The invention relates to a composition comprising apolactoferrin, optionally in admixture with lactoferrin, carried via liposomes, as well as to products comprising such a composition, and to their use for the prevention and/or treatment of the conditions affecting the respiratory system, in particular the viral infections.

Milk fat globule membrane (MFGM) phospholipid compositions, methods of preparing and using the MFGM phospholipid compositions, liposomes comprising the MFGM phospholipid compositions, and methods of preparing and using the liposomes comprising the MFGM phospholipid compositions. In various examples, a MFGM phospholipid composition is formed by sequential supercritical carbon dioxide (SC—CO.sub.2) extraction of a milk product and extraction of the remaining milk product with a polar compound-modified SC—CO.sub.2 extraction, where the extract is the MFGM. In various examples, the MFGM is used to prepare liposomes. In various examples, the liposomes are prepared by expansion of a supercritical solution comprising the MFGM composition. In various examples, the liposomes are used to administer a cargo, such as, for example, hydrophilic compound(s), hydrophobic compound(s), amphiphilic compound(s), or the like, any one or all of which may be therapeutic agent(s), nutrient(s), bioagent(s), or the like, or any combination thereof to a subject.

Methods of decreasing muscle atrophy and/or promoting muscle regeneration in a subject at risk of muscle atrophy comprise orally administering a nutritional composition comprising at least one of protein, fat and carbohydrate, and bovine milk-isolated exosomes comprising intact exosomes. In specific embodiments, the subject suffers from malnutrition, acquired immune deficiency syndrome (AIDS), cancer, diabetes, chronic obstructive pulmonary disease (COPD), amyotrophic lateral sclerosis (ALS), non-alcoholic fatty liver disease (NAFLD), or a burn injury, or has undergone clinical corticosteroid treatment.

Bovine milk-isolated powdered exosomes comprise intact exosomes. Nutritional compositions comprise protein, carbohydrate, and/or fat, and exosomes isolated from bovine milk. A method of preparing powdered exosomes comprises centrifuging bovine milk to form a lipid fraction top layer, a whey fraction middle layer, and a first pellet of cells and debris, separating the whey fraction and centrifuging the separated whey fraction to remove additional fat, casein aggregates and debris and form a substantially clear whey fraction, microfiltering the substantially clear whey fraction to remove residual debris, centrifuging the microfiltered whey fraction to obtain a pellet containing exosomes, incubating the exosome-containing pellet in aqueous medium to dissolve the pellet without disrupting exosome membranes to provide an exosome suspension, and drying the suspension to obtain the powdered exosomes. Methods of lowering a risk of developing, or treating, insulin resistance, prediabetes, or diabetes in a subject employ exosomes

The present invention relates generally to pharmaceutical formulations. Particularly, the present invention relates to a new delivery system for delivery of medical components to the lungs, and its utility in the fields of pharmaceutical formulation, drug delivery, medicine and diagnosis.

Cargo-loaded vesicles and compositions comprising such vesicles for oral delivery are provided, wherein the vesicles comprise one or more components from milk purified vesicles. Methods for producing such cargo loaded vesicles are also provided.

Provided herein are methods of encapsulating molecules in milk fat globules and oleosomes, and compositions and pharmaceutical formulations of compositions with molecules encapsulated in milk fat globules and oleosomes.

A method of obtaining an exosome-enriched product comprises providing a whey-containing bovine milk fraction, conducting a first centrifugation of the whey-containing bovine milk fraction to obtain a whey middle fraction, conducting a second centrifugation of the whey middle fraction at an increased speed to obtain a concentrated whey fraction, filtering the concentrated whey fraction to obtain a filtered whey fraction, and conducting a third centrifugation of the filtered whey fraction at a further increased speed to obtain an exosome-enriched product. The exosome-enriched product comprises intact exosomes and less than 5 wt % casein based on the total weight of protein in the exosome-enriched product. Nutritional compositions comprise protein, carbohydrate, and/or fat, and exosomes provided by addition of the exosome-enriched product. A method of improving insulin sensitivity in a subject comprises administering a nutritional composition comprising the exosome-enriched product.

New proteophospholiposomes contain HDL-like vesicles with a new composite of anionic polypeptides, selected from the group of apoproteins A and at least one anionic polypeptide from the group of albumins, transthyretin-prealbumins and at least one cysteine group. The new anionic polypeptide composite is coated with layers of acyl-phosphatidylcholines that are protected from conversions by means of thio-phosphatidylcholines. The thiogroups attract antioxidants, ionic micromaterials and cofactors and are protected by exterior layers that contain neutral lipids and/or by means of capsules that contain microsomes, in an outwardly uniform fashion.

The present disclosure provides milk vesicles as drug delivery vehicles, compositions comprising a therapeutic agent encapsulated within or otherwise associated with the milk vesicles, methods of producing such milk vesicles and compositions thereof, as well as methods of delivering such milk vesicles and compositions to a specific patient tissue or organ. Also provided herein is a composition comprising milk vesicles, wherein the milk vesicles comprise a lipid membrane to which one or more proteins are associated, and wherein (a) a relative abundance of casein in the composition is less than about 40%, and/or (b) a relative abundance of lactoglobulin in the composition is less than about 25%.
