Allergic diseases are hypersensitivity disorders that are associated with the generation of specific immunoglobulin E (IgE) in response to environmental allergens. Interleukin (IL)-4, which is primarily produced by the CD4(+) T cells, is an important stimulus for the switching of
Cells release extracellular vesicles (EVs) in their environment and cellular lipids play an important role in their formation, secretion and uptake. Besides, there is also evidence that EV transferred lipids impact on recipient's cell signaling. Cellular senescence is characterized by

The specific activity of acid ceramidase (N-acylsphingosine deacylase, EC 3.5.1.23) was measured at pH4.5 in normal fibroblasts and in fibroblasts from patients with Farber disease and obligate heterozygotes. Greater activity was found when the synthetically made ceramide substrates contained shorter-chain

Hepatic stellate cells (HSCs) are non-parenchymal liver cells that characteristically contain multiple retinoid (vitamin A)-containing lipid droplets. In this study, we addressed the metabolic fate of non-retinoid lipids originating from lipid droplet loss during HSCs activation. UPLC/MS/MS and qRT-PCR were
Journal of lipid research, 38(12), 2569-2579 (1998-02-11)
De novo synthesis and turnover of endogenous ceramide in cultured skin fibroblasts from patients affected with Farber lipogranulomatosis were studied by biosynthetical labeling of cellular sphingolipids with [14C]serine. The cellular uptake of [14C]serine and incorporation into de novo synthesized ceramide
