My current research interests include: (1) improving\u00a0<\/span>ex vivo<\/i>\u00a0<\/span>methodologies to help determine the functional interchanges between cell subsets\u00a0<\/span>in vivo<\/i>\u00a0<\/span>that dictate an fate of a diseased site (e.g. tumor) and its impact on surrounding areas (2) investigating the differentiation potential and lineage relationships of iNKT cell subsets, and (3) elucidating the steps of immune cell exhaustion, the diversity of an exhausted, antigen-specific immune repertoire, and its role in the progression of chronic diseases.<\/p>\n

(1) Within a given microenvironment, complex functional exchanges occur between cells.\u00a0 Attempts to define the roles of cellular subsets within a site, such as a solid tumor, using surface markers and\/or secretion of a small number of functions (as current methods allow) are not reflective of\u00a0<\/span>in vivo<\/i>\u00a0<\/span>biology. Elucidating the composite functional activity of individual cells from within disease sites, such as solid tumors and granulomas, will provide new insight into the mechanisms and distinct cellular subsets that impact both its progression and response to therapeutic interventions.<\/p>\n

(2) iNKT cells are a unique T cell subset that are believed to bridge the innate and adaptive arms of an immune response.\u00a0 They have been implicated as key factors in the prevention of some autoimmune diseases, as well as potent effector cells in the containment of viral and bacterial infections, including HIV.\u00a0 Conversely, many studies report that iNKT cells have deleterious effects on the host during autoimmune and infectious diseases.\u00a0 This seemingly conflicting data is likely due to nuances of the differentiation and selective exertion of effector functions by subsets of this cell type that remain poorly understood.\u00a0 Further investigation of the lineage relationships and functional differences between the major iNKT subsets could lead to a deeper understanding the diverse impact of the iNKT cell compartment on disease progression.<\/p>\n

(3) During many chronic diseases, antigen-specific CD8+ T cells exhibit low functional activity, express inhibitory receptors, and have little\/no proliferative capacity; this reversible state is identified as \u2018exhaustion\u2019.\u00a0 Clinical trials of therapies that block inhibitory receptor signaling on T cells in cancer patients have been ongoing for several years. \u00a0Recently, trials targeting the PD-1\/PD-1L pathway in many advanced malignancies (including melanoma, non-small cell lung cancer, and renal carcinoma) have reported groundbreaking results, with some patients exhibiting 100% tumor reduction. These are arguably the most promising cancer immunotherapy trial results to date.\u00a0 Elucidation of both the complexity of the exhaustion process and the diversity of the exhausted immune cell repertoire in chronic diseases such as cancer will lead to more targeted, effective therapeutics.<\/p>\n","protected":false},"excerpt":{"rendered":"
