abstract = {Cancer types with lower mutational load and a
non-permissive tumor microenvironment are intrinsically
resistant to immune checkpoint blockade. While the
combination of cytostatic drugs and immunostimulatory
antibodies constitutes an attractive concept for overcoming
this refractoriness, suppression of immune cell function by
cytostatic drugs may limit therapeutic efficacy. Here we
show that targeted inhibition of mitogen-activated protein
kinase (MAPK) kinase (MEK) does not impair dendritic
cell-mediated T cell priming and activation. Accordingly,
combining MEK inhibitors (MEKi) with agonist antibodies
(Abs) targeting the immunostimulatory CD40 receptor results
in potent synergistic antitumor efficacy. Detailed analysis
of the mechanism of action of MEKi shows that this drug
exerts multiple pro-immunogenic effects, including the
suppression of M2-type macrophages, myeloid derived
suppressor cells and T-regulatory cells. The combination of
MEK inhibition with agonist anti-CD40 Ab is therefore a
promising therapeutic concept, especially for the treatment
of mutant Kras-driven tumors such as pancreatic ductal
adenocarcinoma.},
