This thesis presents studies on the interaction between the human T cell lymphotropic virus type 1 (HTLV-1) Tax protein and the 20S proteasome and the role of the interaction in cellular processes and the cytotoxic T cell (CTL) response against HTLV-1. The rapid translocation of Tax into the nucleus is described. Tax accumulates in the nucleus and forms unique bodies involved in transcriptional activation. It was further found that Tax associated with assembled nuclear 20S proteasomes and stimulated the chymotryptic and tryptic activities of the 20S proteasome, independent of the induction of the LMP2 and LMP7 proteasome subunits. Confocal microscopy revealed a partial colocalisation of Tax with nuclear proteasomes. A panel of Tax mutants was generated and their subcellular localisation and association with the 20S proteasome analysed. This analysis revealed that both the N- and C-terminus of Tax play a role in proteasome binding of Tax and further showed that proteasome binding was not sufficient for nuclear localisation of Tax. Therefore, Tax probably translocates into the nucleus prior to and independent of proteasome association. Tax specific CTL clones were generated and characterised using tetrameric MHC class I/peptide complexes. These CTL clones were used to investigate the requirements for processing and presentation of Tax for recognition by CTL. It was found that Tax was a metabolically very stable protein and that the presentation of the immunodominant Tax 11-19 epitope was dependent on the transporter associated with antigen presentation (TAP), independent of the expression of LMP2 and LMP7 proteasome subunits and resistant to treatment with the proteasome inhibitor lactacystin. It is proposed that the interaction between Tax and the 20S proteasome plays a role in Tax mediated transcriptional activation, leading to cellular activation and proliferation, and may not determine the immunodominance of Tax in the CTL response against HTLV-1.

Background: The World Health Organization (WHO) recommends immediate initiation of lifelong antiretroviral therapy (ART) for all people living with HIV, including pregnant women. As a result, an increasing number of women living with HIV conceive while taking ART, the vast majority of whom reside in low‐ and middle‐income countries (LMICs). We aimed to assess the association between timing of ART initiation and perinatal outcomes. Methods: We conducted a systematic literature review by searching PubMed, CINAHL (EBSCOhost), Global Health (Ovid), EMBASE (Ovid), and the Cochrane Central Register of Controlled Trials and four clinical trial databases (WHO International Clinical Trials Registry Platform, the Pan African Clinical Trials Registry, the ClinicalTrials.gov database, and the ISRCTN Registry) from 1 January 1980 to 28 April 2018. We identified studies reporting specific perinatal outcomes among pregnant women living with HIV according to timing of ART initiation and extracted data. Perinatal outcomes assessed were preterm birth (<37 weeks), very preterm birth (<32 weeks), low birthweight (<2500 g), very low birthweight (<1500 g), small for gestational age (<10th centile), very small for gestational age (<3rd centile) and neonatal death (<29 days). Random‐effects meta‐analyses examined perinatal outcomes associated with preconception and antenatal ART initiation as well as according to trimesters of antenatal initiation. We performed quality assessments and subgroup and sensitivity analyses, and assessed the effect of adjustment for confounders. This systematic review and meta‐analyses is registered with PROSPERO, number CRD42021248987. Results: Of 51 874 unique citations, 25 studies (eight prospective and 17 retrospective cohort studies) were eligible for analysis, including 40 920 women living with HIV. Preconception ART initiation was associated