Advances in cancer immunotherapy and resistance strategies

Overview

Academic research continues to advance immunotherapeutic approaches for aggressive cancers, such as HPV-driven head and neck squamous cell carcinoma (HNSCC) and triple-negative breast cancer (TNBC). Early efforts focused on using immune checkpoint inhibitors like ipilimumab and nivolumab to enhance T cell and natural killer (NK) cell functions.

Recent developments have expanded into sophisticated engineering and timing strategies to overcome resistance in solid tumors. At Stanford Medicine, researchers have successfully reprogrammed circulating NK cells into tissue-resident cells using specific levels of TGF-b signaling, allowing them to penetrate dense tumor microenvironments to attack melanoma and HNSCC.

At UC San Francisco, scientists have engineered a technique using induced pluripotent stem cells (iPSCs) to create dendritic cells. These cells are “dressed” with membrane bubbles from a patient’s own tumor to train T cells to identify and eradicate specific malignancies, including leukemia and ovarian cancer.

Further research at Cornell University emphasizes the importance of therapeutic timing; by using a compound to activate macrophages after targeted drugs induce resistance, researchers were able to eliminate more residual melanoma cells in mouse models. Additionally, the development of a new microfluidic platform called ATTACH provides an unbiased method for isolating antigen-specific T cells, leveraging tumor cells to enrich rare tumor-reactive T-cell populations by up to 10-fold.
