- the invention concerns the bacterial strain Limosilactobacillus mucosae deposited with the CNCM under accession number CNCM 1-5661.
- FIG 1 represents the concentration of GLP-1 in the supernatant of intestinal neuroendocrine cells from SCT-1 mice after 4 hours of incubation in the presence of the different bacteria and conditions tested.
- the abscissa axis represents the different conditions tested, namely, from left to right: strain 1 (L. casei 7), strain 2 (L. casei 2), strain 3 (L. camelliae), strain 4 (L. salivarius), strain 5 (L. rhamnosus), strain 6 (L. reuleri), strain CNCM 1-5661 (L. mucosae) and control (negative - in sterile cell medium).
- the y axis provides the GLP-1 concentration in pg/mL.
- FIG 2 represents the concentration of GLP-1 in the supernatant of intestinal neuroendocrine cells from SCT-1 mice as a function of the incubation time in the presence of the strain CNCM 1-5661 (L. mucosae).
- the abscissa axis represents the incubation time, namely, from left to right: 3 hours of incubation, 4 hours of incubation and 5 hours.

- FIG 3 represents the concentration of GLP-1 in the supernatant of intestinal neuroendocrine cells from SCT-1 mice after 3 hours of incubation in the presence of different bacteria of the species L. mucosae at different bacterial concentrations.
- the abscissa axis represents the different conditions tested, namely, from left to right: the control (negative control, sterile cell medium), the Lacticaseibacillus casei strain (strain A - negative control, ⁇ 5.10 9 CFU/mL), the strain CNCM 1-5661 (strain B - positive control, -5.10 9 CFU/mL), strain CNCM 1-5661 diluted 1/10 (strain B diluted - -5.10 8 CFU/mL), strain DSM 13345 (strain C - -2.10 9 CFU/mL), strain DSM 13345 diluted 1/10 (strain C diluted - -2.10 8 CFU/mL), strain DSM 13346 (strain D — 4.10 9 CFU/m
- the y axis provides the GLP-1 concentration in pg/mL. Significant difference (P ⁇ 0.05). Same comment as above, there is a clear difference between the total absence of secretion detected (for the negative control conditions) and the detectable secretion of GLP-1 in the conditions with Z. mucosae bacteria, all strains combined, but no statistics were calculated (not enough data) and did not seem necessary for the results.
- FIG 4 represents the weight of the muscles of the hind leg of rats (in mg/g of rat) for different groups of aged rats (20 months) after one month of study.
- the groups of rats studied are, from left to right, on the x-axis: rats fed ad libitum (AL), rats restricted to 75-80% of ad libitum (R), rats restricted and supplemented in Z. mucosae strain CNCM-I5661 (R+L mucosae 15561), rats restricted and supplemented with Z. casei (R+L casei).
- the inventors have carried out in-depth work to identify the capacity of a species of bacteria, the Limosilactobacillus mucosae species, to treat and/or prevent disorders requiring an increase in the production of GLP-1 in a subject in need. .
- Limosilactobacillus mucosae is abundant in patients with short bowel syndrome (Joly et al, biochemistry 2010; PMID: 20172013) and is capable of colonizing a tract virgin digestive (axenic animal) after fecal transfer (Gillard et al; Front Physiol. 2017); this indicates that this species is a digestive tract commensal.
- This ability of Limosilactobacillus mucosae to increase the synthesis of the intestinal peptide GLP-1 and to be present in the digestive tract is important because this peptide has numerous metabolic pleiotropic effects in the host, in particular, it improves insulin secretion. by the pancreas, promotes glucose tolerance and therefore optimizes/improves the energy and nitrogen metabolisms of the host.
- the inventors showed that the administration of a strain of Limosilactobacillus mucosae made it possible to increase muscle mass in a sarcopenic rodent model.
- the present invention relates to the use of a bacterial strain of the species Limosilactobacillus mucosae, or a lysate or culture supernatant thereof.
- lysate is used interchangeably to designate the entire lysate obtained by lysis of the microorganism concerned or only a fraction thereof.
- Obtaining dead bacterial cells can be carried out by any method known to those skilled in the art.
- the bacterial cell lysate is made up of all or part of the intracellular biological constituents and the constituents of the cell walls and membranes. It contains in particular the cellular cytoplasmic fraction containing enzymes such as lactic acid dehydrogenase, phosphatases, phosphoketolases and transaldolases.
- the constituents of cell walls are in particular peptidoglycan, murein or mucopeptide and teichoic acid and the constituents of cell membranes are composed of glycerophospholipids.
- a bacterial cell lysate can be obtained by different technologies, such as for example by exposing bacterial cells to osmotic shock, thermal shock, or ultrasound. More particularly, this lysate can be obtained according to the technology described in US patent 4,464,362.
- culture supernatant is meant within the meaning of the present invention the culture medium in which the bacterial strains remained during their cultivation, which can also be designated by the term “extracellular medium” in the present description.
- the culture supernatant may include the metabolites produced and secreted by the bacteria, also called extracellular metabolites. Examples of metabolites are, for example, peptides, glycopeptides or lipopeptides produced by the bacteria.
- the culture supernatant can be crude or have undergone one or more steps to filter it, concentrate it, freeze-dry it, heat it, etc. These techniques for transforming the culture supernatant of a bacteria are known to those skilled in the art.
- the composition of the culture supernatant varies depending on the conditions and cell culture methods of the bacterial strain. It mainly includes extracellular metabolites when the biomass is growing or only active. But also potentially intracellular metabolites for cultures at the end of the stationary phase and when microbial lysis is significantly greater. A portion of the cells died and some lost their membrane integrity during lysis, as a result of which the supernatant will include cell walls from dead cells but also intracellular metabolites.
- the culture supernatant may also include bacterial cells of the species Limosilactobacillus mucosae, in living or dead form.
- Limosilactobacillus mucosae is a rod-shaped bacterial species of lactic acid bacteria first isolated from pig intestines. It exhibits mucus adhesion activity.
- Limosilactobacillus mucosae is a strictly anaerobic gram-positive bacterium, which can however multiply to a reduced extent in the presence of oxygen.
- This bacterial species is described in particular by Roos et al. (2000, International Journal of Systematic and Evolutionary Microbiology, Vol. 50 (1): 251-258).
- This bacterial species is described in the human microbiota of patients with short bowel syndrome (Drastic changes in fecal and mucosa-associated microbiota in adult patients with short bowel syndrome. Joly F, Mayeur C, Bruneau A, Noordine ML, Meylheuc T, Langella P, Messing B, Duée PH, Cherbuy C, Thomas M.Biochemistry 2010 Jul;92(7):753-61)

