Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Seton Hall University Dissertations and Theses (ETDs)
This dissertation reports the synthesis and biological applications of bifunctional trimeric peptides with B7H6-derived NKp30 binding motifs that serve to activate an immunocytotoxic response in natural killer cells and a GRP78-binding motif that can target tumors that express surface GRP78. In this manner the cancer-targeting immunostimulatory peptides are anticipated to directly bind and activate effector NK92-MI cells while also recognizing and binding to target A549 tumor cells to facilitate NK cell-dependent immunocytotoxicity of the targeted tumors. The NKp30 binding peptide motifs are derived from the tumor associated B7H6 antigen that is often downregulated or shed from the surface of tumors …

B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips
Seton Hall University Dissertations and Theses (ETDs)
Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …
