterns of c-Fos expression based on the function of different brain cortical structures, while marmosets did not exhibit clear patterns and showed a more diverse profile.

Summary: Defects in GABAergic function can lead to anxiety and depression, while therapeutic strategies involving transplantation of GABAergic interneuron progenitors from the MGE into the hippocampus have shown to reverse symptomatology in various rodent models. The LPA(1) receptor is crucial for hippocampal function, and deficits in its signaling may underlie neuropsychiatric conditions. Studies in maLPA(1)-null mice demonstrated that transplanted interneuron precursors can restore the hippocampal environment, decrease anxiety-like behaviors, and normalize coping responses without affecting motor activity.

Summary: The endocannabinoid system plays a role in regulating synaptic plasticity in the hippocampus during memory formation. The mechanisms underlying this regulation are not well understood. In this study, the authors investigated the effects of AM404, an inhibitor of anandamide transport and metabolism, on aversive memory consolidation. They found that AM404 disrupted memory consolidation and retrieval, and abolished Long-Term Potentiation induction. The effects of AM404 were reversed by metyrapone, suggesting an interaction between glucocorticoids and endocannabinoids in memory consolidation. CB1 receptors mediated the amnestic effect caused by increased anandamide levels, while TRPV1 receptors did not. The results also suggest an interesting interaction between the endocannabinoid and cholinergic systems.

Summary: Prenatal exposure to valproic acid (VPA) leads to autism spectrum disorder (ASD), but resveratrol (RSV) can prevent these impairments. This study found that prenatal VPA exposure reduced synaptic inhibition in the somatosensory area, resulting in behavioral and electroencephalogram changes. However, RSV prevented these synaptic inhibition alterations and improved behavioral and electroencephalogram abnormalities.

Summary: The study shows that HMG20A is predominantly expressed in hypothalamic astrocytes, with its upregulation in obesity and glucose intolerant conditions playing a key role in maintaining neuronal network and glucose homeostasis. Depletion of HMG20A in astrocytes leads to impaired function, which can be reversed by ORY1001 treatment.

Summary: Recent research on preventing post-traumatic epilepsy has made significant advancements in understanding its physiopathology, including the search for biomarkers, development of new animal models, and investigation of new drugs. However, limiting the search for biomarkers and new drugs to only a few TBI models may hinder the overall understanding of this relevant yet unpreventable medical condition.