with a significantly increased risk of preterm birth (relative risk 1.16; 95% confidence interval [CI] 1.03–1.31) compared with antenatal ART initiation. Preconception ART initiation was not significantly associated with very preterm birth, low birthweight, very low birthweight, small for gestational age, very small for gestational age, or neonatal death. First trimester exposure (i.e. preconception or first trimester initiation) was not significantly associated with any increased risk of adverse perinatal outcomes. No significant association between timing of ART initiation and adverse perinatal outcomes was found in the studies of higher quality and those conducted in LMICs. Conclusion: Preconception ART initiation is associated with preterm birth but no other adverse perinatal outcomes. In LMICs, where most pregnant women living with HIV reside, the timing of ART initiation was not associated with any adverse perinatal outcomes. [ABSTRACT FROM AUTHOR]

Background: The global diversity of HIV forms a major challenge to the development of an HIV vaccine, as well as diagnostic, drug resistance, and viral load assays, which are essential to reaching the UNAIDS 90:90:90 targets. We sought to determine country-level HIV-1 diversity globally during 1990-2015.Methods: We assembled a global HIV-1 molecular epidemiology database through a systematic literature search and a global survey. We searched PubMed, EMBASE (Ovid), CINAHL (Ebscohost), and Global Health (Ovid) for HIV-1 subtyping studies published from Jan 1, 1990, to Dec 31, 2015. We collected additional unpublished data through a global survey of experts. Prevalence studies with original HIV-1 subtyping data collected during 1990-2015 were included. This resulted in a database with 383 519 subtyped HIV-1 samples from 116 countries over four time periods (1990-99, 2000-04, 2005-09 and 2010-15). We analysed country-specific numbers of distinct HIV-1 subtypes, circulating recombinant forms (CRFs), and unique recombinant forms (URFs) in each time period. We also analysed country-specific proportions of infections due to HIV-1 recombinants, CRFs, and URFs and calculated the Shannon Diversity Index for each country. Finally, we analysed global temporal trends in each of these measures of HIV-1 diversity.Results: We found extremely wide variation in complexity of country-level HIV diversity around the world. Central African countries such as Chad, Democratic Republic of the Congo, Angola and Republic of the Congo have the most diverse HIV epidemics. The number of distinct HIV-1 subtypes and recombinants was greatest in Western Europe (Spain and France) and North America (USA) (up to 39 distinct HIV-1 variants in Spain). The proportion of HIV-1 infections due to recombinants was highest in South-East Asia (>95% of infections in Viet Nam, Cambodia, and Thailand), China and West and Central Africa, mainly due to high proportions of CRF01_AE and CRF02_AG. Other CRFs played major roles (>75% of HIV-1 infections) in Estonia (CRF06_cpx), Iran (CRF35_AD), and Algeria (CRF06_cpx). The highest proportions of URFs (>30%) were found in Myanmar, Republic of the Congo and Argentina. Global temporal analysis showed consistent increases over time in country-level numbers of distinct HIV-1 variants and proportions of CRFs and URFs, leading to increases in country-level HIV-1 diversity.Conclusion: Our study provides epidemiological evidence that the HIV pandemic is diversifying at country-level and highlights the increasing challenge to prevention and treatment efforts. HIV-1 molecular epidemiological surveillance needs to be continued and improved.IMPORTANCE Global HIV diversity forms a major challenge to the development of an HIV vaccine, as well as diagnostic, drug resistance, and viral load assays, which are essential to reaching the UNAIDS 90:90:90 targets.

