What is Inflammaging? Chronic Inflammation and Aging

What is inflammaging? The aging processes are accompanied by a chronic, smoldering background of inflammation that researchers call “inflammaging”. This backdrop of low-grade inflammation contributes significantly to mortality risk in the elderly and has a number of sources. The chronic inflammation that accompanies the aging process is believed to be a significant risk factor for a myriad of age-related diseases, such as atherosclerosis, arthritis, hypertension, and cancer [1-3]. The immune system relies on acute inflammation during the immune response to fight invading pathogens and to facilitate wound healing. This triggers cell turnover and tissue repair and is, in general, a desirable reason for inflammation. However, in direct contrast to this, inflammaging produces a chronic, low-grade, persistent background of inflammation that leads to poor tissue repair and degeneration [4]. This chronic inflammation also contributes to the development of age-related diseases and is instrumen...

What Is Metformin and Why Do People Take It?

Metformin is widely prescribed for type 2 diabetes; it improves glucose metabolism and thereby reduces diabetic complications. How it works is not well-understood, but we know that metformin mostly interacts with signaling molecules in the liver, gut, and kidney. Results vary according to the dosage and duration of metformin treatment. Metformin has multiple mechanisms of action, which likely account for its anticystic, antitumor, cardioprotective, neuroprotective, and longevity effects. Metformin and glucose metabolism Diabetes is an age accelerator. Compared to non-diabetic individuals, the phenotypic age (PhAge) of individuals with type 1 and type 2 diabetes is 12.02 and 16.32 years higher, respectively [1]. Metformin helps normalize glucose levels and therefore may slow changes in PhAge. Metformin’s journey in the body begins with gut cells called enterocytes. Metformin carries a positive charge, which makes it relatively easy to cross the negatively charged cell membrane. Further,...
