Inhibition of HIV early replication by the p53 and its downstream gene p21
Virology Journal - Tập 15 - Trang 1-13 - 2018
Binshan Shi, Hamayun J. Sharifi, Sara DiGrigoli, Michaela Kinnetz, Katie Mellon, Wenwei Hu, Carlos M. C. de Noronha
The tumor suppressor gene p53 has been found to suppress HIV infection by various mechanisms, but the inhibition of HIV at an early stage of replication by host cell p53 and its downstream gene p21 has not been well studied. VSV-G pseudotyped HIV-1 or HIV-2 viruses with GFP or luciferase reporter gene were used to infect HCT116 p53+/+ cells, HCT116 p53−/− cells and hMDMs. The infections were detec... hiện toàn bộ
Chinese highly pathogenic porcine reproductive and respiratory syndrome virus exhibits more extensive tissue tropism for pigs
Virology Journal - Tập 9 - Trang 1-6 - 2012
Limin Li, Qian Zhao, Xinna Ge, Kedao Teng, Yu Kuang, Yanhong Chen, Xin Guo, Hanchun Yang
The highly pathogenic porcine reproductive and respiratory syndrome virus (PRRSV) emerging in China exhibits high fatality to pigs. However, the mechanism related to the increased pathogenicity of the virus remains unclear. In the present study, the differences in tissue tropism between the highly pathogenic PRRSV strain (JXwn06) and the low pathogenic PRRSV strain (HB-1/3.9) were investigated usi... hiện toàn bộ
Abnormal CD4 + T helper (Th) 1 cells and activated memory B cells are associated with type III asymptomatic mixed cryoglobulinemia in HCV infection
Virology Journal - Tập 12 - Trang 1-13 - 2015
Fanyun Kong, Wei Zhang, Bo Feng, Henghui Zhang, Huiying Rao, Jianghua Wang, Xu Cong, Lai Wei
Mixed cryoglobulinemia (MC) in hepatitis C virus (HCV) infection is associated with abnormal immune responses mediated by T cells and B cells, while the relationships of different subsets of CD4 + T helper (Th) cells, B cells and associated cytokines with type III asymptomatic MC in HCV infection are poorly understood. Fifty-four chronic hepatitis C (CHC) patients and 23 healthy controls (HCs) wer... hiện toàn bộ
Inhibition of p38MAPK and CD137 signaling reduce dengue virus-induced TNF-α secretion and apoptosis
Virology Journal - Tập 10 - Trang 1-7 - 2013
Amar Nagila, Janjuree Netsawang, Aroonroong Suttitheptumrong, Atthapan Morchang, Sasiprapa Khunchai, Chatchawan Srisawat, Chunya Puttikhunt, Sansanee Noisakran, Pa-thai Yenchitsomanus, Thawornchai Limjindaporn
Hepatic injury in dengue virus (DENV) infection is authenticated by hepatomegaly and an upsurge in transaminase levels. DENV replicates in hepatocytes and causes hepatocyte apoptosis both in vitro and in vivo. Understanding the molecular mechanisms of DENV-induced hepatic injury could facilitate the development of alternate chemotherapeutic agents and improved therapies. The p38 mitogen-activated ... hiện toàn bộ
Isolation and pathogenicity of porcine circovirus type 2 in mice from Guangxi province, China
Virology Journal - Tập 20 - Trang 1-11 - 2023
Qiulin Jiao, Liuyue Yang, Xiangzu Liu, Yanwen Wen, Linxing Tian, Ping Qian, Huanchun Chen, Xiangmin Li
Porcine circovirus type 2 (PCV2), a member of the genus Circovirus and family Circoviridae, is a closed, small, circular, and single-stranded DNA virus, and it is a crucial swine pathogen of porcine circovirus-associated diseases (PCVADs). PCV2 was first detected in PK-15(ATCC-CCL) cells in 1974, which has caused significant economic loss to the swine industry throughout the world. And the first c... hiện toàn bộ
Morphological evidence for phages in Xylella fastidiosa
Virology Journal - Tập 5 - Trang 1-4 - 2008
Jianchi Chen, Edwin L Civerolo
Presumptive phage particles associated with Xylella fastidiosa strain Temecula-1 grown in PW broth were observed by transmission electron microscopy (TEM) in ultrathin sections of bacterial cell-containing low speed centrifugation pellets and in partially purified preparations from CsCl equilibrium centrifugation density gradients. Ultrathin-sectioned cell pellets contained icosahedral particles o... hiện toàn bộ
Identification and complete genome sequencing of paramyxoviruses in mallard ducks (Anas platyrhynchos) using random access amplification and next generation sequencing technologies
Virology Journal - Tập 8 - Trang 1-11 - 2011
Toon Rosseel, Bénédicte Lambrecht, Frank Vandenbussche, Thierry van den Berg, Steven Van Borm
During a wildlife screening program for avian influenza A viruses (AIV) and avian paramyxoviruses (APMV) in Belgium, we isolated two hemagglutinating agents from pools of cloacal swabs of wild mallards (Anas platyrhynchos) caught in a single sampling site at two different times. AIV and APMV1 were excluded using hemagglutination inhibition (HI) testing and specific real-time RT-PCR tests. To refin... hiện toàn bộ
Proteins in pregnant swine serum promote the African swine fever virus replication: an iTRAQ-based quantitative proteomic analysis
Virology Journal - - 2023
Jinke Yang, Xingguo Yuan, Yu Hao, Xijuan Shi, Xing Yang, Wenqian Yan, Lingling Chen, Dajun Zhang, Chaochao Shen, Dan Li, Zixiang Zhu, Xiangtao Liu, Haixue Zheng, Keshan Zhang
African swine fever (ASF) is a severe infectious disease caused by the African swine fever virus (ASFV), seriously endangering the global pig industry. ASFV possesses a large genome, strong mutation ability, and complex immune escape mechanisms. Since the first case of ASF was reported in China in August 2018, it has had a significant impact on social economy and food safety. In the present study,... hiện toàn bộ
Recognizing the role of Epstein-Barr virus in gastric cancer: transcriptomic insights into malignancy modulation
Virology Journal -
Tabassom Sedaghat Anbouhi, Hossein Sazegar, Ebrahim Rahimi
Abstract Background Studies show that Epstein-Barr virus (EBV) infection can play a role in malignancy and increase the risk of gastric cancer (GC). The objective of this research was to pinpoint genes whose expression may be influenced by EBV and play a role in the development of GC. Methods Candidate genes potentially susceptible to expression modulation in the presence of EBV were identified th... hiện toàn bộ
Fifteen new nucleotide substitutions in variants of human papillomavirus 18 in Korea
Virology Journal - Tập 17 - Trang 1-8 - 2020
Namhee Kim, Jeong Su Park, Ji Eun Kim, Jae Hyeon Park, Hyunwoong Park, Eun Youn Roh, Jong Hyun Yoon, Sue Shin
High-risk human papillomavirus (HPV) infection is an essential factor for the development of cervical cancer. HPV18 is the second most common carcinogenic HPV type following HPV16, but the lineages of HPV18 have been less well studied than those of HPV 16. The purpose of this study was to analyze the nucleotide variants in the E6, E7, and L1 genes of HPV18, to assess the prevalence of HPV18 varian... hiện toàn bộ
