Correction: The ATP Receptors P2X7 and P2X4 Modulate High Glucose and Palmitate-Induced Inflammatory Responses in Endothelial Cells.

There is an error in panel B of Fig 4. Please view Fig 4 here.

Fig 4

Purinergic modulation of high glucose and palmitate-induced IL-6, IL-8 and COX-2 protein.

HUVECs were exposed to high glucose and palmitate (48 h) in the presence or absence of the P2X7 and P2X4 antagonists. The supernatants were analyzed for IL-6 (A) and IL-8 (B) secretion using ELISA. Cell lysates probed for COX-2 (C; 74 kDa) and normalized to β-Tubulin are represented as percentage of control. A representative immunoblot for each protein is depicted. n = 3 to 4 independent experiments each done in replicates; *p ≤ 0.05.
