Immunology and Infection A High-Throughput Multiplexed Screening for Type 1 Diabetes, Celiac Diseases, and COVID-19 Xiaofan Jia*1, Ling He*1,2, Dongmei Miao1, Caiguo Zhang1, Marian Rewers1, Liping Yu1 1Barbara Davis Center for Diabetes, University of Colorado School of Medicine, 2Department of Endocrinology, Guangzhou First People’s Hospital, School of Medicine, South China University of Technology In line with the urgent need for screening for type 1 diabetes, celiac disease, and coronavirus disease 2019, we developed a high throughput 6-Plex electrochemiluminescence assay to simultaneously detect all four islet autoantibodies, tissue transglutaminase autoantibodies, and antibodies to the receptor binding domain of severe acute respiratory syndrome coronavirus 2. Neuroscience Caenorhabditis elegans as a Model System for Discovering Bioactive Compounds Against Polyglutamine-Mediated Neurotoxicity Qiangqiang Wang*1, Ju Zhang*2, Yiyi Jiang1,3, Yue Xiao1, Xiaomin Li3, Xinliang Mao3, Zebo Huang1 1Institute for Food Nutrition and Human Health, School of Food Science and Engineering, South China University of Technology, 2School of Bioscience and Bioengineering, Hebei University of Economics and Business, 3Perfect Life & Health Institute Here, we present a protocol to assess the neuroprotective activities of test compounds in Caenorhabditis elegans, including polyglutamine aggregation, neuronal death, and chemoavoidance behavior, as well as an exemplary integration of multiple phenotypes. Medicine A High-Throughput Electrochemiluminescence 7-Plex Assay Simultaneously Screening for Type 1 Diabetes and Multiple Autoimmune Diseases Xiaofan Jia*1,2, Ling He*1,3, Yong Gu1, Hilary High1, Liping Yu1 1Barbara Davis Center for Diabetes, University of Colorado School of Medicine, 2Department of Endocrinology, Beijing Hospital, National Center of Gerontology; Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, 3Department of endocrinology, Guangzhou First People's Hospital, School of Medicine, South China University of Technology We model a simple multiplexed ECL assay that combines 7 autoantibody assays together. The assay is capable of screening for T1D and multiple other autoimmune diseases, simultaneously, including celiac disease, autoimmune thyroid disease, and autoimmune polyglandular syndrome 1. Developmental Biology An Ectopic Chemokine Expression Model for Testing Macrophage Recruitment In Vivo Yunyun Jiang1, Jiahao Chen1, Jin Xu2 1Department of Developmental Biology, School of Basic Medical Sciences, Southern Medical University, 2Division of Cell, Developmental and Integrative Biology, School of Medicine, South China University of Technology To test the effect of a chemokine on macrophage recruitment in vivo, the whole mount in situ hybridization was used to detect the ectopic expression of the chemokine, and immunostaining was used to label macrophages. Live imaging was used for real-time observation of macrophage migration. Chemistry Synthesis of Graphene Nanofluids with Controllable Flake Size Distributions Du Baolei1, Jian Qifei1 1Department of Mechanical and Automotive Engineering, South China University of Technology A method for synthesizing graphene nanofluids with controllable flake size distributions is presented.
