Richard Lerner was a singularity. During his tenure, Scripps Research was transformed into a biomedical powerhouse. He rapidly built remarkable strength in chemical and structural biology, immunology, cell and molecular biology, and molecular medicine. Not to stop there, he also instituted a new graduate program that consistently ranked in the top ten in the US. At the same time, he was a prolific author of scientific papers, which poured out of his own laboratory with colleagues at Scripps Research and collaborators throughout the world. These and many other aspects of his brilliant career and contributions are well documented and discussed elsewhere.

Here I chose to avoid redundancy and focus instead on a few of the personal encounters, which give some sense of Richard's character and spirit. An essential part of Richard's success was his wife Nicola (Nicky), herself an MD, who worked tirelessly to enable him to achieve what he did. Early on, my wife Cleo and Nicky became close friends. This relationship facilitated social occasions, where we would be with the Lerner's at a dinner or event, sometimes at our home or at theirs, but also with guests at various restaurants in La Jolla. As a result, my understanding of Richard was broadened beyond that received from the many discussions and meetings at Scripps Research. This understanding was helpful during those times when we faced serious challenges and he, like all of us when under stress, needed support.

In what is written below, I have used plain language to relate some of my memories and reflections. Richard was a friend and colleague and taught me much, especially the power of a vision, of belief in that vision and of the will to make the effort to bring it to pass.

理查德·勒纳是个奇点。在他任职期间,斯克里普斯研究公司转型为生物医学巨头。他在化学和结构生物学、免疫学、细胞和分子生物学以及分子医学方面迅速建立起了卓越的实力。不仅如此,他还设立了一个新的研究生项目,该项目在美国一直排名前十。与此同时,他还是一位多产的科学论文作者,他与斯克里普斯研究所的同事以及世界各地的合作者共同撰写了大量科学论文。这些以及他辉煌的职业生涯和贡献的许多其他方面在其他地方都有很好的记录和讨论。在这里,我选择避免冗余,而是把重点放在一些个人遭遇上,这让我对理查德的性格和精神有了一些了解。理查德成功的一个重要因素是他的妻子尼古拉(尼基饰),她自己也是一名医学博士,她不知疲倦地工作,使他能够取得他所做的一切。早些时候,我的妻子克莱奥和尼基成为了亲密的朋友。这种关系促进了社交活动,我们会和勒纳一家一起参加晚宴或活动,有时在我们家,有时在他们家,但也会在拉霍亚的各种餐馆与客人一起。因此,我对理查德的了解超出了在斯克里普斯研究公司的许多讨论和会议所获得的。这种理解在我们面临严峻挑战的时候很有帮助,他和我们所有人一样,在压力下需要支持。在下文中,我用通俗易懂的语言讲述了我的一些记忆和感想。理查德是我的朋友和同事,他教会了我很多东西,尤其是愿景的力量、对愿景的信念以及为实现愿景而努力的意志。

Richard Lerner had many achievements in his outstanding career. He will perhaps be remembered most for taking the helm of Scripps Research, following the founding by and tenure of Frank Dixon, and building one of the most successful biomedical research institutes in the world. Two Nobel prizes at Scripps in the past two years and one of them a second Nobel speaks for itself. But I want to cover what many consider Richard's finest scientific achievement- the development of a whole new approach to making antibodies that has been revolutionary to many aspects of basic science and medicine. I was very fortunate to be a part of that development and I give an account here and my memories of Richard during that time.

理查德·勒纳在他杰出的职业生涯中取得了许多成就。在弗兰克·迪克森(Frank Dixon)创立并任职之后,他执掌斯克里普斯研究中心(Scripps Research),并建立了世界上最成功的生物医学研究机构之一,这可能是他最令人难忘的经历。在过去的两年里,斯克里普斯学院获得了两项诺贝尔奖,其中一项是第二个诺贝尔奖。但我想说的是理查德最杰出的科学成就——他发明了一种全新的制造抗体的方法,这对基础科学和医学的许多方面都是革命性的。我很幸运能成为发展的一部分,我在这里讲述我对理查德那段时间的回忆。

Richard was mainly known as a gifted scientist, a charismatic leader, and an original and creative President. And he was my good friend and a role model for over three decades. The term impossible was not part of his vocabulary. I′ve learned from him that there is no limit to imagination and creativity, no limit to the number of assignments one can fulfill, and no limit to the magnitude of a dream one can turn into reality. Richard was blessed with the unique talent to quickly decipher the essence of people‘s thoughts and discover the hidden parts of their personalities, which allowed him to focus on what he defined as the most valuable issues and productive discussions. My experience with him included the joy of scientific discovery, the silent mode of human communication, the power of commitment and dedication, and the wildest sense of humor. Now, nearly two years after his departure, I feel free and obliged to share unknown stories and anecdotes that illuminate various facets of his personality.

