Interleukin-1 receptor antagonist in normal and psoriatic epidermis.
The objective of these studies was to characterize the IL-1 inhibitory activity present in normal and psoriatic epidermis from clinically stable lesions. Fractionation of normal epidermal cytosol on a molecular sizing column failed to reveal the presence of IL-1 inhibitory bioactivity. However, specific ELISAs indicated that both the IL-1 receptor antagonist (IL-1ra) and IL-1 alpha were present...
متن کاملIn Vitro Cell Cycle Synchronization of Sheep Granulosa Cells
Purpose: To investigate the effect of different methods of synchronization on sheep granulosa cell cycle. Materials and Methods: Granulosa cells were aspirated from ovarian follicles and plated in a DMEM medium containing 15% FBS. Upon 70-80% confluency, the medium of the primarycultured as well as the passaged-5 cells were replaced with the medium containing either 0.5% FBS for 24, 48 and 72 h...

Altered Levels of Sphingosine and Sphinganine in Psoriatic Epidermis
BACKGROUND Ceramides are the main lipid component of the stratum corneum and are a structurally heterogeneous and complex group of sphingolipids of which sphingoid bases are the basic structural constituents. Altered levels of sphingoid bases have been reported in skin conditions that involve dryness and barrier disruption, including atopic dermatitis. OBJECTIVE The purpose of this study was ...
متن کاملCeramides and Cell Signaling Molecules in Psoriatic Epidermis: Reduced Levels of Ceramides, PKC-α, and JNK
Ceramides are the main lipids in the stratum corneum and are generated during cellular stress and apoptosis by de novo synthesis or by the action of sphingomyelinase. In addition, they are lipid second messengers produced by sphingolipid metabolism and trigger important cell responses, including protein kinase C-alpha (PKC-alpha) activation and the stimulation of signal transduction pathways wi...
