Today, we want to draw your attention to an open-access review that focuses on the role of senescent cells in sarcopenia, the age-related loss of muscle mass and strength that leads to frailty. Aging is the prime risk factor for the broad-based development of diseases. Frailty is a phenotypical hallmark of aging and is often…

Today we are going to take a look at the emerging theory that inflammaging, a chronic, age-related background of inflammation, is caused by alterations to the populations of intestinal microbes. What is inflammaging? Inflammaging is a term coined to describe the chronic, smoldering background of inflammation that accompanies the aging process. It is constant, low-grade…

Elena Milova is at the Interventions to extend healthspan and lifespan 2018 conference in Kazan this week. This is an important conference in the aging research field, and it includes a variety of leading experts giving talks about their research. One of these experts is Dr. Andrei Gudkov, and Elena had the opportunity to talk…

Today we will be looking at new research that may provide a new treatment option for those suffering from chronic obstructive pulmonary disease. What is Chronic obstructive pulmonary disease? Chronic obstructive pulmonary disease, or COPD, is a progressive respiratory disease characterized by shortness of breath and cough with sputum production. It generally takes a long time to…

The aging process is 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. Today, we are going to take a look at inflammaging and the various known sources that promote this age-related inflammatory…

Nicotinamide adenine dinucleotide (NAD+), a nucleotide, is critical for life to exist. From the most simple bacteria to complex multicellular organisms such as humans, NAD is a vital component of cellular function and thus life. An increased level of NAD+ appears to convey health and longevity, and a decrease is associated with aging and disease….

We have talked about the polarization of macrophages in a number of previous articles, but, in short, macrophages can have multiple behavioral profiles that determine what roles they play; this is known as polarization. A new study has identified a regulatory protein that controls this process. Macrophage Polarization For the purposes of this article, we…

In a new study, researchers propose that TIGIT is a marker of T cell senescence and exhaustion in the immune system[1]. However, not only is TIGIT just a biomarker, it is also a potential therapeutic target; as the researcher team discovered, lowering levels of TIGIT resulted in the restoration of some lost function in T…

Researchers at Linköping University in Sweden have discovered a new kind of warning system that plays a role in the immune system. Mitochondria in the white blood cells produce a web of DNA fibers that act as a kind of alarm. The Mitochondrial web slinger White blood cells (leukocytes) are a primary part of our…

The search for accurate ways to measure biological age is an ongoing quest in aging research. It is important for academia to reach a consensus on robust, cost-effective, and reliable biomarkers of aging in order for the field to progress. Currently, there is a lack of reliable and fast ways to assess biological age and…
