Epstein-Barr virus (EBV) is a B lymphotropic herpesvirus of humans that elicits strong HLA class I-restricted cytotoxic T lymphocyte (CTL) responses. An influence of such responses on virus evolution was first suggested by our finding that EBV isolates from the highly HLA A11-positive Papua New Guinea (PNG) population carried a lys-thr mutation at residue 424 of the nuclear antigen EBV-encoded ...

The hypothalamic A11 region has been identified in several species including rats, mice, cats, monkeys, zebrafish, and humans as the primary source of descending dopamine (DA) to the spinal cord. It has been implicated in the control of pain, modulation of the spinal locomotor network, restless leg syndrome, and cataplexy, yet the A11 cell group remains an understudied dopaminergic (DAergic) nu...

The saimiri transforming protein (STP) oncogene of Herpesvirus saimiri subgroup A strain 11 (STP-A11) is not required for viral replication but is required for lymphoid cell immortalization in culture and lymphoma induction in primates. We previously showed that STP-A11 interacts with cellular Src kinase through its SH2 binding motif and that this interaction elicits Src signal transduction. He...

HLA-A3 and -A11 share similar peptide-binding motifs, however, it is unclear if promiscuous epitope presentation by HLA-A3 or HLA-A11 is associated with promiscuous TCR recognition. Here, we show that despite widespread cross-presentation of identical HIV-1 peptides in HIV-1-infected individuals expressing HLA-A3 or HLA-A11, peptides presented by HLA-A3 or HLA-A11 commonly exhibited clear immun...

The presence of paranoid thoughts is not exclusive to clinical disorder; recent data suggest that their prevalence follows an exponential-shaped curve, with many people experiencing a few such thoughts, while a few people experience many such thoughts. Wong et al (pp. 221–229) found that this exponential curve was also evident in their assessment of paranoid thoughts in children, but the freque...

BACKGROUND The A11 diencephalospinal pathway is crucial for sensorimotor integration and pain control at the spinal cord level. When disrupted, it is thought to be involved in numerous painful conditions such as restless legs syndrome and migraine. Its anatomical organization, however, remains largely unknown in the non-human primate (NHP). We therefore characterized the anatomy of this pathway...

We examined whether herpes simplex virus thymidine kinase (HSV-TK) gene expression driven by the promoter of the vascular endothelial growth factor (VEGF) gene that is activated by hypoxia is effective in killing highly metastatic Lewis lung carcinoma A11 cells under hypoxic conditions. We isolated the promoter region encompassing the hypoxia response element (HRE) of the mouse VEGF gene. To as...

We examined whether herpes simplex virus thymidine kinase (HSVTK) gene expression driven by the promoter of the vascular endothelial growth factor (VEGF) gene that is activated by hypoxia is effective in killing highly metastatic Lewis lung carcinoma A11 cells under hypoxic conditions. We isolated the promoter region encompassing the hypoxia response element (HRE) of the mouse VEGF gene. To ass...

Recently, we demonstrated that S100C/A11 comprises an essential pathway for growth suppression by TGFbeta in normal human keratinocytes. Nuclear transfer of S100C/A11 was a hallmark of the activation of the process. In the present study, we examined the possible deterioration in the pathway in human squamous cancer cell lines, focusing on intracellular localization of S100C/A11 and its function...
