The rise of antimicrobial resistance has made necessary the increase of the antibacterial arsenal against multidrug-resistant bacteria. In this context, colistin has re-emerged as a first-line antibiotic in critical situations despite its nephro- and neuro- toxicity at peripheral level. However, the mechanism underlying its toxicity remains unknown, particularly in relation to the central nervous system (CNS).

Permeability is a measure of the degree to which cells can transport molecules across biological barriers. Units of permeability are distance per unit time (typically cm/s), where accurate measurements are needed to define drug delivery in homeostasis and to model dysfunction occurring during disease. This perspective offers a set of community-led guidelines to benchmark permeability data across multidisciplinary approaches and different biological contexts.

Background: The presence of diffuse brain damage in normal-appearing white matter (NAWM) and gray matter (NAGM) in neuromyelitis optica spectrum disorder (NMOSD) remains controversial. We aimed to address this controversy by applying a multiparametric MRI approach. Additionally, the association between MRI metrics and clinical variables was explored.

Ferritin nanocarriers, which can penetrate the blood-brain barrier (BBB), have gained significant research interest for the diagnosis and treatment of central nervous system (CNS) diseases, including gliomas, Alzheimer's disease, and brain metastases. In recent years, ferritin has been proved as a candidate to cross the BBB using receptor-mediated transcytosis (RMT) mechanism through transferrin receptor 1 (TfR1) which is overexpressed in the cells of the BBB. Various types of cargo molecules, including therapeutics, imaging agents, nucleic acids, and metal nanoparticles, have been incorporated into ferritin nanocages for the diagnosis and treatment of CNS diseases.

Parkinson's disease (PD) is a progressive disorder that affects the nervous system and causes regions of the brain to deteriorate. In this study, we investigated the effects of MR-guided focused ultrasound (MRgFUS) for the delivery of human mesenchymal stem cells (MSCs) on the 6-hydroxydopamine (6-HODA)-induced PD rat model. MRgFUS-induced blood-brain barrier (BBB) permeability modulation was conducted using an acoustic controller with the targets at the striatum (ST) and SN.
