Cerebral Amyloid Angiopathy: A heterogeneous group of sporadic or familial disorders characterized by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES. Clinical features include multiple, small lobar CEREBRAL HEMORRHAGE; cerebral ischemia (BRAIN ISCHEMIA); and CEREBRAL INFARCTION. Cerebral amyloid angiopathy is unrelated to generalized AMYLOIDOSIS. Amyloidogenic peptides in this condition are nearly always the same ones found in ALZHEIMER DISEASE. (from Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., 2005)Cerebral Amyloid Angiopathy, Familial: A familial disorder marked by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES.Amyloid beta-Peptides: Peptides generated from AMYLOID BETA-PEPTIDES PRECURSOR. An amyloid fibrillar form of these peptides is the major component of amyloid plaques found in individuals with Alzheimer's disease and in aged individuals with trisomy 21 (DOWN SYNDROME). The peptide is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue.Amyloid: A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.Cerebral Hemorrhage: Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.Plaque, Amyloid: Accumulations of extracellularly deposited AMYLOID FIBRILS within tissues.Alzheimer Disease: A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)Amyloidosis: A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Vasculitis, Central Nervous System: Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)Amyloid beta-Protein Precursor: A single-pass type I membrane protein. It is cleaved by AMYLOID PRECURSOR PROTEIN SECRETASES to produce peptides of varying amino acid lengths. A 39-42 amino acid peptide, AMYLOID BETA-PEPTIDES is a principal component of the extracellular amyloid in SENILE PLAQUES.Cerebral Arteries: The arterial blood vessels supplying the CEREBRUM.Congo Red: An acid dye used in testing for hydrochloric acid in gastric contents. It is also used histologically to test for AMYLOIDOSIS.Cystatins: A homologous group of endogenous CYSTEINE PROTEINASE INHIBITORS. The cystatins inhibit most CYSTEINE ENDOPEPTIDASES such as PAPAIN, and other peptidases which have a sulfhydryl group at the active site.Siderosis: A form of pneumoconiosis resulting from inhalation of iron in the mining dust or welding fumes.Intracranial Hemorrhages: Bleeding within the SKULL, including hemorrhages in the brain and the three membranes of MENINGES. The escape of blood often leads to the formation of HEMATOMA in the cranial epidural, subdural, and subarachnoid spaces.Apolipoprotein E4: A major and the second most common isoform of apolipoprotein E. In humans, Apo E4 differs from APOLIPOPROTEIN E3 at only one residue 112 (cysteine is replaced by arginine), and exhibits a lower resistance to denaturation and greater propensity to form folded intermediates. Apo E4 is a risk factor for ALZHEIMER DISEASE and CARDIOVASCULAR DISEASES.Neurofibrillary Tangles: Abnormal structures located in various parts of the brain and composed of dense arrays of paired helical filaments (neurofilaments and microtubules). These double helical stacks of transverse subunits are twisted into left-handed ribbon-like filaments that likely incorporate the following proteins: (1) the intermediate filaments: medium- and high-molecular-weight neurofilaments; (2) the microtubule-associated proteins map-2 and tau; (3) actin; and (4) UBIQUITINS. As one of the hallmarks of ALZHEIMER DISEASE, the neurofibrillary tangles eventually occupy the whole of the cytoplasm in certain classes of cell in the neocortex, hippocampus, brain stem, and diencephalon. The number of these tangles, as seen in post mortem histology, correlates with the degree of dementia during life. Some studies suggest that tangle antigens leak into the systemic circulation both in the course of normal aging and in cases of Alzheimer disease.Presenilin-1: Integral membrane protein of Golgi and endoplasmic reticulum. Its homodimer is an essential component of the gamma-secretase complex that catalyzes the cleavage of membrane proteins such as NOTCH RECEPTORS and AMYLOID BETA-PEPTIDES precursors. PSEN1 mutations cause early-onset ALZHEIMER DISEASE type 3 that may occur as early as 30 years of age in humans.Cerebral Arterial Diseases: Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.Apolipoproteins E: A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.Meninges: The three membranes that cover the BRAIN and the SPINAL CORD. They are the dura mater, the arachnoid, and the pia mater.Blood Vessels: Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins).Cystatin C: An extracellular cystatin subtype that is abundantly expressed in bodily fluids. It may play a role in the inhibition of interstitial CYSTEINE PROTEASES.Cerebrospinal Fluid Proteins: Proteins in the cerebrospinal fluid, normally albumin and globulin present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. (Brain and Bannister's Clinical Neurology, 7th ed, p221)Mice, Transgenic: Laboratory mice that have been produced from a genetically manipulated EGG or EMBRYO, MAMMALIAN.Cerebrovascular Disorders: A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Dementia: An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.Autopsy: Postmortem examination of the body.Dementia, Vascular: An imprecise term referring to dementia associated with CEREBROVASCULAR DISORDERS, including CEREBRAL INFARCTION (single or multiple), and conditions associated with chronic BRAIN ISCHEMIA. Diffuse, cortical, and subcortical subtypes have been described. (From Gerontol Geriatr 1998 Feb;31(1):36-44)Alkenes: Unsaturated hydrocarbons of the type Cn-H2n, indicated by the suffix -ene. (Grant & Hackh's Chemical Dictionary, 5th ed, p408)Apolipoprotein E2: One of three major isoforms of apolipoprotein E. In humans, Apo E2 differs from APOLIPOPROTEIN E3 at one residue 158 where arginine is replaced by cysteine (R158--C). In contrast to Apo E3, Apo E2 displays extremely low binding affinity for LDL receptors (RECEPTORS, LDL) which mediate the internalization and catabolism of lipoprotein particles in liver cells. ApoE2 allelic homozygosity is associated with HYPERLIPOPROTEINEMIA TYPE III.Peptide Fragments: Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Serum Amyloid A Protein: An ACUTE PHASE REACTION protein present in low concentrations in normal sera, but found at higher concentrations in sera of older persons and in patients with AMYLOIDOSIS. It is the circulating precusor of amyloid A protein, which is found deposited in AA type AMYLOID FIBRILS.Cerebral Cortex: The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulchi. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.Brain Diseases: Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.Blood-Brain Barrier: Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.Microcirculation: The circulation of the BLOOD through the MICROVASCULAR NETWORK.
Cerebral amyloid angiopathy is a pathogenic lesion in Alzheimer's disease due to a novel presenilin 1 mutation. (1/15)The dense-cored plaques are considered the pathogenic type of amyloid deposition in Alzheimer's disease brains because of their predominant association with dystrophic neurites. Nevertheless, in > 90% of cases of Alzheimer's disease amyloid is also deposited in cerebral blood vessel walls (congophilic amyloid angiopathy; CAA) but its role in Alzheimer's disease pathogenesis remains enigmatic. Here, we report a family (family GB) in which early-onset Alzheimer's disease was caused by a novel presenilin 1 mutation (L282V). This was unusually severe CAA reminiscent of the Flemish amyloid precursor protein (A692G) mutation we reported previously, which causes Alzheimer's disease and/or cerebral haemorrhages. In family GB, however, the disease presented as typical progressive Alzheimer's disease in the absence of strokes or stroke-like episodes. Similarly, neuroimaging studies and neuropathological examination favoured a degenerative over a vascular dementia. Interestingly, an immunohistochemical study revealed that, similar to causing dense-cored amyloid plaques, CAA also appeared capable of instigating a strong local dystrophic and inflammatory reaction. This was suggested by the observed neuronal loss, the presence of tau- and ubiquitin-positive neurites, micro- and astrogliosis, and complement activation. Together, these data suggest that, like the dense-cored neuritic plaques, CAA might represent a pathogenic lesion that contributes significantly to the progressive neurodegeneration that occurs in Alzheimer's disease.

