Protein kinase D1: a new component in TLR9 signaling.
Protein kinase D1 (PKD1) is expressed ubiquitously and regulates diverse cellular processes such as oxidative stress, gene expression, cell survival, and vesicle trafficking. However, the presence and function of PKD1 in monocytic cells are currently unknown. In this study, we provide evidence that PKD1 is involved in TLR9 signaling in macrophages. Class B-type CpG DNA (CpG-B DNA) induced activ...
متن کاملTLR9 signaling defines distinct prognostic subsets in CLL.
Chronic lymphocytic leukemia (CLL) is a common B-cell malignancy characterized by a highly variable clinical course. The behavior of the disease is believed to be influenced by microenvironmental signals that regulate the proliferation and survival of the malignant B-cells. Signals transduced through Toll-like-receptor-9 (TLR9) may play a particularly important role, as they could drive the exp...
متن کاملRole of TI-VAMP and CD82 in EGFR cell-surface dynamics and signaling.
The v-SNARE TI-VAMP (VAMP7) mediates exocytosis during neuritogenesis, phagocytosis and lysosomal secretion. It localizes to endosomes and lysosomes but also to the trans-Golgi network. Here we show that depletion of TI-VAMP enhances the endocytosis of activated EGF receptor (EGFR) without affecting constitutive endocytosis of EGFR, or transferrin uptake. This increased EGFR internalization is ...
متن کاملSynthetic Human TLR9-LRR11 Peptide Attenuates TLR9 Signaling by Binding to and thus Decreasing Internalization of CpG Oligodeoxynucleotides.
Toll-like receptor (TLR) 9 is an endosomal receptor recognizing bacterial DNA/CpG-containing oligodeoxynucleotides (CpG ODN). Blocking CpG ODN/TLR9 activity represents a strategy for therapeutic prevention of immune system overactivation. Herein, we report that a synthetic peptide (SP) representing the leucine-rich repeat 11 subdomain of the human TLR9 extracellular domain could attenuate CpG O...
متن کاملAttenuation of EGF receptor signaling by a metastasis suppressor, the tetraspanin CD82/KAI-1
The 'metastasis suppressor' CD82/KAI-1, a member of the tetraspanin superfamily of transmembrane proteins, is widely distributed in normal tissues [1], and has been shown to be suppressed in the advanced stages of various epithelial malignancies [2-6]. Although the physiological relevance of this change is unknown, in vitro data show that ectopically expressed CD82/KAI-1 can suppress tumor cell...
