The story of resolving immune dysfunction in Western society is one of uncovering a profound evolutionary mismatch. The story began 39 years ago when a parasitologist, John Turton, intentionally colonized himself with the human hookworm and eliminated his own hayfever . Sadly, the story is littered with long pauses, and Turton’s observations went unappreciated for decades. The story took a new turn in the late 1980s when David Strachan pointed an accusing finger at some aspects of modern sanitation as being responsible for the plague of chronic immune disease affecting Western society .
The Centre for Evolutionary Medicine (ZEM), University of Zurich, is calling for grant applications. The applicants are free to submit any research project within the wider field of Evolutionary Medicine, preferably, but not exclusively, on the study of the evolution of human musculo-skeletal disease. Primary current ZEM research topics (which show the area of research projects covered by this scheme) can be found at www.anatom.uzh.ch/zem.
Roux-en-Y gastric bypass (RYGB) results in rapid weight loss, reduced adiposity, and improved glucose metabolism. These effects are not simply attributable to decreased caloric intake or absorption, but the mechanisms linking rearrangement of the gastrointestinal tract to these metabolic outcomes are largely unknown. Studies in humans and rats have shown that RYGB restructures the gut microbiota, prompting the hypothesis that some of the effects of RYGB are caused by altered host-microbial interactions. To test this hypothesis, we used a mouse model
Genome-wide association studies (GWASs) have identified hundreds of loci harboring genetic variation influencing inflammatory-disease susceptibility in humans. It has been hypothesized that present day inflammatory diseases may have arisen, in part, due to pleiotropic effects of host resistance to pathogens over the course of human history, with significant selective pressures acting to increase host resistance to pathogens.
OBJECTIVE: To determine whether childhood antianaerobic antibiotic exposure is associated with the development of inflammatory bowel disease (IBD).
METHODS: This retrospective cohort study employed data from 464 UK ambulatory practices participating in The Health Improvement Network. All children with ≥2 years of follow-up from 1994 to 2009 were followed between practice enrollment and IBD development, practice deregistration, 19 years of age, or deat
; those with previous IBD were excluded. All antibiotic prescriptions were captured. Antianaerobic antibiotic agents were defined as penicillin, amoxicillin, ampicillin, penicillin/β-lactamase inhibitor combinations, tetracyclines, clindamycin,
Cancer development is widely recognized to be a somatic cell evolutionary process with complex dynamics and highly variable time frames. Variant cells and descendent subclones gain competitive advantage via their fitness in relation to micro-environmental selective pressures. In this context, the ‘unit’ of selection is the cell, but not any cell. The so-called ‘cancer stem cells’ have the essential properties required to function as the key units of selection, particularly with respect to their proliferative potential and longevity. These cells drive evolutionary progression of disease and provide reservoirs for relapse or recurrence and drug resistance. They represent the prime, but elusive and moving, targets for therapeutic control.
Author Summary Human tuberculosis (TB) caused by Mycobacterium tuberculosis kills 1.5 million people each year. M. tuberculosis has been affecting humans for millennia, suggesting that different strain lineages may be adapted to specific human populations. The combination of a particular strain lineage and its corresponding patient population can be classified as
