Non-Hodgkin lymphoma treatment with protein nanoparticles

A study result of collaboration between researchers of two NANBIOSIS units managed to produce a potent antitumor effect in an animal model with non-Hodgkin lymphoma

A non-Hodgkin’s lymphoma, NHL is a cancer that starts in white blood cells called lymphocytes, which are part of the body’s immune system.
Lymphoma. NHL is a term that’s used for many different types of lymphoma that share some characteristics.  The most prevalent type of non-Hodgkin lymphoma is called diffuse large B-cell lymphoma (LDCGB). Although there are treatments for this pathology, there are non-responders.

This nanoparticle can be developed as a nanopharmaceutical, in order to introduce a new treatment, which could be used in 40 percent of patients with non-Hodgkin lymphoma who do not respond to current therapy, and avoiding the adverse effects associated with conventional treatment.

The research conducted by the CIBER-BBN at the Hospital de Sant Pau, led by Ramón Mangues (Nanbiosis U18 Nanotoxicology Unit) and the Autonomous University of Barcelona, led by Antoni Villaverde Nanbiosis U1 Protein Production Platform (PPP) has demonstrated the high selectivity of a protein-based nanomedicine and created by the researchers themselves, for the targeted delivery of a toxin in the tumor cells to induce their selective death. The objective is that these nanoparticles can be developed as a nanopharmaceutical, which could be used in 40 percent of patients with non-Hodgkin lymphoma who do not respond to current therapy, avoiding the adverse effects associated with conventional treatment

This selective effect of the nanopharmaceutical is due to the specific interaction between a targeting peptide that contains the protein nanoparticle that carries the toxin and the CXCR4 cell receptor that is highly overexpressed in lymphoma cells. This is the first time that the uptake of protein nanoparticles in different organs of a hematological neoplasm is quantified.

This observation has shown that 86 percent of the administered dose accumulates in cancer cells, a substantial improvement compared to other non-protein nanoparticles or other drug targeting systems such as drug-antibody conjugates, which only reach 1 percent of the dose in the tumor.

As Ramón Mangues, Scientific Director of Nanbiosis U18 Nanotoxicology Unit, explains, “the new protein nanoparticle contains a ligand that identifies a CXCR4 receptor on the surface of cancer cells in which it enters selectively, reaching a very high uptake of the tumor and very low in the rest of the body, which greatly exceeds the tumor uptake of drugs used for this type of lymphoma.”

The bioluminescent follow-up of cancer cells and nanoparticle biodistribution and toxicity studies has been performed in the ICTS NANBIOSIS Nanotoxicology Unit Protein production has been partially performed by the ICTS “NANBIOSIS”, more specifically by the Unit of Protein Production Platform.

A Minimally Invasive Microsensor Specially Designed for Simultaneous Dissolved Oxygen and pH Biofilm Profiling

Ana Moya, Xavi Illa, Rosa Villa and Gemma Gabriel, researchers of the Biomedical Application’s Group (GAB) of CIBER-BBN and the Microelectronics Institute of Barcelona, which main interests are the design and fabrication of Micro and Nano Systems for Biomedical Applications, have recently published, in collaboration with other authors an article in the Special Issue Advanced Electrochemical Sensors and Environmental Monitoring

The authors thank in the Acknowledgements the participation of the ICTS NANBIOSIS U8 Micro– Nano Technology Unit of the CIBER in Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) at the IMB -CNM (CSIC)

The work reports the development of a novel multi-analyte microsensor based on MEMS technologies for simultaneous monitoring of DO and pH. Results showed the capacity of microsensors to quantify concentration gradients of di erent species within biofilms. In addition, the possibility of integrating two microsensors, specially designed to obtain a seven-point profile in a single measurement, introduced in this paper for the first time, clearly simplifies the equipment and the procedure necessary to record concentration profiles within biofilms. Critical future prospects have been established

NANBIOSIS Scientific Director, Jaume Veciana, coauthor of an article highlighted in Chemistry Views

Jaume Veciana, Scientific Director of NANBIOSIS is coauthor of an article chosen to be highlighted on the ChemistryViews newsletter: “Organic Free Radicals as Circularly Polarized Luminescence Emitters”, published in Angewandte Chemie International Edition, and is about the intrinsic chiral emission of enantiometric organic free radicals.

The short news about the paper is entitled “Circulary Polarized Light from Organic Radicals” is available here. 

Circularly polarized luminescence (CPL) can occur when a luminescent compound has a chiral structure. Organometallic structures are leading in CPL activity. However, purely organic CPL emitters are promising alternatives in several applications where low toxicity is important
(i.e., bioimaging).

Jaume Veciana (Institut de Ciéncia de Materials de Barcelona (ICMAB), Spain), Araceli G. Campaña (University of Granada, Spain) and colleagues have found a new approach for the optimization of organic emitters with intrinsic chirality. In particular, tris(2,4,6-trichlorophenyl)methyl (TTM) and perchlorotriphenylmethyl (PTM) radicals, which both have a chiral propeller-like shape, were used. In addition to their chirality, these materials are magnetically active. They are also easy to modify in order to optimize their properties.

The team separated the two racemic compounds into their enantiomers using chiral stationary phase high-performance liquid chromatography (HPLC). The CPL spectra of the four resulting fractions (examples pictured) were recorded and the researchers found highly efficient chiral emission for both pairs of enantiomers. According to the researchers, this is the first time results about the intrinsic chiral emission from enantiomeric organic free radicals have been reported. The work might be a starting point for the development of improved chiral organic radical emitters.
