Abstract BACKGROUND: Mutations of NFkB1 are a known cause inborn errors immunity resulting in immunodeficiency due to the role as transcriptional regulator immunomodulating proteins. We present patient with diagnosis common variable (CVID), cytopenias massive splenomegaly, and nodular regenerative hyperplasia liver. Our proband, 22-year-old male, presents clinical picture immunodeficiency, has ...

introduction: human t cell lymphotropic l.irus type i is responsible for adult t cell leukemia/lymphoma and htlv-i associated myelopathy. the aim of this study was constructing two reporter plasmids to enable us to evaluate the effects of htlv-i tax protein upon intra cellular signalling pathways which recruit creb and nfkb proteins. material and methods: a complete coding region of bacterial b...

The recurrence of prostate cancer metastases to bone after androgen deprivation therapy is a major clinical challenge. We identified FN14 (TNFRSF12A), a TNF receptor family member, as a factor that promotes prostate cancer bonemetastasis. In experimental models, depletion of FN14 inhibited bonemetastasis, and FN14 could be functionally reconstituted with IKKb-dependent, NFkB signaling activatio...

PURPOSE The retinal pigment epithelium (RPE) is a major source of vascular endothelial growth factor (VEGF) in the eye. Despite the role of VEGF in ocular pathology, VEGF is an important factor in maintaining the choroid and the RPE. Accordingly, the VEGF is constitutively expressed in RPE. In this study, the regulation of constitutive VEGF expression was investigated in an RPE/choroid organ cu...

The role of ceramide as a second messenger in tumor necrosis factor (TNF)-mediated signal transduction has been much debated. It is supported by recent reports describing an expanding number of potential targets for this lipid, but is opposed by those describing how ceramide is not necessary for many TNF-mediated cellular events. In this paper, we directly compare the effects of the cell-permea...

BACKGROUND Helicobacter pylori elicited IL1B is one of the various modulators responsible for perturbation of acid secretion in gut. We have earlier reported that IL1B activated NFkB downregulates gastrin, a major modulator of acid secretion. However, we hypothesized that regulation of gastrin by IL1B would depend on the cell's ability to integrate inputs from multiple signaling pathways to gen...
