Radioimmunotherapy strategies for pediatric tumors

“Our goal is to develop effective therapeutic strategies against childhood tumors without compromising patients' quality of life.”

There is increasing evidence on the interaction between the nervous system and the immune system in different pathologies including cancer.

Therefore, our group, integrated in the Cancer Center Clínica Universidad de Navarra,  studies the immune component within the tumor as well as in response to radiotherapy, a key element in the treatment of childhood brain tumors, for the development of effective therapeutic strategies.

At the same time, we know that neuroinflammation is behind the causes that generate cognitive impairment in patients with early brain tumors. Therefore, another pillar of our research focuses on the development of neuroprotective therapies that ensure the quality of life of patients once the disease is overcome.

Objectives of the Radio-immunotherapy strategies for pediatric tumors. Research Group

Immunomodulation of the tumor microenvironment as a treatment for diffuse midline glioma in the spinal cord.

Development of radio and immunotherapy combinations for pediatric brain tumors.

Study of the role of neuroinflammation in cognitive impairment after brain radiotherapy and development of mitigation strategies using different models of childhood brain tumors.

The immune microenvironment of tumors and neuroinflammation

Through the study of patient samples and animal models we characterize with techniques such as single cell transcriptomics or spatial transcriptomics the immune microenvironment of tumors as well as the neuroinflammation generated by radiotherapy to find possible targets and develop therapeutic strategies.

Lines of research

PI: Sara Labiano and Jaime Gállego

Diffuse midline glioma (DMG) is a pediatric tumor with a very poor prognosis and for which there are currently no effective treatments. Although the vast majority of cases occur in the brainstem and thalamus, in this project we have focused on the study of those DGM located in the spinal cord, for which until now there were no orthotopic and immunocompetent pre-clinical models that would allow us to rigorously study their microenvironment as well as specific translational therapies for this location. 

Objectives:

Characterization of the immune microenvironment of spinal cord MGD and development of a spinal cord MGD model for the translational study of immunotherapies against this disease.

PI: Sara Labiano

For pediatric patients with brain tumors, radiotherapy is one of the mainstays of treatment. However, in those patients with MGD, radiotherapy barely manages to extend survival. In this project we study new immunotherapy strategies to enhance the effects of radiotherapy focusing on myeloid cells, which are also the most frequent immune population in MGD, as targets to initiate and coordinate an effective and long-lasting antitumor response. 

Objectives:

Study of different radio-immunotherapies directed against the myeloid tumor component, as well as their mechanism of action.

PI: Sara Labiano

Although radiotherapy is a key treatment for brain tumors, more than half of the patients end up suffering serious cognitive sequelae from this therapy in the medium and long term. Therefore, in this line of work we focus on the development of neuroprotective strategies to prevent or alleviate the cognitive damage associated with brain irradiation and thus improve the quality of life of patients, especially pediatric patients, who have overcome the disease. 

Objectives:

Characterization of the inflammatory mechanisms underlying cognitive deficit after brain radiotherapy and development of neuroprotective strategies based on immunotherapy.

Tumors of the nervous system

Tumors of the nervous system are the leading cause of death by disease in pediatric patients.

For certain tumors such as Diffuse Midline Glioma there is currently no effective treatment.

In other tumors with better prognosis such as Medulloblastoma or Low Grade Gliomas, it is the treatment that ends up generating both physical and mental sequelae that end up impacting the quality of life of patients and their families.
