Figure 1. The hallmarks of ageing (Source: [55]) The well-established nine hallmarks of aging include: [55] Genomic instability Shortening telomere length Epigenetic modifications Loss of proteostasis Video 2 ( 32:12 ) Deregulated nutrient sensing Mitochondrial dysfunction SIRT3 , an important stress-responsive deacetylase with cardio-protective and longevity enhancing properties involved in mitochondrial homeostasis , stem cells and tissue maintenance. [56,57] Cellular senescence Stem cell exhaustion Altered intracellular communication  (Video 2) have all been shown to be caused, at least in part, by sustained systemic inflammation . [45-54] Video 1. Can ageing be delayed, stopped or even reversed? BBC News (YouTube link ) Inflammatory Clock (or iAge) Inflammation plays a role in almost all chronic diseases of ageing including atherosclerosis, cancer, neurodegenerative diseases and diabetes. From the blood immunome of 1,001 individuals aged 8–96 years, Sayed et al. developed ...

Melatonin’s role in immunomodulation remains under investigation; its use for autoimmune or inflammatory disorders should be undertaken only under specialist supervision. Both Treg dysfunction and hyperactive responder T-cell proliferation contribute to disease. In this article, we will discuss the importance of regulating between Th17 and Treg cells. F igure 1.    IL‐6   mediates Th17 / Treg balance. IL‐6 induces Th17 differentiation from naïve T cells together with TGF‐β . On the other hand, IL‐6 inhibits Treg differentiation induced by TGF‐β . IL-6: Regulator of Treg/Th17 Balance Inflammatory T cells are thought to be central to the pathology of autoimmune diseases . Especially, the recently identified T‐cell subset, the  Th17  cells, shows pro‐inflammatory functions and plays a critical role in various autoimmune disorders. Recent studies have de...
