Discordances between interpretation algorithms for genotypic resistance to protease and reverse transcriptase inhibitors of human immunodeficiency virus are subtype dependent (2006)

Kantor, Rami, Shafer, Robert W, Carvalho, Ana Patricia, ...

The major limitation of drug resistance genotyping for human immunodeficiency virus remains the interpretation of the results. We evaluated the concordance in predicting therapy response between four...

Impact of HIV-1 Subtype and Antiretroviral Therapy on Protease and Reverse Transcriptase Genotype: Results of a Global Collaboration (2005)

Rami Kantor, David A. Katzenstein, Brad Efron, Ana Patricia Carvalho, Brian Wynhoven, Patricia Cane, ...

Most research has focused on HIV-1 subtype B, although most infections worldwide are non-B. However, this paper suggests that the same drug resistance mutations occur across subtypes.

Impact of HIV-1 Subtype and Antiretroviral Therapy on Protease and Reverse Transcriptase Genotype: Results of a Global Collaboration (2005)

Rami Kantor, David A. Katzenstein, Brad Efron, Ana Patricia Carvalho, Brian Wynhoven, Patricia Cane, ...

Background The genetic differences among HIV-1 subtypes may be critical to clinical management and drug resistance surveillance as antiretroviral treatment is expanded to regions of the world where...

Cytotoxic T Cells from Human Immunodeficiency Virus Type 2-Infected Patients Frequently Cross-React with Different Human Immunodeficiency Virus Type 1 Clades

Bertoletti, Antonio, Cham, Fatim, McAdam, Stephen, Rostron, Tim, Rowland-Jones, Sarah, Sabally, Sehu, ...

Knowledge of immune mechanisms responsible for the cross-protection between highly divergent viruses such as human immunodeficiency virus type 1 (HIV-1) and HIV-2 may contribute to an understanding...

A Broad Range of Chemokine Receptors Are Used by Primary Isolates of Human Immunodeficiency Virus Type 2 as Coreceptors with CD4

McKnight, Áine, Dittmar, Matthias T., Moniz-Periera, José, Ariyoshi, Koya, Reeves, Jacqueline D., Hibbitts, Sam, ...

Like human immunodeficiency virus type 1 (HIV-1) and simian immunodeficiency virus (SIV), HIV-2 requires a coreceptor in addition to CD4 for entry into cells. HIV and SIV coreceptor molecules belong...

Mortality among Human Immunodeficiency Virus Type 2-Positive Villagers in Rural Guinea-Bissau Is Correlated with Viral Genotype

Grassly, Nicholas C., Xiang, Zheng, Ariyoshi, Koya, Aaby, Peter, Jensen, Henrik, ...

We present the results of a 6-year study of 131 human immunodeficiency virus (HIV) type 2 (HIV-2)-infected individuals from a rural population in Guinea-Bissau. Proviral DNA sequences 1.3 kb in...

Mutagenically Separated PCR Assay for Rapid Detection of M41L and K70R Zidovudine Resistance Mutations in CRF01_AE (Subtype E) Human Immunodeficiency Virus Type 1

Myint, Lay, Ariyoshi, Koya, Yan, Hua, Frater, Alexander J., Auwanit, Wattana, Pathipvanith, Panita, ...

A rapid zidovudine (ZDV) resistance genotypic assay was developed based on the mutagenically separated PCR (MS-PCR) technique to detect two ZDV-resistant mutations, M41L and K70R in CRF01_AE (subtype...