Vitamin E but not 17beta-estradiol protects against vascular toxicity induced by beta-amyloid wild type and the Dutch amyloid variant. (2/15)Amyloid beta-peptide (Abeta) fibril deposition on cerebral vessels produces cerebral amyloid angiopathy that appears in the majority of Alzheimer's disease patients. An early onset of a cerebral amyloid angiopathy variant called hereditary cerebral hemorrhage with amyloidosis of the Dutch type is caused by a point mutation in Abeta yielding Abeta(Glu22-->Gln). The present study addresses the effect of amyloid fibrils from both wild-type and mutated Abeta on vascular cells, as well as the putative protective role of antioxidants on amyloid angiopathy. For this purpose, we studied the cytotoxicity induced by Abeta(1-40 Glu22-->Gln) and Abeta(1-40 wild-type) fibrils on human venule endothelial cells and rat aorta smooth muscle cells. We observed that Abeta(Glu22-->Gln) fibrils are more toxic for vascular cells than the wild-type fibrils. We also evaluated the cytotoxicity of Abeta fibrils bound with acetylcholinesterase (AChE), a common component of amyloid deposits. Abeta(1-40 wild-type)-AChE fibrillar complexes, similar to neuronal cells, resulted in an increased toxicity on vascular cells. Previous reports showing that antioxidants are able to reduce the toxicity of Abeta fibrils on neuronal cells prompted us to test the effect of vitamin E, vitamin C, and 17beta-estradiol on vascular damage induced by Abeta(wild-type) and Abeta(Glu22-->Gln). Our data indicate that vitamin E attenuated significantly the Abeta-mediated cytotoxicity on vascular cells, although 17beta-estradiol and vitamin C failed to inhibit the cytotoxicity induced by Abeta fibrils.

