siRNA knockdown of HA receptors in Kupffer cells from pair- and ethanol-fed rats. Wistar rats were allowed free access to a Lieber-DeCarli ethanol diet or pair-fed control diet for 4 weeks. Kupffer cells were isolated and nucleofected with 25 nM of scrambled siRNA or siRNA targeted to (A) TLR4, (B) TLR2, (C) RHAMM and (D) CD44. 24 h post-nucleofection, expression of (A) TLR4 (green), (B) TLR2 (red), (C) RHAMM (red) and (D) CD44 (red) was visualized by immunostaining with specific antibodies. Nuclei were labelled with DAPI (blue). All images were acquired using 20x objectives and are representative of 3 independent experiments.
