Targeting neurotherapeutic agents through the blood-brain barrier.
نویسنده
چکیده
The blood-brain barrier (BBB) is maintained by the endothelial tight junctions within the brain microvasculature. Most small-molecule neuropharmaceutical agents and virtually all large-molecule drugs do not cross the BBB. The BBB problem is the rate-limiting factor preventing the transfer of progress in the molecular neurosciences to the development of clinically effective neurotherapeutic agents. The future development of neurotherapeutic agents will be accelerated by the development of BBB drug-targeting technology.

REVIEW —Current Perspective— Brain Drug Targeting and Gene Technologies
Brain drug targeting technology is based on the application of four gene technologies that enable the delivery of drugs or genes across the blood-brain barrier (BBB) in vivo. I) Genetic engineering is used to produce humanized monoclonal antibodies that target endogenous BBB transporters and act as vectors for delivery of drugs or genes to the human brain. The conjugate of a neurotherapeutic an...
متن کاملIn Silico Design and Verification of LAMP-BDNF Chimeric Protein for Presentation of BDNF on the Surface of Exosomes for Drug Delivery Through Blood-Brain Barrier
Background and purpose: The mature form of brain-derived neurotrophic factor (BDNF) binds to BDNF/NT-3 growth factors receptor (Trk-B). This binding leads to activation of Ras–MAPK pathway which is integrated with cell growth and proliferation. The BDNF deficiency is correlated with various diseases and affects aging and miscellaneous. In the present study we aimed to design a chimeric LAMP-BDN...
متن کاملNew systems for delivery of drugs to the brain in neurological disease.
The restricted or regulated entry of most blood-borne substances into the brain has been recognised for more than a century. The blood-brain barrier (BBB)-shielding function provided by endothelial cells is important in the treatment of neurological diseases because this exclusion of foreign substances also restricts entry of many potentially therapeutic agents into the brain. The recent identi...
متن کاملThe effect of nanoparticle size on the probability to cross the blood-brain barrier: an in-vitro endothelial cell model
BACKGROUND During the last decade nanoparticles have gained attention as promising drug delivery agents that can transport through the blood brain barrier. Recently, several studies have demonstrated that specifically targeted nanoparticles which carry a large payload of therapeutic agents can effectively enhance therapeutic agent delivery to the brain. However, it is difficult to draw definite...
متن کاملEstrogen provides neuroprotection against brain edema and blood brain barrier disruption through both estrogen receptors α and β following traumatic brain injury
Objective(s):Estrogen (E2) has neuroprotective effects on blood-brain-barrier (BBB) after traumatic brain injury (TBI). In order to investigate the roles of estrogen receptors (ERs) in these effects, ER-α antagonist (MPP) and, ER-β antagonist (PHTPP), or non-selective estrogen receptors antagonist (ICI 182780) were administered. Materials and Methods: Ovariectomized rats were divided into 10 gr...