RAGE (yin) versus LRP (yang) balance regulates alzheimer amyloid beta-peptide clearance through transport across the blood-brain barrier. (3/15)Accumulation of amyloid beta-peptide (Abeta) in the central nervous system (CNS) may initiate pathogenic cascades mediating neurovascular and neuronal dysfunctions associated with the development of cerebral beta-amyloidosis and cognitive decline in patients with Alzheimer disease (AD) and with related familial cerebrovascular disorders. Whether Abeta-related pathology in the CNS is reversible or not and what key therapeutic targets are controlling Abeta/amyloid levels in the aging brain remain debatable. In this article, we summarize recent evidence why the receptor for advanced glycation end products and low-density lipoprotein receptor related protein 1 in the vascular CNS barriers are critical for regulation of Abeta homeostasis in the CNS and how altered activities in these 2 receptors at the blood-brain barrier may contribute to the CNS Abeta accumulation resulting in neuroinflammation, disconnect between the cerebral blood flow and metabolism, altered synaptic transmission, neuronal injury, and amyloid deposition into parenchymal and neurovascular lesions. We briefly discuss the potential of advanced glycation end products and low-density lipoprotein receptor related protein 1-based therapeutic strategies to control brain Abeta in animal models of AD and ultimately in patients with AD and related familial cerebrovascular beta-amyloidoses.

Reducing cerebral microvascular amyloid-beta protein deposition diminishes regional neuroinflammation in vasculotropic mutant amyloid precursor protein transgenic mice. (4/15)Cerebral microvascular amyloid-beta (Abeta) protein deposition is emerging as an important contributory factor to neuroinflammation and dementia in Alzheimer's disease and related familial cerebral amyloid angiopathy disorders. In particular, cerebral microvascular amyloid deposition, but not parenchymal amyloid, is more often correlated with dementia. Recently, we generated transgenic mice (Tg-SwDI) expressing the vasculotropic Dutch (E693Q)/Iowa (D694N) mutant human Abeta precursor protein in brain that accumulate abundant cerebral microvascular fibrillar amyloid deposits. In the present study, our aim was to assess how the presence or absence of fibrillar Abeta deposition in the cerebral microvasculature affects neuroinflammation in Tg-SwDI mice. Using Tg-SwDI mice bred onto an apolipoprotein E gene knock-out background, we found a strong reduction of fibrillar cerebral microvascular Abeta deposition, which was accompanied by a sharp decrease in microvascular-associated neuroinflammatory cells and interleukin-1beta levels. Quantitative immunochemical measurements showed that this reduction of the neuroinflammation occurred in the absence of lowering the levels of total Abeta40/Abeta42 or soluble Abeta oligomers in brain. These findings suggest that specifically reducing cerebral microvascular fibrillar Abeta deposition, in the absence of lowering either the total amount of Abeta or soluble Abeta oligomers in brain, may be sufficient to ameliorate microvascular amyloid-associated neuroinflammation.

Cerebral microvascular amyloid beta protein deposition induces vascular degeneration and neuroinflammation in transgenic mice expressing human vasculotropic mutant amyloid beta precursor protein. (5/15)Cerebral vascular amyloid beta-protein (Abeta) deposition, also known as cerebral amyloid angiopathy, is a common pathological feature of Alzheimer's disease. Additionally, several familial forms of cerebral amyloid angiopathy exist including the Dutch (E22Q) and Iowa (D23N) mutations of Abeta. Increasing evidence has associated cerebral microvascular amyloid deposition with neuroinflammation and dementia in these disorders. We recently established a transgenic mouse model (Tg-SwDI) that expresses human vasculotropic Dutch/Iowa mutant amyloid beta-protein precursor in brain. Tg-SwDI mice were shown to develop early-onset deposition of Abeta exhibiting high association with cerebral microvessels. Here we present quantitative temporal analysis showing robust and progressive accumulation of cerebral microvascular fibrillar Abeta accompanied by decreased cerebral vascular densities, the presence of apoptotic cerebral vascular cells, and cerebral vascular cell loss in Tg-SwDI mice. Abundant neuroinflammatory reactive astrocytes and activated microglia strongly associated with the cerebral microvascular fibrillar Abeta deposits. In addition, Tg-SwDI mouse brain exhibited elevated levels of the inflammatory cytokines interleukin-1beta and -6. Together, these studies identify the Tg-SwDI mouse as a unique model to investigate selective accumulation of cerebral microvascular amyloid and the associated neuroinflammation. (+info)
Inhibition of familial cerebral amyloid angiopathy mutant amyloid beta-protein fibril assembly by myelin basic protein. (6/15)Deposition of fibrillar amyloid beta-protein (Abeta) in the brain is a prominent pathological feature of Alzheimer disease and related disorders, including familial forms of cerebral amyloid angiopathy (CAA). Mutant forms of Abeta, including Dutch- and Iowa-type Abeta, which are responsible for familial CAA, deposit primarily as fibrillar amyloid along the cerebral vasculature and are either absent or present only as diffuse non-fibrillar plaques in the brain parenchyma. Despite the lack of parenchymal fibril formation in vivo, these CAA mutant Abeta peptides exhibit a markedly increased rate and extent of fibril formation in vitro compared with wild-type Abeta. Based on these conflicting observations, we sought to determine whether brain parenchymal factors that selectively interact with and modulate CAA mutant Abeta fibril assembly exist. Using a combination of immunoaffinity chromatography and mass spectrometry, we identified myelin basic protein (MBP) as a prominent brain parenchymal factor that preferentially binds to CAA mutant Abeta compared with wild-type Abeta. Surface plasmon resonance measurements confirmed that MBP bound more tightly to Dutch/Iowa CAA double mutant Abeta than to wild-type Abeta. Using a combination of biochemical and ultrastructural techniques, we found that MBP inhibited the fibril assembly of CAA mutant Abeta. Together, these findings suggest a possible role for MBP in regulating parenchymal fibrillar Abeta deposition in familial CAA. (+info)
Lipoprotein receptor-related protein-1 mediates amyloid-beta-mediated cell death of cerebrovascular cells. (7/15)Inefficient clearance of A beta, caused by impaired blood-brain barrier crossing into the circulation, seems to be a major cause of A beta accumulation in the brain of late-onset Alzheimer's disease patients and hereditary cerebral hemorrhage with amyloidosis Dutch type. We observed association of receptor for advanced glycation end products, CD36, and low-density lipoprotein receptor (LDLR) with cerebral amyloid angiopathy in both Alzheimer's disease and hereditary cerebral hemorrhage with amyloidosis Dutch type brains and increased low-density lipoprotein receptor-related protein-1 (LRP-1) expression by perivascular cells in cerebral amyloid angiopathy. We investigated if these A beta receptors are involved in A beta internalization and in A beta-mediated cell death of human cerebrovascular cells and astrocytes. Expression of both the LRP-1 and LDLR by human brain pericytes and leptomeningeal smooth muscle cells, but not by astrocytes, increased on incubation with A beta. Receptor-associated protein specifically inhibited A beta-mediated up-regulation of LRP-1, but not of LDLR, and receptor-associated protein also decreased A beta internalization and A beta-mediated cell death. We conclude that especially LRP-1 and, to a minor extent, LDLR are involved in A beta internalization by and A beta-mediated cell death of cerebral perivascular cells. Although perivascular cells may adapt their A beta internalization capacity to the levels of A beta present, saturated LRP-1/LDLR-mediated uptake of A beta results in degeneration of perivascular cells.

