1Naturally Occurring Self-Reactive CD4^+CD25^+ Regulatory T Cells: Universal Immune Code显示文摘Naturally occurring thymus-arisen CD4+CD25+ regulatory T (Treg) cells are considered to play a central role in self-tolerance. Precise signals that promote the development of Treg cells remain elusive, but considerable evidence suggests that costimulatory molecules, cytokines, the nature of the TCR and the niche or the context in which the T cell encounters antigen in the thymus play important roles. Analysis of TCR from Treg cells has demonstrated that a large proportion of this population has a higher avidity to self-antigen in comparison with TCR from CD4+CD25- cells and that peripheral antigen is required for their development, maintenance, or expansion. Treg cells have been shown to undergo expansion in the periphery, likely regulated by the presence of self-antigen. Many studies have shown that the involvement of Treg cells in the tolerance induction is antigen-specific, even with MHC-mismatched, in transplantation/graft versus host disease (GVHD), autoimmunity, cancer, and pregnancy. Theses studies concluded a vital role for self-reactive Treg cells in maintenance of the body integrity. Based on those studies, we hypothesize that self-reactive Treg cells are shared among all healthy individuals and recognize same self-antigens and their TCR encodes for few dominant antigens of each organ which defines the healthy self. These dominant self antigens can be regarded as “universal immune code”.Nafiseh Pakravan Agheel Tabar Molla Hassan Zuhair Muhammad Hassan 2007Cellular & Molecular Immunology2007,4,3:6
2纳米晶枝CuAu合金催化剂对二氧化碳电催化还原性能的研究显示文摘利用可再生清洁能源将CO_(2)转化为CO和其他小分子是合成含碳燃料的可观方法之一。间歇性可再生能源存储的重要策略之一是将二氧化碳进行电化学还原。选择具有高活性和稳定性的电催化剂对于电化学还原CO_(2)至关重要。在这项研究中,我们使用简单的电沉积方法合成了具有纳米晶枝状结构的CuAu合金电极。各项表征显示原子比约为1:1的CuAu纳米枝晶对CO_(2)的电化学还原具有出色的催化活性。合成的主要产物是H2和CO,这是合成气体是合成天然气,氨和甲醇合成的中间体。电化学阻抗谱(EIS)测量表明,相对于Cu和Au电沉积催化剂,CuAu纳米晶枝状催化剂具有相对低的电荷转移阻力。CuAu纳米枝晶催化剂是一种具有潜在的转化CO_(2)为合成气体的高活性电催化剂。Dylan Siltamaki 陈帅 Farnood Pakravan Jacek Lipkowski 陈爱成 2021电化学2021,27,3:2
