Post-Doctoral Fellow, Stanley S. Scott Cancer Center, LSUHSC, USA (2013-2018)


Dr. Sanchez-Pino’s born in Colombia where obtained her master's and doctoral degrees in Immunology of human tuberculosis. Her post-doctoral training was performed at Stanley S. Scott Cancer Center at LSUHSC- New Orleans under the mentorship of Dr. Augusto Ochoa in inflammation of viral infections and cancer. Since 2018, Dr. Sanchez was promoted to Assistant Professor. Currently, Dr. Sanchez is studying the relationship of chronic inflammatory immune cells with obesity-associated cancer.

Specifically, Dr. Sanchez-Pino aims to:

  1. Identify the major obesity-associated factors that promote myeloid-derived suppressor cells (MDSC) expansion and immunosuppressive function.
  2. Characterize the major molecular pathways associated with cellular metabolism in the obese and tumor microenvironments as critical regulators of the MDSC function.
  3. Elucidate the transcriptional regulatory network responsible for activating the immunosuppressive gene expression program of MDSC to uncover potential pharmacological targets.

Research Interests

Dr. Sanchez-Pino’s research training has focused on understanding mechanisms in chronic inflammatory diseases, such as tuberculosis, allergy, herpes keratitis, and more recently, in cancer, and obesity. She also has extensive experience processing clinical biospecimens gained while working as the director of a medical diagnostic laboratory in her native Colombia.