理查德主要被认为是一位天才科学家,一位有魅力的领导者,一位有独创性和创造力的总统。他是我的好朋友,也是我三十多年来的榜样。他的字典里没有“不可能”这个词。我从他身上学到了想象力和创造力是没有限制的,一个人能完成的任务是没有限制的,一个人能把梦想变成现实的程度是没有限制的。理查德被赋予了一种独特的才能,能够迅速破译人们思想的本质,发现他们个性中隐藏的部分,这使他能够专注于他所定义的最有价值的问题和富有成效的讨论。我和他在一起的经历包括科学发现的喜悦、人类交流的沉默方式、承诺和奉献的力量,以及最狂野的幽默感。现在,在他离开近两年之后,我感到自由,也有义务分享一些不为人知的故事和轶事,这些故事和轶事揭示了他性格的各个方面。

Abstract RE‐Au‐Si (RE=Ho, Tb) systems are 1/1 Tsai‐type quasicrystalline approximants with a cluster center decoration that can vary from a disordered tetrahedron to a rare‐earth atom. The local atomic structure of three different samples was observed by scanning transmission electron microscopy and interpreted in the light of high‐angle annular dark field simulated scanning transmission electron microscopy images. It is found that the combination of these two methods allows to identify differences in the chemical decoration of the cluster centers through quantitative analysis of line profiles.
RE - Au - Si (RE=Ho, Tb)体系是具有团簇中心修饰的1/1 Tsai型准晶近似体,可以是无序四面体,也可以是稀土原子。用扫描透射电子显微镜观察了三种不同样品的局部原子结构,并用高角度环形暗场模拟扫描透射电子显微镜图像对其进行了解释。研究发现,这两种方法的结合可以通过对线形的定量分析来识别簇中心化学装饰的差异。

In recent decades, electro-organic synthesis is indubitably emerging as a cornerstone of modern organic chemistry. Electrochemical organic transformations especially reduction reactions have made massive advancements in the last few years because of their sustainable and environ-friendly nature. Electro-reductive protocols can be used as a promising substitute for conventional reductants by expelling the requirement of the stoichiometric amount of metal reductants. The major challenges for these electro-reductive reactions are primarily the use of a sacrificial electrode and divided cells. These limitations can be resolved through smart reaction planning by employing cheap sacrificial reagents or paired electrolysis without compromising the sustainable viewpoint. Considering the rapid enhancement in this field, imparting an intangible understanding of this evolving area is essential and substantial. In this review, we portrayed the electrochemical reductive transformations of C−C and C−O bonds after 2015 along with detailed mechanistic insights.

近几十年来,电有机合成已无可争议地成为现代有机化学的基石。电化学有机转化,尤其是还原反应,因其可持续和环保的特性,在过去几年中取得了巨大的进步。电还原反应不需要等量的金属还原剂,因此可以替代传统的还原剂。这些电还原反应面临的主要挑战是使用牺牲电极和分隔电池。这些限制可以通过采用廉价的牺牲试剂或配对电解进行智能反应规划来解决,而不会影响可持续观点。考虑到这一领域的快速发展,传授对这一不断发展的领域的无形理解至关重要。在这篇综述中,我们描绘了 2015 年之后 C-C 和 C-O 键的电化学还原转化以及详细的机理见解。

Abstract The NLRP3 inflammasome is a cytosolic protein complex that regulates innate immune signaling in response to diverse pathogenic insults through the proteolytic processing and secretion of pro‐inflammatory cytokines such as IL‐1β. Hyperactivation of NLRP3 inflammasome signaling is implicated in the onset and pathogenesis of numerous diseases, motivating the discovery of new strategies to suppress NLRP3 inflammasome activity. We sought to define the potential for the proteostasis regulator AA147 to inhibit the assembly and activation of the NLRP3 inflammasome. AA147 is a pro‐drug that is metabolically converted to a reactive metabolite at the endoplasmic reticulum (ER) membrane to covalently modify ER‐localized proteins such as protein disulfide isomerases (PDIs). We show that AA147 inhibits NLRP3 inflammasome activity in monocytes and monocyte‐derived macrophages through a mechanism involving impaired assembly of the active inflammasome complex. This inhibition is mediated through AA147‐dependent covalent modification of PDIA1. Genetic depletion or treatment with other highly selective PDIA1 inhibitors similarly blocks NLRP3 inflammasome assembly and activation. Our results identify PDIA1 as a potential therapeutic target to mitigate NLRP3 inflammasome‐mediated pro‐inflammatory signaling implicated in etiologically diverse diseases.
NLRP3炎性小体是一种胞质蛋白复合物,通过蛋白水解加工和促炎细胞因子(如IL - 1β)的分泌来调节先天免疫信号,以应对多种致病性损伤。NLRP3炎性小体信号的过度激活与许多疾病的发病和发病机制有关,促进了抑制NLRP3炎性小体活性的新策略的发现。我们试图确定蛋白平衡调节剂AA147抑制NLRP3炎症小体的组装和激活的潜力。AA147是一种前药物,在内质网(ER)膜上代谢转化为反应性代谢物,共价修饰内质网定位的蛋白质,如蛋白质二硫异构酶(pdi)。研究表明,AA147抑制单核细胞和单核细胞源性巨噬细胞中NLRP3炎性体的活性,其机制涉及活性炎性体复合物的组装受损。这种抑制是通过a147依赖性PDIA1共价修饰介导的。基因缺失或使用其他高选择性PDIA1抑制剂治疗同样会阻断NLRP3炎性体的组装和激活。我们的研究结果确定PDIA1是一个潜在的治疗靶点,可以减轻NLRP3炎症小体介导的炎症前信号,这与多种病因疾病有关。

