		| ....A look at microbes in the human body..... |  
	
		| ....Microbes may play crucial role in human 
		health, ...researchers discovering
 |  
	
		| Consider this: The average person’s body 
		contains about 100 trillion 
		cells, but only maybe one in 10 is human. 
 This isn’t the latest Hollywood horror flick, or some secret genetic 
		engineering experiment run amok.
 
 This, it turns out, is nature’s way: The human cells that form our skin, 
		eyes, ears, brain and every other part of our bodies are far outnumbered 
		by those from microbes, primarily 
		bacteria but also 
		viruses, 
		fungi and a 
		panoply of other microorganisms.
 
 That thought might make a lot of people lunge for the hand sanitizer, at 
		the least. But that predictable impulse may be exactly the wrong one. A 
		growing body of evidence indicates that the microbial 
		ecosystems that 
		have long populated our guts, mouths, noses and every other nook and 
		cranny play crucial roles in keeping us healthy.
 
 Moreover, researchers are becoming more convinced that modern trends — 
		diet, antibiotics, obsession with cleanliness, Caesarean delivery of 
		babies — are disrupting this delicate balance, contributing to some of 
		the most perplexing ailments, including 
		asthma, 
		allergies, 
		obesity, 
		diabetes, 
		autoimmune diseases, 
		cancer and perhaps even 
		autism.
 
 “In terms of potential for human health, I would place it with stem 
		cells as one of the two most promising areas of research at the moment,” 
		said 
		
		Rob Knight  of the University of Colorado. “We’re seeing an 
		unprecedented rate of discovery. Everywhere we look, microbes seem to be 
		involved.”
 
 Equipped with super-fast new 
		DNA decoders, scientists are accelerating 
		the exploration of this realm at a 
		molecular level, yielding provocative 
		insights into how these microbial stowaways may wield far greater powers 
		than previously appreciated in, paradoxically, making us human.
 
 “The field has exploded,” said Jeffrey 
		I. Gordon of Washington 
		University, who pioneered the exploration of humanity’s microbial 
		inhabitants, known as the “microbiome” or “microbiota.” “People have 
		this sense of wonderment about looking at themselves as a compilation of 
		microbial and human parts.”
 
 Some equate these microbial inhabitants to a newly recognized organ. 
		Acquired beginning at birth, this mass of fellow travelers may help 
		steer normal development, molding immune systems and calibrating 
		fundamental metabolic functions such as energy storage and consumption. 
		There are even tantalizing clues they may help shape brain development, 
		influencing behavior.
 
 “The ‘human supraorganism’ is one term coined to describe the human host 
		and all the attendant microorganisms,” said Lita M. Proctor, who leads 
		the Human Microbiome Project at the National Institutes of Health, which 
		is mapping this world. “There’s been a real revolution in thinking about 
		what that means.”
 
 Investigators are trying to identify which organisms may truly be 
		beneficial “probiotics” that people could take to help their health. 
		Others are finding substances that people might ingest to nurture the 
		good bugs. Drugs may mimic the helpful compounds that these organisms 
		produce.
 
 Doctors have even begun 
		microbiota “transplants”
		to treat a host of 
		illnesses, including a sometimes-devastating gastrointestinal infection 
		called C. difficile, digestive system ailments such as 
		Crohn’s disease, 
		colitis and 
		irritable bowel disorder, and even in a handful of cases 
		obesity and other afflictions, such as 
		multiple sclerosis.
 
 Many advocates of the research urge caution, noting that most of the 
		work so far has involved laboratory animals or small numbers of 
		patients, many hypotheses remain far from proven and nothing has zero 
		risk.
 
 “We have to be very careful in how we state what we know at the present 
		time versus what we think might be true at this point,” said
		David A. Relman of Stanford University. “But it’s probably fair to say that our 
		indigenous communities are more diverse, more complex and more 
		intimately and intricately involved in our biology than we thought.”
 
 Scientists have long known that many organisms evolved with humans and 
		perform vital functions, digesting food, extracting crucial nutrients, 
		fighting off disease-causing entities.
 
 “We feed them and house them and they perform certain metabolic 
		functions for us that we have sort of contracted out,” said
		
		Martin J. Blaser of the New York University School of Medicine. “The homeboys 
		protect their turf from invaders.”
 
