Benjamín Pineda is a Chemical Bacteriologist and Parasitologist from the National School of Biological Sciences, IPN (2000). He has a master's degree and a doctorate with a specialty in Immunology. He completed his postdoctoral stay at the Brain Tumor Center of the University of Chicago in 2009. Currently, he is a researcher in Medical Sciences “E” at the National Institute of Neurology and Neurosurgery and is a member of the National System of Researchers level 3. His research work on the modulation of the antitumor immune response and the microenvironment of brain tumors has led him to propose various molecules with antitumor potential or modulation of the antitumor immune response, among them are those extracted from various vegetables, such as extract of hops, garlic, and Calophyllum Brasiliense. At the same time, he has carried out various studies on the impact of tryptophan catabolism on the modulation of the microenvironment of tumors of the central nervous system and how its metabolites impact the antitumor immune response. He has also designed and tested carbon nanostructures for the elimination of tumor cells in situ or as nanocarriers for various chemotherapeutics. His performance has allowed him to develop and patent an IgY immunotoxin against CD133 + carcinogenic stem cells, as well as developing an antitumor vaccine based on microvesicles from irradiated tumor cells for the treatment of various neoplasms.