Journal Club Review: "Cerebral Amyloid Angiopathy with and without Haemorrhage | Neurology Online Journal Club
Background Sporadic cerebral amyloid angiopathy (CAA) is the most common cause of lobar intracranial haemorrhage, which in itself accounts for about 5-10% of all strokes. Amyloid deposition in small arteries of the cerebrum leads to friability and haemorrhage. There are also rare familial forms of amyloidosis affecting the nervous system that more typically result in early…
Cerebral Amyloid Angiopathy in the Aetiology of Alzheimer's disease and its effect on Therapy. - ePrints Soton
Amyloid is deposited in the walls of arteries and capillaries as cerebral amyloid angiopathy (CAA) in the brains of older individuals and of those with Alzheimer disease (AD). CAA in AD reflects an age-related failure of elimination of amyloid-beta (A?) from the brain along perivascular lymphatic drainage pathways. In the absence of conventional lymphatic vessel in the brain, interstitial fluid and solutes drain from the brain to cervical lymph nodes along narrow basement membranes in the walls of capillaries and arteries, a pathway that is largely separate from the cerebrospinal fluid. In this review we focus on the pathology and pathogenesis of CAA, its role in the aetiology of AD and its impact on immunotherapy for AD. The motive force for lymphatic drainage of the brain appears to be generated by arterial pulsations. Failure of elimination of A? along perivascular pathways coincides with a reduction in enzymic degradation of A?, reduced absorption of A? into the blood and age-related ...

p,A hemi-paralyzed 86-year-old man was diagnosed with ischemic stroke and underwent thrombolysis. Pre-thrombolysis brain magnetic resonance imaging revealed extensive strictly lobar cerebral microbleeding (CMB). Post-thrombolytic computed tomography revealed asymptomatic multiple intracerebral hemorrhaging (ICH). His age, CMB topography, and decreased cerebral spinal fluid amyloid-β 40 and 42 levels were compatible with a diagnosis of cerebral amyloid angiopathy (CAA). There is no consensus on the safety of thrombolysis for acute stroke patients with CAA. Patients with CAA might have a higher incidence of thrombolysis-related ICH than those without CAA. ,/p,. ...

age-related macular degeneration Genetics Home Reference provides information about age-related macular degeneration. hereditary cerebral amyloid angiopathy At least one mutation in the CST3 gene has been found to cause hereditary cerebral amyloid angiopathy, a condition characterized by stroke and a decline in intellectual function (dementia), which begins in mid-adulthood. The CST3 gene mutation that has been identified causes a form of hereditary cerebral amyloid angiopathy known as the Icelandic type. This mutation replaces the protein building block (amino acid) leucine with the amino acid glutamine at position 68 in the cystatin C protein (written as Leu68Gln or L68Q). This abnormal cystatin C protein is less stable and is more prone to cluster together (aggregate) than the normal protein. The aggregated protein forms clumps called amyloid deposits that accumulate in the blood vessel walls primarily in the brain, but also in blood vessels in other areas of the body such as the skin, ...
Neuroimaging Demonstration of Evolving Small Vessel Ischemic Injury in Cerebral Amyloid Angiopathy | Stroke
Cerebral amyloid angiopathy is estimated to be responsible for ≈5% to 20% of nontraumatic intracerebral hemorrhages and 30% of lobar hemorrhages.3 Whereas CAA may be asymptomatic, a classic clinical presentation is lobar hemorrhage, often recurrent or multifocal, in an elderly individual. Less commonly, patients may present with TIA or other ischemic stroke-like episodes, seizures, or dementia involving a spectrum of cognitive decline.4. In the past decade, neuroimaging studies, particularly MRI, have played an increasingly important role in the diagnosis and understanding of the pathophysiology of CAA.5 Specifically, gradient-recalled echo sequences have documented the occurrence, frequency, and distribution of microbleeds. Multiple lobar microbleeds, particularly in the absence of deep microbleeds and an alternative cause (eg, hypertension, CADASIL), are now considered a radiological hallmark of CAA.1. An additional MRI technique, diffusion-weighted imaging, has offered the ability to ...

