Dartmouth College Ph.D Dissertations
The high immunogenicity of melanoma tumors makes these malignancies an attractive target for immunotherapeutic treatment, as evidenced by the success of ipilimumab and nivolumab. However, most immunotherapeutic approaches have had limited success, partly due to the suppression of innate and adaptive immune responses by tumor-associated macrophages (TAMs) in the tumor microenvironment (TME). TAM redirection may relieve immunosuppression in the TME, directly inhibiting melanoma growth and potentially enhancing the efficacy of additional targeted and immuno-therapies.
We have shown that synthetic oleanane triterpenoid CDDO-Me (or C-Me) enhances immune activation in the melanoma TME by reprogramming TAMs from immunosuppressive to immunostimulatory. CDDO-Me is …
