The inflammatory pattern during Helicobacter pylori(***)infection is changeable and *** childhood,it is possible to observe a predominantly regulatory response,evidenced by high concentrations of key cytokines for the maintenance of Treg responses such as TGF-β1 and IL-10,in addition to high expression of the transcription factor *** the other hand,there is a predominance of cytokines associated with the Th1 and Th17 responses among ***-positive *** the last few years,the participation of the Th17 response in the gastric inflammation against *** infection has been highlighted due to the high levels of TGF-β1 and IL-17 found in this infectious scenario,and growing evidence has supported a close relationship between this immune response profile and unfavorable outcomes related to the ***,this cytokine profile might play a pivotal role in the effectiveness of *** *** is evident that age is one of the main factors influencing the gastric inflammatory pattern during the infection with ***,and understanding the immune response against the bacterium can assist in the development of alternative prophylactic and therapeutic strategies against the infection as well as in the comprehension of the pathogenesis of the outcomes related to that microorganism.
