  2. Cerebral amyloid angiopathy - Wikipedia

    en.wikipedia.org/wiki/Cerebral_amyloid_angiopathy

    CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...

  3. Amyloid plaques - Wikipedia

    en.wikipedia.org/wiki/Amyloid_plaques

    The diagnosis of Alzheimer's disease typically requires a microscopic analysis of plaques and tangles in brain tissue, usually at autopsy. [40] However, Aβ plaques (along with cerebral Aβ-amyloid angiopathy ) can be detected in the brains of living subjects by preparing radiolabeled agents that bind selectively to Aβ deposits in the brain ...

  4. Neuroinflammation - Wikipedia

    en.wikipedia.org/wiki/Neuroinflammation

    As the most abundant immune cells in the brain, microglia are important to the brain's defense against injury. The major caveat of these cells comes from the fact that their ability to promote recovery mechanism with anti-inflammatory factors, is inhibited by their secondary ability to make a large amount of pro-inflammatory cytokines.

  6. Role of microglia in disease - Wikipedia

    en.wikipedia.org/wiki/Role_of_microglia_in_disease

    Microglia synthesize amyloid precursor protein (APP) in response to excitotoxic injury. [2] Plaques result from abnormal proteolytic cleavage of membrane bound APP. [2] Amyloid plaques can stimulate microglia to produce neurotoxic compounds such as cytokines, excitotoxin, nitric oxide and lipophylic amines, which all cause neural damage. [6]

  8. AL amyloidosis - Wikipedia

    en.wikipedia.org/wiki/AL_amyloidosis

    Amyloid light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form of systemic amyloidosis. [1] The disease is caused when a person's antibody-producing cells do not function properly and produce abnormal protein fibers made of components of antibodies called light chains. These light chains come together to form ...

  9. Amyloid - Wikipedia

    en.wikipedia.org/wiki/Amyloid

    To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR).
