eIF2α controls memory consolidation via excitatory and somatostatin neurons

open access: yes, 2020
An important tenet of learning and memory is the notion of a molecular switch that promotes the formation of long-term memory1,2,3,4. The regulation of proteostasis is a critical and rate-limiting step in the consolidation of new memories5,6,7,8,9,10 ...

Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

PfeIK1, a eukaryotic initiation factor 2α kinase of the human malaria parasite Plasmodium falciparum, regulates stress-response to amino-acid starvation

open access: yesMalaria Journal, 2009
Background Post-transcriptional control of gene expression is suspected to play an important role in malaria parasites. In yeast and metazoans, part of the stress response is mediated through phosphorylation of eukaryotic translation initiation factor 2α

Bisphenol Analog‐Induced Cytotoxicity: Unraveling Endoplasmic Reticulum (ER) Stress and Apoptotic Pathways

open access: yesJournal of Applied Toxicology, Volume 46, Issue 12, Page 4782-4798, December 2026.
ABSTRACT Bisphenol A (BPA) is increasingly replaced by structural analogs, yet their safety remains insufficiently characterized. This study investigated whether BPA and selected analogs, bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP), and bisphenol E (BPE), induce cytotoxicity through activation of endoplasmic reticulum (ER) stress and ...

Mammalian Orthoreovirus Escape from Host Translational Shutoff Correlates with Stress Granule Disruption and Is Independent of eIF2α Phosphorylation and PKR

open access: yes, 2011
In response to mammalian orthoreovirus (MRV) infection, cells initiate a stress response that includes eIF2α phosphorylation and protein synthesis inhibition.

Shikonin: From Biosynthesis and Pharmacological Mechanisms to Translational Safety and Drug Delivery

open access: yesChemBioChem, Volume 27, Issue 21, 12 November 2026.
Shikonin, biosynthesised in Boraginaceae roots from phenylalanine‐derived PHB and isoprenoid GPP, modulates redox balance, cellular stress, signalling pathways, and regulated cell death. Preclinical studies support diverse pharmacological activities, while nanocarriers improve dispersion and delivery.

Chemical Bond‐Orchestrated Energy Depletion to Augment Lung Cancer Chemo‐Immunotherapy

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
This study grafted dichloroacetic acid (DCA) into perylenediimide (PDI) skeleton via ionic or covalent bond to create novel metabolic agent PDIC‐AC and PDIC‐NAC, explicitly elaborated the underlying energy metabolism and therapeutic mechanism, and developed a promising strategy for energy metabolism‐targeting chemo‐immunotherapy by chemical bond ...

Research Trends and Mechanistic Insights Into Natural Medicines for Alzheimer's Disease: A Bibliometric Analysis and Narrative Review

open access: yesPhytotherapy Research, Volume 40, Issue 11, Page 6490-6515, November 2026.
Research landscape and mechanistic insights into natural medicines for Alzheimer's disease. ABSTRACT Natural medicines have been widely investigated for Alzheimer's disease (AD), but the development of this field and the relationship between bibliometric themes and experimental evidence remain insufficiently characterized.

eIF2α signaling regulates autophagy of osteoblasts and the development of osteoclasts in OVX mice [PDF]

open access: yes, 2019
Bone loss in postmenopausal osteoporosis is induced chiefly by an imbalance of bone-forming osteoblasts and bone-resorbing osteoclasts. Salubrinal is a synthetic compound that inhibits de-phosphorylation of eukaryotic translation initiation factor 2 ...

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

open access: yesPhytotherapy Research, Volume 40, Issue 11, Page 6535-6552, November 2026.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.
