Deregulation of cytokine affecting oral neutrophil subsets in oral cancer

AbstractThe most prevalent form of leukocytes in human blood, neutrophils, is regarded as an essential part of the innate immune system and the body ’s 1st line of defense against foreign invaders. However, divergent opinions arise on the role of neutrophils in cancer, likely due to the occurrence of many neutrophil subsets. Several factors in the tumor microenvironment were found to modify the phenotype and function of neutrophils. Inhibitory cytokine production and recruitment of protumor immune cells to the tumor microenvironment are the reasons for immune suppression. Although some salivary cytokines were found to be increased in cancer patient’s saliva, simultaneously, it was observed that those cytokines are high in other oral in flammatory conditions. So, it is challenging to distinguish at what level of expression those cytokines are involved in the neoplastic process. Therefore, the goal of this study is to provide a summary of the current information about the existence and presence of specific cytokines that impact cPMN and TAN and their potential activities in the context of healthy and cancer states so that we can relate to oPMN.
