Lipopolysaccharide and flagellin were shown to stimulate ERK activation in chicken heterophils.

Bioinformatic analysis reveals no evidence of ERK1 in the chicken genome, although chicken orthologs to other mediators of MEK-ERK signaling (MEK1, MEK2, ERK2 etc.) were identified. In this Reactome model we show ERK2 activation and assume that chicken MEK-ERK mediators behave like their human counterparts.
