Nanosystems at Nexus: Navigating Nose-to-Brain Delivery for Glioblastoma Treatment.

Glioblastoma multiforme (GBM) is considered to be one of the most devastating brain tumors with a shorter life expectancy. Several factors contribute to the dismal prognosis of GBM patients including the complicated nature of GBM, the ability of tumor cells to resist treatment, and the difficulty of delivering drugs to the brain because of barriers like the blood-brain barrier (BBB) and blood-tumor barrier (BTB). The unique challenges posed by the BBB in delivering therapeutic agents to the brain have led to the development of innovative nanotechnology-based approaches.

Zein-based nanoparticulate systems: a journey through fabrication, targeting strategies and biomedical applications.

Zein, a plant-based protein obtained from the endosperm of corn ( L.) received colossal attention in recent years due to its promising features like being economical, mucoadhesive, gastro-resistant, biocompatible and aids to load hydrophilic and hydrophobic therapeutic agents. It can be employed for the fabrication of various drug delivery systems such as nanoparticles, micelles, hydrogels, nanofibers and films.

Gut instincts: Unveiling the connection between gut microbiota and Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative disorder marked by neuroinflammation and gradual cognitive decline. Recent research has revealed that the gut microbiota (GM) plays an important role in the pathogenesis of AD through the microbiota-gut-brain axis. However, the mechanism by which GM and microbial metabolites alter brain function is not clearly understood.

Functionalized liposomes: an enticing nanocarrier for management of glioma.

Glioma is one of the most severe central nervous systems (CNS)-specific tumors, with rapidly growing malignant glial cells accounting for roughly half of all brain tumors and having a poor survival rate ranging from 12 to 15 months. Despite being the most often used technique for glioma therapy, conventional chemotherapy suffers from low permeability of the blood-brain barrier (BBB) and blood-brain tumor barrier (BBTB) to anticancer drugs. When it comes to nanocarriers, liposomes are thought of as one of the most promising nanocarrier systems for glioma treatment.
