Inhibition of neutral sphingomyelinase protects mice against systemic tuberculosis.
Tuberculosis is one of the most serious infectious diseases worldwide. The initial pulmonal localization of the pathogens often develops into systemic infection with high lethality. We investigated the role of the mammalian neutral sphingomyelinase (Nsm)/ceramide system in systemic infection of mice and murine macrophages with Mycobacterium bovis Bacillus Calmette-Guerin (BCG). Our results demo...
متن کاملNeutral sphingomyelinase 2 (nSMase2) is the primary neutral sphingomyelinase isoform activated by tumour necrosis factor-α in MCF-7 cells.
Activation of N-SMase (neutral sphingomyelinase) is an established part of the response of cytokines such as TNF (tumour necrosis factor)-α. However, it remains unclear which of the currently cloned N-SMase isoforms (nSMase1, nSMase2 and nSMase3) are responsible for this activity. In MCF-7 cells, we found that TNF-α induces late, but not early, increases in N-SMase activity, and that nSMase2 is...
متن کاملNeutral sphingomyelinase-2, acid sphingomyelinase, and ceramide levels in COPD patients compared to controls
BACKGROUND Increased pulmonary ceramide levels are suggested to play a causative role in lung diseases including COPD. Neutral sphingomyelinase-2 (nSMase-2) and acid SMase (aSMase), which hydrolyze sphingomyelin to produce ceramide, are activated by a range of cellular stresses, including inflammatory cytokines and pathogens, but notably cigarette smoke appears to only activate nSMase-2. Our pr...
متن کاملTranscription factor 7 like 2 promotes oligodendrocyte differentiation and remyelination
Transcription factor 7 like 2 (TCF7L2, also termed TCF4), is a Wnt effector induced transiently in the oligodendroglial lineage. The current well accepted hypothesis is that TCF7L2 inhibits oligodendrocyte differentiation and remyelination through canonical Wnt/β‑catenin signaling. However, recent studies indicated that TCF7L2 activity is required during oligodendrocyte differentiation and remy...
متن کاملInhibition of neutral sphingomyelinase decreases arachidonic acid mediated inflammation in liver ischemia-reperfusion injury.
This study aimed to determine the role of selective neutral sphingomyelinase (N-SMase) inhibition on arachidonic acid (AA) mediated inflammation following liver ischemia-reperfusion (IR) injury. Selective N-SMase inhibitor was administered via intraperitoneal injections. Liver IR injury was created by clamping blood vessels supplying the median and left lateral hepatic lobes for 60 min, followe...
