“Matrioskas” of nanoparticles, a new therapeutic approach against tuberculosis

Researchers of NANBIOSIS U9 Synthesis of Nanoparticles Unit Manuel Arruebo and Víctor Sebastián have participated in a research published in the journal Nanomedicine

Tuberculosis is an infectious disease that poses a serious public health problem and, according to WHO data, 10.4 million people became ill with tuberculosis and 1.7 million died in 2016. Therefore, advance in the development of new tools for diagnosis and treatment is essential and the use of nanoparticles could open a new horizon to deal with the infections caused by Mycobacterium tuberculosis.

In this line, researchers from the CIBER at the University of Zaragoza, and at the Germans Trias i Pujol Research Institute, have demonstrated the superior effectiveness in-vitro after the use of polylactic-co-glycolic acid (PLGA) nanoparticles loaded with rifampin. (one of the drugs used in combination for the treatment of tuberculosis), compared to the effect of the free antibiotic.

Researchers have encapsulated rifampicin in nanoparticles, which in turn have been encapsulated in ‘Matrioskas’ type macroparticles, resistant to the acid pH of the stomach. In this way, the microparticles could be administered orally, a non-invasive way and well accepted by the patient, resist gastric degradation and reach the intestine. There the PLGA nanoparticles loaded with the anti-tuberculosis drug would be released and cross the intestinal wall to reach the systemic circulation and potentially the alveolar macrophages infected by the intracellular pathogen, co-locating the antibiotic-laden nanoparticles with the pathogenic agent. Nowadays rifampicin is administered orally, however it is well known that up to 26% of the dose delivered is degraded in the stomach.

These nanoparticles were able to migrate through an in-vitro epithelial membrane that mimics the intestinal wall and thus be able to fulfill its function of transport and controlled release of the encapsulated drug, which in this way avoids contact with digestive enzymes and with low pH. “This study will lay the foundations for future research based on nanoparticles, aimed at the in vivo evaluation of these nanoparticles with antibiotics in mice infected with tuberculosis,” explains CIBERES researcher José Domínguez.

The researchers of this study initiated their collaboration thanks to the TARMAC project, funded thanks to an initiative of the CIBER-BBN, the CIBERES and the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR). This project focused on the development of new tools for the diagnosis and treatment of infectious diseases of the respiratory tract, particularly tuberculosis.

Researchers of NANBIOSIS U9 awarded for a work on scaffolds for dental regeneration

Researchers Manuel Arruebo and Víctor Sebastián, from the CIBER-BBN group led by Jesús Santamaría (NFP) at the University of Zaragoza, that coordinates NANBIOSIS Unit 9 Synthesis of Nanoparticles, have received the second prize of the Resomer Awards granted by the company Evonik, a international recognition to competitiviness.

Their work “Promoting bioengineered tooth innervation using nanostructured and hybrid scaffolds”, has been published in the journal Acta Biomaterialia 50 (2017) 493-501. In this work, the researchers of the CIBER-BBN manufactured biodegradable materials such as scaffolds to promote dental regeneration. These scaffolds contained an immunosuppressive drug that, in addition to avoiding rejection after implantation, favored innervation. These implants were evaluated in vitro and in vivo at the French National Institute for Medical Research in Strasbourg, in the group of Nadia Jessel, demonstrating in animal models that these implants favored tooth regeneration and that the regenerated teeth were vascularized and innervated, both necessary characteristics to obtain a good regeneration.

The company Evonik AG is one of the largest chemical companies in the world with more than 36,000 workers and chemical plants in more than 30 countries. Its specialty is fine chemistry and one of its flagship products are biodegradable polymers.

Jesús Santamaría, interviewed in the Cadena Ser Radio, denounces the bureaucratic barriers that hinder research.

Jesús Santamaría, Scientific Director of NANBIOSIS Unit 9, Synthesis of Nanoparticles Unit, denounces the bureaucratic obstacles of the Law of Contracts, which are paralyzing the investigations whenever it is necessary to buy material or hire personnel.  His research against cancer, which received one of the most powerful European funding of more than two million euros, is stranded because of this rule, which requires to take out any purchase over 15,000 euros. “You can not do research like that,” Santamaría said. “In other countries there are no obstacles and we have to compete with them”

With the entry into force on March 9 of Law 9/2017 of November 8, scientists encounter importan important problems to use not only their basic budgets but also to use funds obtained in open and competitive calls, so they have money available to investigate that can not be spent.

This situation of Spanish research has been reviewed internationally, for example in an article published by the prestigious journal Science: Accounting rules hobble Spanish institutes 

Until now, spending limits were applied per researcher, project and year. (that is, public tenders or having to submit several budgets). Now the limit is computed at the institutional level. This makes it impossible, in practice, to execute budgets, given that once the border of 15,000 euros per institution is exceeded, the direct contract it is not possible but it is needed to undertake the procedures of a contest which can take months.

But all of this does not happen outside Spain, not even in Europe, even though this law is an adaptation of a European Directive. In the rest of the European Union, Science has been prevented from going through this “funnel”. Santamaria calls for a stronger reaction from the scientific community towards the administration.

These obstacles and their results in the R+D were explained in an article published in El Diario.es on April 4, titled “Why does the government make it difficult to carry out scientific research spending?”: “This measure, which may make some sense for laboratories Hospitals that carry out routine analyzes in a standardized manner are meaningless when we talk about independent research groups that work in very diverse areas within the same center, and that lack the administrative personnel necessary to manage this new form of bidding. make impossible, for example, the execution of expenses in other countries, something as common as the payment to a laboratory in North America for the performance of a chemical or genetic analysis: according to this law the foreign laboratory would have to be submitted to the contest. of billing of this type of services are tiny enough so that a laboratory i International, which is extremely busy with the processing of their samples and the calibration and maintenance of their equipment, bother to start the long and complex path of opting for a public tender so that a Spanish researcher can pay for the analysis of their samples. “

Conference on Nanotoxicity, next May 24, Parc Scientific of Barcelona

NANBIOSIS is organizing a Conference on Nanotoxicity in collaboration with Nanomed Spain and Materplat, next May 24 in the Parc Scientific of Barcelona, to debate about the efect of nanotoxicity of nanoparticles and nanotechnologies in health.

The increase of potential risks to health has created the new discipline of nanotoxicity, that is, the study of the toxicity produced by the effect of nanoparticles and nanomaterials. The objective of this day is to learn more about the lines that are being followed by researchers in the area of ​​nanotoxicity, the progress of different projects in this field, as well as existing tools to know and reduce the toxicity of nanoparticles and nanomaterials.

Nanotechnology intervenes in the design, production and use of structures and objects that have at least one of its dimensions in the scale of 100 nanometers or less. This science is allowing the achievement of advances in various areas with great repercussions for society.

However, manufactured nanoparticles can have properties and effects very different from those of the same materials in conventional sizes, which may pose new risks to the health of man and other species. Some nanoparticles, which are used as a vehicle for drugs to reach the desired cells in greater quantities, to reduce the side effects of the drug in other organs or both, have the same dimensions as certain biological molecules and can interact with them.

The increase of potential risks to health has created a new discipline, nanotoxicity, that is, the study of the toxicity produced by the effect of nanoparticles and nanomaterials.