 But as microbiologists have begun 
		
		scrutinizing
		
		 these colonies, it has 
		become clearer that they create carefully calibrated enterprises, with 
		unique combinations inhabiting individual crevices and identifiable 
		nuances from person to person.
 
 “We just don’t pick up willy-nilly any microbe in the soil or air we 
		encounter,” Relman said.
 
 European scientists 
		
		reported
		
		 in April that people generally seem to have 
		one of three basic combinations that may be as fundamentally important 
		as, say, blood type.

 The five-year, $175 million U.S. Human Microbiome Project is assembling 
		an outline of a “healthy” microbiome by sampling the mouth, airway, 
		skin, gut and urogenital tract of 300 healthy adults, as well as 
		deciphering the genetic codes of 200 possibly key microbes.
 
 Dozens of studies are also underway, including some that are repeatedly 
		swabbing kids and adults, including twins, to gain insights into why one 
		person gets tooth decay, asthma, ulcerative colitis or even cancer, and 
		another doesn’t.
 
 “We’re using microbes as markers for the onset of various 
		diseases or 
		progression of diseases,” said 
		Karen E. Nelson, who runs the J. Craig 
		Venter Institute in Rockville. “We think we’re going to have a huge 
		impact on health.”
 
 Birth, development and disease
 
 One intriguing 
		finding is that babies born through 
		Caesarean sections 
		apparently miss out on acquiring their mothers’ microbiota.
 
 “The birth canal is very heavily colonized by bacteria,” said 
		
		Maria Dominguez-Bello, a University of Puerto Rico biologist who has been 
		studying microbiota around the world, including in 
		isolated tribes in 
		the Amazon. “We think that is not by chance.”
 
 The rising number of C-section babies denied this colonization, along 
		with the casual use of 
		antibiotics and other factors that can alter the 
		microbiota, might help explain trends such as rising incidents of 
		asthma and 
		food allergies caused by misfiring 
		immune systems. 
		To explore this, 
		researchers have begun following C-section babies, comparing their 
		microbiomes and their health with babies delivered through the birth 
		canal.
 
 The interaction between the microbiota and the immune system may also 
		play a role in other diseases in adults, including those caused at least 
		in part by 
		chronic inflammation from hyperactive immune systems.
 
 “Gut bacteria have figured out a way to network with our immune system 
		so it doesn’t attack them,” said 
		Sarkis K. 
		Mazmanian of the California 
		Institute of Technology.
 
 The microbiota apparently sends signals that dampen the “inflammatory 
		response,” a crucial defense also believed to play a role in a variety 
		of diseases, including many forms of 
		cancer, the “metabolic syndrome” 
		caused by obesity, diabetes and 
		heart disease.
 
 The theory is that one reason some people may be prone to these diseases 
		is that they are missing certain microbes. One anti-inflammatory 
		compound produced by a bacterium appears to cure the equivalent of 
		colitis and multiple sclerosis in mice, both of which are caused by 
		misfiring immune systems, Mazmanian found.
 
 Role in obesity?
 
 Similarly, studies indicate that gut dwellers secrete messengers to 
		cells lining the digestive tract to modulate key 
		hormones, such as leptin and 
		ghrelin, which are players in regulating 
		metabolism, 
		hunger 
		and a sense of fullness.
 
 Pregnant women often take antibiotics, and young children can get 
		several rounds to fight ear and other infections, which can kill off 
		these companions. Farmers commonly add antibiotics to animal feed to 
		fatten their animals faster.
 
 “We may have a generation of children growing up without the proper 
		bacteria to regulate their leptin and ghrelin,” Blaser said.
 
 Obese people appear to have a distinctive mix of digestive bacteria that 
		make them prone to weight gain. Thin mice get fatter when their 
		microbiota is replaced with the microbes of obese animals.
 
 “Our ancient microbiome is losing the equilibrium it used to have with 
		the host — us — and that has profound physiological consequences,” said Blaser, who published his concerns in an August paper in the journal 
		Nature.
 
 Microbes and the mind
 
 Intriguing clues also are emerging about how microbes may affect the 
		brain. Manipulating gut microbiomes of mice influences their 
		anxiety and 
		activity, Swedish researchers reported in January in the 
		
		Proceedings of the National Academy of Sciences.
 