BACKGROUND: Global genetic diversity of HIV-1 is a major challenge to the development of HIV vaccines. We aimed to estimate the regional and global distribution of HIV-1 subtypes and recombinants during 1990-2015. METHODS: We searched PubMed, EMBASE (Ovid), CINAHL (Ebscohost), and Global Health (Ovid) for HIV-1 subtyping studies published between Jan 1, 1990, and Dec 31, 2015. We collected additional unpublished HIV-1 subtyping data through a global survey. We included prevalence studies with HIV-1 subtyping data collected during 1990-2015. We grouped countries into 14 regions and analysed data for four time periods (1990-99, 2000-04, 2005-09, and 2010-15). The distribution of HIV-1 subtypes, circulating recombinant forms (CRFs), and unique recombinant forms (URFs) in individual countries was weighted according to the UNAIDS estimates of the number of people living with HIV (PLHIV) in each country to generate regional and global estimates of HIV-1 diversity in each time period. The primary outcome was the number of samples designated as HIV-1 subtypes A, B, C, D, F, G, H, J, K, CRFs, and URFs. The systematic review is registered with PROSPERO, number CRD42017067164. FINDINGS: This systematic review and global survey yielded 2203 datasets with 383 519 samples from 116 countries in 1990-2015. Globally, subtype C accounted for 46·6% (16 280 897/34 921 639 of PLHIV) of all HIV-1 infections in 2010-15. Subtype B was responsible for 12·1% (4 235 299/34 921 639) of infections, followed by subtype A (10·3%; 3 587 003/34 921 639), CRF02_AG (7·7%; 2 705 110/34 921 639), CRF01_AE (5·3%; 1 840 982/34 921 639), subtype G (4·6%; 1 591 276/34 921 639), and subtype D (2·7%; 926 255/34 921 639). Subtypes F, H, J, and K combined accounted for 0·9% (311 332/34 921 639) of infections. Other CRFs accounted for 3·7% (1 309 082/34 921 639), bringing the proportion of all CRFs to 16·7% (5 844 113/34 921 639). URFs constituted 6·1% (2 134 405/34 921 639), resulting in recombinants accounting for 22·8% (7 978 517/34 921 639) of all global HIV-1 infections. The distribution of HIV-1 subtypes and recombinants changed over time in countries, regions, and globally. At a global level during 2005-15, subtype B increased, subtypes A and D were stable, and subtypes C and G and CRF02_AG decreased. CRF01_AE, other CRFs, and URFs increased, leading to a consistent increase in the global proportion of recombinants over time. INTERPRETATION: Global and regional HIV diversity is complex and evolving, and is a major challenge to HIV vaccine development. Surveillance of the global molecular epidemiology of HIV-1 remains crucial for the design, testing, and implementation of HIV vaccines.

Global HIV-1 genetic diversity forms a major obstacle to the development of an HIV vaccine. It may be necessary to employ subtype-specific HIV-1 vaccines in individual countries according to their HIV-1 subtype distribution. We estimated the global and regional need for subtype-specific HIV-1 vaccines. We took into account the proportions of different HIV-1 variants circulating in each country, the genetic composition of HIV-1 recombinants, and the different genome segments (gag , pol , env) that may be incorporated into vaccines. We modeled different scenarios according to whether countries would employ subtype-specific HIV-1 vaccines against (1) the most common subtype; (2) subtypes contributing more than 5% of HIV infections; or (3) all circulating subtypes. For therapeutic vaccines targeting the most common HIV-1 subtype in each country, 16.5 million doses of subtype C vaccine were estimated globally, followed by subtypes A (14.3 million) and B (4.2 million). A vaccine based on env required 2.6 million subtype E doses, and a vaccine based on pol required 4.8 million subtype G doses. For prophylactic vaccines targeting the most common HIV-1 subtype in each country, 1.9 billion doses of subtype A vaccine were estimated globally, followed by subtype C (1.1 billion) and subtype B (1.0 billion). A vaccine based on env required 1.2 billion subtype E doses, and a vaccine based on pol required 0.3 billion subtype G doses. If subtype-specific HIV-1 vaccines are also directed against less common subtypes in each country, vaccines targeting subtypes D, F, H, and K are also needed and would require up to five times more vaccine doses in total. We conclude that to provide global coverage, subtype-specific HIV-1 vaccines need to be directed against subtypes A, B, and C. Vaccines targeting env also need to include subtype E and those targeting pol need to include subtype G. [ABSTRACT FROM AUTHOR]