- the bacterial strains of the species L. mucosae are in a living or dead form, preferably in a living form.
- dead bacterial strain we mean, within the meaning of the invention, a bacterial cell which is definitely no longer capable of multiplying and consequently of forming a colony in culture. Unlike a lysate, a dead bacterial strain can retain all of its membrane integrity.
- a dead bacterial strain can be obtained by any known cell death method.
- the dead bacterial cells according to the invention can in particular be obtained by exposure to high heat (for example by exposure to a UHT protocol).
- living(s) designates living bacterial cells, including stabilized bacterial cells, i.e. i.e. viable and revivable bacterial cells (by all known stabilization methods, for example by freezing, freeze-drying or spray drying).
- compositions The present description also relates to a composition comprising a bacterial strain of the species Limosilactobacillus mucosae, or a lysate or culture supernatant thereof.
- a bacterial strain according to the invention is included in a composition comprising a physiologically acceptable medium.
- physiologically acceptable medium are intended to designate a medium which is compatible with the organism of the individual to whom said composition must be administered.
- This may be, for example, a non-toxic solvent such as water.
- the medium can also be a food, in particular when the bacterial strain according to the invention is included in a nutritional composition, as defined below.
- the medium may also be a mucus, such as snail mucus.

- a composition according to the present description consists of a pharmaceutical composition when it is intended to prevent or treat dysregulation of insulin sensitivity and/or blood sugar, as in the case of diabetes or prediabetes. .
- a composition comprising a bacterial strain of the species L. mucosae does not differ in its characteristics general conditions set out in the description, depending on whether it is a nutritional composition or a therapeutic composition.
- a pharmaceutical composition is distinguished from a nutritional composition by the fact that the pharmaceutical composition has, in the subject to whom it is administered, a preventive effect and/or a treatment effect for a disease.
- Each of these compositions also meets its own regulations and is distinguished by their mode of action. Indeed, pharmaceutical compositions exert a “pharmacological, immunological or metabolic action”; while nutritional compositions have a “nutritional or physiological” effect.