Tissue Microstructural Changes Are Independently Associated With Cognitive Impairment in Cerebral Amyloid Angiopathy | Stroke
The major finding from this cohort study of patients with possible or probable CAA is that, among MRI markers of CAA, global mean ADC (reflecting microstructural tissue organization) is most strongly related to the presence of pre-ICH cognitive impairment. The association of mean ADC with PICI was independent of age, clinical variables, amount of visible cerebral atrophy, and other MRI markers. By contrast, we failed to detect a relationship between PICI and WMH volume, number of MB, or visible cerebral atrophy.. Decreased cognitive performance has previously been associated with CAA. The prevalence of cognitive dysfunction before CAA-related ICH is reported to be 20% to 40%4,5,17,30 Autopsy-based studies of stroke-free individuals show that CAA is a risk factor for decreased antemortem cognitive performance while simultaneously controlling for the pathology of Alzheimer disease.31,32 This suggests that the association between CAA and cognitive dysfunction is not entirely mediated by concomitant ...

Cerebral amyloid angiopathy (CAA) is characterized by the deposition of fibrillar protein with beta-pleated sheet configuration in the media and adventitia of small cortical and leptomeningeal arteries and capillaries . Previous studies based on autopsy observation revealed that the risk of CAA increased with age, which was around 38% between 80-89 years reached up to 42% in patient above the age of 90 . CAA encompasses specific cerebrovascular traits including spontaneous lobar intracerebral hemorrhage (ICH), cognitive impairment, subarachnoid hemorrhage, and transient focal neurological episodes, with characteristic imaging manifestation of lobar ICH, cortical superficial siderosis, white matter changes, microhemorrhage and microinfarct.. Interestingly in our case report, the microbleeds were strictly lateralized and predominantly in the MCA supplied territory, rather than in a diffused pattern. It has been acknowledged that the CAA could have certain localization preference. One ...
CAA is not necessarily associated with CAA-related disorders. The pathogenesis of CAA-related disorders consists of two steps: (1) cerebrovascular amyloid deposition and (2) vascular injury including disruption, occlusion, and permeability changes. The cerebrovascular amyloid deposition (Step 1) is the primary target of prevention and therapy. Anti-amyloid therapies for CAA are under development including ponezumab, a humanized monoclonal antibody that binds specifically to the carboxyl terminus of Aβ40.115 Ponezumab was originally developed for AD immunotherapy, and an acceptable safety profile has been suggested for ponezumab in clinical trials for AD.116,117,118 Currently, ponezumab has been applied to CAA. A phase 2, randomized, double-blind, placebo-controlled trial is ongoing to evaluate the safety, tolerability, pharmacokinetics, and efficacy of ponezumab (PF-04360365) in adult patients with probable CAA-related hemorrhages (NCT01821118).119.

Non-traumatic cortical superficial siderosis (cSS) is a common finding in patients with cerebral amyloid angiopathy (CAA) and can be its sole imaging sign. The clinical features and course as well as the prognostic significance of cSS in CAA patients remain unclear. In a retrospective study we have previously shown that cSS might be an important predictor or warning sign for future intracranial hemorrhage. However, prospective data are missing. The Superficial Siderosis in Patients with suspected Cerebral Amyloid Angiopathy (SuSPect-CAA) study is designed as a prospective observational multi-centre cohort study. Primary objective of the study is to evaluate if cSS is a predictor for future stroke and mortality (primary endpoint: combined rate of stroke and death after 36 months). Secondary objectives of the study include 1) to evaluate if cSS represents a marker of future intracranial haemorrhage, especially at the site of initial siderosis, 2) to describe the clinical presentation and course of ...

Blood Oxygen Level Dependant (BOLD) fMRI was performed at Screening (Baseline) and on Days 2 and 90. During each of these sessions, BOLD fMRI images were acquired in rapid succession as a flashing radial black and white checkerboard was presented alternately with a gray screen. This well established visual stimulus is known to produce a reliable increase in BOLD fMRI signal within the visual cortex region of the occipital lobe. The time course of the BOLD fMRI signal was used to assess the vascular reactivity. Imaging sites also acquired cerebral blood flow data using Arterial Spin Labeled (ASL) scans at Screening and on Days 2 and 90. A standard T1-weighted image was also acquired to aid image analysis. All efficacy scans were analyzed centrally. Geometric means are presented in the original scale and standard errors (SE) are presented in logarithmic (log e) scale ...