Abstract The proteasome is comprised of multiple subunits that catalyze the degradation of proteins to maintain cellular homeostasis. The proteasome targets protein substrates by two different pathways. The ubiquitin‐dependent pathway requires proteins to be labeled with a ubiquitin tag to signal for degradation by the 26S isoform of the proteasome. Protein degradation through this pathway declines during age progression. The ubiquitin‐independent pathway utilizes the 20S proteasome isoform. It can degrade misfolded and intrinsically disordered proteins to decrease cellular stress. Age‐related protein accumulation and aggregation can occur due to the decreased activity and expression of the proteasome. Protein accumulation causes increased cellular stress which can contribute to disease progression. Increasing proteasome activity could serve as a solution to eliminating and preventing protein accumulation. Studies have shown the value of the proteasome as a therapeutic entity to mitigate cellular stress. This perspective explores the link between proteasome activity and cellular stress caused by age‐related misfolded protein accumulation.
蛋白酶体由多个亚基组成,这些亚基催化蛋白质降解以维持细胞内稳态。蛋白酶体通过两种不同的途径靶向蛋白质底物。泛素依赖途径需要用泛素标签标记蛋白质,以指示蛋白酶体的26S异构体降解。通过这一途径的蛋白质降解随着年龄的增长而下降。泛素非依赖性途径利用20S蛋白酶体异构体。它可以降解错误折叠和内在无序的蛋白质,以减少细胞压力。由于蛋白酶体的活性和表达降低,年龄相关的蛋白质积累和聚集可能发生。蛋白质积累导致细胞压力增加,从而导致疾病进展。提高蛋白酶体活性可以作为消除和防止蛋白质积累的解决方案。研究表明,蛋白酶体作为一种治疗实体的价值,以减轻细胞应激。这一观点探讨了蛋白酶体活性与由年龄相关的错误折叠蛋白积累引起的细胞应激之间的联系。

Abstract Amyloid fibril deposition causes progressive tissue damage and organ failure in the systemic amyloid diseases, and therapies that suppress aggregation lead to clinical benefit. Small molecules that prevent aggregation by binding to precursor proteins are effective for amyloid transthyretin (ATTR) amyloidosis. However, in amyloid light chain (AL) amyloidosis, fibrils are formed by antibody light chains and every patient has a unique protein sequence that aggregates. The highly diverse sequences of these light chains appear to determine whether an individual is at risk of amyloidosis, the distribution of amyloid deposits and the progression of disease. Light chains are therefore challenging drug targets. This review explores the parallels between AL amyloidosis and ATTR amyloidosis to describe the discovery of small molecules that can stabilize light chains. These molecules have potential as therapies for AL amyloidosis, highlighting potential opportunities for drug discovery in other diseases of protein misfolding.
淀粉样蛋白原纤维沉积在全身性淀粉样蛋白疾病中可导致进行性组织损伤和器官衰竭,抑制其聚集的治疗可带来临床益处。通过结合前体蛋白来阻止聚集的小分子对淀粉样转甲状腺素(ATTR)淀粉样变性有效。然而,在淀粉样蛋白轻链(AL)淀粉样变性中,原纤维是由抗体轻链形成的,每个患者都有独特的蛋白质序列聚集。这些轻链的高度多样化的序列似乎决定了一个人是否有淀粉样变的风险,淀粉样蛋白沉积的分布和疾病的进展。因此,轻链是具有挑战性的药物靶点。本综述探讨了AL淀粉样变性和ATTR淀粉样变性之间的相似之处,以描述可以稳定轻链的小分子的发现。这些分子有可能作为AL淀粉样变性的治疗方法,突出了在其他蛋白质错误折叠疾病中发现药物的潜在机会。
