This invention discloses an in vitro maturation culture medium for ferret oocytes and its preparation method, belonging to the field of animal embryo engineering technology. It comprises the following components: TCM199 basal culture medium, 50 mL fetal bovine serum, 25 IU follicle-stimulating hormone, 25 IU luteinizing hormone, 0.5 mg 17β-estradiol, 0.005 mg epidermal growth factor, 12.1 mg sodium pyruvate, 0.2 mM cysteine, 0.1 mM cysteine, 0.030 g penicillin, 0.025 g streptomycin sulfate, as well as an antioxidant complex, a combination of growth factors, and extracellular matrix components. This invention provides a comprehensive and suitable nutritional environment for ferret oocytes by precisely formulating a composite culture medium containing multiple key components. Specifically, the hormone combination at specific concentrations accurately simulates the in vivo physiological environment, effectively regulating the oocyte maturation process; multiple growth factors work synergistically to promote oocyte growth, development, and differentiation; and the addition of the antioxidant complex effectively eliminates free radicals generated during in vitro culture, reducing oxidative stress damage to oocytes.

This invention discloses a recombinant 2-O-sulfonyltransferase mutant and its preparation method, belonging to the field of biotechnology. The recombinant enzyme sequence is formed by fusing a truncated (E28~N356) mutant of hamster-derived 2-O-sulfonyltransferase (L119V-R188E-A240I) with an N-terminal maltose-binding protein (MBP) tag. The recombinant 2-O-sulfonyltransferase mutant exhibits higher activity, 1.9 times that of the recombinant wild type, and greater stability, retaining 86.6% of its activity after 5 days at room temperature. Furthermore, the soluble expression level of this recombinant mutant 2-O-sulfonyltransferase is increased by 5 times. This mutant, as a novel biocatalyst with high efficiency, stability, and controllable production costs, has significant application value and broad industrialization prospects in the industrial enzymatic synthesis of glycosaminoglycans such as heparin and heparan sulfate.

A solution has been discovered that provides a more effective Coronavirus vaccine. The solution is an mRNA vaccine encoding a SARS-CoV-2 nucleoprotein (N) (mRNA-N) in combination with an mRNA vaccine encoding SARS-CoV-2 spike protein(S) (mRNA-S). Chemically modified mRNA-N (pseudouridine) and / or chemically modified mRNA-S (pseudouridine) can be synthesized and packaged in lipid nanoparticles (LNP). In mouse and hamster models, it was shown that mRNA-N alone is immunogenic and can significantly diminish viral loads in the mouse lung after prime-boost intramuscular immunization. In addition, the combinatorial mRNA-N / mRNA-S vaccination induces substantially stronger protection against SARS-CoV-2 than vaccination with mRNA-S alone.

The disclosures of the invention arc directed to the manufacture of effective, affordable vaccines that arc globally accessible. Using a platform conjugation technology, highly immunogenic conjugate vaccines were produced that elicit broad cross-neutralization to variants of concern (VOC), manufactured cheaply compared to mRNA vaccines. Protein-protein conjugates and Toll-Like Receptor (TLR) agonist adjuvants were shown to enhance immunogenicity and induce broad cross-protection against VOC, a characteristic lacking in early mRNA CO VID-19 vaccines. Murine nAb titers from Beta-only conjugates were equivalent between Beta, Delta, Omicron BA.l, BA.2, and BA.4 / BA.5, which were circulating up to three years after the antigenic strain. Additionally, Beta-Delta bivalent conjugate vaccines readily prevented disease in hamster challenge, which demonstrates a vaccine with remarkably broad cross-protection and potential to protect for extended periods despite mutations, without requiring expensive boosters or antigen adaption. This vaccine can be produced in our highly automated, large-scale manufacturing facility enabling economical production of inexpensive, effective vaccines for high-need areas.

The invention provides a method for preparing inhalable targeted gold nanoparticles for accelerating pulmonary delivery and treating pulmonary inflammation. The method comprises the following steps: preparing plasmids; carrying out plasmid transformation; carrying out protein expression induction; carrying out protein purification; and the gold nanoparticles (Au (at) PEG-RBD NP) combined with the spikes RBD are prepared. Nanoparticles (NP) in air accumulate more readily in lungs with lipopolysaccharide-induced acute respiratory distress syndrome (ARDS) than in healthy lungs and enter alveolar epithelial cells that express angiotensin converting enzyme (ACE) 2 and L-SIGN (both are Spike receptors activated in ARDS hamsters). The nanoparticles (NP) treat tissue damage, oxidative stress, and inflammation more effectively than corticosteroids, and do not remain gold or create toxicity in the major organs one year after inhalation. The gold core can be used for inhibiting p38 alpha mitogen activated protein kinase and polo-like kinase 3. Similar therapeutic effects have been observed in hamsters suffering from hydrochloric acid induced ARDS. This self-therapeutic nanoparticle (NP), when combined with biomimetic and non-invasive delivery, provides a safe, efficient, and targeted treatment for lung inflammation.
