Webb15 mars 2024 · Because the blood-brain barrier blocks entry to all but a tiny subset of small molecules, neurological conditions such as Alzheimer’s, multiple sclerosis, brain tumors, and depression are exceedingly difficult to treat. Having control over the barrier will be helpful for future drug delivery ventures.
WebbCONCLUSIONS. Although MSCs undoubtedly have immunomodulatory and regenerative therapeutic properties, attempting to apply MSCs “as is” without a clear target has proved to be unsuccessful in most clinical studies. Without a well-defined target, developing more effective “next-generation” MSC therapies will be limited.
