The researchers believe that increasing calcium uptake by the mitochondrial macrophages could prevent the inflammation and its terrible effects. UVA Health researchers, led by Bimal N.

Desai, found that mitochondria in immune cells lose their ability to take up and use calcium, leading to chronic inflammation responsible for many of the age-related ailments.

Contributed photo. Desai said the discovery provides potential treatment strategies to head off inflammatory cascades that lie at the heart of many cardiometabolic and neurodegenerative diseases. Macrophages are white blood cells that play critical roles in the immune system and good health.

They swallow up dead or dying cells, allowing the removal of cellular debris, and they patrol for pathogens and other foreign invaders. In this latter role, they act as important sentries for the immune system, calling for help from other immune cells as needed.

Scientists have known that macrophages become less effective with age, but it has been unclear why. These changes, the scientists believe, make the macrophages prone to chronic, low-grade inflammation at the best of times. Some of the genes affected support the function of mitochondria the cell components that produce energy.

As a result of the gene disruption, mitochondria become defective and leak their DNA into cells, sparking inflammation. Scientists used to consider telomere shortening, mitochondrial damage, inflammation, and other processes as separate theories of aging that could contribute to diseases like cancer, DePinho says.

As chronic inflammation sets in, it becomes harder for the immune system to perform routine tasks, like detecting and eliminating cancer cells and pathogens, which could make people more likely to develop diseases.

This burgeoning understanding of inflammaging as a relentless circuit of steps that all exacerbate inflammation is revealing new ways to break the cycle. Efforts to develop anti-aging interventions that target inflammation are challenging because they need to be specific to avoid causing more harm than good, Ferrucci says.

Trying to tackle the chronic inflammation of aging with general anti-inflammatory drugs, for example, could make people more susceptible to disease by impairing the inflammation that our bodies need for staying healthy. It's also quite dangerous. One of the most promising new strategies for dealing with inflammaging is attacking senescent cells, experts say.

In mice, a low-dose combination of two drugs, called Dasatinib and Quercetin, appears to be particularly effective at getting rid of these deadbeat cells and reducing inflammation in the intestines with the potential to extend lives.

Clinical trials are now underway with these and other so-called senolytics to see if the same kinds of compounds might kill senescent cells and break the cycle of inflammation and disease in people too, says DePinho. Other ongoing approaches include efforts to identify drugs that could restore telomeres, enhance mitochondrial function, and activate anti-aging genes, a strategy DePinho is working on.

Although evidence has been seriously questioned and these products have been over-hyped, DePinho says, further study may illuminate new anti-aging properties of sirtuins.

Scientists are hopeful that they are getting closer to understanding which interventions will help most, and studies in mice illustrate the tantalizing possibilities. Advances in immunology are lending new insights into how we can allow good inflammation to proceed while squashing the bad that can come from too much of it, Ferrucci adds.

For now, there are simple steps people can take to address inflammaging in their own bodies, experts say, including exercise. Regular vigorous activity is best, but as little as 15 minutes a day can make a difference, DePinho says, and even leisure activities help.

Dietary choices, too, can improve the chronic inflammatory state of inflammaging, according to a variety of studies that support eating a Mediterranean-style diet with an emphasis on whole grains, produce, nuts, and fish. Eating a wide variety of vegetables may also help sustain the gut microbiome, which tends to become less resilient and contribute to rising levels of inflammation with age.

Each Saturday, when Ferrucci goes to the market to shop for the week, he buys 10 different kinds of vegetables, based on this emerging evidence. Body fat releases cytokines that promote inflammation, DePinho adds, so using exercise and diet to control weight can have extra benefits.

He also advises people to avoid or quit smoking, a habit known to increase DNA damage and drive inflammation. Finding ways to relax is another useful goal, as chronic stress has been linked to shortened telomeres, accelerated aging, and inflammatory diseases. Adequate sleep and meditation can help reduce stress, DePinho says.

Healthy habits like these are important throughout life, Ferrucci says, but they become especially important as the mechanisms that protect our cells from damage become less functional with age.

Inflammation is also a hallmark of cancer and Inflammation and aging aginv recognized to influence all cancer Inflammation and aging from cell transformation to metastasis. Therefore, inflammaging may represent the biological phenomena able to couple ageing process with cancer development. Here we review the molecular and cellular pathway involved in age-related chronic inflammation along with its potential triggers and their connection with cancer development. Ageing is a nearly universal biological process characterized, in multicellular organisms, by the progressive loss of cells functions and tissues renewal due to complex, heterogeneous and dynamic mechanisms and affected by several genetic, epigenetic, environmental and fortuitous factors [ 12 ].

Inflammation and aging -

So what drives this harmful inflammation? The answer is improper calcium signaling in the mitochondria of certain immune cells. Mitochondria are the power generators in all cells, and they rely heavily on calcium signaling.

The UVA Health researchers, led by Bimal N. Desai, PhD, found that the mitochondria in the immune cells called macrophages lose their ability to take up and use calcium with age. This, the researchers show, leads to chronic inflammation responsible for many of the ailments that afflict our later years.

The researchers believe that increasing calcium uptake by the mitochondrial macrophages could prevent the harmful inflammation and its terrible effects.

Macrophages are white blood cells that play critical roles in our immune systems and, in turn, our good health. They swallow up dead or dying cells, allowing our bodies to remove cellular debris, and patrol for pathogens and other foreign invaders. In this latter role, they act as important sentries for our immune systems, calling for help from other immune cells as needed.

Scientists have known that macrophages become less effective with age, but it has been unclear why. These changes, the scientists believe, make the macrophages prone to chronic, low-grade inflammation at the best of times.

Scientists have identified a dozen biological changes that correspond with age. For example, as people get older, their immune cells lose their protective functions and stop doing the job of fighting off invaders, turning into what scientists call senescent cells.

Other kinds of cells can also become senescent in response to stress. They cease replicating, no longer do their jobs, and start to secrete powerful inflammatory molecules that cause yet more cells to become senescent in a self-perpetuating cycle. Meanwhile, DNA damage inside cells accumulates over time, especially at the tips of chromosomes in protective regions called telomeres, which are long stretches of bunched-up DNA.

Each time a cell divides, its telomeres become shorter until they reach a critical length that is perceived by the cell as DNA damage or instability, which may induce cellular senescence.

As telomeres become damaged, they initiate a signaling process through proteins that turn certain genes on and off. Some of the genes affected support the function of mitochondria the cell components that produce energy. As a result of the gene disruption, mitochondria become defective and leak their DNA into cells, sparking inflammation.

Scientists used to consider telomere shortening, mitochondrial damage, inflammation, and other processes as separate theories of aging that could contribute to diseases like cancer, DePinho says. As chronic inflammation sets in, it becomes harder for the immune system to perform routine tasks, like detecting and eliminating cancer cells and pathogens, which could make people more likely to develop diseases.

This burgeoning understanding of inflammaging as a relentless circuit of steps that all exacerbate inflammation is revealing new ways to break the cycle.
