Special Issue Information

Dear Colleagues,

The term “neurodegenerative diseases” (NDs) collectively defines a group of pathological conditions of the nervous system characterized by the degeneration of neurons. This group of disorders includes different diseases leading to dementia or motor neuron disfunction, resulting in disability. Among them, Alzheimer’s (AD) and Parkinson’s diseases (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS) have the greatest importance because of their devastating outcomes and enormous socio-economic impact. Although they have a variegated etiology, an increasing role in their pathology is ascribed to neuroinflammatory processes. Neuroinflammation may affect not only neurons but also non-neuronal astrocytes and microglia cells, as well as immune cells entering the nervous system. These cells cooperate in both the damage and the repair of diseased brain tissue. Interactions between cells and the extracellular environment have emerged as new targets for the treatment of neurodegenerative disorders. However, the heterogeneity of the molecular and cellular mechanisms underlying these diseases hinders efforts at slowing down the progression of these diseases and their effective treatment. Moreover, the availability of biomarkers with appropriate sensitivity and specificity that could predict treatment success is very limited.

Inflammatory and infectious diseases of the central nervous system (CNS) may also be involved in the pathogenesis of neurodegeneration. Microbial infection has emerged as a new risk factor for NDs, and new evidence supports the universal hypothesis that some bacteria, viruses, and even fungi could be involved not only in brain inflammation but also in neurodegeneration and dementia. The diagnosis of CNS infections and the identification of potential pathogenic pathways of these diseases are also topics of interest for this Special Issue, as well as the therapy and prevention of these diseases, including vaccination.

Studies on malignant primary brain tumors are also welcome. These tumors are a highly heterogeneous group of malignancies, with varied frequency within different age groups. Among them, glioblastoma is the most common and most malignant primary CNS tumor, affecting patients of all ages, from children to adults. Glioblastoma multiforme is an especially fatal tumor type, and only moderate progress has been achieved in its clinical management in recent years.

The goal of this Special Issue is to collect original research manuscripts, short communications, and reviews on the latest advances regarding new mechanisms of and therapeutics for neurological diseases, including neurodegeneration, neuroinflammation, and tumors of the central nervous system.

Topics of interest include (but are not limited to):

  • Biological mechanisms related to neurodegeneration, inflammation, and tumorigenesis within the central nervous system;
  • Neurodegenerative diseases as proteinopathies;
  • Relationship between neurodegeneration and inflammation;
  • New potential biomarkers of Alzheimer’s disease and other neurodegenerative diseases, including mild cognitive impairment, multiple sclerosis, Parkinson’s disease, Lewy body dementia, frontotemporal dementia, amyotrophic lateral sclerosis, Huntington’s disease, and prion diseases;
  • Prognostic value of biomarkers of neurodegeneration in the conversion from mild cognitive impairment to fully symptomatic dementia;
  • Cytokines, chemokines, and matrix metalloproteinases as prognostic factors in the carcinogenesis of CNS malignant tumors;
  • Mediators of inflammation, chemokines, and their receptors as novel tumor markers in malignant tumors of the central nervous system in relation to the histological type of tumors;
  • Relationships between COVID-19 and neurological diseases.

This Special Issue is supervised by Prof. Dr. Barbara Mroczko and assisted by our Topical Advisory Panel Member Dr. Kristina Mlinac-Jerković (University of Zagreb).

In addition to amyloid and tau pathology in the central nervous system (CNS), inflammatory processes and synaptic dysfunction are highly important mechanisms involved in the development and progression of dementia diseases. In the present study, we conducted a comparative analysis of selected pro-inflammatory proteins in the CNS with proteins reflecting synaptic damage and core biomarkers in mild cognitive impairment (MCI) and early Alzheimer’s disease (AD). To our knowledge, no studies have yet compared CXCL12 and CX3CL1 with markers of synaptic disturbance in cerebrospinal fluid (CSF) in the early stages of dementia. The quantitative assessment of selected proteins in the CSF of patients with MCI, AD, and non-demented controls (CTRL) was performed using immunoassays (single- and multiplex techniques). In this study, increased CSF concentration of CX3CL1 in MCI and AD patients correlated positively with neurogranin (r = 0.74; p < 0.001, and r = 0.40; p = 0.020, respectively), ptau181 (r = 0.49; p = 0.040), and YKL-40 (r = 0.47; p = 0.050) in MCI subjects. In addition, elevated CSF levels of CXCL12 in the AD group were significantly associated with mini-mental state examination score (r = −0.32; p = 0.040). We found significant evidence to support an association between CX3CL1 and neurogranin, already in the early stages of cognitive decline. Furthermore, our findings indicate that CXCL12 might be a useful marker for tract severity of cognitive impairment. Full article

Trace elements and metals play critical roles in the normal functioning of the central nervous system (CNS), and their dysregulation has been implicated in neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD). In a healthy CNS, zinc, copper, iron, and manganese play vital roles as enzyme cofactors, supporting neurotransmission, cellular metabolism, and antioxidant defense. Imbalances in these trace elements can lead to oxidative stress, protein aggregation, and mitochondrial dysfunction, thereby contributing to neurodegeneration. In AD, copper and zinc imbalances are associated with amyloid-beta and tau pathology, impacting cognitive function. PD involves the disruption of iron and manganese levels, leading to oxidative damage and neuronal loss. Toxic metals, like lead and cadmium, impair synaptic transmission and exacerbate neuroinflammation, impacting CNS health. The role of aluminum in AD neurofibrillary tangle formation has also been noted. Understanding the roles of these elements in CNS health and disease might offer potential therapeutic targets for neurodegenerative disorders. The Codex Alimentarius standards concerning the mentioned metals in foods may be one of the key legal contributions to safeguarding public health. Further research is needed to fully comprehend these complex mechanisms and develop effective interventions. Full article
