The pharmaceutical giants piled up and aimed at the extraterrestrial gold field
With the help of capital, the application of the treatment and diagnostic direction of the excreta has also moved rapidly from the laboratory stage of research, ushering in a new wave of industrial cooperation and becoming the next gold race for the males. The excretion industry has flourished in europe and the united states of america, and to date there are more than 40 companies worldwide that treat and diagnose the excretion。
List of surgical companies
In june 2020, yoyo, takeda and bayer announced a deal of up to $2 billion with the company. Among these is a $1. 2 billion cooperation agreement signed with evox therapeutics in the united kingdom, in which future parties will use the evox-specific drug delivery platform to develop effective delivery vectors of rna-disturbing and anti-wilderary nucleotide drugs for treatment of nervous system diseases。
On 18 february of this year, evox therapeutics, based in the united kingdom, raised £69. 2 million (approximately $95. 4 million) from orbimed and google winds to advance its endocrine therapy into clinical trials, focusing on rare diseases that can be treated with protein or rna。
Many biotechnology companies around the world compete for the development of excreta, such as exosomics, carmine therapeutics, vesigen therapetics, mantra bio and aruna bio. In recent years, a number of international pharmaceutical giants have also been involved in this field, and roche, takeda and koji have, respectively, worked with companies with this innovative technology platform to develop endocrinological targeting therapy. This area may be experiencing a boom in the coming years, stimulated by increasing financial support from investors. It is hoped that, as research is carried out and technology advances, rapid progress and new breakthroughs can be made in the study of the excrete as a drug carrier。
Surgical market/clinical application
As one of the "three poles" in the liquid field, the excretion is considered to be an important vector of intercellular communication, diagnosis of disease and pre-circumulation of biological markers, which regulate the biological activity of receptor cells through their carrying of lipids, nucleic acids, proteins, mirna, etc., and thus participate in the biological processes of body immunisation, cell transfer, tumor invasion, antigen submission, etc. There is ample evidence of the potential of the excretion and its contents to become a new diagnostic marker, showing highly promising research value in clinical and therapeutic terms。
The application of the excretion to tumours is very promising. At the liquid detection level, the excretion is relatively accessible and carries sufficient biological information to carry early signs of tumours and provide an opportunity for early diagnosis. In the case of patients in the middle and late stages, the excretion can be used for therapeutic marker prediction, helping clinical choice of treatment options, while providing dynamic monitoring during treatment to help better benefit。
The combination of the excretion and the membrane can transmit the substance and signal carried to the receptor cell and alter its biological function, so the excretion is a potential vector for nanopharmaceutical delivery or gene therapy. Survivors can also be used as vectors for the delivery of drugs, to be targeted and used for the delivery of therapeutics, thereby expanding the delivery of existing precision treatments。
The previous study found that the excretion of the excretion can be spontaneousally concentrated in the liver, so that the drug-borne excretion has great potential for use in treating liver-related diseases such as in situ liver cancer, liver failure, liver fibrosis and fat liver. There is limited potential for physical excretion separation to be directly treated as a drug, but the composition required for natural excretion is mixed into synthetic lipids or nanoparticles, and there is greater potential for application in pharmacology using a controlled assembly of engineering excrete simulations。
Excretion separation extraction
The study of the content of the excretion is premised on the high quality of its extraction, which is hampered by the difficulty of purification due to the small particle size of the excretion and its mixing with a variety of other biological molecules。
In recent years, researchers have developed a variety of separation purification methods based on the physiology of the excretion: hypervelocity centrifugal method, hypervelocity centrifugal method of density gradients, hyperfiltration method, polypolymers deposition method, immunomagnetic bead method, reagent box separation method, etc., are commonly used。
In the case of the separation of the excretion, the first concern is the quality of the excretion, including the assessment of purity, cystic state, success rate and repetition, and then the choice of technical routes。
The hypervelocity centrifugal method is the most commonly used means of purification of the excretion, and the most frequently cited method is currently published, using low-speed centrifugal and high-speed centrifugal alternations, which can be separated from cystic particles of similar size。
