Understanding the link between neuronal responses (NRs) and metabolic signals is fundamental to our knowledge of brain function and it is a milestone in our efforts to interpret data from modern non invasive optical techniques such as fMRI, which are based on the close coupling between metabolic demand of active neurons and local changes in blood flow. The challenge is to unravel the link. Here...

Abstract Background DHA‐H (2‐hydroxy‐docosahexaenoic acid) is a promising therapeutic approach for Alzheimer’s Disease (AD). gives rise to dose‐dependent increased levels of HPA (Heneicosapentaenoic in blood plasma and brain whereas remains virtually absent from the DHA‐H‐treated mice. Oral administration transgenic model AD (5xFAD mice) induces significative cognitive recovery. However, molecu...

Most past studies of the biophysical regulation of stem cell differentiation have focused on initial lineage commitment or proximal differentiation events. It would be valuable to understand whether biophysical inputs also influence distal endpoints more closely associated with physiological function, such as subtype specification in neuronal differentiation. To explore this question, we cultur...

We investigated the cell viability, proliferative capacity and neuronal differentiation potential of canine bone marrow stromal cells (BMSCs) after cryopreservation. BMSCs were cryopreserved using cryoprotectant solutions with 10% DMSO and 10% FBS (DF group) or without DMSO and FBS (DF-free group); fresh BMSCs were used as a control. The cell viability and proliferative capacity of BMSCs were s...

Immune cells are thought to be involved in a destructive cycle of sterile cerebral inflammatory responses neurodegenerative diseases such as Parkinson’s Disease (PD). Despite their peripheral origin, immune may enter the CNS due impaired blood–brain barrier function and potentially contribute neuronal damage. Hence, specific characteristics peripherally activated could help understanding neurod...

PURPOSE In several species the retinal pigment epithelium (RPE) has the potential to transdifferentiate into retinal cells to regenerate functional retinal tissue after injury. However, this capacity for regeneration is lost in mammals. The synthetic retinoic acid derivative, fenretinide [N(4-hydroxyphenyl) retinamide], induces a neuronal-like phenotype in the human adult retinal pigment epithe...

The doublecortin (DCX) gene encodes a 40-kDa microtubule-associated protein specifically expressed in neuronal precursors of the developing and adult CNS. Due to its specific expression pattern, attention was drawn to DCX as a marker for neuronal precursors and neurogenesis, thereby underscoring the importance of its promoter identification and promoter analysis. Here, we analysed the human DCX...

The targeting of sensory afferent neurons in the leech CNS occurs in two discrete steps that are mediated via different carbohydrate recognitions, as shown by molecular perturbations of cultured embryos. A constitutive carbohydrate marker that is generic to all of these neurons mediates their initial defasciculation and arborization across the entire target region via mannose-specific recogniti...

Cutaneous malignant melanomas share a number of molecular attributes such as limitless replicative potential that define capabilities acquired by most malignancies. Accordingly, much effort has been focused on evaluating and validating protein markers related to these capabilities to function as melanoma prognostic markers. However, a few studies have also highlighted the prognostic value of ma...

PURPOSE Cell lines are frequently used to elucidate mechanisms of disease pathophysiology. Yet extrapolation of results with cell lines to neurodegenerative disorders is difficult because they are mitotic and usually have other non-neuronal properties. The RGC-5 cell line has many features of retinal ganglion cells (RGCs). Despite its expression of Thy-1 and NMDA receptors, as found in primary ...
