Altered brain energetics induces mitochondrial fission arrest in Alzheimer's Disease. [PDF]

, 2016
Altered brain metabolism is associated with progression of Alzheimer's Disease (AD). Mitochondria respond to bioenergetic changes by continuous fission and fusion.

Mitochondrial Homeostasis in Pancreatic β Cell Function: Mechanisms and Therapeutic Targets for Diabetes

Journal of Diabetes, Volume 18, Issue 5, May 2026.
This review highlights mitochondrial dysfunction as a central driver of pancreatic β cell failure in diabetes, caused by disrupted mitochondrial quality control (MQC), oxidative stress, and impaired organelle communication. Emerging therapies, such as DRAK2 inhibitors and metabolic reprogramming agents, show promise in restoring β cell function by ...

PF-06447475 Molecule Attenuates the Neuropathology of Familial Alzheimer’s and Coexistent Parkinson’s Disease Markers in PSEN1 I416T Dopaminergic-like Neurons

Molecules
Familial Alzheimer’s disease (FAD) is a complex multifactorial disorder clinically characterized by cognitive impairment and memory loss. Pathologically, FAD is characterized by intracellular accumulation of the protein fragment Aβ42 (iAβ ...

Making the final cut: pathogenic amyloid-β peptide generation by γ-secretase

Cell Stress, 2018
Alzheimer´s disease (AD) is a devastating neurodegenerative disease of the elderly population. Genetic evidence strongly suggests that aberrant generation and/or clearance of the neurotoxic amyloid-β peptide (Aβ) is triggering the disease.

SORBS2: A Molecular Nexus in Multisystem Diseases Through Scaffold‐Mediated Regulation

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Sorbin and SH3 Domain Containing 2 (SORBS2), a multifunctional scaffold protein harbouring Sorbin homology (SoHo) and Src homology 3 (SH3) domains, serves as a molecular hub in human diseases by integrating cytoskeletal remodelling, signal transduction and RNA metabolic regulation. This study systematically analyses SORBS2's molecular features,

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, Volume 16, Issue 4, Page 803-813, April 2026.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Neurodegeneration: Potential Causes, Prevention, and Future Treatment Options [PDF]

, 2011
Here I advance a hypothesis that neurodegeneration is a natural process associated with aging due to the loss of genetic redundancy following a mathematical model R(t) = R0(1-αe(βC+γI+δEt)t), where the calorie intake (C) and ...

Subcellular Mechanisms of Presenilin-Mediated Enhancement of Calcium Signaling

Neurobiology of Disease, 2001
Mutations in presenilin-1 (PS1), the leading cause of early-onset, autosomal-dominant familial Alzheimer's disease (FAD), enhance calcium signaling mediated by inositol 1,4,5-trisphosphate (IP3).

Assembly, trafficking and function of gamma-secretase [PDF]

, 2006
gamma-Secretase catalyzes the final cleavage of the beta-amyloid precursor protein to generate amyloid-beta peptide, the principal component of amyloid plaques in the brains of patients suffering from Alzheimer's disease.

Toward the structure of presenilin/γ-secretase and presenilin homologs

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2013
Presenilin is the catalytic component of the γ-secretase complex, a membrane-embedded aspartyl protease that plays a central role in biology and in the pathogenesis of Alzheimer's disease. Upon assembly with its three protein cofactors (nicastrin, Aph-1 and Pen-2), presenilin undergoes autoproteolysis into two subunits, each of which contributes one of
