Special Issue Information

Dear Colleagues,

Brain ageing is a complex process of all vertebrate organisms and is influenced by systemic, genetic, and environmental factors. In course of ageing, the brain undergoes general morpho-physiological changes that include shrinkage of brain mass and myelin, decline of synaptic connections, and decreased neurotransmitter release. These modifications are associated with cognitive decline in information processing speed, memory, reasoning, and executive function, in addition to decreased well-being and increased symptoms of low mood. Furthermore, ageing is one of the major contributing factors for neurodegenerations and other brain diseases. Much of what we know about the impact of ageing on brain comes from model organisms (either vertebrate and invertebrates), which have been instrumental to identify factors that cause and modulate the ageing process. In this collection, we aim to address various aspects of the neurobiology of ageing and ageing related disorders, including a) new experimental approaches to modulate the ageing process with consequences on brain morpho-physiology; b) the identification of genetic and environmental factors related to brain ageing; and c) new imaging techniques and bioinformatics approaches to detect changes in the brain during ageing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cognitive deficiency is one of the fundamental characteristics of late-onset depression (LOD). Luteolin (LUT) possesses antidepressant, anti-aging, and neuroprotective properties, which can dramatically enhance cognition. The altered composition of cerebrospinal fluid (CSF), which is involved in neuronal plasticity and neurogenesis, directly reflects the physio-pathological status of the central nervous system. It is not well known whether the effect of LUT on LOD is in association with a changed CSF composition. Therefore, this study first established a rat model of LOD and then tested the therapeutic effects of LUT using several behavioral approaches. A gene set enrichment analysis (GSEA) was used to evaluate the CSF proteomics data for KEGG pathway enrichment and Gene Ontology annotation. We combined network pharmacology and differentially expressed proteins to screen for key GSEA–KEGG pathways as well as potential targets for LUT therapy for LOD. Molecular docking was adopted to verify the affinity and binding activity of LUT to these potential targets. The outcomes demonstrated that LUT improved the cognitive and depression-like behaviors in LOD rats. LUT may exert therapeutic effects on LOD through the axon guidance pathway. Five axon guidance molecules—EFNA5, EPHB4, EPHA4, SEMA7A, and NTNG—as well as UNC5B, L1CAM, and DCC, may be candidates for the LUT treatment of LOD. Full article
