What are the nerve-dependent developmental and regenerative processes?
10 answers
Nerve-dependent developmental and regenerative processes are critical for the anatomical and functional restoration of parts removed from or damaged in an organism. These processes, observed across a variety of species and tissues, from zebrafish to humans, highlight the essential role nerves play in supporting tissue repair and regeneration. The phenomenon of nerve dependence in regeneration has been extensively studied, particularly in the context of amphibian limb regeneration, where nerves influence the regenerative growth under certain conditions, such as in the avascular early blastema stage. In the peripheral nervous system, injury triggers a coordinated lesion-induced gene expression program, indicating the activation of a regenerative growth mode. This response includes the recapitulation of developmental processes and the activation of regeneration-specific genes, suggesting that regeneration partially mirrors development but also involves unique, injury-specific molecular reactions. The molecular basis of nerve influence in regeneration includes the release of factors like transferrin and fibroblast growth factors (FGFs), which promote growth and are critical during the early, nerve-dependent phase of limb regeneration. Research has also identified specific genes, such as Dlx-3 in axolotls, that correlate with the transition from nerve-dependent to nerve-independent phases of limb regeneration, highlighting the complex interplay between nerves, gene expression, and tissue regeneration. Moreover, the presence of nerve axons is required for the division of blastemal cells, the progenitors of regenerate tissues, during the initial stages of limb regeneration. In contrast to other tissues, the nervous system's regeneration does not involve division of mature neurons but rather the replacement and elongation of damaged parts, often the axon, supported by division in ancillary cells like glia and Schwann cells. Studies using microarray analysis and cDNA sequencing have further elucidated the transcriptional programs underlying nerve-dependent limb regeneration, revealing similarities and differences between innervated and denervated limbs in terms of gene expression related to wound healing and cell proliferation. Finally, the process of regeneration, while sharing similarities with embryonic development, is distinct in its direct development from and relation to adult tissues, emphasizing the unique nature of regenerative processes and their dependence on adult physiological conditions.
What is amyotrophic lateral sclerosis?
5 answers
Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease or Lou Gehrig's disease, is a progressive neurodegenerative disorder affecting the motor system. It leads to the degeneration of both upper and lower motor neurons in the brain and spinal cord, resulting in muscle weakness, atrophy, spasticity, and eventually paralysis. The exact cause of sporadic ALS is unknown, but familial cases have been linked to mutations in over 30 genes. Pathological processes central to ALS include protein instability, RNA processing perturbations, and disruptions in homeostasis, leading to protein aggregation, mitochondrial disturbances, and axonal transport issues. Despite no identified risk factors or family history in most cases, treatments aim to manage symptoms and improve quality of life.

ALS mimics can lead to diagnostic errors and delays in starting potentially curative treatments, emphasizing the importance of excluding similar conditions. For instance, a case study reported a neurofibroma of the dorsal spinal cord mimicking ALS, showcasing the diagnostic challenges posed by ALS mimic syndromes. Understanding the spectrum of clinical presentations of ALS and its mimics is crucial due to the lack of specific diagnostic biomarkers for ALS, highlighting the necessity for accurate identification of these disorders to avoid misdiagnosis and initiate effective treatment where available.
What is the role of the autonomic nervous system in regulating heart rate and blood pressure?
5 answers
The autonomic nervous system (ANS) plays a crucial role in regulating heart rate and blood pressure. The ANS consists of the sympathetic and parasympathetic systems, which exert antagonistic effects on these vital functions. The sympathetic system, associated with the "fight-or-flight" response, increases heart rate and blood pressure, while the parasympathetic system, related to "rest-and-digest" circumstances, lowers heart rate and blood pressure. Dysfunction in the ANS can lead to disorders affecting heart rate and blood pressure. Studies have focused on understanding autonomic dysfunction in various pathophysiological states like hypertension, heart failure, and diabetes, where ANS alterations contribute to autonomic neuropathy. Overall, the ANS, through its sympathetic and parasympathetic branches, finely tunes heart rate and blood pressure to maintain physiological balance and respond to internal and external stimuli.
Senolytics: A Novel Strategy for Neuroprotection in ALS?
4 answers
Senolytics, a novel therapeutic strategy, show promise for neuroprotection in Amyotrophic Lateral Sclerosis (ALS) by targeting senescent glial cells involved in motor neuron degeneration. Neuroprotection in ALS aims to slow or halt neurodegenerative processes, focusing on oxidative stress, mitochondrial dysfunction, excitotoxicity, inflammation, and protein aggregation. Studies have explored neuroprotective approaches like melatonin treatment, which demonstrated efficacy in reducing cell death and disease progression in ALS preclinical models. Additionally, preserving lower motor neurons (LMNs) is crucial in ALS, leading to the investigation of strategies such as modulating neurotransmitter inputs, neurotrophic support, and addressing inflammation and abnormal energy metabolism for neuroprotection. These combined efforts highlight the potential of senolytics and other neuroprotective strategies in ALS treatment.
What are the current protocols for scanning electron microscopy of spinal roots?
9 answers
The current protocols for scanning electron microscopy (SEM) of spinal roots involve several critical steps tailored to preserve the ultrastructure of the nerve tissues while enabling detailed imaging. Initially, specimens, such as human dorsal nerve roots, are fixed using buffered osmium tetroxide and stained with phosphotungstic acid during dehydration before embedding in a resin like Araldite for sectioning and examination under an electron microscope. This fixation and staining protocol is crucial for maintaining the integrity of the nerve tissues. For samples like young dogs' nerve roots, buffered aldehydes are used for perfusion, followed by MICROFIL injection to prevent vascular collapse. The dura-arachnoid is exposed, and nerve exits and rootlets are dissected free for SEM imaging, after which they are embedded in Epon 812 for further light and transmission electron microscopy. This method highlights the importance of preserving vascular and nerve root structures during preparation. In studies focusing on the surface morphology of normal and regenerated nerve roots, correlated scanning and transmission electron microscopic methods are employed. The nerve roots are processed to visualize surface structures and cells, with particular attention to the regeneration process, demonstrating alterations in surface structure due to collagen growth. For delicate biological samples, including nerve tissues, protocols recommend using Critical Point Drying (CPD) to avoid cell collapse and distortion, ensuring high-quality SEM images. This technique is essential for preserving the natural morphology of the samples. Moreover, the preparation of specimens for SEM can also involve innovative methods like the one introduced for revealing intracellular structures, where root tips are fixed, frozen, fractured, and then treated with dilute solutions of aldehyde and osmium tetroxide. This method, although not directly applied to spinal roots in the provided contexts, suggests a potential approach for detailed SEM analysis of nerve tissues by removing excess cell-matrix and allowing a deep view into the cell interior. In summary, the protocols for SEM of spinal roots encompass a range of techniques from fixation, staining, and embedding to innovative methods for sample preparation, all aimed at preserving the ultrastructure for detailed imaging.
Is the N1 sign (Nigrosome 1) systematically visualized at 7T and what about 3T ?
