Protollin

From Wikipedia, the free encyclopedia

Protollin is a drug initially formulated as a vaccine adjuvant.[1][2] It is composed of lipopolysaccharides derived from the Shigella flexneri or Pleisiomonas shigelloides bacterium combined with hydrophobic outer membrane proteins derived from Neisseria meningitidis.[3] [4]

On November 16, 2021, Brigham and Women's Hospital announced that it was beginning a Phase I clinical trial of Protollin as a nasally-delivered vaccine to activate the body's immune response against amyloid proteins that form in the brain and are thought to contribute to the symptoms of Alzheimer's disease.[5][6]
