| Abstract |
OBJECTIVES:Choroid plexus (CP) epithelial cells have multiple functions in the cerebral ventricles, including cerebrospinal fluid (CSF) production and forming part of the blood-CSF barrier. They are also responsible for producing inflammatory mediators involved in meningitis. The present study aimed to elucidate the functions of the CP epithelial cells during CNS inflammation. MATERIALS AND METHODS:We analyzed the proteome and phosphoproteome in lipid A-treated ECPC-4 mouse CP cells by gel electrophoresis and mass spectrometry. RESULTS:Levels of 10 proteins and seven phosphoproteins were significantly altered by lipid A in time-dependent manners, including V-type proton ATPase subunit B (ATP6V), protein 40 kD, elongation factor-1δ, coatomer subunit ε (COPE), vimentin (isoform CRA a), purine nucleoside phosphorylase, eukaryotic initiation factor-4F splicing variant, put. β-actin, peroxiredoxin-6 isoform 1, and immunoglobulin heavy chain variable region. These proteins could be classified as having cytoskeleton/intermediate filament, protein-folding, signal-transduction, cell-growth, metabolism, and redox-regulation functions. The identified phosphoproteins were HSP 84, γ-actin, HSP 70 cognate, vimentin, tubulin β-4B chain, protein disulfide-isomerase A6 precursor, and heterogenous nuclear ribonucleoprotein, which could be classified as having cytoskeleton/intermediate filament, protein-folding, and metabolism functions. CONCLUSIONS:These results indicate that lipid A can change the levels of proteins and phosphoproteins in ECPC-4 cells, suggesting that the identified proteins and phosphoproteins may play important roles in inflammation of the CP. |
