IL-6 is not required for the reconsolidation of fear memory. a Study design. b Plasma levels of IL-6 in fear-conditioned mice re-exposed to 0 (No CS) or 1 CS. c Conditioned freezing in response to 1 CS in WT and IL-6−/− mice. d Conditioned freezing of WT and IL-6−/− mice in response to each of 4 CS presented 24 hours after initial re-exposure. e Conditioned freezing averaged across 4 CS re-exposures during test. f Conditioned freezing in response to 1 CS re-exposure in ControlAb- and IL6Ab-treated mice. g Maintenance of fear memory in ControlAb-and IL6Ab-treated mice during each of 4 CS in a test of reconsolidation h and averaged across 4 CS.
