M1 muscarinic receptors (M1 mAChRs) play a role in an apparent linkage of three major hallmarks of Alzheimer's disease (AD): beta-amyloid (Abeta) peptide; tau hyperphosphorylation and paired helical filaments (PHFs); and loss of cholinergic function conducive to cognitive impairments.
|
10 |
14501019
|
Activation of M1 mAChRs with these agonists leads, inter alia, to enhanced secretion of amyloid precursor protein (alpha-APP), (via alpha-secretase activation), to decreased Abeta (via gamma-secretase inhibition), and to inhibition of Abeta- and/or oxidative stress-induced cell death.
|
11 |
14501019
|
Studies from other labs showed that AF102B and talsaclidine (another M1 agonist) decreased cerbrospinal fluid (CSF) Abeta in AD patients following chronic treatment, being the first reported drugs with such a profile.
|
12 |
14501019
|
Remarkably, although M1 agonists can decrease CSF Abeta in AD patients, an increased AD-type pathology in Parkinson's disease was recently been associated with chronic antimuscarinic treatment.
|
13 |
14501019
|
This may place such drugs in the first line of modern AD therapies (e.g., beta- or gamma-secretase inhibitors, vaccines against Abeta, statins, and inhibitors of tau hyperphosphorylation).

Neuropathological examination in that patient showed meningoencephalitis, and focal atypically low numbers of diffuse and neuritic plaques but not of vascular amyloid, nor regression of tau pathology in neurofibrillary tangles and neuropil threads.
|
21 |
14997933
|
The present neuropathological study reports the second case of meningoencephalitis following immunization with amyloid-beta peptide in AD, and has been directed toward exploring mechanisms underlying decreased tau pathology in relation with amyloid deposit regression, and possible molecular bases involved in the inflammatory response following immunization.

Inflammatory infiltrates were composed of CD8+, CD4+, CD3+, CD5+ and, rarely, CD7+ lymphocytes, whereas B lymphocytes and T cytotoxic cells CD16, CD57, TIA and graenzyme were negative.

|
Reduced amyloid burden was accompanied by low amyloid-associated oxidative stress responses (reduced superoxide dismutase-1: SOD-1 expression) and by local inhibition of the stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) and p38 kinase which are involved in tau phosphorylation.
|

These results support the amyloid cascade of tau phosphorylation in AD regarding phosphorylation of tau dependent on beta-amyloid deposition in neuritic plaques, but not of tau in neurofibrillary tangles and threads.
|

Furthermore, amyloid reduction was accompanied by increased expression of the PA28a/beta inductor, and of LMP7, LMP2 and MECL1 subunits of the immunoproteasome in microglial and inflammatory cells surrounding collapsed plaques, and in multinucleated giant cells.

The report by Oddo and colleagues in this issue of Neuron demonstrates for the first time that clearance of amyloid also results in the removal of early-stage tau pathology in mice that develop both amyloid plaques and neurofibrillary tangles (NFT), the two hallmark lesions of Alzheimer's disease (AD).

|
51 |

|
Using a triple transgenic model (3xTg-AD) that develops both lesions in AD-relevant brain regions, we determined the consequence of Abeta clearance on the development of tau pathology.
|
52 |
15294141
|
Here we show that Abeta immunotherapy reduces not only extracellular Abeta plaques but also intracellular Abeta accumulation and most notably leads to the clearance of early tau pathology.
|
53 |
15294141
|
We find that Abeta deposits are cleared first and subsequently reemerge prior to the tau pathology, indicative of a hierarchical and direct relationship between Abeta and tau.
|
54 |
15294141
|
The clearance of the tau pathology is mediated by the proteasome and is dependent on the phosphorylation state of tau, as hyperphosphorylated tau aggregates are unaffected by the Abeta antibody treatment.

The identification of disease-causing mutations in proteins such as amyloid-beta precursor protein (betaAPP) and presenilin1 (PS1), together with the discovery of other high risk factors (e.g., Apolipoprotein E4), as well as pathogenic mutations in the tau protein has led to the creation of several transgenic mice, including those expressing bi- and tri-genic constructs.
|
68 |
16972884
|
Interestingly, LAMP-1 immunoreactivity has little correlation with phosphorylated tau deposition and neurofibrillary tangles (NFTs), as neurones with NFTs were rarely LAMP-1 immunoreactive.
|
69 |
16972884
|
Finally, LAMP-1 occurred in microglia and multinucleated giant cells in one AD case in whom amyloid burden was cleared following betaA-peptide immunization.

|
An improved understanding of the pathogeneses of AD has now led to the identification of numerous therapeutic targets designed to alter amyloid beta protein (Abeta) or tau accumulation.
|
71 |
17076654
|
Therapies that alter Abeta and tau through these various targets are likely to have significant disease modifying effects.
|
72 |
17076654
|
Many of these targets have been validated in proof of concept studies in preclinical animal models, and some potentially disease modifying therapies targeting Abeta or tau are being tested in the clinic.

There was resolution of tau-containing dystrophic neurites, although other features of tau pathology (tangles and neuropil threads) remained and cerebral amyloid angiopathy persisted.

However, if it is to be used for treatment of established Alzheimer disease, then the residual tau pathology and cerebral amyloid angiopathy require further study.

The lack of progress in mechanistic approaches (the amyloid and tau hypotheses) to developing new AD drugs indicates that some of the basic assumptions of AD causality and the search for effective drugs are probably in need of major reassessment and redirection.

