Diagnosis of Alzheimer's disease: Llama antibodies detect cerebral lesions

Diagnosis of Alzheimer's disease: Llama antibodies detect cerebral lesions:

Dementia Big
The major challenge facing physicians treating Alzheimer’s is the ability to detect markers of the disease as early as possible. These markers, located in the brain, are difficult to access, hampering diagnosis. Using two types of llama antibody capable of crossing the blood-brain barrier, scientists from the Institut Pasteur, Inserm, the CNRS, the CEA, Pierre & Marie Curie and Paris Descartes Universities and Roche have developed a non-invasive approach to reach brain cells in a mouse model of the disease. Once in the brain, these llama antibodies can specifically mark and show amyloid plaques and neurofibrillary tangles, the two types of lesions that characterize Alzheimer’s disease. These results were published in the Journal of Controlled Release on October 7, 2016.