Advantages: no special reagents, simple operations, suitable for large-scale samples。
Disadvantages: time-consuming, relatively low purity, unstable recovery rates, repeated centrifugal damage to the excreta, high equipment requirements。
The hypervelocity centrifugal method of the diaphragm gradient is the hypervelocity centrifugal force that causes the sugar cane solution to form a dense segment from low to high continuous distribution and is a zone separation method. Through the density gradient centrifugal, the excretion in the sample will be concentrated in the density range of 1. 13-1. 19g/ml。
Advantages: relatively high purity, suitable for mass samples。
Disadvantages: cumbersome steps, time-consuming, unstable recovery rates, repeated centrifugal centrifugal damage to the excreta and high equipment requirements。
The ultrafiltration method is the filtering of solvents and small molecules to the other side of the film, while the relatively large molecules are amputated on the ultrafiltration for the purpose of separation。
Advantages: simple and efficient, without affecting the integrity of the body。
Disadvantages: the excreta can be blocked, leading to shorter life spans of membranes, lower separation efficiency and purity. In addition, there are adhesives among the excrets left on the membranes, resulting in lower yields。
The thiopolymers are separated and purified by co-deposition or reverse screening, based on the physicochemical properties of the compound and the excrete。
Advantages: simple operation, short time, unequipped。
Disadvantages: low purity, presence of false positives (more proteins or some irremovable polymers), damage to mechanical or chemical additive excretion, and possible interference with downstream analysis by polymers in separations。
Antibody prosthesis and (magnetic beads) methods using a single cloned antibody ball to combine the excretion body, which has its distinctive markers (e. G. Cd63, cd9 protein) on the surface of the excretion body, which can be adsorbed and separated by a package of anti-marked antibody magnets incubated with the excrete cyst。
Advantages: high purity, good specificity and repetition, simplicity of operation, no equipment restrictions。
Disadvantages: lower efficiency and recovery rates, capture of only target excretion bodies that express specific antigens, vulnerability to ph and salt concentrations, and greater impact on cystic integrity。
In the light of the above, the deficiencies in the excretion bodies extracted by the methods available are the low rate of collection, the length of time spent, the low purity level and the incompleteness of the excretion cysts。
In the light of the above, the reagent kit developed by wuhanhuamei biology engineering ltd. Provides a simple and reliable method of extracting the whole excreta from the plant from cell culture, serum, plasma, lotion, urine, saliva, yeast. The excretion cysts extracted from the product are suitable for downstream mirror analysis, nta analysis, nanofcm analysis, western blot, fluorescent ration (qpcr) and high flux sequencing applications。
The reagent box separates the excretion by proteinological prosthesis, which can be efficiently extracted from various types of samples with high purity and complete cystic structure, with the advantages of simplicity, stability and operation:
Future prospects for the excretion
Excretion research has slowly evolved into a rapid development in molecular medicine. Survivors have very bright applications in clinical medicine, mainly because they contain rich biomarkers that can be used to monitor clinical state, diagnose disease, treat response, progress of disease, etc. Important and influential areas of excreta research will evolve with the development of efficient excreta separation technologies。
The use of excreta as biological markers for disease diagnosis has also contributed to research into the treatment of excreta as targets or the use of the excreta itself as a therapeutic tool. Clinical research on the use of excreta as a therapeutic tool is under way, with the aim of studying the safety and effectiveness of excreta in the treatment of patients themselves, whether in msc or in health donors. Under this trend, the use of endocrines as a drug delivery system as a potential vehicle for gene therapy is likely to become more widespread. The immune activation and immunosuppressive function of the excretion body in cancer is expected to produce an anti-cancer vaccine。
The potential application of the excreta as a disease diagnostic marker relies on technological breakthroughs in the excreta-based drug delivery system, which theoretically detect dna sequence variations, rna expression changes, protein changes, etc. Large-scale industrial production of the excrete remains a major challenge to its use for clinical treatment. First, the specific synthesis mechanisms and functional knowledge of the excrete are not very detailed. Second, there are challenges in excretion separation techniques, separation volumes and detection techniques, and oncology applications need to be strengthened and in-depth research. However, while current endocrine biology is still premature, increasing interest and funding will accelerate the progress and clinical transformation of basic endocrine research。
