Is to use the concept of molecular mimicry to physiologically bind well-described pharmacological targets with bacterial metabolites and derived small molecules
TargEDys® translates its unique understanding of the gut-brain axis to develop and manufacture nutritional and therapeutic solutions to control metabolic diseases. The company aims to be at the forefront of safe and effective weight management to improve the health and life quality of many over and underweight people.
The TargEDys research team at the INSERM lab of Rouen University has identified a novel mechanism of appetite regulation involving bacterial, hormonal mimetic, proteins that are found naturally in the gut microbiome. This mechanism acts as the basis of TargEDys’ two technologies: ProbioSatys™ and ProbioNutrys™, which respectively moderate the appetite of overweight people and restore the appetite of elderly, cachexic or anorexic people.

Both studies were looking at preclinical validation of Hafnia alvei HA4597 as potential probiotic for appetite and body weight management on overweight and obesity. First study was published in International Journal of Obesity (https://doi.org/10.1038/s41366-019-0515-9), the second in Microorganisms (https://doi.org/10.3390/microorganisms8010035)Read more
The human microbiome is the genome of our microbes. It is 150 times more diverse than our human genome and formed of 5000-different species of bacteria living all over our bodies, especially our gut, mouth and skin. This symbiotic bacterial community is vital for day-to-day bodily functions such as immunity, defence against pathogens, host nutrition, synthesis of vitamins, fat storage and influencing human behaviour. An imbalance in one’s microbiome has been linked to a range of diseases such as Diabetes, Cancer and Obesity. A key step to unlocking the potential of many microbiome based treatments is to fully understand the microbiome and its interactions with the human host.
The gut-brain axis is the bidirectional communication between the central and enteric nervous systems, linking the emotional and cognitive centres of the brain with peripheral intestinal functions. Gut microbiota are very important in influencing these interactions. TargEDys® has discovered a new mechanism of appetite regulation that involves this axis and has developed two types of innovative technology for the treatment of over and underweight patients, ProbioSatys™ and ProbioNutrys™ respectively.
After a meal, intestinal bacteria feed on the ingested food and begin to multiply. During this growth phase, the bacteria produce various signals that allow them to interact with the brain. One such signal is the protein ClpB, produced by Enterobacteria naturally present in the intestines. ClpB has been identified as a mimetic of the satiety hormone (α-MSH) that regulates food behaviour at both peripheral and central levels.
When released, ClpB directly stimulates the enteroendocrine L-cells of the intestine to produce satiety hormones. ClpB also enters the bloodstream to act on satiety regulation in the central nervous system by mimicking α-MSH. The resulting effect is the feeling of satiety or fullness after a meal.
The basis of the ProbioSatys™ technology is an Enterobacteria probiotic strain that produces satiety protein, ClpB.

• Decrease of food intake
• Improvement of body composition
• Activation of lipolysis
• Activation of central satiety pathways
Hafnia alvei 4597, the probiotic strain used in ProbioSatys®, is a commensal bacterium from the Enterobacteriaceae family, naturally present in the human gut. Hafnia alvei 4597 expresses a protein of interest in the regulation of hunger called caseinolytic peptidase B protein homologue (ClpB). It can also be found in a wide range of traditional foods.
Hafnia alvei was first identified in 1954 in raw milk, and has since been found in traditional cheeses with strong flavours such as Camembert and Livarot. Dairy product contamination during the 1990s led the industrialists to pasteurise their milk, which meant losing the typical aromas appreciated by cheese lovers. Hafnia alvei is now added to pasteurized cheese as a lactic ferment to restore its original flavour.
Hafnia alvei adheres to the intestinal mucosa and resists fasting digestion. It is multiple, and is metabolically active in the colon. Its genome has been fully sequenced and it does not have a plasmid with antibiotic resistance genes. The manufacturing process of Hafnia alvei has been specifically developed for TargEDys.
TargEDys is currently demonstrating the efficacy of another hormone mimetic technology that exploits the gut-brain axis to improve the appetite of anorexic, cachexic or elderly patients.
EnteroSatys® contains Hafnia alvei 4597 strain, zinc and chromium which contribute to a healthy metabolic equilibrium*. Hafnia alvei 4597 is a lactic ferment strain, originally isolated from raw milk cheese. The strain has been studied for many years at the National French Medical & Health Research Institute (INSERM) labs in Normandy.
*Zinc contributes to normal lipid and macronutrient metabolism. Chromium contributes to normal blood glucose levels.
To ensure efficacy of the product, EnteroSatys® is manufactured in DRCAPS™ gastro-resistant capsules.

Role of the Gut Microbiota in Host Appetite Control:
Bacterial Growth to Animal Feeding Behaviour
The life of all animals is dominated by alternating feelings of hunger and satiety — the main involuntary motivations for feeding-related behaviour. Gut bacteria depend fully on their host for providing the nutrients necessary for their growth. […] This Review analyses the data relevant to possible involvement of the gut bacteria in the regulation of host appetite and proposes an integrative homeostatic model of appetite control that includes energy needs of both the host and its gut bacteria.Read more
