چکیده انگلیسی
In the present study, we found that recombinant grass carp IL-1β (rgcIL-1β) simultaneously up-regulated grass carp IL-1β (gcIL-1β) and TGF-β1 (gcTGF-β1) expression via NF-κB and MAPK signaling in grass carp head kidney leukocytes (HKLs), promoting us to clarify whether TGF-β1 is an effective antagonist in IL-1β expression and activity. Our results showed that a stimulation of gcIL-1β on its own expression was noted within 6âh, but gcTGF-β1 neutralizing antibody prolonged gcIL-1β autostimulation up to 12âh, indicating a possible inhibitory role of gcTGF-β1 in regulating gcIL-1β effect. This notion was reinforced by the fact that recombinant grass carp TGF-β1 (rgcTGF-β1) could impede rgcIL-1β-induced gcIL-1β gene expression and secretion in a reciprocal manner. Further studies revealed that rgcTGF-β1 was able to attenuate rgcIL-1β-induced mRNA expression of its own receptor signaling molecules and the activation of NF-κB. By contrast, rgcIL-1β significantly amplified rgcTGF-β1-mediated gcTGF-β1 type I receptor (ALK5) expression and Smad2 phosphorylation in the same cell model. Taken together, these data shed light on an intrinsic mechanism for controlling inflammatory response by the reciprocal interaction between TGF-β1 and IL-1β in teleost.
