abstract = {Glioblastoma, the most common and aggressive primary brain
tumor type, is considered an immunologically 'cold' tumor
with sparse infiltration by adaptive immune cells.
Immunosuppressive tumor-associated myeloid cells are drivers
of tumor progression. Therefore, targeting and reprogramming
intratumoral myeloid cells is an appealing therapeutic
strategy. Here, we investigate a β-cyclodextrin
nanoparticle (CDNP) formulation encapsulating the Toll-like
receptor 7 and 8 (TLR7/8) agonist R848 (CDNP-R848) to
reprogram myeloid cells in the glioma microenvironment. We
show that intravenous monotherapy with CDNP-R848 induces
regression of established syngeneic experimental glioma,
resulting in increased survival rates compared with unloaded
CDNP controls. Mechanistically, CDNP-R848 treatment reshapes
the immunosuppressive tumor microenvironment and
orchestrates tumor clearing by pro-inflammatory
tumor-associated myeloid cells, independently of T cells and
NK cells. Using serial magnetic resonance imaging, we
identify a radiomic signature in response to CDNP-R848
treatment and ultrasmall superparamagnetic iron oxide
(USPIO) imaging reveals that immunosuppressive macrophage
recruitment is reduced by CDNP-R848. In conclusion,
CDNP-R848 induces tumor regression in experimental glioma by
targeting blood-borne macrophages without requiring adaptive
immunity.},