- Dysregulation of insulin sensitivity such as the appearance of insulin resistance, or insulin resistance, describes a situation where liver, muscle and fat cells, for example, become resistant to insulin. There is then less glucose entering these cells and it remains in the blood. In response to insulin resistance, pancreatic insulin-secreting cells tend to produce more insulin (hyperinsulinemia) and may eventually become exhausted. Insulin production then becomes insufficient and the blood glucose level becomes too high (hyperglycemia). Insulin resistance can also involve other metabolisms regulated by insulin such as protein metabolism. Indeed, insulin, combined with meals, is a major stimulator of muscle protein anabolism. Insulin resistance therefore contributes to muscle wasting due to a lack of anabolism in the muscle, particularly when eating a meal.
- Blood sugar regulation is the process by which the level of glucose in the blood, known as blood sugar, is kept close to a value that is beneficial for the body. This regulation is part of the processes for maintaining homeostasis within the body. Normal fasting blood sugar in humans is statistically between 0.70 and 1.10 g/L. When blood sugar levels are abnormally higher or lower than this threshold, we speak of dysregulation.
- the main disorders linked to dysregulation of insulin sensitivity and/or blood sugar according to this text are prediabetes, type 1 diabetes and type 2 diabetes. They may or may not be caused by obesity.
- the activation of receptors expressed at the level of insulin cells (P) and certain peripheral tissues by GLP-1 stimulates insulin secretion (insulinotropic effect) but also activates the transcription of the insulin gene and increases insulin biosynthesis and inhibits the release of glucagon (static glucagon effect).
- prediabetes we mean a physiopathological state characterized, in particular, by high blood sugar levels compared to normal, but below the threshold for defining type 2 diabetes. Fasting blood sugar levels are considered to be (i) normal between 0.70 and 1.10 g/1, (ii) sign of prediabetes between 1.10 and 1.25 g/1 and (iii) sign of diabetes when > 1.25 g/1. Prediabetes generally does not cause symptoms, but is often associated with obesity, dyslipidemia, and hypertension. It is a risk factor for cardiovascular diseases. Prediabetes is characterized, in particular, by glucose intolerance.
- GLP1 Stimulation of insulin and glucagon secretion by the pancreas by GLP1 controls glycemic excursions, by reducing fasting blood sugar. GLP1 induces glucose uptake and hepatic storage and inhibits gluconeogenesis. Furthermore, and in addition to increasing insulin secretion, GLP1 also plays a role in improving insulin sensitivity in many tissues, including muscle (Muller et al., 2019, Mol Metab).
- type 1 diabetes or “DTI”, we mean a chronic disease which is characterized by the total absence of insulin production in an individual. The person living with type 1 diabetes therefore depends on daily insulin injections or an insulin pump to ensure their survival.
- GLP1 plays many roles in blood sugar control, including controlling the stimulation of insulin and glucagon secretion, glucose uptake and hepatic storage, inhibition of gluconeogenesis, and improvement of insulin sensitivity of many tissues.
- type 2 diabetes or “T2D”, we mean a chronic disease which occurs when the pancreas does not produce enough insulin (blood sugar regulating hormone), or when the body is not able to use the insulin it produces effectively.
- the disorder linked to the dysregulation of blood sugar is type 2 diabetes.
- the disorder to be prevented and/or treated is a loss of muscle mass and/or function, characterized in that the subject in need is chosen from among elderly subjects affected by sarcopenia, subjects in overweight and obese subjects affected by sarcopenic obesity and subject to a diet, subjects affected by cachexia, in particular linked to cancer, inflammatory bowel disease or chronic obstructive pulmonary disease, immobilized subjects , diabetic or prediabetic subjects, “serious burn” subjects, septic or having suffered a viral infection, convalescent and/or immobilized subjects, and subjects having undergone intestinal resection or presenting intestinal malabsorption.

