Our Technology

Antigen-presenting cells, such as dendritic cells, form an intimate contact with T cells to transfer antigenic signals (1), co-stimulatory signals (2) and paracrine cytokine signals (3). In this so-called immunological synapse, a variety of immunomodulating molecules aggregate to drive signaling that leads to activation and proliferation of immune effector cells such as T cells and NK cells. We developed unique semi-flexible polymers decorated with a variety of immunomodulating molecules to mimic natural antigen presenting cells. These ‘immunofilaments’ are designed to specifically activate and expand immune cells such as antigen specific cytotoxic T cells, CAR-T cells, or NK cells. Our immunofilaments not only effectively expand immune cells ex vivo, but can also drive expansion of immune cells in vivo, resulting in inhibition of tumor growth or metastasis.
