What is biopharmaceuticals is introduced as follows:
Biopharmaceuticals are mainly natural biological materials, including microorganisms, human bodies, animals, plants, marine organisms, etc., which are used to make medicines.
Biological drugs are characterized by high pharmacological activity, low toxic and side effects, and high nutritional value. Biological drugs mainly include proteins, nucleic acids, sugars, lipids, etc. Animal raw materials obtained by immunological methods, microorganisms or other cell raw materials obtained by changing the genetic structure, etc. The constituent units of these substances are amino acids, nucleotides, monosaccharides, fatty acids, etc., which are not only harmless to the human body but also important nutrients.

Application of biopharmaceuticals in DNA vaccines for type I diabetes:
DNA vaccines based on the B7-1-PE40KDEL exotoxin fusion gene have recently received international approval "Three-party" invention patent authorization. This achievement is an original achievement with completely independent intellectual property rights. It is also the first international "triparty" invention patent authorization obtained in the field of my country's new therapeutic DNA vaccine. That is to say, this achievement will be sold in the world's three largest markets (the United States, the European Union and Japan) are protected by patents.
Therapeutic DNA vaccines have strong specificity, accurate efficacy, good safety, and low production costs. They have now become another new strategic commanding heights in the global biopharmaceutical industry after monoclonal antibody drugs. According to reports, the DNA vaccine can effectively prevent and treat type I diabetes in early animal experiments, correct the disordered cellular and humoral immune responses of type I diabetes itself, repair damaged pancreatic beta cells, and restore its own insulin secretion.
The vaccine only needs to be injected subcutaneously or intramuscularly into the patient once, and can effectively maintain the efficacy for nearly a month. It will greatly improve the compliance of the DNA vaccine and avoid the trouble of patients taking medication every day.