- Subjects who have lost muscle mass in the above-mentioned states are generally resistant to the anabolic action of the meal and/or the action of insulin. If subjects experiencing significant muscle wasting are often insulin-resistant, not all insulin-resistant or prediabetic subjects are necessarily in a situation of muscle wasting, which is a phenomenon that can set in gradually over time, with muscle wasting. and the development of insulin resistance strongly linked metabolically (Daily and Park, 2022 Cells - DOI: 10.3390/cells 11030338)
- GLP-1 has advantageous properties making it possible to optimize the energy use of nutrients and limit muscle wasting (Hong et al., Journal of Cachexia, Sarcopenia and Muscle 2019; 10: 903-918 ), particularly in insulin-resistant individuals (Massimo et al., The Impact of Glucose-Lowering Drugs on Sarcopenia in Type 2 Diabetes: Current Evidence and Underlying Mechanisms. Cells 2021, 10, 1958).
- the loss of muscle mass can be measured by different technologies known to those skilled in the art such as for example upper arm circumference, bioelectrical impedance, bioenergetic X-ray sorptiometry (DXA) and CT scanning (Mareschal et al, 2019 Journal of Clinical Medicine, doi: 10.3390/jcm8071040).

- locomotor difficulties e.g. absorption, digestion, excretion, tissue and organ dysfunction
- reduced resistance to external aggressions e.g. absorption, digestion, excretion, tissue and organ dysfunction

- elderly subject in the case of a feline, in particular a cat, we mean a subject over 13 years old.
- Sarcopenia (a word from the Greek which can be translated as “lack of flesh”), initially defined by a loss of skeletal muscle mass, is currently characterized by a loss of muscle mass associated with functional degradation (European Working Group on Sarcopenia in Older People (EWGSOP) - Cruz Jentoft et al, 2019 Age and Aging). After building up to the age of 20 to 30, muscle mass decreases by about 1% per year, even in healthy people. This process accelerates between the ages of 50 and 60. Sarcopenia impacts physical performance, promotes walking disorders and constitutes a factor of fragility and increased risk of dependence, particularly in the elderly.
- sarcopenia does not only affect the elderly but also insulin-resistant populations such as the obese, we therefore speak of sarcopenic obesity (Working Group from European Society for Clinical Nutrition and Metabolism (ESPEN) and European Association for the Study of Obesity (EASO) - Donini et al, 2022, Obesity Facts).
- This muscle wasting can also occur over shorter periods of time, particularly in intense catabolic situations such as cancers and associated powerful treatments such as chemotherapy. In this case, we rather speak of cachexia (see below).
- Sarcopenia is associated with an increased risk of falls and fractures leading to immobilization which, in turn, aggravates sarcopenia. We are thus witnessing a “snowball” effect amplifying the loss of muscle mass and function linked to age.
- obese is meant a physiopathological state in which an individual presents, in particular, weight gain and excess adipose tissue, generally induced by an obesogenic diet, including, in particular, excessive consumption of high-calorie foods, genetic predispositions or insufficient or non-existent sports practice.

- an “overweight individual” means an individual whose condition is not physiopathological. An overweight individual often also has excess fatty tissue. An individual is generally considered to be overweight when they have a body mass index (BMI) between 25 and 30.
- BMI body mass index
- Cachexia a profound weakening of the body, is characterized in particular by the wasting of adipose tissue and muscles. It is common in many diseases, including cancers that are difficult, if not impossible, to control or cure and, as specified above, occurs over much shorter periods of time (days to weeks). Cancers, particularly those of the pancreas and stomach, cause severe cachexia. Patients can lose 10 to 20% of their body mass. Cachexia can also be linked to other catabolic pathologies such as inflammatory bowel disease or chronic obstructive pulmonary disease, viral infection or sepsis.
- GLP-1 can help optimize the use of nutrients. Indeed, we see in patients who have undergone intestinal resection, an increased production of GLP1 (Jeppesen et al 2000, Gut; Gillard et al 2017, Front Physiol) making it possible to adapt intestinal motility and optimize metabolism of the host with the least supply of nitrogen and energy nutrients. The repercussions will be particularly notable on the energy (fat mass) and nitrogen (lean mass and muscle mass) stocks of the subjects. An improvement in the intestinal secretion of GLP-1 by these patients, notably via the provision of a GLP-1 secreting probiotic, is therefore favorable in these subjects.
- the subject to be treated is a subject presenting an indication for administration based on GLP-1 receptor agonists.
- An individual with an indication for administration of GLP-1 receptor agonists is an individual suffering from a disorder or disease that can be treated or whose symptoms can be alleviated by administration to said individual. one or more GLP-1 receptor agonists.

