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.

Modifying reaction time tasks parameters in the automated IntelliCage identifies heightened impulsivity and impaired attention in the 3xTg-AD model of Alzheimer's disease.

Background: The 3xTg-AD transgenic mouse model of Alzheimer's disease (AD) is an important tool to investigate the relationship between development of pathological amyloid-β (Aβ) and tau, neuroinflammation, and cognitive impairments. Traditional behavioral tasks assessing aspects of learning and memory, such as mazes requiring spatial navigation, unfortunately suffer from several shortcomings, including the stress of human handling and not probing species-typical behavior. The automated IntelliCage system was developed to circumvent such issues by testing mice in a social environment while measuring multiple aspects of cognition.
