MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024821 A) filed by Vignan Institute Of Pharmaceutical Technology, Visakhapatnam, Andhra Pradesh, on March 2, for 'bioinspired exosome-mimicking vesicles for crossing the blood-brain barrier in alzheimer's treatment.'
Inventor(s) include P. N. Mallikarjun; Y. Srinivasa Rao; G. Chandrasekhara Rao; M. Saritha; and P. V. Kamala Kumari.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a pioneering bioinspired approach to Alzheimer's treatment by developing exosome-mimicking vesicles that efficiently cross the blood-brain barrier (BBB) to deliver therapeutic agents directly to affected brain regions. Drawing inspiration from natural exosomes, these synthetic vesicles are engineered with surface proteins and lipid compositions that mimic cellular communication signals, enabling targeted penetration without triggering immune responses. The formulation incorporates neuroprotective compounds, such as anti-amyloid peptides or tau inhibitors, encapsulated within a stable bilayer structure, achieving up to 50% higher brain uptake compared to conventional nanoparticles. By utilizing biodegradable materials and scalable production techniques, the vesicles offer sustained release over 48 hours, reducing neuroinflammation and plaque buildup in preclinical models. This technology promises a non-invasive alternative to current therapies, potentially slowing disease progression and improving cognitive function in Alzheimer's patients, with broader implications for other neurological disorders."
