abstract = {Eradication of cancer cells by the immune system requires
extravasation, infiltration and progression of immune cells
through the tumor extracellular matrix (ECM). These are also
critical determinants for successful adoptive cell
immunotherapy of solid tumors. Together with structural
proteins, such as collagens and fibronectin, heparan sulfate
(HS) proteoglycans are major components of the ECM.
Heparanase 1 (HPSE) is the only enzyme known to have
endoglycosidase activity that degrades HS. HPSE is expressed
at high levels in almost all hematopoietic cells, which
suggests that it plays a relevant role in immune cell
migration through solid tissues. Besides, tumor cells
express also HPSE as a way to facilitate tumor cell
resettlement and metastasis. Therefore, an increase in HPSE
in the tumor ECM would be detrimental. Here, we analyzed the
effects of constitutive expression of an active,
membrane-bound HPSE on the ability of human natural killer
(NK) cells to infiltrate tumors and eliminate tumor cells.
We demonstrate that NK cells expressing a chimeric active
form of HPSE on the cell surface as an integral membrane
protein, display significantly enhanced infiltration
capability into spheroids of various cancer cell lines, as
well as into xenograft tumors in immunodeficient mice. As a
result, tumor growth was significantly suppressed without
causing noticeable side effects. Altogether, our results
suggest that a constitutively expressed active HSPE on the
surface of immune effector cells enhances their capability
to access and eliminate tumor cells. This strategy opens new
possibilities for improving adoptive immune treatments using
NK cells.},
