Reprogramming monocyte-derived macrophages through caspase inhibition.

ABSTRACT: Macrophages are widely distributed innate immune cells that play an indispensable role in a variety of physiologic and pathologic processes, including organ development, host defense, acute and chronic inflammation, solid and hematopoietic cancers. Beyond their inextricable role as conveyors of programmed cell death, we have previously highlighted that caspases exert non-apoptotic functions, especially during the differentiation of monocyte-derived cells in response to CSF-1. Here, we found that non-canonic cleavages of caspases, reflecting their activation, are maintained during IL-4-induced monocyte-derived macrophages polarization. Moreover, Emricasan, a pan-caspase inhibitor that demonstrated promising preclinical activity in various diseases and safely entered clinical testing for the
