Looking for the font in this Frontiers of Immunology figure from the lab of Jose Antonio Perez-Simon in Sevilla in 2020

Provided is screenshot of two words in the figure and a link to the article. The source could either be the researcher Jose Antonio Perez-Simon (most likely) or the frontiers of immunology publication company based in Switzerland. It comes from a figure in a recent science publication (2020) but the figure could have been created at most 5 years before that. The font or a free alternative would be greatly appreciated!   https://www.researchgate.net/publication/341937542_Overcoming_Chimeric_Antigen_Receptor_CAR_Modified_T-Cell_Therapy_Limitations_in_Multiple_Myeloma