Azeliragon, also known as TTP488 and PF-04494700, is a potent and orally active RAGE inhibitor. RAGE (receptor for advanced glycation endproducts) is a pattern recognition receptor, which affects the movement of amyloid, an Alzheimers-associated protein, into the brain. In preclinical studies, azeliragon decreased brain amyloid in mice and improved their performance on behavior tests. Azeliragon is a promising agent for for Alzheimers disease and cerebral amyloid angiopathy.

The studies by Meyer-Luehman et al. extend insights into the in vivo formation of amyloid deposits by amyloid seeds that may be hetero- and/or homo-amyloidogenic inducers of amyloid fibrillization. This is significant because these types of studies will lead to the clarification of the perplexing conundrum of why there is a frequent co-occurrence of multiple different types of amyloids in neurodegenerative disorders characterized by brain amyloidosis. Indeed, double and triple neurodegenerative brain amyloidoses appear to far exceed in incidence and prevalence any neurodegenerative brain amyloidosis linked to a single amyloidogenic protein or peptide, and this enigma demands clarification if we are to develop more effective therapies for these disorders.. For example, with respect to Aβ deposits, these may occur by themselves as pathological signatures of single brain amyloidoses, such as cerebral amyloid angiopathy (CAA), which most commonly manifests clinically as stroke. This ...
Pathological protein deposits linked to Alzheimer's disease and cerebral amyloid angiopathy can be triggered by peripheral administration of pathogenic misfolded protein fragments outside the brain. This shows a new study done by researchers at the Hertie Institute of Clinical Brain Research and the German Center for Neurodegenerative Diseases (DZNE).

Spontaneous intracerebral hemorrhage (ICH), defined as nontraumatic bleeding into the brain parenchyma, is the second most common subtype of stroke, with 5.3 million cases and over 3 million deaths reported worldwide in 2010. Case fatality is extremely high (reaching approximately 60 % at 1 year post event). Only 20 % of patients who survive are independent within 6 months. Factors such as chronic hypertension, cerebral amyloid angiopathy, and anticoagulation are commonly associated with ICH. Chronic arterial hypertension represents the major risk factor for bleeding ...
Alzheimers disease (AD), the most common form of neurodegenerative disorder, is characterized by deposition of amyloid-β (Aβ) plaques in the brain. Aβ monomer undergoes nucleation to form oligomers, then soluble aggregates, then fibrils which make up the plaques. Aβ oligomer species are believed to be the most neurotoxic aggregate species. Currently under investigation is a mechanism for Aβ removal from the brain, across the blood-brain barrier (BBB). P-glycoprotein (P-gp) is a membrane-bound efflux protein located on the apical, or blood, side of the BBB, which transports a wide variety of substrates. Further complicating this potential clearance mechanism is the reduction of P-gp cell surface expression in arteries exhibiting cerebral amyloid angiopathy (CAA), or the buildup of amyloid plaques around the arteries. P-gp has been suggested as a potential Aβ clearance mechanism based on its ability to transport a wide variety of amphipathic substrates even though experimental evidence of Aβ

In this review, we present preliminary evidence which suggests that the extracellular-matrix-degrading protease, matrix metalloproteinase-9 (MMP-9), may play a role in the development of spontaneous ICH resulting from CAA. The amyloid-beta peptide (Aβ) induced the synthesis, cellular release, and activation of MMP-9 in murine cerebral endothelial cells (CECs), resulting in increased extracellular matrix (ECM) degradation. Furthermore, in a mouse model of CAA (APPsw transgenic mice), MMP-9 ...

In addition to directly binding to toxic beta amyloid and preventing plaque formation, curcumin has been shown to have at least seven other mechanisms that minimize the formation of beta amyloid. (These are outlined in Table 1.) All eight of these mechanisms are likely to be at work in an experiment in which specialized microscopy was used to study beta amyloid plaques in a mouse model of Alzheimers. This study demonstrated that curcumin enters the brain and then binds specifically to plaques, reducing their size by up to 30%.9 ...
The article by Pfeifer et al. describes the exacerbation of cerebral hemorrhages seen in an aged APP-transgenic model following passive administration of anti-Aβ antibodies directed to amino acids 3-6. This particular transgenic mouse, called APP23, is described by the authors in a previous paper as a spontaneous hemorrhagic stroke mouse model (Winkler et al., 2001). At approximately 19 months of age onward, the mouse exhibits severe cerebral amyloid angiopathy (CAA), which is associated with recurrent hemorrhages as the mice age. Moderate to severe cerebral vascular amyloid also exists in approximately 26 percent of Alzheimers disease patients, as well, though the rate of hemorrhages is less than that seen in the APP23 mouse (approximately five percent of AD cases; see Greenberg et al., 1998).. When the authors gave 21-month-old APP23 mice a monoclonal antibody directed to Aβ3-6 once a week for five months, they saw that the rate of hemorrhages increased about twofold above baseline.

