Microbiome and Brain

  • Advances in Human Microbiome Science: Gut–Brain Interaction

    Organizers: John Hambor (Boehringer Ingelheim), Sarkis Mazmanian (California Institute of Technology), Nilufer Seth (Pfizer), Erick Young (Boehringer Ingelheim), Sonya Dougal (The New York Academy of Sciences), and Caitlin McOmish (The New York Academy of Sciences)Presented by the Microbiome Science Discussion Group
    Reported by Hannah Rice | Posted May 26, 2016

    Overview

    On March 15, 2016, the Academy's Microbiome Science Discussion Group convened researchers for Advances in Human Microbiome Science: Gut–Brain Interaction, the second of three symposia on the causal relationships between microbiota and disease—this one focused on the microbiome–gut–brain axis. Commensal human colon microbiota are integral to numerous functions that maintain health. While research on these organisms has traditionally focused on disorders of the gut, there is growing interest in their connection to the central nervous system (CNS). The interconnectedness of the gut and the brain—the association between dysregulation of the gut microbiome and psychiatric disorders, neurodegeneration, and impaired brain development, for example—raises the possibility of targeting the microbiome to treat neurological diseases. The meeting featured presentations by scientists studying the gastrointestinal system and the brain and a panel discussion on translating discoveries into therapeutics.
    "Friends with brain benefits" was the description John Cryan of University College Cork gave gut microbiota in his talk on microbial regulation of neural function. He discussed the intriguing links between stress, microbiota, brain health, and aging. Maternal separation is a well-defined mouse model of anxiety and depression; it also exhibits gastrointestinal symptoms of gut inflammation, elevated proinflammatory cytokines, gut-barrier permeability, and increased colonic transit. Indeed, the model is used to study both depression and irritable bowel syndrome (IBS). In another animal model of anxiety, prenatal stress produces heightened stress responses and a low-diversity microbiome in adult mice. In humans, maternal stress alters the infant microbiome, which may also be affected by Cesarean section, formula feeding, maternal infection, and antibiotic use. In older adults, stress is associated with proinflammatory immune responses, a hallmark of aging, and changes in gut-barrier function, along with cognitive impairment, anxiety, depression, and social isolation. Health in older adults correlates with a diverse gut microbiome, which is strongly associated with diet./.../

INTERSTROKE

We completed a standardised international case-control study in 32 countries in Asia, America, Europe, Australia, the Middle East, and Africa. Cases were patients with acute first stroke (within 5 days of symptom onset and 72 h of hospital admission). Controls were hospital-based or community-based individuals with no history of stroke, and were matched with cases, recruited in a 1:1 ratio, for age and sex. All participants completed a clinical assessment and were requested to provide blood and urine samples. Odds ratios (OR) and their population attributable risks (PARs) were calculated, with 99% confidence intervals.

Findings

Between Jan 11, 2007, and Aug 8, 2015, 26 919 participants were recruited from 32 countries (13 447 cases [10 388 with ischaemic stroke and 3059 intracerebral haemorrhage] and 13 472 controls). Previous history of hypertension or blood pressure of 140/90 mm Hg or higher (OR 2·98, 99% CI 2·72–3·28; PAR 47·9%, 99% CI 45·1–50·6), regular physical activity (0·60, 0·52–0·70; 35·8%, 27·7–44·7), apolipoprotein (Apo)B/ApoA1 ratio (1·84, 1·65–2·06 for highest vs lowest tertile; 26·8%, 22·2–31·9 for top two tertiles vs lowest tertile), diet (0·60, 0·53–0·67 for highest vs lowest tertile of modified Alternative Healthy Eating Index [mAHEI]; 23·2%, 18·2–28·9 for lowest two tertiles vs highest tertile of mAHEI), waist-to-hip ratio (1·44, 1·27–1·64 for highest vs lowest tertile; 18·6%, 13·3–25·3 for top two tertiles vs lowest), psychosocial factors (2·20, 1·78–2·72; 17·4%, 13·1–22·6), current smoking (1·67, 1·49–1·87; 12·4%, 10·2–14·9), cardiac causes (3·17, 2·68–3·75; 9·1%, 8·0–10·2), alcohol consumption (2·09, 1·64–2·67 for high or heavy episodic intake vs never or former drinker; 5·8%, 3·4–9·7 for current alcohol drinker vs never or former drinker), and diabetes mellitus (1·16, 1·05–1·30; 3·9%, 1·9–7·6) were associated with all stroke. Collectively, these risk factors accounted for 90·7% of the PAR for all stroke worldwide (91·5% for ischaemic stroke, 87·1% for intracerebral haemorrhage), and were consistent across regions (ranging from 82·7% in Africa to 97·4% in southeast Asia), sex (90·6% in men and in women), and age groups (92·2% in patients aged ≤55 years, 90·0% in patients aged >55 years). We observed regional variations in the importance of individual risk factors, which were related to variations in the magnitude of ORs (rather than direction, which we observed for diet) and differences in prevalence of risk factors among regions. Hypertension was more associated with intracerebral haemorrhage than with ischaemic stroke, whereas current smoking, diabetes, apolipoproteins, and cardiac causes were more associated with ischaemic stroke (p<0 p="">

