GUT BACTERIA INFLUENCE AUTISM-LIKE BEHAVIORS IN MICE

Using germ-free mouse models, researchers transplanted fecal bacteria from children on the autism spectrum and neurotypical children. Mice who received the transplants from the ASD cohort began to exhibit autism-like behaviors, whereas the mice who received transplants from typically developing children did not. Additionally, the mice showed altered gene expression in their brains and differences in types of metabolites present. In particular, the ASD mice had lower levels of 5AV and taurine. Findings suggest gut microbiota regulates autism-like behaviors via the production of neuroactive metabolites, providing further evidence for the gut-brain axis connection to the pathology of autism. READ MORE…

HOW STRESSED-OUT GUT BACTERIA MAY TRIGGER AUTOIMMUNE RESPONSE

Chronic social stress in mice induces the expression of virulent genes in the gut microbiota. The altered microbiota increases the presence of effector T helper cells in the lymph nodes and induces myelin autoreactive cells. Exposure to chronic stress, therefore, may increase the risk of developing autoimmune diseases for some individuals with a susceptibility. READ MORE…

COAT OF PROTEINS MAKES VIRUSES MORE INFECTIOUS AND LINKS THEM TO ALZHEIMER’S DISEASE

Herpes simplex virus type 1 (HSV-1) and respiratory syncytial virus (RSV) interact with biological fluids, creating a coat of proteins around the viral surface. This results in the viruses becoming more infectious and can contribute to the formation of amyloid plaques. In animal models, researchers found these viruses can bind to amyloid proteins, which aggregate into plaques that contribute to Alzheimer’s disease. HSV-1 is able to accelerate the transformation of soluble amyloid proteins into amyloid plaques. READ MORE…

The gut–hormone connection: how gut organisms impact estrogen levels

Emerging research demonstrates that the gut microbiome assumes a central job in the regulation of estrogen levels inside the body and in this manner impacts the danger of creating estrogen-related sicknesses, for example, endometriosis, polycystic ovary disorder, bosom disease, and prostate cancer.

Scientific research has shown that gut microorganisms manage numerous parts of human physiology, including intestinal penetrability, the ingestion of supplements from sustenance, and resistance. In any case, recent studies recommend that gut organisms assume another crucial job in the human body by regulating circulating estrogen levels.

The estrobolome is the collection of microbes equipped for using estrogens. The estrobolome adjusts the enterohepatic course of estrogens and influences flowing and discharged estrogen levels. Microorganisms in the estrobolome produce beta-glucuronidase, a protein that deconjugates estrogens into their dynamic structures. Beta-glucuronidase movement produces dynamic, unbound estrogen that is fit for official to estrogen receptors and impacting estrogen-dependent physiological procedures.

At the point when the gut microbiome is healthy, the estrobolome delivers only the appropriate measure of beta-glucuronidase to keep up estrogen homeostasis. In any case, when gut dysbiosis is available, beta-glucuronidase action might be changed. This produces either a lack or an abundance of free estrogen, subsequently advancing the improvement of estrogen-related pathologies.

Gut Dysbiosis Is Connected to Estrogen-Related Diseases

Estrogen assumes numerous crucial roles in the human body. It controls fat deposition and adipocyte differentation, female reproductive function, cardiovascular health, bone turnover, and cell replication. Gut dysbiosis can possibly modify the estrobolome, upset estrogen homeostasis, and weaken these procedures, promoting the improvement of chronic diseases.

Weight, Cardiovascular Disease, and Osteoporosis

In postmenopausal women, estrobolome interruption is related with an expanded risk of obesity, cardiovascular disease, and osteoporosis. Estrogens control glucose and lipid metabolism, adipocyte differentation, bone development, and the inflammatory reaction in atherosclerosis. Research shows that the typical decreases in estrogen that happen at menopause hinder these estrogen-dependent procedures, triggering obesity, cardiovascular disease, and osteoporosis.

Gut dysbiosis resulting decreased beta-glucuronidase movement may exarcerbate the low-estrogen state in postmenopausal ladies, further expanding the risk of these chronic diseases.

Endometriosis

Endometriosis, an estrogen-driven condition described by the development of endometrial tissue outside the uterus, has been related with gut dysbiosis. The estrobolome of women with endometriosis may have bigger numbers of beta-glucuronidase-producing bactera, prompting increased levels of circling estrogen, which drives endometriosis.

PCOS

Polycystic ovary syndrome (PCOS) may also be affected by estrobolome disruption. Ladies with PCOS have an excess of androgens in connection to estrogen, just as an adjusted gut microbiota. Analysts estimate that the changed gut microbiota in PCOS women may promote increased androgen biosynthesis and dicreased estrogen levels through lowered beta-glucuronidase activity.

