A recent study from the University of Oxford that analyzed 17.4 million UK adults showed Age is the most substantial risk factor Associated with death.
Other risk factors include being male, uncontrolled diabetes and severe asthma.
Given the gerolavic nature - harmful to the old - of the virus, some gerontologists claim that Treating “aging” can be a long term solution To defend older adults from and other future infectious diseases. Although more study needs to be done, A recent study Listed NAD + boosting agents such as NMN and NR As one of the potential treatments. Other scientists also Hypothesized That older adults might benefit from NAD + 's longevity effects and prevent the deadly over-activation of immune responses called a cytokine storm, in which the body attacks its cells rather than the virus. The Cell uses up NAD + during the fight Against coronavirus, weakening our body, according to a recent study that has not been peer-reviewed.
NAD + is essential for innate immune defense against viruses.
The researchers of the study are trying to assess whether NAD + boosters can help humans beat the pandemic. While scientists are in the lab racing time to find a cure for,physicians on the front lines running out of options turn to innovative techniques. As a last resort to treat his mapping,doctor Robert Huizenga of Cedars Sinai Medical Center Administered an NMN cocktail infused with boosters like zinc To the patient to calm the cytokine storm stirred up by.
The NMN cocktail brought down the patients 'fever and inflammation levels within 12 hours.
During the pandemic, NMN is receiving more and more attention for its role in maintaining the immune system balance, which may be a possible treatment for the coronavirus. With the preliminary studies showing some positive results, although not a guaranteed cure, many scientists and physicians believe the NAD + booster 's effect on. Aging
NAD + is the fuel that helps Sirtuins sustain genome integrity and promote DNA repair .
Like a car cannot drive without fuel, sirtuins 'activation requires NAD +。
Results from animal studies showed that raising NAD + level in the body activates sirtuins and increases the lifespans of yeast, worms and mice. Although animal studies showed promising results in anti-aging properties, scientists are still studying how these results can translate to humans. Metabolic Disorders NAD + is one of the keys to Maintaining healthy mitochondrial functions And steady energy output. Aging and high-fat diet reduces the level of NAD + in the body. Studies have shown that taking NAD + boosters can alleviate diet-associated and age-associated weight gain in mice and improve their exercise capacity, even in aged mice.
Other studies even reversed the diabetes effect in female mice, showing new strategies to fight metabolic disorders, such as obesity.
Heart Function Boosting NAD + levels protects the heart And improves cardiac functions. High blood pressure can cause an enlarged heart and blocked arteries that lead to strokes. In mice, NAD + boosters have replenished NAD + levels in the heart and prevented injuries to the heart caused by a lack of blood flow. Other studies have shown that NAD + boosters can protect mice from abnormal heart enlargement.
Neurodegeneration In mice with Alzheimer 's, raising the NAD + level can decrease protein build up that disrupts cell communication in the brain to Increase cognitive function . Boosting NAD + levels also protects brain cells from dying when there 's insufficient blood flow to the brain. Many studies in animal models present new prospects of helping the brain age healthily, defending against Neurodegeneration And Improving memory .
“Natural compound reduces signs of aging in healthy mice.”
As adults get older the immune system declines, people get ill more easily, and it becomes harder for people to Bounce back from illnesses such as the seasonal flu, or even .
Recent studies have suggested that NAD + levels play an important role in regulating inflammation and cell survival during the immune response and aging.
The study underscored the therapeutic potential of NAD + for immune dysfunction. How Does the Body Make Nicotinamide Adenine Dinucleotide (NAD +)? Our bodies naturally produce NAD + from sulfur components, or precursors. Think of them as the raw materials for NAD +。
There are five main precursors that occur in the body: tryptophan, nicotinamide (Nam), nicotinic acid (NA, or niacin), nicotinamide riboside (NR), and nicotinamide. Of these, NMN represents one of the final steps of NAD + synthesis.
These precursors can all come from diet.
Nam, NA and NR are all forms of vitamin B3, an important nutrient. Once in the body, our cells can synthesize NAD + by several different pathways. A biochemical pathway is equivalent to a factory production line.
In the case of NAD +, multiple production lines all lead to the same product.
The first of these pathways is called the de novo pathway. De novo is a Latin expression that equates to “from scratch.”
The de novo pathway begins with the earliest of the NAD + precursors, tryptophan, and builds upwards from there. The second pathway is called the salvage pathway. Harden, along with Hans von Euler-Chelpin, continued to peel apart the mysteries of fermentation. They were awarded the Nobel Prize in 1929 for developing a detailed understanding of these processes, including the chemical shape and properties of what would soon be known as NAD.
The story of NAD expanded in the 1930 's, under the guidance of Otto Warburg, another Nobel laureate, who discovered NAD' s central role in facilitating many. Warburg discovered that NAD serves as a sort of biological relay for electrons. The transfer of electrons from one molecule to another, serves as the basis for the energy needed to perform all biochemical reactions.
In 1937, Conrad Elvehjem and colleagues at the University of Wisconsin, Madison, Discovered that NAD + supplementation cured dogs of pellagra ,Or “Black Tongue.” In humans, pellagra causes a host of symptoms, including diarrhea, dementia, and sores in the mouth. It stems from a niacin deficiency and is now regularly treated with nicotinamide, one of the precursors to NMN.
Arthur Kornberg 's research on NAD + throughout the 40' s and 50 'was instrumental in leading him to discover the principles behind DNA replication and RNA transcription, two processes vital for life. In 1958, Jack Preiss and Philip Handler uncovered the Three biochemical steps By which nicotinic acid is converted to NAD. This series of steps, called a pathway, is known today as the Preiss-Handler Pathway.
In 1963, Chambon, Weill, and Mandel reported that nicotinamide mononucleotide (NMN) provided the energy needed to activate an important nuclear enzyme . This discovery paved the way for a series of remarkable discoveries on a type of protein called a PARP.
PARPs play crucial roles in repairing DNA damage, regulating cell death, and whose activity is associated with changes in lifespan.
In 1976, Rechsteiner and his colleagues found convincing evidence NAD + seemed likely to have “some other major function” in mammalian cells, beyond its classical biochemical role. This discovery made it possible for Leonard Guarente and his colleagues to discover that proteins called sirtuins use NAD to extend life span by differentially keeping some genes “silent.” Since then, interest has grown in NAD and its intermediates, NMN and NR, for their potential to ameliorate a number of age-related health issues. The Future of Nicotinamide Mononucleotide
With the promising therapeutic properties that NMN showed in animal studies, researchers are aiming to understand how this molecule works in the human body.
A recent clinical trial in Japan demonstrated that the molecule is safe and well tolerated at the used dosage. More studies and human trials are on the way. It is a fascinating and versatile molecule, from which we still have much to learn. Journal Reference
