The integrity of the blood-CSF barrier plays a major role in inflammation, but also in shielding the CNS from external and systemic-potentially toxic-factors. Here we report results of measurements of the albumin quotient-which is thought to mirror the integrity of the blood-CSF barrier-in 1059 patients with amyotrophic lateral sclerosis. The results were compared with groups of patients suffering from Alzheimer's disease, facial palsy and tension headache. The albumin quotient, an accepted measure of the blood-CSF barrier integrity, was not significantly different from control populations. In addition, we found that the albumin quotient correlated with survival of the patients; this effect was mainly driven by male patients and influenced by age, body mass index and diabetes mellitus. We conclude that the blood-CSF barrier is intact in this large cohort of patients with amyotrophic lateral sclerosis and that the albumin quotient correlates with survival. Whether this is important for the pathogenesis of the disease, requires mechanistic studies.

Delirium is a highly prevalent neuropsychiatric syndrome characterised by acute and fluctuating impairments in attention and cognition. Mechanisms driving delirium are poorly understood but it has been suggested that blood cytokines and chemokines cross the blood brain barrier during delirium, directly impairing brain function. It is not known whether these molecules reach higher brain levels when the blood cerebrospinal fluid barrier (BCSFB) is impaired.

The choroid plexus (ChP) is a vital brain structure that produces cerebrospinal fluid (CSF) and forms a selective barrier between the blood and CSF, essential for brain homeostasis. Composed of secretory epithelial cells, connective stroma, and a fenestrated vascular network, the ChP supports nutrient transport, immune surveillance, and the clearance of toxic by-products. Despite its significance in maintaining cerebral function, the mechanisms underlying its development and maturation remain poorly understood.

During gestation, the choroid plexus (ChP) produces protein-rich cerebrospinal fluid and matures prior to brain development. It is assumed that ChP dysfunction has a profound effect on developmental neuropsychiatric disorders, such as autism spectrum disorder (ASD). However, the mechanisms linking immature ChP to the onset of ASD remain unclear.

Background: The presence of intrathecal total IgG production is a hallmark of cerebrospinal fluid (CSF) characteristics in multiple sclerosis (MS). Herein, we systematically analyze how the intensity (instead of mere presence) of intrathecal total IgG production relates to basic CSF parameters in MS.
Methods: We retrospectively assessed clinical routine CSF findings from 390 therapy-naïve relapsing-remitting MS patients diagnosed according to 2017 revised McDonald criteria.

Reduced serum level of insulin-like growth factor 1 (IGF-1), a major regulator of perinatal development, in extremely preterm infants has been shown to be associated with neurodevelopmental impairment. To clarify the mechanism of IGF-1 transport at the blood-cerebrospinal fluid (CSF) barrier of the immature brain, we combined studies of in vivo preterm piglet and rabbit models with an in vitro transwell cell culture model of neonatal primary murine choroid plexus epithelial (ChPE) cells. We identified IGF-1-positive intracellular vesicles in ChPE cells and provided data indicating a directional transport of IGF-1 from the basolateral to the apical media in extracellular vesicles (EVs).