"Blocking the apolipoprotein E/Amyloid-Beta interaction reduces fibrill" by Jin Yang, Yong Ji et al.
The accumulation of amyloid-β (Aβ) peptides as toxic oligomers, amyloid plaques, and cerebral amyloid angiopathy (CAA) is critical in the pathogenesis of Alzheimers disease (AD). The binding of Aβ peptides to apolipoprotein E (ApoE) plays an important role in modulation of amyloid deposition and clearance. We have shown that blocking the Aβ/ApoE interaction with Aβ12-28P, a nontoxic blood-brain-barrier permeable and non-fibrillogenic synthetic peptide, constitutes a novel therapeutic approach for AD by reducing Aβ parenchymal deposition. In the present study, we investigate this therapeutic effect on CAA in the transgenic (Tg) AD mice model (TgSwDI), which expresses Swedish (K670N/M671L), Dutch (E693Q)/Iowa (D694N) Aβ PP mutations. These mice develop abundant CAA beginning at the age of 6 months. Behavioral results show that Aβ12-28P treated TgSwDI AD mice performed the same as wild-type mice, whereas vehicle treated TgSwDI were impaired in spatial memory. Furthermore, this treatment resulted
The location of a primary intracerebral hemorrhage (ICH) plays a large role in identifying the underlying cause and prognosis.1 Deep ICHs, located in the basal ganglia or brainstem, are associated with arteriolosclerosis due to aging, hypertension, and other conventional vascular risk factors, and they have a low rate of recurrence (≈1%/y-2%/y) if blood pressure is well controlled. Lobar ICHs, located in the cortex or underlying white matter, may instead be associated with cerebral amyloid angiopathy (CAA) caused by vascular amyloid deposition and are associated with several-fold higher risk of recurrence. MRI can further risk-stratify patients by identifying microbleeds or cortical superficial siderosis, indicating past asymptomatic bleeding events.1 In patients with lobar ICH, evidence of superficial siderosis or microbleeds restricted exclusively to lobar locations increases the probability that the underlying cause is CAA,2 and they are associated with a high risk for recurrence. ...
Several studies have shown that elevated plasma cholesterol levels (i.e. hypercholesterolemia) serve as a risk factor for late-onset Alzheimers disease (AD). However, it remains unclear how hypercholesterolemia may contribute to the onset and progression of AD pathology. In order to determine the role of hypercholesterolemia at various stages of AD, we evaluated the effects of high cholesterol diet (5% cholesterol) in wild-type (WT; C57BL6) and triple-transgenic AD (3xTg-AD: Psen1, APPSwe, tauB301L) mice at 7, 14, and 20 months. The transgenic APP-Swedish/Dutch/Iowa AD mouse model (APPSwDI) was used as a control since these animals are more pathologically-accelerated and are known to exhibit extensive plaque deposition and cerebral amyloid angiopathy. Here, we describe the effects of high cholesterol diet on: (1) cognitive function and stress, (2) AD-associated pathologies, (3) neuroinflammation, (4) blood-brain barrier disruption and ventricle size, and (5) vascular dysfunction. Our data show ...
Researchers find pathologic hallmarks of Alzheimer's disease in aged chimpanzee brains - Scienmag: Latest Science and Health...
Tau lesions also were found in the forms of NFT and clusters of tau-positive neurites (for example, pieces of dying neurons). NFT are observed in AD patients, but the tau-immunoreactive neuritic clusters in the neocortex appear specific to chimpanzees, said Dr. Patrick R. Hof, M.D., the Regenstreif professor and vice-chair of neuroscience at Icahn School of Medicine at Mount Sinai. In addition, NFT pathology was observed in apes that exhibited plaques and moderate or severe cerebral amyloid angiopathy and in one individual with virtually no Aβ pathology.. The presence of amyloid and tau pathology in aged chimpanzees indicates these AD lesions are not specific to the human brain as generally believed, Hof said. Whether these pathologies play a key role in age-related cognitive decline requires continued investigation of this species, said Dr. Elliott Mufson, professor and the Greening Chair in Aging at the Barrow Neurological Institute.. This research adds to a growing number of studies ...
Monogenic diseases associated with intestinal inflammation: implications for the understanding of inflammatory bowel disease. -...
Inflammatory bowel disease (IBD), encompassing Crohns disease and ulcerative colitis, has multifactorial aetiology with complex interactions between genetic and environmental factors. Over 150 genetic loci are associated with IBD. The genetic contribution of the majority of those loci towards explained heritability is low. Recent studies have reported an increasing spectrum of human monogenic diseases that can present with IBD-like intestinal inflammation. A substantial proportion of patients with those genetic defects present with very early onset of intestinal inflammation. The 40 monogenic defects with IBD-like pathology selected in this review can be grouped into defects in intestinal epithelial barrier and stress response, immunodeficiencies affecting granulocyte and phagocyte activity, hyper- and autoinflammatory disorders as well as defects with disturbed T and B lymphocyte selection and activation. In addition, there are defects in immune regulation affecting regulatory T cell activity and

