Flow Cytometry Characterization and Analysis of Glial and Immune Cells from the Spinal Cord

Neuroglia
Several protocols have been developed with the aim of characterizing glial and immune cells from the central and peripheral nervous systems. However, a small number of these protocols have demonstrated the ability to yield satisfactory results following ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Multilineage Potential and Self-Renewal Define an Epithelial Progenitor Cell Population in the Adult Thymus

Cell Reports, 2014
Thymic epithelial cells (TECs) are critical for T cell development and self-tolerance but are gradually lost with age. The existence of thymic epithelial progenitors (TEPCs) in the postnatal thymus has been inferred, but their identity has remained ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The DNA demethylase TET1 modifies the impact of maternal folic acid status on embryonic brain development

EMBO Reports
Folic acid (FA) is well known to prevent neural tube defects (NTDs), but we do not know why many human NTD cases still remain refractory to FA supplementation.

Endocannabinoid System Modulates Glial Responses and Motoneuron Preservation After Spinal Cord Ventral Root Axotomy

Neuroglia
Background/Objectives: Injuries to spinal ventral roots induce complex retrograde reactions that compromise motoneuron survival, synaptic organization, and glial responses, ultimately limiting the potential for regeneration.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Organotypic Slice Culture of Salamander Limbs: Identification and Investigation of Nerve Derived BMP2 in an Organotypic In Vitro Assay [PDF]

, 2014
Salamander limb regeneration is a nerve-dependent process. In the absence of nerves, blastema cells (i.e. cells that give rise to the new structure) will not proliferate.

Transcriptome pyrosequencing of the Antarctic brittle star Ophionotus victoriae

, 2013
Brittle stars are included within a whole range of species, which contribute to knowledge in the medically important area of tissue regeneration. All brittle stars regenerate lose limbs, but the rate at which this occurs is highly variable and species ...

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

FEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...
