Lab Members

Amy Heimberger, M.D. 
Principal Investigator

Amy Heimberger, M.D., is a professor of Neurosurgery at MD Anderson Cancer Center and has been part of the faculty here since 2002. She has an extensive research program focused on immune therapeutic strategies for gliomapatients and studies tumor-mediated mechanisms of immune suppression. Her laboratory was pivotal in the development of a peptide (PEP-3-KLH/CDX-110) vaccine strategy that targets the epidermal growth factor receptor.  

In addition, Heimberger has clarified that the signal transducer and activator of the transcription3 (STAT3) pathway is a key molecular hub of gliomagenesis and tumor-mediated immune suppression. She also conducted the pre-clinical development of a novel small molecule inhibitor of STAT3, WP1066, which will be introduced into clinical trials in 2018 for melanoma patients with CNS metastasis and primary glioma patients. Furthermore, she showed that tumor-associated microglia/macrophages potentiate gliomagenesis via STAT3 and established that the glioma-associated cancer stem cells via the STAT3 pathway exert immune suppressive properties on both the adaptive and innate arms of the immune system. 

Heimberger is the only MD Anderson faculty member to be awarded the Presidential Early Career Award for Scientists and Engineers. She holds multiple NIH and foundation grants and is a project leader in both the Brain and Melanoma SPOREs. She is a leader of the Glioblastoma Moon Shot™. Heimberger has a clinical interest in awake mapping and resection of gliomas within eloquent cortex. She has been named by U.S. News and World Report as a Top Doc.

In July of 2002, Kong joined a team led by Nicholas Donato, Ph.D., and Moshe Talpaz, M.D., in the Bioimmunotherapy department at MD Anderson Cancer Center as a research scientist. In November of 2006, Kong joined Heimberger’s laboratory in the Neurosurgery department at MD Anderson and is currently a senior research scientist. She has over 10 years of experience working with STAT3 modulation with small molecule inhibitors, especially extensively studying the immune properties of WP1066 and related analogues both in vitro and in vivo.

Xiaoyang Ling, Ph.D.
Senior Research Scientist

Xiaoyang (John) Ling received his Ph.D. in molecular biology from China. He came to MD Anderson Cancer Center in 2000 and joined the Molecular Pathology and Leukemia department. There he studied the pSTAT3 singling pathway and its role in breast cancer oncogenesis. In 2012 he joined Heimberger’s lab to investigate the role of the immune system in glioblastoma. Ling is working to elucidate how immune cells function in the context of glioma in an elegant genetic CD8 knockout murine model. Using this model he is now dissecting the interactions among different immune population during GBM development.

Anantha Marisetty, Ph.D.
Postdoctoral Fellow

Anantha Marisetty received her bachelor’s degree in biotechnology at Nagarjuna University in India. She moved to the United States and obtained her master’s degree in biotechnology from the University of Massachusetts, Lowell, where she studied a novel Ca2+/ Calmodulin–dependent protein kinase cascade that regulates blood stem cell growth and development. Along with academic research, she was involved in industrial training at Acambis Inc., a subsidiary of Sanofi Pasteur, where she was involved in generating a peptide library and validation of humoral responses for a lead vaccine candidate.
