New Delivery Method Paves the Way for Anti-Inflammatory Treatments in Brain Diseases: Study
Advertisement
Oregon State University researchers have discovered a way to get anti-inflammatory medicine across the blood-brain barrier, opening the door to potential new therapies for a range of conditions, including Alzheimer’s disease, multiple sclerosis, Parkinson’s disease and cancer cachexia. Findings were published today in Advanced Healthcare Materials.
The delivery method involves specially engineered nanoparticles, tiny bits of matter no larger than 100 billionths of a meter. Tested in a mouse model, the dual peptide-functionalized polymeric nanocarriers reached their intended destination, the hypothalamus, and delivered a drug that inhibits a key protein associated with inflammation.
People with cancer cachexia will lose weight even if they eat, and not just fat but muscle mass as well. The debilitating syndrome affects up to 80% of advanced cancer patients and kills as many as 30% of the cancer patients it afflicts.
The systemic delivery of anti-inflammatory agents, including the IRAK4 inhibitors used in this research, to the hypothalamus presents significant challenges, Taratula said, mainly because of the restrictive nature of the blood-brain barrier.
