Macrophages as Nanocarriers for Drug Delivery: Novel Therapeutics for Central Nervous System Diseases.

Journal of Nanoscience and Nanotechnology

Abstract

Many central nervous system (CNS) diseases were thought to be untreatable due to the presence of the blood-brain barrier (BBB). The chemokine gradients secreted from CNS parenchyma can induce macrophage migration to the brain, induce firm adherence to the endothelium of BBB, and eventually to enter the brain parenchyma. Macrophages migrating into CNS can promote neuron regeneration, induce inflammation and angiogenesis. These properties can potentially allow macrophages to act as carriers for drug/nano formulations across the BBB, and reach the potential target sites. Many nanomaterials cannot be used for the management of CNS diseases because of their low carrying efficiency. Macrophage which transports nanomaterials to pathological sites is rendered as an attractive tool for the transportation of drugs to previously inaccessible regions within the brain parenchyma. Nanomaterials engulfed by macrophages can be released at target sites, and be used for therapeutic or diagnostic purposes. In this review, we focus on macrophages as the cell-carrier to deliver nano-drugs into CNS, describe the biological behavior of macrophages during pathological conditions and discuss the application of cell drug delivery system in recent years.

Blood Brain Barrier & Cytokines

Some cytokines are able to cross the blood brain barrier through transport systems and enter the cerebrospinal fluid and interstitial fluid spaces. Here is the latest research on cytokines crossing the blood brain barrier and how this can affect tissues within the CNS.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
