Molecular 'switch' reverses chronic inflammation and aging:
Chronic inflammation, which results when old age, stress or environmental toxins keep the body's immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer's and Parkinson's to diabetes and cancer.
Now, scientists at the University of California, Berkeley, have identified a molecular "switch" that controls the immune machinery responsible for chronic inflammation in the body. The finding, which appears online Feb. 6 in the journal Cell Metabolism, could lead to new ways to halt or even reverse many of these age-related conditions.
[...] In the study, Chen and her team show that a bulky collection of immune proteins called the NLRP3 inflammasome -- responsible for sensing potential threats to the body and launching an inflammation response -- can be essentially switched off by removing a small bit of molecular matter in a process called deacetylation.
Overactivation of the NLRP3 inflammasome has been linked to a variety of chronic conditions, including multiple sclerosis, cancer, diabetes and dementia. Chen's results suggest that drugs targeted toward deacetylating, or switching off, this NLRP3 inflammasome might help prevent or treat these conditions and possibly age-related degeneration in general.
"This acetylation can serve as a switch," Chen said. "So, when it is acetylated, this inflammasome is on. When it is deacetylated, the inflammasome is off."
[...] "I think this finding has very important implications in treating major human chronic diseases," Chen said. "It's also a timely question to ask, because in the past year, many promising Alzheimer's disease trials ended in failure. One possible explanation is that treatment starts too late, and it has gone to the point of no return. So, I think it's more urgent than ever to understand the reversibility of aging-related conditions and use that knowledge to aid a drug development for aging-related diseases."

It is worse than that, the low fat, high sugar diet they recommend interferes with vitamin c absorption and transport (dehydroascorbate competes with glucose for glut1/3 transporters).
So they are feeding you stuff to make you deficient in vitamin c then trying to come up with dozens of different expensive and dangerous treatments to fix the myriad of problems caused by the diet.

It's obvious they don't want to "cure" disease, only find patches for "symptoms".
It is well understood "inflammation" is a symptom of something else. In reality, inflammation is natural reaction to _something else entirely_. Like maybe deteriorating DNA, or toxins like heavy metals or preservative type chemicals built up in the body over decades. Where a weak immune system is failing.
But you can't sell prevention, because if no one is sick they don't need your medicine. So, find something, anything and cure that, even if it's not the disease but sure looks bad.

Well, when doctors don't have a cure, or it might take too long, they do their best with what they have at their disposal and treat symptoms. If nothing else, treating symptoms often / usually gives patients relief & better quality of life.
Doctors are pretty boxed in by FDA, lawyers/courts, patient expectations & demands, etc. And many diseases / conditions will "resolve" with treatment, you know, the body healing itself.
Which brings me to inflation: as you wrote, inflation is a very frequent body's response to something being wrong. However, inflation in and of itself usually causes damage and many more problems, so reducing inflation often results in faster healing.
However, inflation is often treated with steroids, and steroids usually suppress the immune system, so doctors are often forced to make difficult and compromising decisions.

You mean inflammation. The mechanism via which inflammation can damage your tissue is via oxidation.
