Forced expression of the Fc Receptor gamma-chain renders human T cells hyperresponsive to TCR/CD3 stimulation

High level expression of Fc epsilon RI gamma chain replaces the deficient TCR zeta-chain and contributes to altered TCR/CD3-mediated signaling abnormalities in T cells of patients with systemic lupus erythematosus. Increased responsiveness to Ag has...

Amyloid precursor protein mediates proinflammatory activation of monocytic lineage cells

Alzheimer's disease is a progressive neurodegenerative disorder characterized by extracellular deposition of beta-amyloid (Abeta) peptide containing neuritic plaques. Abeta peptides are proteolytically derived from the membrane-bound amyloid...

ERK 1/2 and JNKs-dependent synthesis of IL-6 and IL-8 by fibroblast-like synoviocytes stimulated with protein I/II, a modulin from oral streptococci, requires FAK

Protein I/II, a pathogen-associated molecular pattern from oral streptococci, is a potent inducer of interleukin-6 (IL-6) and IL-8 synthesis and release from fibroblast-like synoviocytes (FLSs), cells that are critically involved in joint...

FAS (CD95) mutations are rare in gastric MALT lymphoma but occur more frequently in primary gastric diffuse large B-cell lymphoma

A loss of FAS (CD95) function has been proposed to constitute an important step in early mucosa-associated lymphoid tissue (MALT) lymphoma development and FAS mutations have been recognized in malignant lymphomas, in particular at extranodal sites....

Epstein-Barr virus LMP1 blocks p16INK4a-RB pathway by promoting nuclear export of E2F4/5

The p16INK4a-RB pathway plays a critical role in preventing inappropriate cell proliferation and is often targeted by viral oncoproteins during immortalization. Latent membrane protein 1 (LMP1) of Epstein-Barr virus (EBV) is often present in...

Bucillamine induces the synthesis of vascular endothelial growth factor dose-dependently in systemic sclerosis fibroblasts via nuclear factor-B and simian virus 40 promoter factor 1 pathways

The pathogenesis of systemic sclerosis (SSc) is characterized by activation of the immune system, impaired angiogenesis, and activated dermal fibroblasts. The effects of the immunosuppressive agent bucillamine (SA 96) on fibroblasts and angiogenic...

A serine protease inhibitor prevents endoplasmic reticulum stress-induced cleavage but not transport of the membrane-bound transcription factor ATF6

Mammalian cells express several transcription factors embedded in the endoplasmic reticulum (ER) as transmembrane proteins that are activated by proteolysis, and two types of these proteins have been extensively investigated. One type comprises the...

Toll-like receptor signaling alters the expression of regulator of g protein signaling proteins in dendritic cells: implications for g protein-coupled receptor signaling

Conserved structural motifs on pathogens trigger pattern recognition receptors present on APCs such as dendritic cells (DCs). An important class of such receptors is the Toll-like receptors (TLRs). TLR signaling triggers a cascade of events in DCs...

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...

Cutting Edge: TGF-beta Induces a Regulatory Phenotype in CD4(+)CD25(-) T Cells through Foxp3 Induction and Down-Regulation of Smad7

CD4(+)CD25(+) regulatory cells are a subpopulation of T lymphocytes of thymic origin. However, recent data suggest an alternative commitment of regulatory T cells in the periphery, although the precise mechanism is unknown. In the present work, we...
