Antiphospholipid syndrome (APS) is an autoimmune process that increases the risk of arterial and venous thrombosis. The mechanism of damage to the central nervous system (CNS) can be not only due to thrombosis, but also antiphospholipid antibodies (APA) circulating in the peripheral blood. The latter can damage the cerebral vascular endothelium, alter the resistance of the blood-brain barrier and penetrate into the central nervous system, exerting a damaging effect on astroglia and neurons, as evidenced by the release of neurospecific proteins into the peripheral bloodstream. The role of APS in developing cerebral ischemia, migraine, epilepsy, chorea, transverse myelitis, multiple sclerosis, cognitive impairment and mental disorders, as well as the peripheral nervous system is described. It should also be noted about a role of APS for emerging neurological disorders in COVID-19, enabled apart from thrombogenesis due to APA via 2 potential mechanisms - molecular mimicry and neoepitope formation. Further study of the APS pathogenesis and interdisciplinary interaction are necessary to develop effective methods for patient management.

Stimulating Factor

The colony-stimulating factor 1 receptor (CSF1R) is a key tyrosine kinase transmembrane receptor modulating microglial homeostasis, neurogenesis, and neuronal survival in the central nervous system (CNS). CSF1R, which can be proteolytically cleaved into a soluble ectodomain and an intracellular protein fragment, supports the survival of myeloid cells upon activation by two ligands, colony stimulating factor 1 and interleukin 34. CSF1R loss-of-function mutations are the major cause of adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) and its dysfunction has also been implicated in other neurodegenerative disorders including Alzheimer’s disease (AD). Here, we review the physiological functions of CSF1R in the CNS and its pathological effects in neurological disorders including ALSP, AD, frontotemporal dementia and multiple sclerosis. Understanding the pathophysiology of CSF1R is critical for developing targeted therapies for related neurological diseases.

The Central Nervous System

Pericytes are perivascular multipotent cells located on capillaries. Although pericytes are discovered in the nineteenth century, recent studies have found that pericytes play an important role in maintaining the blood—brain barrier (BBB) and regulating the neurovascular system. In the neurovascular unit, pericytes perform their functions by coordinating the crosstalk between endothelial, glial, and neuronal cells. Dysfunction of pericytes can lead to a variety of diseases, including stroke and other neurological disorders. Recent studies have suggested that pericytes can serve as a therapeutic target in ischemic stroke. In this review, we first summarize the biology and functions of pericytes in the central nervous system. Then, we focus on the role of dysfunctional pericytes in the pathogenesis of ischemic stroke. Finally, we discuss new therapies for ischemic stroke based on targeting pericytes.

The Central Nervous System

Metallothioneins are a family of proteins which are able to bind metals intracellularly, so their main function is to regulate the cellular metabolism of essential metals. There are 4 major isoforms of MTs (I–IV), three of which have been localized in the central nervous system. MT-I and MT-II have been localized in the spinal cord and brain, mainly in astrocytes, whereas MT-III has been found mainly in neurons. MT-I and MT-II have been considered polyvalent proteins whose main function is to maintain cellular homeostasis of essential metals such as zinc and copper, but other functions have also been considered: detoxification of heavy metals, regulation of gene expression, processes of inflammation, and protection against free radicals generated by oxidative stress. On the other hand, the MT-III has been related in events of pathogenesis of neurodegenerative diseases such as Parkinson and Alzheimer. Likewise, the participation of MTs in other neurological disorders has also been reported. This review shows recent evidence about the role of MT in the central nervous system and its possible role in neurodegenerative diseases as well as in brain disorders.

With Memory

: Neurological disorders, such as epilepsy, dementia, Parkinson’s disease, and Alzheimer’s disease, occur due to disorganization of the neurons in the nervous system. Disturbances in the nervous system cause problems with memory, senses and moods. In order to treat such disorders, scientists have been working extensively by using different approaches. Nanoneurotechnology has emerged as a promising tool to manage these complicated disorders, where nanoparticles with their tunable properties such as size, shape, increased solubility, biodegradability, surface area and sharp penetration through the biological barriers target the central nervous system. This technology targets damaged neurons without affecting healthy neurons and Blood-Brain Barrier (BBB). In this review, we discuss neurological disorders and challenges in the diagnosis and treatment of neurological disorders by emphasizing the role of tailorable gold nanoparticles for therapeutic drug approaches.

Context: Neurodegenerative diseases (NDs) are neurological disorders characterized by the degeneration of the central nervous system (CNS). Studies have examined interactions between long non-coding RNAs (lncRNAs) and functioning of the CNS in NDs. In this study, we summarized the role of different lncRNAs in most NDs. Methods: In this study, different papers published between years 2003 and 2020 were reviewed. Results: LncRNAs can play a significant role in the development of brain disorders. Conclusions: The dysregulation of lncRNAs has been shown to affect NDs such as Alzheimer's disease (AD) and Parkinson’s diseases (PD). In this review, we compiled recent findings related to the main lncRNAs associated with brain disorders.

Privileged Site

The central nervous system (CNS) was once considered to be an immune-privileged area. However, increasing evidence shows that the central nervous system is not an immune-privileged but is an active surveillance site. There is a bi-directional communication between the central nervous system and immune system. Normally, immune cells migrate into the central nervous system microenvironment through choroid plexus and interact with the central nervous system resident cells through either through neuromediators or immunomediators. This finding has led to a significant interest in neuroimmunological interactions and investigation onto the role of the immune system in the pathology of various neurological disorders and examine whether it can be targeted to produce novel therapeutic strategies.

The Central Nervous System

Disorders of the musculoskeletal system in school-age children occupy 1-2 places in the structure of functional abnormalities. Cognitive impairment without organic damage to the central nervous system is detected in 30-56% of healthy school children. Along with the increase in the incidence rate, the demand for rehabilitation systems, which allow patients to return to normal life as soon as possible and maintain the motivation for the rehabilitation process, is also growing. Adaptation of rehabilitation techniques, ease of equipment management, availability of specially trained personnel and availability of technical support for complexes becomes important.
