Summary

Neurodegeneration refers to the progressive loss of neuron structure or function, which may eventually lead to cell death. Many neurodegenerative diseases, such as amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease and prion disease, are the results of neurodegenerative processes. Neurodegeneration can be found in many different levels of neuronal circuits in the brain, from molecules to systems. Since there is no known method to reverse the progressive degeneration of neurons, these diseases are considered incurable. Biomedical research has revealed many similarities between these diseases at the subcellular level, including atypical protein assembly (such as protein diseases) and induction of cell death. These similarities indicate that progress in the treatment of one neurodegenerative disease may also improve other diseases. This collection of entries aims to collect various medical research results related to neurodegeneration. We invite researchers to share their new results and ideas related to neurodegeneration.

Physiological and Molecular Differences in SMA NSCs
Neural stem cells (NSCs) in the adult nervous tissue were among the last to be identified and isolated in a living organism. While the U.S. Food and Drug Administration and the European Medicines Evaluation Agency have recently approved new drugs to treat spinal muscular atrophy 1 (SMA1) in young patients, they are mostly ineffective in older patients since many motor neurons have already been lost. Therefore, understanding nervous system (NS) physiology in SMA patients is essential.

Cannabinoid CB2 Receptors in Neurodegenerative Proteinopathies
Some of the most prevalent neurodegenerative disorders, including Alzheimer’s and Parkinson’s disease, are proteinopathies characterized by the accumulation of specific protein aggregates in the brain. Such misfolded protein aggregates can trigger modulation of the innate and adaptive immune systems and subsequently lead to chronic neuroinflammation that drives the onset and progression of neurodegenerative diseases. Since there is still no effective disease-modifying treatment, new therapeutic targets for neurodegenerative proteinopathies have been sought. The endocannabinoid system, and in particular the cannabinoid CB2 receptors, have been extensively studied, due to their important role in neuroinflammation, especially in microglial cells.

Translation Impairment in Neurodegeneration
Protein synthesis is a strictly controlled molecular process because of its central role in different key cellular events, including homeostasis maintenance and response to extra- and intracellular cues. Increasing evidence suggests a dysfunction of the translation machinery in different neurodegenerative disorders. These dysfunctions are characterized by the accumulation of pathological protein aggregates, which could reflect defects in both ribosome and ribosome-associated activities.

Migraine, Tension-Type Headache and Parkinson’s Disease
The relationship between migraine and tension-type headache (TTH) with Parkinson’s disease (PD) is controversial, while a common pathophysiological link remains obscure. The aim of researchers is to investigate the association between PD, migraine and TTH.

Post-Stroke Movement with Motion Capture and Musculoskeletal Modeling
Research of post-stroke locomotion via musculoskeletal (MSK) modeling has offered an unprecedented insight into pathological muscle function and its interplay with skeletal geometry and external stimuli. Advances in solving the dynamical system of post-stroke effort and the generic MSK models used have triggered noticeable improvements in simulating muscle activation dynamics of stroke populations.

Body Weight and Metabolic Rate Changes in Narcolepsy
Narcolepsy is a known auto-immune disease that presents mainly in the teenage years with irresistible sleep attacks. Patients with narcolepsy, especially NT1, have been found to have a high prevalence of obesity and other metabolic derangements. Compared to controls, patients with narcolepsy are more likely to be obese and have higher BMIs and waist circumferences. According to recent research, weight gain in narcolepsy patients may be higher during the disease's outset. Furthermore, the available data did not show any appreciable alterations in the levels of CSF melanin-concentrating hormone, plasma and CSF leptin, or serum growth hormone in relation to weight gain. Other mechanisms have been proposed, including a reduction in sympathetic tone, hormonal changes, changes in eating behavior and physical activity, and genetic predisposition. The association between increased body mass index and narcolepsy is well-recognized; the relationship between narcolepsy and other metabolic measures, such as body fat/muscle distribution and metabolic rate independent of BMI, is not well documented, and the available evidence is inconsistent. Future longitudinal studies with larger sample sizes are needed to assess BMR in patients with narcolepsy under a standard protocol at the outset of narcolepsy, with regular follow-up.

Measles Induced Encephalitis
Encephalitis, a well-known complication of measles, is inflammation of the brain parenchyma which is mostly due to the viral invasion of neurons. It presents with a variety of symptoms ranging from mild to severe depending on the extent of the damaged neurons.

Neuroinflammation and Neurodegenerative Disease Pathogenesis
The immune system encompasses two wings, innate immunity and adaptive immunity, which both work in harmony to help the body to fight diseases. The branch of innate immunity (nonspecific, natural immunity) has various roles in physiological and pathological processes. In part, it forms the front line of defense against infections and is implicated in tissue maintenance and the clearance of apoptotic cells and cellular remains. It stimulates inflammation, which indiscriminately attacks bacteria, viruses and other invaders quickly and does not require the presence of an external challenge. On other hand, the branch of the “adaptive” immune system (specific or acquired immunity) targets pathogens or strange molecules specifically, identifying them and marking them for destruction, and retains memories of previous challenges. The natural immune response is the first initiator, and it is the spearhead functioning to counter any neuroinflammation in the brain, thus including the neuroinflammation at the forefront of the Alzheimer’s disease (AD) pathology.

Neuroprotection and Non-Invasive Brain Stimulation
Non-Invasive Brain Stimulation (NIBS) techniques, such as transcranial Direct Current Stimulation (tDCS) and repetitive Magnetic Transcranial Stimulation (rTMS), are well-known non-pharmacological approaches to improve both motor and non-motor symptoms in patients with neurodegenerative disorders. Their use is of particular interest especially for the treatment of cognitive impairment in Alzheimer’s Disease (AD), as well as axial disturbances in Parkinson’s (PD), where conventional pharmacological therapies show very mild and short-lasting effects. However, their ability to interfere with disease progression over time is not well understood; recent evidence suggests that NIBS may have a neuroprotective effect, thus slowing disease progression and modulating the aggregation state of pathological proteins.
