Overexpression of recombinant HIV-1 Subtype C Tat and Nef in a Salmonella vaccine vector
Tat and Nef are very important regulatory proteins of HIV-1. They enhance viral replication and down-regulate expression of MHC Class I molecules, respectively. The antigens are now considered to be targets for HIV vaccine development.

Signature molecules expressed differentially in a liver disease stage-specific manner by HIV-1 and HCV co-infection. [PDF]
To elucidate HIV-1 co-infection-induced acceleration of HCV liver disease and identify stage-specific molecular signatures, we applied a new high-resolution molecular screen, the Affymetrix GeneChip Human Transcriptome Array (HTA2.0), to HCV-mono- and ...

Plasma Membrane-Associated Restriction Factors and Their Counteraction by HIV-1 Accessory Proteins. [PDF]
The plasma membrane is a site of conflict between host defenses and many viruses. One aspect of this conflict is the host's attempt to eliminate infected cells using innate and adaptive cell-mediated immune mechanisms that recognize features of the ...

Human immunodeficiency virus‐1 Nef protein interacts with Tat and enhances HIV‐1 gene expression [PDF]
The human immunodeficiency virus (HIV‐1) Nef protein is now regarded as a regulatory protein responsible not only for establishment of infection and increased pathogenesis but also for enhancement of viral replication. However, the mechanism of Nef‐induced activation of viral replication remains to be clearly understood.

The Human Thioesterase II Protein Binds to a Site on HIV-1 Nef Critical for CD4 Down-regulation [PDF]
A HIV-1 Nef affinity column was used to purify a 35-kDa Nef-interacting protein from T-cell lysates. The 35-kDa protein was identified by peptide microsequence analysis as the human thioesterase II (hTE) enzyme, an enzyme previously identified in a yeast

Determinant of HIV-1 mutational escape from cytotoxic T lymphocytes. [PDF]
CD8+ class I-restricted cytotoxic T lymphocytes (CTLs) usually incompletely suppress HIV-1 in vivo, and while analogous partial suppression induces antiretroviral drug-resistance mutations, epitope escape mutations are inconsistently observed.

Fighting viral infections and virus-driven tumors with cytotoxic CD4+ T cells [PDF]
CD4+ T cells have been and are still largely regarded as the orchestrators of immune responses, being able to differentiate into distinct T helper cell populations based on differentiation signals, transcription factor expression, cytokine secretion, and

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.
