From: Glimepiride reduces CD14 expression and cytokine secretion from macrophages
Glimepiride releases CD14 from RAW 264 cells. (A) The amounts of CD14 in RAW 264 cells treated for one hour with control medium (□) or glimepiride (■) as shown. Values are means ± SD, from triplicate experiments performed 4 times, n = 12. (B) The amounts of CD14 in supernatants from RAW 264 cells treated for one hour with control medium (□) or glimepiride as shown (■). Values are means ± SD, from triplicate experiments performed 4 times, n = 12. (C) Immunoblots showing the amounts of CD14, PrPC, CD55 and caveolin in extracts from RAW 264 cells treated for 1 hour with control medium (i) or 5 μM glimepiride (ii). (D) The amounts of CD14 in cells (□) or supernatants (■) from microglial cells treated for 1 hour with control medium, 5 μM glimepiride or 5 μM glipizide. Values are mean units CD14 ± SD, from triplicate experiments performed 3 times, n = 9. *Cellular CD14 significantly less than control cells. **supernatant CD14 significantly greater than control supernatants. (E) Blot showing the amounts of CD14 in supernatants from microglial cells treated with concentrations of glimepiride as shown for one hour.
