Project Overview
The funded project aims to identify internalizing human antibodies that target pancreatic adenocarcinoma cells in situ (in their natural tissue microenvironment). Currently, there are very few human antibodies that target pancreatic tumors and even fewer detect early stage tumors. The study examines the following two key hypotheses: (1) pancreatic tumors, like other tumors, possess unique cell surface molecules that distinguish tumors from non-neoplastic tissues; and (2) a subset of these tumor cell surface molecules are internalizing, and thus can be exploited for tumor-targeted intracellular payload delivery.

The methods and strategies used in this study are based on precise procurement of staged tumor cells by laser capture microdissection to select internalizing human antibodies that target pancreatic cells in situ. These novel antibodies, which are human in sequence, can be used in the future to develop noninvasive imaging-based strategies for early pancreatic tumor detection and targeted therapeutics based on tumor-specific intracellular drug delivery.