The global diversity of HIV forms a major challenge to the development of an HIV vaccine, as well as diagnostic, drug resistance, and viral load assays, which are essential to reaching the UNAIDS 90:90:90 targets. We sought to determine country level HIV-1 diversity globally between 1990 and 2015. We assembled a global HIV-1 molecular epidemiology database through a systematic literature search and a global survey. We searched PubMed, EMBASE (Ovid), CINAHL (Ebscohost), and Global Health (Ovid) for HIV-1 subtyping studies published from 1 January 1990 to 31 December 2015. We collected additional unpublished data through a global survey of experts. Prevalence studies with original HIV-1 subtyping data collected between 1990 and 2015 were included. This resulted in a database with 383,519 subtyped HIV-1 samples from 116 countries over four time periods (1990 to 1999, 2000 to 2004, 2005 to 2009, and 2010 to 2015). We analyzed country-specific numbers of distinct HIV-1 subtypes, circulating recombinant forms (CRFs), and unique recombinant forms (URFs) in each time period. We also analyzed country-specific proportions of infections due to HIV-1 recombinants, CRFs, and URFs and calculated the Shannon diversity index for each country. Finally, we analyzed global temporal trends in each of these measures of HIV-1 diversity. We found extremely wide variation in complexity of country level HIV diversity around the world. Central African countries such as Chad, Democratic Republic of the Congo, Angola, and Republic of the Congo have the most diverse HIV epidemics. The number of distinct HIV-1 subtypes and recombinants was greatest in Western Europe (Spain and France) and North America (United States) (up to 39 distinct HIV-1 variants in Spain). The proportion of HIV-1 infections due to recombinants was highest in Southeast Asia (-95% of infections in Viet Nam, Cambodia, and Thailand), China, and West and Central Africa, mainly due to high proportions of CRF01_AE and CRF02_AG. Other CRFs played major roles (-75% of HIV-1 infections) in Estonia (CRF06_cpx), Iran (CRF35_AD), and Algeria (CRF06_cpx). The highest proportions of URFs (-30%) were found in Myanmar, Republic of the Congo, and Argentina. Global temporal analysis showed consistent increases over time in country level numbers of distinct HIV-1 variants and proportions of CRFs and URFs, leading to increases in country level HIV-1 diversity. Our study provides epidemiological evidence that the HIV pandemic is diversifying at country level and highlights the increasing challenge to prevention and treatment efforts. HIV-1 molecular epidemiological surveillance needs to be continued and improved. [ABSTRACT FROM AUTHOR]

HTLV-I (Virus) ,Cytokines ,Cellular immunity - Abstract
This thesis presents studies on the interaction between the human T cell lymphotropic virus type 1 (HTLV-1) Tax protein and the 20S proteasome and the role of the interaction in cellular processes and the cytotoxic T cell (CTL) response against HTLV-1. The rapid translocation of Tax into the nucleus is described. Tax accumulates in the nucleus and forms unique bodies involved in transcriptional activation. It was further found that Tax associated with assembled nuclear 20S proteasomes and stimulated the chymotryptic and tryptic activities of the 20S proteasome, independent of the induction of the LMP2 and LMP7 proteasome subunits. Confocal microscopy revealed a partial colocalisation of Tax with nuclear proteasomes. A panel of Tax mutants was generated and their subcellular localisation and association with the 20S proteasome analysed. This analysis revealed that both the N- and C-terminus of Tax play a role in proteasome binding of Tax and further showed that proteasome binding was not sufficient for nuclear localisation of Tax. Therefore, Tax probably translocates into the nucleus prior to and independent of proteasome association. Tax specific CTL clones were generated and characterised using tetrameric MHC class I/peptide complexes. These CTL clones were used to investigate the requirements for processing and presentation of Tax for recognition by CTL. It was found that Tax was a metabolically very stable protein and that the presentation of the immunodominant Tax 11-19 epitope was dependent on the transporter associated with antigen presentation (TAP), independent of the expression of LMP2 and LMP7 proteasome subunits and resistant to treatment with the proteasome inhibitor lactacystin. It is proposed that the interaction between Tax and the 20S proteasome plays a role in Tax mediated transcriptional activation, leading to cellular activation and proliferation, and may not determine the immunodominance of Tax in the CTL response against HTLV-1.
