Roger Colobran, researcher of the Immunology group at Vall d'Hebron Institute of Research (VHIR), is the author of 'https://www.youtube.com/watch?v=1Sd8haTluhE" Bombolles de colors', the song for research in primary immunodeficiencies that he plays with his rock band https://www.facebook.com/Boxets/home" Boxets. In less than 2 months, the videoclip has reached over 80,000 views! If it gets 100,000, the Obra Social 'la Caixa' will fund the second year of a predoctoral grant. The first year has already been funded by CSL Behring, after reaching 20,000 views. How did the initiative 'Bombolles de colors' begin?One day talking with Pere Soler (Head of the Infectious Diseases and Immunodeficiency of Paediatrics Unit and President of the Barcelona PID Foundation), he proposed that Boxets could do a song for the foundation and for all children who suffer from primary immunodeficiency (PID). We were inspired by a similar initiative we did a couple of years for the GAEM Foundation (Group of People Affected by Multiple Sclerosis), to whom we dedicated the song 'A prop'. What have you wanted to convey with the music and the lyrics of the song?Toying with the idea of Pere, I thought of a song we were preparing for Boxets' new album. It was a song still without lyrics and the kind of music was right to convey what we wanted. So I started to write the lyrics. For me it was both a pleasure and a responsibility to write the lyrics of this song because the subject is close to my heart: I work daily in the genetic diagnosis of PID. The lyrics of the song attempts to pay tribute to the children who suffer from PID and the parents and family caregivers. He also wants to send a message of optimism, given that, if we all join forces, we will be able to find ways to cure these diseases. On the other hand, the letter also aims to reinforce the idea that we can all do our bit to promote this cause. Tell me about Boxets. What would you highlight of the band?Boxets was formed in 1995: We were a group of friends who knew each other from school and the "esplai". We define ourselves as a rock band, but we have very different songs, from pop to hard rock. Throughout these years the formation has had some changes, but we really have never lost one of the treasures of the band, which is the friendship that brings us together. Beyond music, in Boxets we are like a family and I think it shows that when people get to know us and go to our concerts. So far we have published 4 albums: Quimera (2003), Follia (2008), Æ,ntropia (2012) y A prop (2016). Where does your passion for music come from? Did it come before your vocation for science?Initially from my father, who was a lover of classical music. I did music theory and played violin for some years. When I started Biology at the UAB (Autonomous University of Barcelona) I left the violin because it took too much time from my studies and it was not compatible with the degree. Then I started to play guitar self-taught, and we formed Boxets. Therefore music and science have always been an important part of my life. Science is my work and music is one of my passions. Initiatives such as 'Bombolles de colors' are very special to me because they allow me to join both things. You have worked in the VHIR since 2011. What are you specialized in?When I got here my research was focused on autoimmune diseases and specifically the role of the thymus and central tolerance in its development. We have made important contributions in this field, especially in Grave's Basedow disease, an autoimmune hyperthyroidism, and explain why http://en.vhir.org/portal1/news-detail.asp?contentid=171649&contenttypeid=295" individuals with Down syndrome have more susceptibility to autoimmune diseases. I am now more focused on the research associated with the PID, as it is more related to my work day to day: I am the Head of immunogenetics and therefore of the genetic diagnosis of children with PID to whom we dedicate the song 'Bombolles de colors'. What do you most like about your job?I like many things about my job: the constant scientific motivation, contact with all the professionals around me, the relationship with patients (in my case indirectly, because I usually only see their DNA... but I like to think I'm helping people), the unpredictability of science, the constant technological improvement... And the least?The lack of resources to do even more.
