Control of immune response in an iPSC-based allogeneic cell therapy clinical trial for Parkinson's disease

1 month 4 weeks ago
Because the central nervous system (CNS) is an immune-privileged organ, it requires different immunosuppression strategies for cell therapies using induced pluripotent stem cells (iPSCs) compared with ones for organ transplantations. We recently conducted the first in-human clinical trial of a cell therapy for Parkinson's disease using allogeneic iPSCs (jRCT number: jRCT2090220384). All patients were transplanted with dopaminergic neural progenitors differentiated from iPSCs (iPSC-DANs), which...

The role of mitophagy in perioperative neurocognitive disorder: from mechanisms to implications

1 month 4 weeks ago
Perioperative neurocognitive disorder (PND) is a significant neurological complication in aging perioperativepatients, seriously impacting their postoperative recovery and cognition as well as quality of life. The occurrence of PND is closely related to various factors, including neuroinflammation and oxidative stress, while the exact mechanism is still unknown. Mitophagy is a specialized form of autophagy and maintains cellular homeostasis by selectively degrading damaged and dysfunctional...

Non-genetic neuromodulation with graphene optoelectronic actuators for disease models, stem cell maturation, and biohybrid robotics

1 month 4 weeks ago
Light can serve as a tunable trigger for neurobioengineering technologies, enabling probing, control, and enhancement of brain function with unmatched spatiotemporal precision. Yet, these technologies often require genetic or structural alterations of neurons, disrupting their natural activity. Here, we introduce the Graphene-Mediated Optical Stimulation (GraMOS) platform, which leverages graphene's optoelectronic properties and its ability to efficiently convert light into electricity. Using...
