Patent number: 11635439Abstract: Described herein are devices and methods for simultaneously expressing amyloid precursor protein and TonB protein. These devices and methods increase the production of these two proteins while also minimizing costs, making the proteins more widely accessible for medical research purposes, including the development of diagnostic tests for numerous diseases associated with elevated production of amyloid proteins. The amyloid precursor protein and TonB produced by the devices and methods described herein, as well as the devices themselves, can be used in experiments designed to model the interactions between metals and amyloids such as ?-amyloid that are characteristic of numerous diseases such as Alzheimer's. Finally, provided herein are diagnostic tests that can detect Alzheimer's disease in samples from patients; the tests are sensitive enough to identify diseases such as Alzheimer's even at pre-clinical stages, before the appearance of symptoms.Type: GrantFiled: June 17, 2020Date of Patent: April 25, 2023Assignee: Bio Capital Holdings, LLCInventors: Raul Cuero Rengifo, Diana Vasquez Forero, Juliana Londoño Murillo

Patent number: 7314724Abstract: Laminin and specific laminin-derived protein fragments are disclosed as potent inhibitors of Alzheimer's disease type amyloidoses. A specific region is identified within laminin which interacts with the Alzheimer's disease beta-amyloid protein and contributes to the observed inhibitory and therapeutic effects. A prominent ˜130 kilodalton band in laminin was found in human serum and cerebrospinal fluid which primarily interacted with A? as determined by ligand blotting methodology. This ˜130 kilodalton laminin fragment is known as the E8 fragment and is also believed to consist of the globular domains of the laminin A chain. The interaction of specific laminin fragments such as the newly discovered ˜130 kDa protein is believed to bind A? in biological fluids and keep it in a soluble state.Type: GrantFiled: August 22, 2001Date of Patent: January 1, 2008Assignee: University of WashingtonInventors: Gerardo Castillo, Alan D.
