Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

Imaging Alzheimer's genetic risk using diffusion MRI: A systematic review

NeuroImage: Clinical, 2020
Diffusion magnetic resonance imaging (dMRI) is an imaging technique which probes the random motion of water molecules in tissues and has been widely applied to investigate changes in white matter microstructure in Alzheimer’s Disease.

Altered expression of Alzheimer's disease-related proteins in male hypogonadal mice [PDF]

, 2012
Age-related depletion of estrogens and androgens is associated with an increase in Alzheimer's disease (AD) brain pathology and diminished cognitive function. Here we investigated AD-associated molecular and cellular changes in brains of aged hypogonadal

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

FEBS Open Bio, Volume 16, Issue 5, Page 885-905, May 2026.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Treatment of Alzheimer's Disease with Anti-Homocysteic acid Antibody [PDF]

, 2008
Homocysteic acid (HA) may play an important role in Alzhiemer disease (AD) as we previously reported that HA induced accumulation of intraneuronal A[beta]42. In this study, we first analyzed HA levels in a mouse model of AD.

GPND‐AI NULISA: A 15‐Protein AI classifier for diagnosis and co‐pathology profiling across neurodegenerative diseases

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Accurate clinical diagnosis of neurodegenerative diseases remains challenging, particularly when individuals have mixed pathologies. We implemented the generalizable protein‐based neurodegenerative disease artificial intelligence (GPND‐AI) classifier using the NUcleic acid‐Linked Immuno‐Sandwich Assay (NULISA) central nervous ...

Presenilin 2 influences miR146 level and activity in microglia. [PDF]

J Neurochem, 2013
AbstractMicroglia, the resident innate immune cells of the CNS, are the primary defenders against microbes and critical to CNS remodeling. Dysregulation of microglial behavior can lead to unchecked pro‐inflammatory activity and subsequent neurodegeneration.

rTCT: Rodent Triangle Completion Task to Facilitate Reverse Translational Study of Path Integration

Hippocampus, Volume 36, Issue 3, May 2026.
ABSTRACT Path integration is navigation in the absence of environmental landmarks and is a primary cognitive mechanism underlying spatial memory. Path integration performance is primarily assessed in humans using the Triangle Completion Task (TCT). In humans, TCT has shown promise for the early diagnosis of Alzheimer's disease.

Exogenous Aβ1–42 monomers rescue memory deficits in presenilin-1 and presenilin-2 conditional double knockout mice

Brain Research Bulletin
Emerging evidence challenges the direct causal relationship between amyloid-β (Aβ) deposition and cognitive decline in Alzheimer's disease (AD), as exemplified in presenilin-1 and presenilin-2 conditional double knockout (cDKO) mice which exhibit no ...

Quality control of protein import into mammalian mitochondria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Mitochondrial function depends on the continuous import of hundreds of nuclear‐encoded proteins. Targeting and translocation of mitochondrial proteins is a multistep process that is inherently vulnerable to defects in cytosolic quality control systems as well as perturbations in mitochondrial protein import machinery and organelle function ...