- undernourished we mean, within the meaning of this description, a “state of an organism in nutritional imbalance” (See, “Diagnosis of undernutrition in children and adults – Method Recommendations for clinical practice » November 2019, High Authority of Health and French Nutrition Federation), said imbalance being characterized by a negative energy and/or protein balance.
- This definition encompasses a plurality of situations that can lead to a state of undernutrition, such as a deficit in isolated nutrient intake, an increase in expenditure or losses leading to an imbalance. This term also covers subjects with heightened nutritional needs.

- CNCM-I5661 bacteria were cultured in MRS medium (supplier BD, reference: 288130, reconstitution made according to the supplier's instructions), then centrifuged and frozen in the form of dry pellets. The dry pellets were then resuspended in the STC cell culture medium.
- V indicates that the CNCM-I5661 bacteria were cultured in “veganMRS” medium (BIOKAR supplier, reference: BK176HA, reconstitution made according to the supplier's instructions), then centrifuged and frozen in the form of dry pellets. The dry pellets were then resuspended in the STC-1 cell culture medium.
- 61C-10 incubation of STC-1 cells in the presence of the CNCM-I5661 strain.
- ME 10 (10 times more bacteria than STC-1 cells)
- 61C-100 incubation of STC-1 cells in the presence of the CNCM-I5661 strain.
- ME 100 (100 times more bacteria than STC-1 cells)
- 61C-1000 incubation of STC-1 cells in the presence of the CNCM-I5661 strain.
- ME 1000 (1000 times more bacteria than STC-1 cells)
- results shown in the table above indicate a dose effect of the strain and also show that the strain retains its functions even if it is cultivated in another medium.
- the presence of the CNCM-5661 strain induces the production of the enterohormone GLP-1 by STC-1 cells. This production is all the more important as the number of bacteria increases. This production is not observed in the presence of strains of the species Lacticaseibacillus casei, which come from the same patient.
- the pro-GLP-1 effect of the CNCM 1-5661 strain is not dependent on the culture medium used for the cultivation of the strain.
- GLP-1 increased as a function of the contact time between the bacteria of the CNCM 1-5661 strain and the intestinal cells (see Figure 2).
- the bacteria were placed in an acidic medium (pH 2.5 and 3) for 45 and 90 minutes, corresponding to average residence times of the food bolus in the stomach before passing into the duodenum.
- the bacteria showed very good resistance to the gastric medium (composition: HCl, pepsin, NaCl), with no significant difference between the incubation times and the two pHs tested (p > 0.05, Fisher exact test).
- the inventors also tested the survival of bacteria under conditions encountered downstream of the stomach which include the presence of bile salts.
- the survival of the CNCM 1-5661 strain was therefore tested in the presence of bile salts after 1h, 2h, 3h and 4h of incubation at 37°C.
- the bacteria showed very good resistance to bile salts, with no significant difference between incubation times (p > 0.05, Fisher exact test).
- the inventors determined its ability to adhere to human intestinal Caco-2 cells. Determination of the viable number of lactic acid bacteria adhering to intestinal cells has was carried out after 3 hours of contact with Caco-2 cells at an MOI (multiplicity of infection) value of 0.1, 1, 10 and 100.
- the CNCM 1-5661 strain has a satisfactory percentage of adhesion and similar to other microorganisms, without any significant difference between the MOIs tested (p>0.05, Fisher exact test).
- DSM 13345 Three other strains were therefore tested: DSM 13345, DSM 13346, and DSM 102820.
- the strains CNCM 1-5661 (as a positive control) and a strain of L. Casei (negative control, which does not induce the synthesis of GLP- 1) were also used:
- Control sterile cell medium
- strains B to E were diluted 1/10 .
- the results, presented in Figure 3, show that in the presence of all strains of the species Limosilactobacillus mucosae tested, synthesis of GLP-1 by SCT-1 cells was observed. In addition, this production of GLP-1 is dose dependent.
- the inventors measured the capacity of the L. mucosae strain CNCM 1-5661 according to the invention (shown to be capable of inducing the synthesis of GLP-1 by SCT-1 cells in culture) and a strain of the species L. casei outside the invention (non-inducing GLP-1 production) on the muscle mass of a fragile aged rat model.
- the inventors carried out an in vivo study over a period of 1 month on aged rats (20 months) according to the following groups:
- the animals were sacrificed at the end of the experiment, weighed, and the muscles of the hind leg (gastrocnemius, Extensor digitorum longus, Soleus, Tibialis anterior) were excised and weighed. The sum of the weights of these 4 muscles was calculated and reduced to the weight of the animals.