Due to limitations in available animal models, however, it has been unclear whether targeting amyloid is sufficient to reduce the other pathological hallmarks of AD-namely, accumulation of pathological, nonmutated tau and neuronal loss.

The oligomeric forms of Abeta are thought to be the most toxic, while fibrillar Abeta becomes deposited as amyloid plaques and congophilic angiopathy, which both serve as neuropathological markers of the disease.
|
117 |

|
Perhaps the most exciting of the therapeutic approaches being developed is immunomodulation targeting the aggregating proteins, Abeta and tau.

The amyloid cascade hypothesis of Alzheimer's disease (AD) is testable: it implies that interference with Abeta aggregation and plaque formation may be therapeutically useful.
|
120 |
20632020
|
Abeta42 immunisation of amyloid precursor protein (APP) transgenic mice prevented plaque formation and caused removal of existing plaques.
|
121 |
20632020
|
In immunised AD patients, we found: a lower Abeta load, with evidence that plaques had been removed; a reduced tau load in neuronal processes, but not in cell bodies; and no evidence of a beneficial effect on synapses.
|
122 |
20632020
|
There were pathological "side effects" including: increased microglial activation; increased cerebral amyloid angiopathy; and there is some evidence for increased soluble/oligomeric Abeta.

In the early 1980s, the NFTs were characterized, and cerebral amyloid was purified; further the amino acid sequences of the tau protein in the NFTs and of Abeta were identified.
|
124 |
20675870
|
Immunohistochemical studies with antibodies to tau and Abeta revealed that extracellular accumulation of Abeta precedes that of tau in neurons.
|
125 |
20675870
|
On the basis of these findings, the amyloid cascade hypothesis that Abeta accumulation is the primary cause of neuronal degeneration and induces accumulation of tau in the AD brain was proposed and widely accepted.
|
126 |
20675870
|
Thus, on the basis of this hypothesis, transgenic AD mice were treated with Abeta vaccine; the Abeta amyloid plaques were eliminated, and a dramatic improvement of the behavioral deficits was observed in the treated mice.

|
Further in-depth investigation and comprehensive analysis of alterations in the metabolism of APP, β-amyloid, and tau protein, which have a pathological effect on cell membrane, alter phosphate exchange, and impair other key metabolic functions of the cell long before the characteristic amyloid deposition takes place, is warranted.

|
The Alzheimer's disease (AD) process is understood to involve the accumulation of amyloid plaques and tau tangles in the brain.
|
140 |
23725605
|
AD pathogenesis has been associated with the accumulation, aggregation, and deposition of amyloid beta (Abeta) peptides in the brain.
|
141 |
23725605
|
Hallmarks of AD are the amyloid plaques consisting of fibrillar Abeta and neurofibrillary tangles which are intracellular fibrils of hyperphosphorylated tau protein that develop later in this disease.
|
142 |
23725605
|
The amyloid cascade hypothesis postulates that Abeta deposition is an initial event in the multifactorial pathogenesis and Abeta deposition may precede AD symptoms in some patients by at least 20 years.
|

Here, we briefly review the pathogenic role of amyloid and tau in AD, as well as immunotherapeutic efforts to date.

It proposes that abnormal production of beta amyloid protein (Abeta) is the cause of AD and that the neurotoxicity is due to Abeta itself or its oligomeric forms.
|
145 |
24052108
|
AD probably results from the inflammatory response induced by extracellular Abeta deposits, which later become enhanced by aggregates of tau.
|
146 |
24052108
|
Phase one can be identified by decreases in Abeta in the CSF, phase 2 by increases of tau in the CSF plus clear evidence of Abeta brain deposits by PET scanning, phase 3 by slight decreases in brain metabolic rate by PET-FDG scanning, phase 4 by slight decreases in brain volume by MRI scanning plus minimal cognitive impairment, phase 5 by increased scanning abnormalities plus clinical diagnosis of AD, and phase 6 by advanced AD requiring institutional care.

Importantly, amyloid deposition is not strongly correlated with cognition in multivariate analyses, unlike hyperphosphorylated tau, neurofibrillary tangles, and synaptic and neuronal loss, which are closely associated with memory deficits.

Alzheimer disease (AD) process involves the accumulation of amyloid plaques and tau tangles in the brain, nevertheless the attempts at targeting the main culprits, neurotoxic β-amyloid (Aβ) peptides, have thus far proven unsuccessful for improving cognitive function.

In AD, Pin1 affects two proteins thought to be key to disease pathology: the amyloid precursor protein (APP) and the microtubule-binding protein tau, by switching them from a dysfunctional shape (cis) back to a functional one (trans), which can be distinguished by cis and trans-specific antibodies.
|
153 |
24534472
|
In the brains of people with AD, Pin1 is absent or inactivated and cis tau is accumulated at early stages of AD.
|
154 |
24534472
|
In the absence of Pin1, APP is processed into toxic beta-amyloid and tau becomes misshapen to form tangles.

|
In AD, associations of spongiosis status, curvature ratio and pPKR load with microglial markers Iba1, CD68 and CD32 suggest a role for microglia in neurodegeneration.
|
165 |
25430817
|
After immunization, correlations were detected between the number of NeuN-positive neurons and pPKR with Iba1, CD68 and CD64, suggesting that microglia are involved in the neuronal loss.
