Finally, similarly as the cotton wool plaques in AD resulting from exon 9 deletion in the presenilin-1 gene, the Arctic plaques induced only modest glial and inflammatory tissue reaction.

Most of the "functional" mutations for ER Ca2+ leak were clustered in the exon 8-9 area of PSEN1 gene and segregated with the cotton wool plaques and spastic paraparesis clinical phenotype occasionally observed in PS1 FAD patients.

The PSEN1 AD mutations giving rise to CWP produce unusually high levels of the amyloid beta peptide (Abeta) ending at position 42 or 43, and the main component of CWP is amino-terminally truncated forms of amyloid beta peptide starting after the alternative beta-secretase cleavage site at position 11.

Although beta-amyloid (Abeta) plaques in brain tissue are characteristic of AD patients, space occupying "cotton-wool" plaques (CWPs) lacking dense Abeta cores have also been described in patients with mutations in exon 9 of the PS-1 gene.

Our results indicate that amino-terminally truncated Abeta peptide species ending at residues 42 and 43 are the main Abeta peptides deposited in brain parenchyma and LMD-CWPs in association with the PSEN1 V261I mutation.

We considered that the mutant PSEN1 might play an important role in the pathogenetic process of both aggregation of alpha-synuclein into Lewy bodies and deposition of beta-amyloid into cotton wool plaques.

In conclusion, (1) a frontal lobe syndrome-like personality change may be one of the characteristic clinical features of early-onset CWP-AD, (2) the deposition pattern of Abeta40 and Abeta42 in CWP-AD is more variable than that of presenilin-1-linked cases, (3) Abeta deposition can result in development of dementia without tau pathology, and (4) CWP-AD with LBs and several other neurodegenerative disorders with LBs share a common process involving alpha-synuclein and NAC deposition.
