nanoparticles for drug delivery

Women in the fight against breast cancer: Ibane Ibasolo

The International Day of Women and Girls in Science on February 11 honor women’s significant achievements in science and place a much-needed focus on girls entering Science, Technology, Engineering, and Mathematics (STEM) careers.

We want to take this day to congratulate all the women scientists, especially our scientists at NANBIOSIS ICTS. Some of them take an active role in the dissemination of research results and reseach contribution to the society, as Dr. Ibane Abasolo who last week participated in different events to explain her team work in the figth against breast cancer.

Ibane Abasolo is the Scientific Coordinator of NANBIOSIS U20 and also the leader of the Drug Delivery & Targeting group of the CIBER-BBN at the Vall d’Hebron Research Institute (VHIR) which coordinates the unit 20 of NANBIOSIS, a team composed mainly by women.

The group cooworks to improve cancer treatment through the development of nanoparticles specially directed towards breast cancer stem cells. These cells are the ones that, despite dividing slowly, give rise to the differentiation of the rest of the tumor cells and are also the most resistant to conventional antitumor treatments.

That is why the group seeks to attack these cells in three ways:

i) selected drugs that induce the differentiation of tumor stem cells into more differentiated cells (and easier to treat),

2) using mechanisms to evade the efflux pumps of drugs and

3) targeting the nanoparticles specifically towards tumor stem cells by using targeting agents (ie antibodies) against antigens on the surface of tumor stem cells.

Dr. Abasolo has illustrated these three approaches by citing papers published in her group during 2021, in which the ICTS Nanbiosis U20 has also directly participated:

Successful meeting on Biomedicine between the University of Turin and NANBIOSIS/CIBER-BBN

Last November 8th, 2016 took place in Barcelona, in the Residence of Researchers of CSIC, a meeting of Italian-Spanish scientists, the first Investigators B2B Forum organized by NANBIOSIS. The meeting reached its objective of bringing together the interests of researchers from University of Turin and NANBIOSIS/CIBER-BBN on biomaterials and nanomedicine.

Nine groups from L’Università di Torino together with sixteen groups from CIBER-BBN and CCMIJU (partners of NANBIOSIS), got together to explain through short presentations of ten minutes, those lines of their work aimed at finding synergies and potential collaborations. In the afternoon, the groups had the opportunity to discuss in more detail, during bilateral interviews coordinated by NANBIOSIS, those aspects that had attracted their attention, as well as, in some cases, to draw potential collaborations.

Topics as preclinical validation of nanomedicines, animal models, custom peptide synthesis, carbon nanotubes and graphene for biomedicine, micronanotecnology, drug microencapsulation, nanoestuctured liquid characterizacion, surface microanalysis of biomaterials, pharmacodynamics, preclinical in vivo MRI and MRSI, tissues and biomaterials MRI, nanoparticles for drug delivery, nanoestructuring soft materials or customized molecular materials for biomedical applications, among others, were discussed during the 75 B2B meetings celebrated.

All the attendees expressed, at the end of the event, the usefulness of the meetings with this format and their satisfaction at having found possibilities of collaboration thanks to their participation in this forum and encouraged NANBIOSIS to continue this initiative.”
