| 1 | A human circulating immune cell landscape in aging and COVID-19显示文摘Age-associated changes in immune cells have been linked to an increased risk for infection.However,a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking.Here,we combined scRNA-seq,mass cytometry and sCATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19.We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector,cytotoxic,exhausted and reg-ulatory cells,along with increased late natural killer cells,age-associated B cells,inflammatory monocytes and age-associated dendritic cells.In addition,the expression of genes,which were implicated in coron-avirus susceptibility,was upregulated in a cell subtype-specific manner with age.Notably,COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senes-cence.Therefore,these findings suggest that a dysreg-ulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly. | Yingfeng Zheng Xiuxing Liu Wenqing Le Lihui Xie He Li Wen Wen Si Wang Shuai Ma Zhaohao Huang Jinguo Ye Wen Shi Yanxia Ye Zunpeng Liu Moshi Song Weiqi Zhang Jing-Dong J.Han Juan Carlos lzpisua Belmonte Chuanle Xiao Jing Qu Hongyang Wang Guang-Hui Liu Wenru Su | 2020 | Protein & Cell2020，11，10： | 10 |
| 2 | Applications and potentials of nanopore sequencing in the(epi)genome and(epi)transcriptome era显示文摘The Human Genome Project opened an era of(epi)genomic research,and also provided a platform for the development of new sequencing technologies.During and after the project,several sequencing technologies continue to dominate nucleic acid sequencing markets.Currently,Illumina(short-read),PacBio(long-read),and Oxford Nanopore(longread)are the most popular sequencing technologies.Unlike PacBio or the popular short-read sequencers before it,which,as examples of the second or so-called Next-Generation Sequencing platforms,need to synthesize when sequencing,nanopore technology directly sequences native DNA and RNA molecules.Nanopore sequencing,therefore,avoids converting mRNA into cDNA molecules,which not only allows for the sequencing of extremely long native DNA and full-length RNA molecules but also document modifications that have been made to those native DNA or RNA bases.In this review on direct DNA sequencing and direct RNA sequencing using Oxford Nanopore technology,we focus on their development and application achievements,discussing their challenges and future perspective.We also address the problems researchers may encounter applying these approaches in their research topics,and how to resolve them. | Shangqian Xie Amy Wing-Sze Leung Zhenxian Zheng Dake Zhang Chuanle Xiao Ruibang Luo Ming Luo Shoudong Zhang | 2021 | The Innovation2021，2，4： | 2 |
| 3 | Identification of Ubiquitinated Proteins from Human Multiple Myeloma U266 Cells by Proteomics显示文摘Objective To identify ubiquitinated proteins from complex human multiple myeloma (MM) U266 cells,a malignant disorder of differentiated human B cells.Methods Employing a globally proteomic strategy combining of immunoprecipitation,LC-MS/MS and SCX-LC-MS analysis to identified ubiquitination sites,which were identified by detecting signature peptides containing a GG-tag (114.1 Da) and an LRGG-tag (383.2 Da).Results In total,52 ubiquitinated proteins containing 73 ubiquitination sites of which 14 and 59 sites contained LRGG-tag and GG-tag were identified,respectively.Conclusion Classification analysis by of the proteins identified in the study based on the PANTHER showed that they were associated with multiple functional groups.This suggested the involvement of many endogenous proteins in the ubiquitination in MM. | JIA HongLing LIU ChaoWu GE Feng XIAO ChuanLe LU ChunHua WANG Tong HE QingYu | 2011 | Biomedical and Environmental Sciences2011，24，4： | 2 |
