Special Issue Information

Dear Colleagues,

In recent years, interest has grown in cerebrospinal fluid (CSF) as a physiological fluid supporting brain development, function and health. Attention has focused on the source of CSF, the choroid plexus epithelium, as the compoisition of CSF is unique and controlled. The role of CSF in brain development, normal function and health of the brain, is becoming clear, particularly in metabolic processes, supply of nutrients, metabolies and vitamins. Then, we have the vital role of CSF in removal of metabolic and cellular waste products including amyloid and cellular breakdown products. Here, the high volume of CSF production becomes important as decreased CSF output has bene linked to amyloid deposition and dementia. The lack of efficient drainage also clearly leads to metabolic dysfunction, specifically in folate metabolism but no doubt in other pathways as well. The recent hot topic in CSF research is, of course, the glymphatic pathway which has certain issues in its application to the global fluid dynamics of the brain since the perivascular spaces exist only in the topmost layer of the brain. This Special Issue will hopefully explore the different aspects of CSF biology, physiology and functions from different directions and fuel further interactions, debate and research to find answers to questions on this poorly studied physiological fluid.

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.

The molecular mechanisms underlying the development of posthemorrhagic hydrocephalus (PHH) remain incompletely understood. As the disease pathogenesis often cannot be attributed to visible cerebrospinal fluid (CSF) drainage obstructions, we here aimed to elucidate whether elevated CSF osmolality following subarachnoid hemorrhage (SAH) could potentiate the formation of ventricular fluid, and thereby contribute to the pathological CSF accumulation observed in PHH. The CSF osmolality was determined in 32 patients with acute SAH after external ventricular drainage (EVD) placement and again upon EVD removal and compared with the CSF osmolality from 14 healthy control subjects undergoing vascular clipping of an unruptured aneurism. However, we found no evidence of elevated CSF osmolality or electrolyte concentration in patients with SAH when compared to that of healthy control subjects. We detected no difference in CSF osmolality and electrolyte content in patients with successful EVD weaning versus those that were shunted due to PHH. Taken together, elevated CSF osmolality does not appear to underlie the development of PHH following SAH. The pathological CSF accumulation observed in this patient group must thus instead be attributed to other pathological alterations associated with the abnormal presence of blood within the CSF compartments following SAH.