Probiotics Can Restore a Healthy Estrogen Balance

Research demonstrates that it might be possible to modulate the estrobolome and turn around estrogen-related pathologies through probiotic supplementation.

 

  • Supplementation with an broad range Lactobacillus probiotic has been found to standardize the estrous cycle and decrease testosterone biosynthesis in a animal model of PCOS.
  • In an animal model of endometriosis, Lactobacillus gasseri prevented ectopic tissue development, which is an estrogen-driven procedure.
  • In a menopausal mouse model of osteoporosis, Lactobacillus reuteri anticipated bone misfortune coming about because of low estrogen.
  • Lactobacilli have anticarcinogenic effects in breast tissue, proposing that supplementation might be helpful for the prevention of breast cancer.

While research on the connection between probiotic supplementation and the estrobolome is still in its earliest stages, this shouldn’t prevent professionals from prescribing probiotics to their patients with estrogen-related conditions. Switching dysbiosis gives off an impression of being key for adjusting the estrobolome, and probiotic supplementation is a generally simple and cheap approach to achieve this.

Helminth immunomodulation in autoimmune disease

Helminths have advanced to progress toward becoming specialists at subverting immune surveillance. Through potent and persistent immune tempering, helminths can stay undetected in human tissues for a long length of time.

Diverting the immunomodulating “abilities” of helminths to treat inflammatory human diseases is getting intensive intrigue. Here, we survey treatments using live parasitic worms, worm emissions, and worm-derived synthetic atoms to treat immune system illness.

We survey helminth treatment in both mouse models and clinical trials and talk about what is known on systems of activity. We additionally feature momentum advance in portraying promising new immunomodulatory particles found in excretory/secretory results of helminths and their potential use as immunotherapies for acute and chronic inflammatory diseases.

With the collecting worldwide weight of autoimmune disease, helminths have happened to elevated scientific interest because of their ability to activate immunoregulatory circuits and control immunity. There is solid proof in mouse models that helminthic treatment, ES components, and helminth-derived synthetic atoms can treat as well as prevent inflammatory disease, for example, IBD, T1D, MS, RA, and asthma. Up to this point, human trials in celiac disease, UC, Cd, MS, RA, and psoriasis have set up that treatment is safe with some proof of therapeutic effect. Be that as it may, brings the first wave of human trials are not as striking as mouse disease models.

Common parasite uncovers key cause of Crohn’s disease

Immune systems have their sinister side, especially when they have not learned how hard to fight. Crohn’s disease and other inflammatory bowel diseases inflict more than a million Americans with debilitating pain and digestive unrest because of uncontrolled immune responses in the gut.

How this happens remained a mystery until immunologists at Cornell’s College of Veterinary Medicine caught a key culprit in Crohn’s disease: a cell from our own immune forces. With unconventional help from a common parasite, Eric Denkers, professor of immunology, and research associate Charlotte Egan identified a renegade cell responsible for this largely arcane and increasingly prevalent illness.

“Auto-immune diseases are on the rise in this country but their causes have remained largely unknown,” said Denkers. “It’s possible that these diseases are more common in the West because we’re too clean. Exposure to germs trains immune systems how to respond to threats. Early protection from germs may contribute to the increasing prevalence of immune system overreactions in our population, leading to auto-immune problems like allergies and inflammatory bowel disease.”

Similar symptoms arise when some hosts first face the prevalent protozoan Toxoplasma gondii. Denkers’ lab studies this parasite’s arsenal of host-manipulating powers, but recently they have steered Toxoplasma research in an entirely new direction.

“We noticed that the initial intestinal inflammation these parasites can cause looks very similar to what happens during Crohn’s disease,” said Denkers, one of the first to study this connection. “Our lab has started using Toxoplasma to model Crohn’s disease in humans and help us find the pivotal perpetrator, which has turned out to be a cell from our own immune forces.”

Specialized immune cells called intraepithelial lymphocytes patrol intestinal walls. Upon encountering invaders, they release messenger proteins that call more immune cells to the battleground. “Too many messenger proteins recruit too many immune cells, causing inflammation that can devastate the host’s own tissue,” Denkers explained. “Bad balance between good bacteria, bad bacteria, and immune interactions like inflammation cause Crohn’s disease.”

“For the first time we’ve discovered how infection can turn these immune cells pathogenic, stimulating them to cause disease, inflammation and necrosis in the small intestine,” said Denkers. “This marks a major leap toward understanding human Crohn’s disease. Unveiling this kind of immunological interplay may lead to improved prevention and care in an array of auto-immune diseases.”

Denkers and colleagues published their discovery in Mucosal Immunology, followed by a review article discussing Toxoplasma infection as a model for Crohn’s disease in the Journal of Biomedicine and Biotechnology in 2010.
