The Identification of A Novel HIV-1 Second-Generation Recombinant form (CRF01_AE/CRF07_BC) Among Men Who Have Sex with Men in Jiangsu, China. Curr HIV Res 2021; 19:188-194. [PMID: 33106145 DOI: 10.2174/1570162x18666201026143200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 09/12/2020] [Accepted: 09/25/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND CRF01_AE and CRF07_BC are the two major HIV-1 virus strains circulating in China. The proportion of dominant subtypes (CRF01_AE and CRF07_BC) among MSM in Jiangsu province was over 80%. A large number of URFs have been found in China in recent years. OBJECTIVE This study aimed to report on novel HIV-1 recombinants. METHODS We constructed Phylogenetic trees using the maximum likelihood (ML) method with 1000 bootstrap replicates in IQ-TREE 1.6.8 software and determined recombination breakpoints using SimPlot 3.5.1. RESULTS We identified a novel, second-generation HIV-1 recombinant (JS020202) between CRF01_ AE and CRF07_BC. The analysis of near full-length genome (NFLG) showed there were at least 8 breakpoints in the virus, which differed from any previously identified CRF and URF around the world. CONCLUSION Novel diverse CRF01_AE/07_BC suggested the complexity trends of HIV-1 genetics. The emergency situation of diverse recombinant strains should be monitored continuously.

Abstract
A novel HIV-1 second-generation recombinant form (CRF01_AE/CRF07_BC) was isolated from an HIV-positive subject among men who have sex with men (MSM) in Guizhou province in Southwest China. Recombinant analyses of the near full-length genome suggested that the strain was composed of CRF01_AE and CRF07_BC with one region of CRF07-BC inserted into a CRF01-AE backbone. Further analysis indicated that the CRF01_AE regions of the recombinant were highly clustered together with a subcluster 4 lineage of CRF01_AE, which is exclusively circulating among MSM in China. The CRF07_BC region of the recombinant was clustered with the CRF07_BC cluster, which was identified among MSM. The emergence of the novel HIV-1 recombinant may be a harbinger of more novel intersubtypes recombinants occurring in Guizhou province in Southwest China, and was of great important in understanding the dynamics and complexity of the HIV-1 epidemic in this region.

Abstract
In recent years, men who have sex with men (MSM) have been the most affected population with fastest growing human immunodeficiency virus (HIV) prevalence in China. In our study, a novel CRF01_AE/07_BC HIV-1 recombinant form (TJIH0069), with four unique breakpoints in the pol, vpr, and nef gene regions, was identified among MSM in Tianjin City in north China. The CRF01_AE regions (regions I, III, and V) of the recombinant are all clustered together with a previously described sequence (HQ215555), which was exclusively circulating among MSM in Shijiazhuang city of Hebei Province in north China. The CRF07_BC regions (II and IV) are clustered with BJ070032 and JX960600, which were discovered from MSM population in north China. The continuous emergence of a similar pattern of recombinant strain between the two MSM-adapted existing circulating recombinant forms (CRFs) highlights the importance to monitor potential new CRFs for early and precise control and prevention.

Abstract
Genome recombination is a major strategy employed by HIV to generate new variants for the benefit of escaping immune surveillance. Near full-length genome phylogenic analysis was utilized to characterize HIV diversity in a male patient in Guangdong, China. The result showed a unique recombinant form (URF) composed of two circulating recombinant forms, CRF01_AE (92%) and CRF07_BC (8%), using six recombinant breakpoints, nt 2794, 3092, 4482, 5988, 7021, and 7722. The emergence of this URF indicates that HIV-1 co-infection or super-infections are common. The increasing genetic complexity of the HIV-1 epidemic in China warrants continued investigation.

Abstract
Recently multiple kinds of unique recombinant forms of HIV-1 CRF01_AE/CRF07_BC were identified in China. In this study, we report another near full-length genome of a novel recombinant form (SN121) between CRF01_AE and CRF07_BC from an HIV-1-infected male through heterosexual behavior in Shaanxi province, China. The analysis of SN121 showed that the genome composed of seven interlaced segments, including three CRF07_BC and four CRF01_AE segments with CRF01_AE as the backbone. Six breakpoints were observed in the pol and env gene regions, which are different from the previously identified CRF01_AE/07_BC recombinant forms in China. This novel emerging recombinant form suggested the complicated genetic diversity and the active local transmission of HIV-1 in Shaanxi province. Further monitoring should be performed to elucidate the possible molecular evolution of this novel recombinant form.

