OUR FOUNDER 

Dr. Anahid Jewett’s work is concentrated on the mechanisms of inactivation and cell death of Natural Killer cells. These cells play crucial effector functions in the host defense against viral and bacterial infections and malignant transformation. Dr. Jewett has shown that cytotoxic function of NK cells is significantly suppressed in the tumor microenvironment by a number of distinct effectors. She has previously demonstrated the role of NK cells in specific elimination of stem cells and not their differentiated counterparts. 


Indeed, she was the first to coin the term split anergy for the function of NK cells. She has also discovered that there is a stage wise susceptibility to NK cell mediated cytotoxicity in many tumors in which case the poorly differentiated tumors were lysed much more than their moderately differentiated tumors. The well differentiated tumors were lysed the least when compared to there is a stage wise susceptibility to NK cell mediated cytotoxicity in many tumors in which case the poorly differentiated tumors were lysed much more than their moderately differentiated tumors. The well differentiated tumors were lysed the least when compared to either the moderately differentiated tumors or to poorly differentiated tumors. 


She have also reported that inhibition of differentiation or reversion of cells to a less-differentiated stage by blocking key genes significantly augmented NK cell cytotoxicity against both transformed and healthy cells. Therefore, she has proposed that the two stages of NK cell maturation namely CD16+CD56dimCD69- NK cells were important for the selection of stem cells whereas the CD16dim/-CD56dim/+CD69+NK cells were important for differentiation and eventual regeneration of the tissues and the resolution of inflammation, thus serving as regulatory NK cells (NKreg). 


The concept of split anergy in NK cells and generation of NKreg and its contribution to cell differentiation, tissue repair and regeneration and in tumor resistance remains important areas of studies in her laboratory. In addition to studies on NK cells she also works on two other projects: 1- the mechanism of toxicity and allergic responses induced by HEMA and TEGDMA and 2-bacterial mediated regulation of immune function. Briefly, she has determined the detailed mechanisms of uptake and clearance of HEMA and TEGDMA, two chemical resins, which are in widespread use as biomaterials in dentistry. 


Finally, she has characterized an oral bacterium, which induces significant levels of lymphocyte apoptosis. Moreover, she is now studying the role of probiotics in conditioning of NK cells to support differentiation, tissue repair and regeneration and resolution of inflammation.

THE TEAM

Dr. Anna Kozlowska is an Assistant Professor from Poznan University of Medical Sciences in Poland. After receiving her MS degree in biotechnology and PhD in medical biology from PUMS, she gained post-doctoral training at City of Hope Medical Center (Duarte, CA) where she conducted preclinical tests of new cancer immunotherapeutics. She joined Dr. Jewett’s laboratory in order to continue her translational research on immune aspect of human malignancies and immunotherapy of cancer.  As a result of collaboration between PUMS and UCLA, she leads a collaborative project on a novel therapeutic strategy combining whole cell cancer vaccine and adoptive transfer of expanded NK cells in advanced melanoma patients. Since preclinical data obtained from humanized mice has shown great promise, the project will be heading towards clinical trials in human and eventual therapy of melanoma. Her personal objective is to bring innovation and entrepreneurship to Poland.


Dr. Kawal Mann is pursuing her PhD degree in Dr. Jewett’s laboratory after obtaining clinical degree in Dentistry and a Master’s degree at UCLA. Her research focuses on optimizing the expansion of super-charged Natural Killer cells for use in clinical trials in cancer patients. In addition, she is studying the role of immunosuppression in osteonecrosis of the Jaw (ONJ) as well as the effect of high fat diet in initiation and progression of pancreatic cancers. She uses humanized mice as well as gene knock out mice for her studies of Natural Killer cells.

Paytsar Topchyan is a graduate student conducting translational immunotherapy research in Dr. Jewett’s cancer immunology laboratory at UCLA. Her current research focuses on the role of probiotic bacteria and adoptive Natural Killer cell transfer in the humanized mouse model, as immunotherapy against Oral Squamous Carcinoma Stem Cells (OSCSCs). She also collaborates with fellow lab members in studying NK immunotherapy in the pancreatic cancer model as well as the melanoma model. In the future, Paytsar plans to pursue a career as a physician scientist, hoping to both contribute to the discovery of new scientific knowledge within the scope of tumor immunology, and its use in the clinical setting. Her goal is to serve patients in two ways simultaneously: by advancing medical knowledge on a large scale as a researcher and also on a personal level by directly working with patients to improve their quality of life.

Christian Mendoza is a second year graduate student, working on novel immunotherapeutics against cancer in Dr. Jewett’s lab.  His work focuses on optimizing the expansion and functionality of NK cells to use in preclinical research in humanized mice.  He uses newly patented technology to expand large numbers of Natural Killer cells with potent function to lyse stem-like cancer cells which seed the cancer. Chris hopes to continue his research as he pursues a career in clinical dentistry.