 “This may have implications for new lines of thinking to address some of 
		the 
		psychiatric problems you see among humans,” said
		Sven 
		Pettersson, a 
		professor of host-microbial interaction at the Karolinska Institute. 
		“Together with genetic susceptibility, this may influence what doctors 
		classify as autism or ADHD.”
 
 In another experiment involving mice, a Canadian-Irish team reported in 
		August that bacteria in the gut appear to influence 
		brain chemistry, and 
		corresponding behaviors such as 
		anxiety, 
		stress and 
		depression, via the
		vagus nerve.
 
 “What we’ve shown is you change behavior as well as make changes in the 
		brain,” said John Bienenstock, director of the Brain-Body Institute at 
		McMaster University. “Now we have direct proof how that happens. That’s 
		why this is exciting.”

		MICROBEOME PROJECT... (From 
		
		Wikipedia)
 |  
	
		| The Human Microbiome Project (HMP) is a
		
		United States
		
		National Institutes of Health initiative with the goal of 
		identifying and characterizing the
		
		microorganisms which are found in association with both healthy and
		diseased
		
		humans (their
		
		microbial flora). Launched in 2008,[1] 
		it is a five-year project, best characterized as a feasibility study, 
		and has a total budget of $115 million. The ultimate goal of this and 
		similar
		
		NIH-sponsored microbiome projects is to test if changes in the human 
		microbiome are associated with human health or disease. This topic is 
		currently not well-understood. Important components of the Human Microbiome Project will be 
		culturing-independent methods of microbial
		
		community characterization, such as
		
		metagenomics (which provides a broad genetic perspective on a single 
		microbial community), as well as extensive whole-genome
		
		sequencing (which provides a "deep" genetic perspective on certain 
		aspects of a given microbial community, i.e., of individual bacterial 
		species). The latter will serve as reference
		genomic 
		sequences — 600 such sequences of individual bacterial isolates are 
		currently planned — for comparison purposes during subsequent 
		metagenomic analysis. The
		
		microbiology of five body sites will be emphasized:
		
		oral,
		
		skin,
		
		vaginal,
		gut, 
		and
		
		nasal/lung. 
		The project also financed deep sequencing of bacterial 16S rRNA 
		sequences amplified by PCR from human subjects. |  
	
		| 
		Context and 
		importance of HMPTotal microbial
		
		cells found in association with humans may exceed the total number 
		of cells making up the
		
		human body by a factor of ten-to-one. The total number of genes 
		associated with the human microbiome could exceed the total number of 
		human genes by a factor of
		
		100-to-one. Many of these organisms have not been successfully
		
		cultured, identified, or otherwise characterized. Organisms expected 
		to be found in the human microbiome, however, may generally be 
		categorized as
		
		bacteria (the majority), members of
		
		domain
		Archaea,
		
		yeasts, and
		
		single-celled eukaryotes as well as various
		
		helminth
		
		parasites and
		viruses, 
		the latter including viruses that infect the cellular microbiome 
		organisms (e.g.,
		
		bacteriophages, the viruses of bacteria). 
			"The HMP will address some of the most inspiring, vexing and 
			fundamental scientific questions today. Importantly, it also has the 
			potential to break down the artificial barriers between medical 
			microbiology and environmental microbiology. It is hoped that the 
			HMP will not only identify new ways to determine health and 
			predisposition to diseases but also define the parameters needed to 
			design, implement and monitor strategies for intentionally 
			manipulating the human microbiota, to optimize its performance in 
			the context of an individual's physiology."[1] The HMP has been described as "a logical conceptual and experimental 
		extension of the
		
		Human Genome Project"[2]. 
		In 2007 the 
		Human Microbiome Project was listed on the
		
		NIH Roadmap for Medical Research as one of the New Pathways to 
		Discovery. Organized characterization of the human microbiome is also 
		being done internationally under the auspices of the
		
		International Human Microbiome Consortium. The
		
		Canadian Institutes of Health Research, through the CIHR Institute 
		of Infection and Immunity, is leading the
		
		Canadian Microbiome Initiative to develop a coordinated and focused 
		research effort to analyze and characterize the microbes that colonize 
		the human body and its potential alteration during chronic disease 
		state.  Distributed computing 
		initiative The
		
		distributed computing project
		
		World Community Grid now[when?] 
		operates a human microbiome application, which can be run as background 
		software on home computers with World Community Grid installed. |
