Poly(I:C), but not LPS, up‐regulates cytokine expression in neuron‐like SH‐SY5Y. SH‐SY5Y were treated with either LPS (100 ng/ml) or Poly(I:C) (50 μg/ml) for 24 hours followed by mRNA analysis in cell lysates and analysis of HMGB1 release in media using ELISA. (A) LPS had no detectable effect on expression of HMGB1, TNF‐α, IL‐1β, or IL‐6 mRNA. (B) LPS had no effect on HMGB1 release in media. (C) Poly(I:C) increased expression of HMGB1 (125%), TNF‐α (10,426%), IL‐1β (2,860%), and IL‐6 (591%) mRNA. (D) Poly(I:C) had no effect on HMGB1 release in media. Data for mRNA are expressed as %control (%CON), with CON set at 100%. n = 3 per group; n.d. = not detectable; *p < 0.05, **p < 0.01 versus CON.
