Immuno-inflammatory Aspects of Interleukin-21 in Periodontal Sequelae: Current Development | Chapter 16 | Research Trends and Challenges in Medical Science Vol.2

Interleukin-21 (IL-21) has a dual anti-inflammatory and pro-inflammatory role in chronic inflammation. It causes breakdown of other surrounding hard and soft tissues by coupling with other destructive mediators, along with increasing several other proinflammatory cytokines. This chapter describes concepts in relation to effects of IL-21 on critical immune cells of both innate and adaptive immune systems, and how the cytokine evades its deactivation through a positive feedback loop. The chapter also reports results of an original study regarding quantification of IL-21 among types of periodontitis and comparing its levels to healthy subjects. Previous literature and our current study results suggest that IL-21 has a definite role in chronic and acute kind of inflammatory progression. Although, further longitudinal studies will strengthen its evidence to be characterized as a true diagnostic periodontal marker.
