The Toxins of William B. Coley

Training The Immune System To Fight Cancer Has 19th-Century Roots
December 28, 2015
http://www.npr.org/sections/health-shots/2015/12/28/459218765/cutting-edge-cancer-treatment-has-its-roots-in-19th-century-medicine

A novel immunotherapy drug is credited for successfully treating former President Jimmy Carter’s advanced melanoma. Instead of killing cancer cells, these drugs boost the patient’s immune system, which does the job instead.

Immunotherapy is cutting-edge cancer treatment, but the idea dates back more than 100 years, to a young surgeon who was willing to think outside the box.

Parasites as the treatment

Helminth infection promotes colonization resistance via type 2 immunity

Parasitic worms affect gut microbes
Improved hygiene practices in high-income countries may come with an increased risk of developing inflammatory bowel disease (IBD) or other similar disorders. Ramanan et al. show that intestinal helminth infection, caused by parasitic worms, protects IBD-susceptible mice from developing the disease.
The infection increases specific protective species and limits other inflammatory members of the microbiota.
People from helminth-endemic regions harbored a similar protective microbiota, and their deworming led to an increase in inflammatory Bacteroidales species, similar to what the authors observed in the mice. Thus, a changing microbial environment may shape susceptibility to inflammatory disease.

Measles-associated immune memory loss

Long-term measles-induced immunomodulation increases overall childhood infectious disease mortality
Science 8 May 2015: Vol. 348  no. 6235  pp. 694-699
Michael J. Mina, et al.

Immunosuppression after measles is known to predispose people to opportunistic infections for a period of several weeks to months. Using population-level data, we show that measles has a more prolonged effect on host resistance, extending over 2 to 3 years. We find that nonmeasles infectious disease mortality in high-income countries is tightly coupled to measles incidence at this lag, in both the pre- and post-vaccine eras. We conclude that long-term immunologic sequelae of measles drive interannual fluctuations in nonmeasles deaths. This is consistent with recent experimental work that attributes the immunosuppressive effects of measles to depletion of B and T lymphocytes. Our data provide an explanation for the long-term benefits of measles vaccination in preventing all-cause infectious disease. By preventing measles-associated immune memory loss, vaccination protects polymicrobial herd immunity.

Celiac disease & new varieties of wheat

Doctors Say Changes In Wheat Do Not Explain Rise Of Celiac Disease
September 26, 2013
http://www.npr.org/blogs/thesalt/2013/09/26/226510988/doctors-say-changes-in-wheat-do-not-explain-rise-of-celiac-disease

“We know that celiac disease has doubled in the last 20 years,” Davis says.
And he says we known that humans have probably not changed, “so the more likely culprit is the wheat itself.”

It’s true that about 40 years ago, breeders introduced new varieties of wheat that helped farmers increase their grain yields. Those varieties, which came out of the Green Revolution, now make up 90 percent of all the wheat that farmers grow around the world.

But the claim that the more productive wheat is somehow making people sick didn’t sound right to scientists who work with the crop.
“I never thought that wheat was toxic,” says Donald Kasarda, who has studied gluten proteins for more than 40 years as a research chemist for the U.S. Department of Agriculture.
Leffler says it’s true that the prevalence of celiac disease is up. About 1 percent of the population has this condition, which makes it very vulnerable to even small amounts of gluten, and they say it isn’t just due to better diagnosis and awareness.

There’s also a growing consensus that another portion of the population does have a nonceliac gluten sensitivity.
That means they test negative for celiac disease but have some similar symptoms — like diarrhea, abdominal pain and headaches — after eating foods with gluten.

Leffler says there’s likely no single cause leading to the increased prevalence of celiac. And he doesn’t agree with the notion that changes to modern wheat could explain what’s happening.
“We sort of chafe at these oversimplistic theories that purport to explain an entire rise in a disease,” he says.

Leffler says the increase in celiac disease comes at a time when lots of other autoimmune diseases and allergies are on the rise, too.
And one theory that might help explain this phenomenon is the so-called hygiene hypothesis.

Gluten free: new labeling standard

Truth In Labeling: Celiac Community Cheers FDA Rule For Gluten Free
August 06, 2014
http://www.npr.org/blogs/thesalt/2014/08/06/338306544/truth-in-gluten-free-labeling-celiac-community-cheers-fda-rule

As of Aug. 5, all food manufacturers must be in compliance with a new labeling standard set by the Food and Drug Administration.

The rule states that foods may be labeled “gluten free” only if there’s less than 20 parts per million of the protein.

GWAS explains only a small proportion of the total heritability

By exploiting allied phenotypic data, it is possible to examine the genetic contribution to such aspects of disease biology (including prognosis) by comparing the genetic profiles of patients with contrasting clinical phenotypes—a so-called ‘within-cases’ analysis.

Prognosis in autoimmune and infectious disease: new insights from genetics
Clinical & Translational Immunology (2014) 3, e15
http://www.nature.com/cti/journal/v3/n5/full/cti20148a.html
James C Lee, et al.

Keywords: autoimmunity; FOXO3; genetics; infection; prognosis

despite the apparent success, GWAS results have only explained a relatively small proportion of the total heritability of each disease.[3]
Work is now underway to try to identify the ‘missing heritability’ through a variety of complementary methods, including:

  • whole-genome sequencing (to identify rare variants that may have larger effect sizes) and
  • studies to examine interactions between a given gene and other genes (epistasis) and
  • between genes and the environment.

The Invisible Universe Of The Human Microbiome

The Invisible Universe Of The Human Microbiome
NPR. Nov 5, 2013
http://www.youtube.com/watch?v=5DTrENdWvvM

The next time you look in a mirror, think about this: In many ways you’re more microbe than human.
There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells.
But these tiny compatriots are invisible to the naked eye.
So we asked artist Ben Arthur to give us a guided tour of the rich universe of the human microbiome.

Cross-talk between neural stem cells and immune cells: the key to better brain repair?

Cross-talk between neural stem cells and immune cells: the key to better brain repair?

Systemic or intracerebral delivery of neural stem and progenitor cells (NSPCs) and activation of endogenous NSPCs hold much promise as potential treatments for diseases in the human CNS. Recent studies have shed new light on the interaction between the NSPCs and cells belonging to the innate and adaptive arms of the immune system. According to these studies, the immune cells can be both beneficial and detrimental for cell genesis from grafted and endogenous NSPCs in the CNS, and the NSPCs exert their beneficial effects not only by cell replacement but also by immunomodulation and trophic support. The cross-talk between immune cells and NSPCs and their progeny seems to determine both the efficacy of endogenous regenerative responses and the mechanism of action as well as the fate and functional integration of grafted NSPCs. Better understanding of the dialog between NSPCs and innate and adaptive immune cells is crucial for further development of effective strategies for CNS repair.
