Aducanumab, sold under the brand name Aduhelm, is a monoclonal antibody designed to treat Alzheimer's disease. It is a monoclonal antibody that targets aggregated forms (plaque) of amyloid beta (Aβ) found in the brains of people with Alzheimer's disease to reduce its buildup. [10] It was developed by Biogen and Eisai. [11] Aducanumab is given via intravenous infusion. [5] Aducanumab was ...
BLAZE was a phase II study that also concluded in 2014 and evaluated the effects of crenezumab in patients with mild-to-moderate Alzheimer's Disease, however its primary endpoint was changes in brain amyloid load, with secondary endpoints of changes in other biomarkers, cognition, global function, and activities of daily living. The resultant ...
The publishing journals have issued expressions of concern for studies related to the pharmacology. [17] [20] [21]Burns and Wang reported in 2008 that FLNA contains the high-affinity binding site of naloxone and naltrexone in preventing opioid tolerance and dependence, [17] and in 2020 that by disrupting that simufilam reduces the ultra-tight binding of amyloid beta 42 to the alpha-7 nicotinic ...
Processing of the amyloid precursor protein. BACE1 is the major beta secretase for the generation of amyloid-β peptides in the neurons. [9]Generation of the 40 or 42 amino acid-long amyloid-β peptides that aggregate in the brain of Alzheimer's patients requires two sequential cleavages of the amyloid precursor protein (APP).
A main theory behind the cause of Alzheimer’s disease is the build-up of the protein amyloid-beta in the brain. Researchers from the University of Cincinnati provide evidence suggesting it’s ...
Amyloid-related imaging abnormalities (ARIA) are abnormal differences seen in magnetic resonance imaging of the brain in patients with Alzheimer's disease. ARIA is associated with anti-amyloid drugs, particularly human monoclonal antibodies such as aducanumab. [1] There are two types of ARIA: ARIA-E and ARIA-H.
Lecanemab may cause amyloid-related imaging abnormalities (ARIA). ARIA is often asymptomatic, but serious and life-threatening events rarely may occur.ARIA most commonly presents as temporary swelling of the brain that usually resolves over time and may be accompanied by small spots of bleeding in or on the surface of the brain, though some people may have symptoms such as headache, confusion ...
Cerebral amyloid angiopathy (CAA) is a form of angiopathy in which amyloid beta peptide deposits in the walls of small to medium blood vessels of the central nervous system and meninges. [ 2 ] [ 3 ] The term congophilic is sometimes used because the presence of the abnormal aggregations of amyloid can be demonstrated by microscopic examination ...