Abstract
Here, we report the genetic diversity of HIV-1 and emergence of novel HIV-1 unique recombinant forms (URF) in both HIV-infected intravenous drug users (IDU) and men who have sex with men (MSM) in Guangzhou, China. We further characterized a novel URF strain isolated from an HIV-infected MSM, GD698. Near full-length genome (NFLG) phylogenic analysis showed that this novel URF was composed of CRF07_BC and CRF55_01B, with two recombinant breakpoints (nt 6,003 and 8,251 relative to the HXB2 genome) in the vpu/env and env genes, respectively. Twenty six percent of the genome is classified as CRF55_01B, spanning part of vpu and most of the env gene. The remaining 74% of the genome is classified as CRF07_BC. Both the backbone CRF07_BC sequence and CRF55_01B fragment were clustered with the HIV-1 isolates found in MSM. The emergence of the novel HIV-1 recombinant indicates the ongoing recombinants derived from the CRF07_BC and CRF55_01B isolates, and provides critical insights into our understanding of the dynamics and complexity of the HIV-1 epidemic in China.

Abstract
CRF01_AE and CRF07_BC are the two major circulating recombinant forms (CRFs) in China. Furthermore, many kinds of unique recombinant forms (URFs) between CRF01_AE and CRF07_BC were recently identified in China. Here we detected a novel recombinant of CRF07_BC/CRF01_AE, whose genome structure is distinctly different from other URFs reported before. The phylogenetic analysis of the near full-length sequence of 15zj032 reveals that three regions of CRF01_AE insert into the CRF07_BC backbone. Recently, the continued emergence of novel URFs implies that super infections of different subtypes of HIV-1 are common in China and should be given enough importance.

Abstract
Increasing second-generation recombinant forms (CRF01_AE/07_BC) have been detected in China recently. Here, we isolated a novel CRF01_AE/07_BC second-generation recombinant form in HIV-1-positive Nei Monggoi's heterosexuals with one CRF07_BC inserted into the CRF01_AE backbone. Polygenetic analyses showed that the CRF01_AE region was grouped with the previously reported cluster 5 lineage, which spreads among the sexual population in north of China, inferring that this recombinant event occurred through heterosexual contact in the north of China possibly. The growing emergence of recombinant forms means coexistence of multiple strains and complexity of the HIV-1 epidemic, which reminds us of the urgent necessity to focus the HIV surveillance among the high-risk populations nationwide in China, particularly to enhance preventive measures in HIV-1 low-prevalence areas.

Abstract
A novel second-generation CCR5-tropic HIV-1 recombinant virus (XC2014EU09) was identified here, which was isolated from a HIV-positive man who had sex with men (MSM) in Sichuan, China. Phylogenic analyses showed that XC2014EU09 was composed of two well-established circulating recombinant forms (CRF01_AE and CRF07_BC). Different from the other four reported CRF01_AE/CRF07_BC recombinant forms, three recombinant breakpoints of XC2014EU09 with four fragments were observed in the vpr, env, and nef genes, respectively, as follows: ICRF01_AE (636-5,843 nt), IICRF07_BC (5,844-8,393 nt), IIICRF01_AE (8,394-9,119 nt), and IVCRF07_BC (9,120-9,600 nt). The emergence of CRF01_AE/CRF07_BC recombinant strain indicates the increasing complexity of the HIV-1 epidemic among the MSM group in China.

Abstract
HIV-1 CRF07_BC became prevalent in Taiwan after the epidemic among injection drug users (IDUs). We describe a unique recombinant form (URF) consisting of CRF01_AE and CRF07_BC (named URF_0107-H8) genes detected from an IDU. The 8.8 kb near full-length genome of URF_0107-H8 had a CRF01_AE backbone with two CRF07_BC fragments in the reverse transcriptase and integrase region [RT-Int; HXB2 nucleotide (nt) positions 2942-4709] and within the envelop (nt 8467-8722) gene. Phylogenetic analyses revealed that its 1.8 kb RT-Int sequence clustered with those of CRF07_BC strains from Taiwan, while sequences of CRF01_AE portions were more similar to those of Central African origin than contemporaneous CRF01_AE isolates in Taiwan or prevalent in East or Southeast Asia. Recombination breakpoints and phylogenetic relationships of URF_0107-H8 were different from those of CRF01_AE/CRF07_BC URFs previously reported from China. This highlighted the importance of continual monitoring of genetic evolution of HIV strains and the emergence of new recombinants.

Abstract
CRF01_AE and subtype B are the two major HIV-1 clades circulating in China. Heterosexual transmission is the predominant route for the spread of HIV and heterosexuals often include men who have sex with men and intravenous drug users. Furthermore, many kinds of circulating recombinant forms (CRF) and unique recombinant forms (URF) between CRF01_AE and subtype B were recently identified in Southeast Asia. Therefore it is inevitable that the new recombinant of CRF01_AE/B will emerge among them. Here we identified a novel recombinant of CRF01_AE/B, isolated from heterosexuals, which has a distinctly different genome structure from other CRF01Bs and URFs reported before. The analysis of the near full-length sequence of JS2011001 shows that it is composed of at least five interlaced CRF01_AE and B segments. Recently, many kinds of URFs and CRFs began to prevail within a short period in China, which implies that a mix of HIV-1 infections is common in China and more attention should focus on it.
