Abstract:


Background: Inflammation is an innate immune response which is considered a common basis for several diseases such as ageing, diabetes, obesity, gout, neurodegenerative diseases and others. Among other platforms, inflammasomes are part of a superfamily of Pattern Recognition Receptors (PRR) and act as cytoplasmatic sensors for stimulation with Pathogen Associated Molecular Pattern (PAMPs) and/or Danger/Damage-Associated Molecular Patterns (DAMPs) leading to an infectious/ pathogenic or sterile inflammation. Inflammasomes constitute a complex platform with high molecular weight and functionality, divided into two families: NOD-like or NLR and PYHIN (pyrin and HIN200 - hematopoietic interferoninducible nuclear antigens). After activation by PAMPs or DAMPs, NLRP3 inflammasome promotes conversion of procaspase 1 in caspase-1 to form the active complex which is able to cleave pro-IL-1β and pro-IL-18 in respective active inflammatory cytokines IL-1β and IL-18 inducing cellular death by pyroptosis. Diabetes has a very intricate pathology with metabolic adaptation and inflammatory components apparently responsible for diabetic complications.

Objective: The present review evaluates the role of inflammasome, emphasizing NRLP3 on diabetes. An overview on several inflammatory diseases in which inflammasomes appear to play a role is included. Patents on inflammasomes associated with diabetes are evaluated and discussed.

Conclusion: There are a significant number of patents on inflammation but few of them are specifically on inflammasome and diabetes. The patents WO2015003246; US20130273588; WO2012016145; and CN104258398 are shown and their mechanisms are discussed. In conclusion, deeply studies on inflammasomes mechanisms will help the proposition of new therapeutic targets for controlling inflammatory process in diabetic complications.