Interpretation

Ten potentially modifiable risk factors are collectively associated with about 90% of the PAR of stroke in each major region of the world, among ethnic groups, in men and women, and in all ages. However, we found important regional variations in the relative importance of most individual risk factors for stroke, which could contribute to worldwide variations in frequency and case-mix of stroke. Our findings support developing both global and region-specific programmes to prevent stroke./...,/

Brain words representation

How Words Are Represented in the Brain

Source: University of Pittsburgh.
Image shows a brain with the fusiform gyrus highlighted.
Using direct neural recordings from the visual word form area, researchers were able to see words that patients read as the patients read them.
Reading is a relatively modern and uniquely human skill. For this reason, visual word recognition has been a puzzle for neuroscientists because the neural systems responsible for reading could not have evolved for this purpose. “The existence of brain regions dedicated to reading has been fiercely debated for almost 200 years,” said Avniel Ghuman, an assistant professor in the University of Pittsburgh Department of Neurological Surgery. “Wernicke, Dejerine, and Charcot, among the most important and influential neurologists and neuroscientists of the 19th century, debated whether or not there was a visual center for words in the brain.”/.../

Scientists have discovered never-before-seen vessels in the brain
"They'll have to rewrite the textbooks."
FIONA MACDONALD
19 JUL 2016
Scientists in the US have discovered a new series of lymphatic vessels in the body that link the brain to the immune system - a connection researchers had previously thought didn't exist.
The discovery could not only prompt a rewrite of the textbooks, it might also lead to a new understanding of how our immune system influences our brain and our behaviour.

Experimental anticancer drug may tackle heart disease, too

A new antibody drug may reverse the dangerous buildup of fatty plaque (shown in gray in the cross-section above) on artery walls (orange).Experimental anticancer drug may tackle heart disease, too

What do a cancerous tumor and fatty buildup in an artery have in common? Their harmful cells may have the same way of hiding themselves from the immune system, a study out today suggests. In the new work, researchers studying atherosclerosis—the progressive buildup of fat-laden cells into arterial plaque—found a signaling molecule that may prevent dead cells in the arteries from being eaten and disposed of. Blocking that signal, they found, reduces arterial plaque in mice. And because their signal blocker is an antibody already in phase I clinical trials for cancer treatment, they’re hoping to make a quick jump into human testing for cardiovascular disease.
“It’s going to be a new platform of therapy, not just another cholesterol-lowering drug,” says Nicholas Leeper, a vascular biologist at Stanford University in Palo Alto, California, and senior author on the new study.
Although cholesterol contributes to atherosclerosis, the story of the disease’s progression is much more complex. When these fatty deposits damage an artery wall, immune cells flock to the scene—notably macrophages, which gobble up dying and damaged cells all over the body. But when they arrive at the inflamed artery, they fail to perform that cleanup. Soon, dying muscle cells and dying macrophages join a growing plaque on the artery wall. Nestled inside is a “necrotic core,” a graveyard of cells that destabilizes the rest of the plaque and makes it prone to rupture, which can block the artery and cause a heart attack or stroke./.../

Whenever I see my 10-year-old daughter brimming over with so much energy that she jumps up in the middle of supper to run around the table, I think to myself, "those young mitochondria."
Mitochondria are our cells' energy dynamos. Descended from bacteria that colonized other cells about 2 billion years, they get flaky as we age. A prominent theory of aging holds that decaying of mitochondria is a key driver of aging. While it's not clear why our mitochondria fade as we age, evidence suggests that it leads to everything from heart failure to neurodegeneration, as well as the complete absence of zipping around the supper table./.../

Na área da reumatologia sua contribuição também foi notável. Trabalhou no grupo de John Vane no Royal College of Surgeons, no estudo da atividade anti-inflamatória da aspirina, demonstrando que a ação era devida à capacidade de inibir a produção de prostaglandinas, numa provável competição com o sítio ativo da enzima cicloxigenase (COX).

Infantile Memory Study Points to Critical Periods in Early-Life Learning for Brain Development

Summary: A new study on infantile memory formation in rats points to the importance of critical periods in early-life learning on functional development of the brain.
Source: NYU.
A new study on infantile memory formation in rats points to the importance of critical periods in early-life learning on functional development of the brain. The research, conducted by scientists at New York University’s Center for Neural Science, reveals the significance of learning experiences over the first two to four years of human life; this is when memories are believed to be quickly forgotten—a phenomenon known as infantile amnesia.
“What our findings tell us is that children’s brains need to get enough and healthy activation even before they enter pre-school,” explains Cristina Alberini, a professor in NYU’s Center for Neural Science, who led the study. “Without this, the neurological system runs the risk of not properly developing learning and memory functions.”
