| 1 | Neuro faces of beneficial T cells:essential in brain,impaired in aging and neurological diseases,and activated functionally by neurotransmitters and neuropeptides显示文摘T cells are essential for a healthy life,performing continuously:immune surveillance,recognition,protection,activation,suppression,assistance,eradication,secretion,adhesion,migration,homing,communications,and additional tasks.This paper describes five aspects of normal beneficial T cells in the healthy or diseased brain.First,normal beneficial T cells are essential for normal healthy brain functions:cognition,spatial learning,memory,adult neurogenesis,and neuroprotection.T cells decrease secondary neuronal degeneration,increase neuronal survival after central nervous system(CNS) injury,and limit CNS inflammation and damage upon injury and infection.Second,while pathogenic T cells contribute to CNS disorders,recent studies,mostly in animal models,show that specific subpopulations of normal beneficial T cells have protective and regenerative effects in seve ral neuroinflammatory and neurodegenerative diseases.These include M ultiple Sclerosis(MS),Alzheimer’s disease,Parkinson’s disease,Amyotrophic Lateral Sclerosis(ALS),stro ke,CNS trauma,chronic pain,and others.Both T cell-secreted molecules and direct cell-cell contacts deliver T cell neuroprotective,neuro regenerative and immunomodulato ry effects.Third,normal beneficial T cells are abnormal,impaired,and dysfunctional in aging and multiple neurological diseases.Different T cell impairments are evident in aging,brain tumors(mainly Glioblastoma),seve re viral infections(including COVID-19),chro nic stress,major depression,schizophrenia,Parkinson’s disease,Alzheimer’s disease,ALS,MS,stro ke,and other neuro-pathologies.The main detrimental mechanisms that impair T cell function are activation-induced cell death,exhaustion,senescence,and impaired T cell stemness.Fo urth,several physiological neurotransmitters and neuro peptides induce by themselves multiple direct,potent,beneficial,and therapeutically-relevant effects on normal human T cells,via their receptors in T cells.This scientific field is called 'Nerve-Driven Immunity'.The main neurotransmitters and neuropeptides that induce directly activating and beneficial effects on naive normal human T cells are:dopamine,glutamate,GnRH-Ⅱ,neuropeptide Y,calcitonin gene-related peptide,and somatostatin.Fifth, 'Personalized Adoptive Neuro-Immunotherapy'.This is a novel unique cellular immunotherapy,based on the 'Nerve-Driven Immunity' findings,which was recently designed and patented for safe and repeated rejuvenation,activation,and improvement of impaired and dysfunctional T cells of any person in need,by ex vivo exposure of the person’s T cells to neurotransmitters and neuropeptides.Personalized adoptive neuro-immunotherapy includes an early ex vivo personalized diagnosis,and subsequent ex vivo in vivo personalized adoptive therapy,tailo red according to the diagnosis.The Personalized Adoptive Neuro-Immunotherapy has not yet been tested in humans,pending validation of safety and efficacy in clinical trials,especially in brain tumors,chronic infectious diseases,and aging,in which T cells are exhausted and/or senescent and dysfunctional. | Mia Levite | 2023 | Neural Regeneration Research2023，18，6： | 4 |
| 2 | The influence of impurity on the critical thickness of the CeO_2 buffer layer for coated conductors显示文摘The lattice parameters, band structure, density of state and elastic constant of RE-doped CeO2 (RE=Sm, Gd, Dy), the buffer material for coated HTS conductors, are calculated using the plane-wave method with pseudopotentials based on the density functional theory (DFT) of first-principle. The rule and mechanism of the effect of rare earth impurity on the critical thickness of the CeO2 buffer layer are investigated. It is found that, in the range of the calculation, the changes of the lattice volume V and elastic constant E of CeO2 with the impurity are mainly determined by the increased electrons ne of the system. The relationship of the elastic constant E and increased electrons ne is established. It is indicated that the critical thickness of the CeO2 single buffer layer doped with Sm, Gd, and Dy may be enhanced by 22%, 43% and 33%, respectively. | PAN Min1, HUANG Zheng2, MA HuanFeng2, QIANG WeiRong2, WEI LianFu1, WANG Long2 & ZHAO Yong1,3 1 Key Laboratory of Magnetic Levitation Technologies and Maglev Trains (Ministry of Education of China), Superconductivity R&D Center (SRDC), Southwest Jiaotong University, Chengdu 610031, China 2 School of Physical Science and Technology, Southwest Jiaotong University, Chengdu 610031, China 3 Superconductivity Research Group, School of Materials Science and Engineering, University of New South Wale, Sydney, 2052 NSW, Australia | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
