Oxygenation by Intravascular Photosynthesis Reduces Kidney Damage During ex Vivo Preservation

Several clinical issues are associated with reduced oxygen delivery to tissues due to impaired vascular perfusion; moreover, organs procured for transplantation are subjected to severe hypoxia during preservation. Consequently, alternative tissue oxygenation is an active field in biomedical research where several innovative approaches have been recently proposed. Among these, intravascular photosynthesis represents a promising approach as it relies on the intrinsic capacity of certain microorgan...

Development of a Hibernation‐Inspired Preservation Strategy to Enhance the Clinical Translation of Photosynthetic Biomaterials

Photosynthetic biomaterials have emerged as a promising approach for delivering oxygen and other bioactive molecules in several biomedical applications. This technology is based on the use of standard biomaterials loaded with photosynthetic cells for the controlled release of oxygen at the target site. However, as well as for other cell-based approaches, a main drawback for their clinical translation is the low shelf-life of living materials. Here, the potential of inducing a dormant hibernation...

Frontiers | The Reparative Abilities of Menstrual Stem Cells Modulate the Wound Matrix Signals and Improve Cutaneous Regeneration

Considerable advances have been made toward understanding the cellular and molecular mechanism of wound healing, however, treatments for chronic wounds remain elusive. Emerging concepts utilizing mesenchymal stem cells (MSCs) from umbilical cord, adipose tissue and bone marrow have shown therapeutical advantages for wound healing. Based on this positive outcome, efforts to determine the optimal sources for MSCs are required in order to improve their migratory, angiogenic, immunomodulatory, and r...

Targeting PERK signaling with the small molecule GSK2606414 prevents neurodegeneration in a model of Parkinson's disease

These cells were the focus of our study. The pathogenic role of dysregulated PERK-eIF2α-P signaling in neurons has been well characterized across the spectrum of neurodegenerative disorders (Grande et al., 2018; Halliday et al., 2015, 2017; Hoozemans et al., 2005, 2007; Kim et al., 2014; Mercado et al., 2018; Moreno et al., 2012, 2013; Radford et al., 2015; Stutzbach et al., 2013). PERK-P has been detected in astrocytes from human tauopathy diseases (Nijholt et al., 2012), but the pathogenic eff...

Gene therapy in Parkinson's disease: targeting the... : Neural Regeneration Research

Parkinson's disease (PD) is the second most common neurodegenerative disease affecting 1% of the population over 60 years of age. The progressive degeneration of dopaminergic neurons at the substantia nigra pars compacta (SNpc) results in a severe and gradual depletion of dopamine content in the striatum, a phenomena that is responsible for the characteristic motor symptoms of this disease. There is no cure for PD and available treatments only aim to restore dopamine deficits. Administration of...

Frontiers | ER proteostasis disturbances in Parkinson's disease: novel insights

Parkinson's disease (PD) is characterized by the selective loss of dopaminergic neurons of the substantia nigra pars compacta (SNpc). Proteostasis impairment at the level of the endoplasmic reticulum (ER) is emerging as a driving factor of dopaminergic neuron loss in PD. ER stress engages the activation of an adaptive reaction known as the unfolded protein response (UPR) to recover proteostasis or trigger apoptosis of damaged cells. The therapeutic potential of the UPR as a target has been recen...
