Skin is the first barrier of defense on fish, which is crucial to protection against different stressors, including pathogens. Skin samples obtained from dorsal and ventral part of Sparus aurata specimens were incubated with Photobacterium damselae subsp. piscicida (a pathogen for this fish species), with Shewanella putrefaciens Pdp11 (a probiotic bacteria isolated from healthy gilthead seabream skin) or with both bacteria. The gene expression profile of nine cytokines (il1b, tnfa, il6, il7, il8, il15, il18, il10 and tgfb) was studied by qPCR in all the skin samples. The present findings revealed different patterns of cytokine profile in dorsal and ventral skin of gilthead seabream, which could be related to the influence and susceptibility to a possible infection.

Abstract
Skin is the first barrier of defense on fish, which is crucial to protection against different stressors, including pathogens. Skin samples obtained from dorsal and ventral part of Sparus aurata specimens were incubated with Photobacterium damselae subsp. piscicida (a pathogen for this fish species), with Shewanella putrefaciens Pdp11 (a probiotic bacteria isolated from healthy gilthead seabream skin) or with both bacteria. The gene expression profile of nine cytokines (il1b, tnfa, il6, il7, il8, il15, il18, il10 and tgfb) was studied by qPCR in all the skin samples. The present findings revealed different patterns of cytokine profile in dorsal and ventral skin of gilthead seabream, which could be related to the influence and susceptibility to a possible infection.
