Village guards as “in between” in the Turkish-Kurdish conflict: Re-examining identity and position in intergroup conflict [PDF]
The current paper utilizes new approaches in intergroup conflict studies to examine the village guard system and its role in the Turkish-Kurdish conflict in Turkey.

Presenilin/γ-secretase and inflammation
Presenilins (PS) are the catalytic components of γ-secretase, an aspartyl protease that regulates through proteolytic processing the function of multiple signaling proteins.

Signal peptide peptidases and gamma-secretase: Cousins of the same protease family? [PDF]
Signal peptide peptidase (SPIP) is an unusual aspartyl protease, which mediates clearance of signal peptides by proteolysis within the endoplasmic reticulum (ER).

Inactivation of presenilins causes pre-synaptic impairment prior to post-synaptic dysfunction [PDF]
Synaptic dysfunction is widely thought to be a pathogenic precursor to neurodegeneration in Alzheimer’s disease (AD), and the extent of synaptic loss provides the best correlate for the severity of dementia in AD patients.

Presenilin-1 and Presenilin-2 Exhibit Distinct yet Overlapping γ-Secretase Activities [PDF]
Presenilin-1 (PS1) and presenilin 2 (PS2) are proposed to be transmembrane aspartyl proteases that cleave amyloid precursor protein and Notch. PS1- and PS2-mediated activities were individually characterized using blastocyst-derived (BD) cells and membranes from PS1+/--PS2-/- and PS1-/-PS2+/+ mice, respectively.

A common feature in the Alzheimer’s disease (AD) brain is the presence of acetylcholinesterase (AChE) which is commonly associated with β-amyloid plaques and neurofibrillary tangles.

Specificity of presenilin‐1‐ and presenilin‐2‐dependent γ‐secretases towards substrate processing [PDF]
AbstractThe two presenilin‐1 (PS1) and presenilin‐2 (PS2) homologs are the catalytic core of the γ‐secretase complex, which has a major role in cell fate decision and Alzheimer's disease (AD) progression. Understanding the precise contribution of PS1‐ and PS2‐dependent γ‐secretases to the production of β‐amyloid peptide (Aβ) from amyloid precursor ...

A role for presenilin in post-stress regulation: effects of presenilin mutations on Ca2+ currents in Drosophila [PDF]
It has been shown that presenilin is involved in maintaining Ca(2+) homeostasis in neurons, including regulating (ER) Ca(2+) storage. From studies of primary cultures and cell lines, however, its role in stress-induced responses is still controversial ...

Background Mutations of three causative genes, namely presenilin 1 (PSEN1), presenilin 2 (PSEN2), and amyloid precursor protein (APP), have been identified as the major causes of early‐onset familial Alzheimer's disease (EOFAD).
