Abi3S212F Alzheimer's disease variant alters plaque structure and disrupts microglia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract BACKGROUND Genetic variants affecting microglial function can influence Alzheimer's disease (AD) risk, yet the underlying mechanisms remain unclear. The AD‐associated ABI3S209F (Abi3S212F in mouse) variant regulates cytoskeletal dynamics, but its in vivo impact on pathology is unknown. METHODS: An Abi3S212F mouse was developed and crossed with

Multipliers of von neumann regular rings

Communications in Algebra, 2000
We analyse the structure of the multiplier ring M(R) of a(nonuni-tal)Von Neumann regular ring R. We show that M(R) is not regular in general, but every principal right ideal is generated by two idempotents. This, together with Riesz Decomposition on idempotents of M(R), furnishes a description of the monoid V(M(R)) of Murray-Von Neumann equivalence ...

Combining Local and Von Neumann Regular Rings

Communications in Algebra, 2004
All rings R considered are commutative and have an identity element. Contessa called R a VNL-ring if a or 1 − a has a Von Neumann inverse whenever a ∈ R.

Von Neumann Regular Rings Satisfying Weak Comparability

Applied Categorical Structures, 2007
For modules \(X\) and \(Y\) over a ring \(R\), write \(X\lesssim Y\) (resp. \(X\prec Y\)) in case \(X\) is isomorphic to a submodule (resp. proper submodule) of \(Y\). A regular ring \(R\) `satisfies weak comparability' if for each nonzero \(x\in R\) there is a positive integer \(n=n(x)\) such that \(n(yR)\lesssim R\) implies \(yR\lesssim xR\) for all \

Larders from Von Neumann Regular Rings

2011
The assignment that sends a regular ring R to its lattice of all principal right ideals can be naturally extended to a functor, denoted by L (cf. Sect. 1.1.2). An earlier occurrence of a condensate-like construction is provided by the proof in Wehrung (J. Math. Log. 6(1):1–24, 2006, Theo- rem 9.3).
