The BDNF receptor, TrkB, is critical to limbic epileptogenesis, but the responsible downstream signaling pathways are unknown. We hypothesized that TrkB-dependent activation of phospholipase Cgamma1 (PLCgamma1) signaling is the key pathway and tested this in trkB(PLC/PLC) mice carrying a mutation (Y816F) that uncouples TrkB from PLCgamma1. Biochemical measures revealed activation of both TrkB a...

Signaling from G protein-coupled receptors to phospholipase C-beta (PLC-beta) is regulated by coordinate interactions among multiple intracellular signaling molecules. Phosphatidic acid (PA), a signaling phospholipid, binds to and stimulates PLC-beta(1) through a mechanism that requires the PLC-beta(1) C-terminal domain. PA also modulates Galpha(q) stimulation of PLC-beta(1). These data suggest...

Vasoconstrictors activate phospholipase C (PLC), which hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP(2)), leading to calcium mobilization, protein kinase C activation, and contraction. Our aim was to investigate whether PLC-delta(1), a PLC isoform implicated in alpha(1)-adrenoreceptor signaling and the pathogenesis of hypertension, is involved in noradrenaline (NA) or endothelin (ET-1)-...

Based on the research ideological and political education in course "Machine Tool Electrical PLC", this article explores how to integrate into machine tool electrical PLC course. By analyzing characteristics of PLC" advantages integrating it education, corresponding improvement measures are proposed provide useful reference for higher teaching practice.

Apoptosis is a cell suicide mechanism that requires the activation of cellular death proteases for its induction. We examined whether the progress of apoptosis involves cleavage of phospholipase C-gamma1 (PLC-gamma1), which plays a pivotal role in mitogenic signaling pathway. Pretreatment of T leukemic Molt-4 cells with PLC inhibitors such as U-73122 or ET-18-OCH(3) potentiated etoposide-induce...

The genome of Mycobacterium tuberculosis H37Rv contains three contiguous genes (plc-a, plc-b and plc-c) which are similar to the Pseudomonas aeruginosa phospholipase C (PLC) genes. Expression of mycobacterial PLC-a and PLC-b in E. coli and M. smegmatis has been reported, whereas expression of the native proteins in M. tuberculosis H37Rv has not been demonstrated. The objective of the present st...

The physiological roles of phospholipase C (PLC) beta2 in hematopoiesis, leukocyte function, and host defense against infection were investigated using a mouse line that lacks PLC beta2. PLC beta2 deficiency did not affect hematopoiesis, but it blocked chemoattractant-induced Ca2+ release, superoxide production, and MAC-1 up-regulation in neutrophils. In view of these effects, it was surprising...

This paper provides discussion of security issues for power line networks (PLC). The home network based on power line communication has been used widely however security of PLC has not been discussed sufficiently. Though PLC uses power line as medium it has similar characterises with wireless communications in the view of security. The authentication and cryptographic scheme used in PLC standar...
