Our main goal is to study human immunology in adverse environments, and what happens when the immune system is compromised such as in cancers, microgravity and auto immune conditions. We are also involved in bone tissue engineering, and Dr.Sundaresan holds three patents for growing human bone outside of the body. Sundaresan also works with nutritional supplements in human cells and animals to study their ability to enhance the immune system and prevent neurodegeneration. A second role takes the PI, Dr.Sundaresan to the University of Texas Health Science Center at Houston Medical School once a week, where she is an Assistant Professor of Surgery involved with inflammation, toxic and immune response. A third role for this whirlwind scientist is Visiting Scientist at NASA’s Johnson Space Center in Houston. Our most recent experiment for NASA was aboard the successful SpaceX-3 and Spacex-8 launch in April 2014 and 2016. All our projects involve international collaboration. For example, our students and Post docs have the opportunity to work and network with many key collaborators in Denmark, Norway, Brazil, UK and Germany to name a few.
My laboratory focuses on Biomedical and STEM research in Immune suppression, inflammation, bone biology, tissue engineering, cardiovascular biomarkers and nutritional immunomodulation. The specific areas we investigate are upstream targets in lymphocyte signaling in inflammation and immune suppression, adaptive genetic response gene suites in altered adverse physiologies, hyper gravity and high altitude stress, lymphocyte locomotion and signal transduction, bone tissue engineering and resorption models and cancer /toxicity models. We also have ongoing projects in Nano-formulation, nanotechnology and mathematical radiation tissue modeling of heavy ion effects. We have worked over the past several years to determine genetic response suites in human lymphocytes under microgravity analog conditions (mimics ageing and inflammatory states). Many molecules related to T-cell activation and second messengers, located both in the cell membrane and cytoplasm have been shown to be significantly altered under microgravity analog conditions. The wealth of information documented by these studies is very helpful to identify and explore immune and physiological adaptation in immune dysfunction and inflammatory disease states. These are extrapolable to immune dysfunction due to ageing and increased inflammation on earth. Nutritional immunodulation of the immune system was of great interest to investigate since immune dysfunction was key in our scope of work. Signaling and lymphocyte function augmentation with nucleotides and biological response modifiers such as pre and probiotics is another primary focus in the lab. Our funding sources are NASA, NSF and Industrial partners.
