Recognition of a novel stage of betaherpesvirus latency in human herpesvirus 6

Latency-associated transcripts of human herpesvirus 6 (H6LTs) (K. Kondo et al. J. Virol. 76:4145-4151, 2002) were maximally expressed at a fairly stable intermediate stage between latency and reactivation both in vivo and in vitro. H6LTs functioned...

ARF6 stimulates clathrin/AP-2 recruitment to synaptic membranes by activating phosphatidylinositol phosphate kinase type I gamma

Clathrin-mediated endocytosis of synaptic vesicle membranes involves the recruitment of clathrin and AP-2 adaptor complexes to the presynaptic plasma membrane. Phosphoinositides have been implicated in nucleating coat assembly by directly binding to...

Histamine enhances TGF-beta1-mediated suppression of TH2 responses

Susceptibility of T cells to TGF-beta1 produced by regulatory T cells has an important impact on the induction and maintenance of peripheral tolerance and therefore on the development of autoimmunity, cancer, and allergy. Histamine not only mediates...

SARA and Hgs attenuate susceptibility to TGF-beta1-mediated T cell supression

Transforming growth factor-beta1 (TGF-beta1) is a pluripotent cytokine that controls peripheral T cell tolerance mainly in mucosal immunity. It is secreted by regulatory T cells (Tr /Th3) but also by other immununologically active cells. Smad anchor...

IL-10-inducible Bcl-3 negatively regulates LPS-induced TNF-alpha production in macrophages

Interleukin-10 (IL-10) plays an important role in prevention of chronic inflammation in vivo. However, the molecular mechanism by which IL-10 exerts its anti-inflammatory response is poorly understood. Here, we performed a microarray analysis and...

Nucleoporation of dendritic cells: efficient gene transfer by electroporation into human monocyte-derived dendritic cells

Dendritic cells (DCs) are ideal accessory cells in the developing field of gene therapy. Although viral transfection of DCs has become widespread, non-viral transfection of DCs has shown disappointing results. Recently, a new technique for...

Inhibition of constitutive NF-kappaB activation in mantle cell lymphoma B cell lead to induction of cell cycle arrest and apoptosis

Constitutive activation of the NF-kappaB has been documented to be involved in the pathogenesis of many human malignancies, including hemopoietic neoplasms. In this study, we examined the status of NF-kappaB in two non-Hodgkin's lymphoma cell lines...

Proteasome inhibition results in TRAIL sensitization of primary keratinocytes by removing the restistance-mediating block of effector caspase maturation

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) exerts potent cytotoxic activity against transformed keratinocytes, whereas primary keratinocytes are relatively resistant. In several cell types, inhibition of the proteasome sensitizes...

The immunosuppressant rapamycin represses human immunodeficiency virus type 1 replication

The immunosuppressive macrolide rapamycin is used in humans to prevent graft rejection. This drug acts by selectively repressing the translation of proteins that are encoded by an mRNA bearing a 5'-polypyrimidine tract (e.g., ribosomal proteins,...

BPAG1n4 is essential for retrograde axonal transport in sensory neurons

Disruption of the BPAG1 (bullous pemphigoid antigen 1) gene results in progressive deterioration in motor function and devastating sensory neurodegeneration in the null mice. We have previously demonstrated that BPAG1n1 and BPAG1n3 play important...