Vascular response to acetazolamide decreases as a function of age in the arcA beta mouse model of cerebral amyloidosis -...
Deposition of beta-amyloid along cerebral vessels is found in most patients suffering from Alzheimers disease. The effects of cerebral amyloid angiopathy (CAA) on the function of cerebral blood vessels were analyzed applying cerebral blood volume (CBV)-based fMRI to transgenic arcA beta mice. In a cortical brain region of interest (ROI), displaying high CAA, arcA beta mice older than 16 months showed reduced response to the vasodilatory substance acetazolamide compared to age-matched wild-type animals, both with regard to rate (vascular reactivity) and extent of vasodilation (maximal vasodilation). In a subcortical ROI, displaying little CAA, no genotype-specific decrease was observed, but maximal vasodilation decreased with age in arcA beta and wild-types. These findings indicate that vascular beta-amyloid deposits reduce the capacity of cerebral blood vessels to dilate upon demand, supporting the hypothesis that vascular beta-amyloid contributes to hypoperfusion and neurological deficits ...
Cerebrospinal Fluid Alzheimer's Disease Biomarkers in Isolated Supratentorial Cortical Superficial Siderosis. - Semantic Scholar
We evaluated cerebrospinal fluid amyloid-β 1-40 (Aβ40), amyloid-β 1-42 (Aβ42), total and phosphorylated-tau (t-tau and p-tau) in patients with symptomatic isolated cortical supratentorial superficial siderosis (SS), by prospectively recruiting ten patients with SS in the absence of pre-existing cognitive dysfunction, and comparing biomarkers with lobar hematoma cerebral amyloid angiopathy patients (LH-CAA, n = 13), Alzheimers disease patients (AD, n = 42), and controls (n = 16). Compared to controls, SS patients showed statistically significant higher t-tau (p = 0.019) and lower Aβ42 (p = 0.0084). Compared to other groups, SS showed statistically significant lower t-tau, p-tau, and Aβ40 compared to AD (p = 0.0063, p = 0.0004, and p = 0022, respectively), and higher p-tau compared to LH-CAA (p = 0.012).
Cerebral amyloid angiopathy-related inflammation presenting with steroid-responsive higher brain dysfunction: case report and...
A 56-year-old man noticed discomfort in his left lower limb, followed by convulsion and numbness in the same area. Magnetic resonance imaging (MRI) showed white matter lesions in the right parietal lobe accompanied by leptomeningeal or leptomeningeal and cortical post-contrast enhancement along the parietal sulci. The patient also exhibited higher brain dysfunction corresponding with the lesions on MRI. Histological pathology disclosed β-amyloid in the blood vessels and perivascular inflammation, which highlights the diagnosis of cerebral amyloid angiopathy (CAA)-related inflammation. Pulse steroid therapy was so effective that clinical and radiological findings immediately improved. CAA-related inflammation is a rare disease, defined by the deposition of amyloid proteins within the leptomeningeal and cortical arteries associated with vasculitis or perivasculitis. Here we report a patient with CAA-related inflammation who showed higher brain dysfunction that improved with steroid therapy. In cases with
Neuronal overexpression of mutant amyloid precursor protein results in prominent deposition of cerebrovascular amyloid | PNAS
As has been described in naturally occurring CAA (1, 5), vascular amyloid deposition in APP23 mice is most frequently found in arteries/arterioles and occurs most often in vessels outside the brain parenchyma proper (e.g., pia, fissures). The arterial predilection suggests that an anatomical difference between arteries and veins (e.g., presence of significant amounts of smooth muscle) could contribute to the development of CAA. Indeed, it has been hypothesized that Aβ is deposited by vascular smooth muscle cells and/or perivascular microglia, and APP expression and Aβ production by vascular cells have been well documented (22, 23). These reports and the observation that vessels apart from the neuropil are more often affected strongly implicate local production or circulating Aβ as an important source, although these hypotheses fail to explain the exclusive localization of CAA to cerebral vessels. In the present study, through examination of APP transgenic mice on an App-null background, we ...
Lack of Neurodegeneration in Transgenic Mice Overexpressing Mutant Amyloid Precursor Protein Is Associated with Increased...
We have shown that the expression of a number of protective genes and a protective pathway culminating in Bad phosphorylation are increased in mice that overexpress APPSw and have no neuronal loss. Increased levels of IGF-2 mRNA and protein correspond to increased activation of the IGF-1 receptor, activation of Akt and Erk1/2, and phosphorylation of Bad in APPSw mice. The increased expression of TTR and IGF-2 as well as increased phospho-Bad staining in hippocampal neurons was consistent in both preplaque (6 months) and postplaque (12 months) Tg2576 mice. Other conditions, such as the presence of a human tau gene, may be necessary for complete AD pathology. However, taken together, these data imply that the lack of neurodegeneration in APPSw mice is a result of the activation of known cell survival pathways associated with the overexpression of APPSw.. Transthyretin has been shown to bind Aβ and inhibit Aβ aggregation (Schwarzman et al., 1994). In human AD patients the concentration of TTR is ...
