摘要
Given that apoptosis is the dominant modality of homeostatic cell turnover,efficient clearance of apoptotic cells(ACs),which is a process known as efferocytosis,is critical for immune homeostasis.The phagocytic engulfment of ACs occurs through an immunologically silent process to prevent an immune response to self-antigens.Correspondingly,defects in the removal of ACs have been proposed to underlie the pathogenesis of systemic lupus erythematosus(SLE).1,2 However,pathways that regulate phagocytes for efficient immune-silent AC uptake remain to be fully elucidated.Dicer is best known for its role as a riboendonuclease in the biogenesis of microRNAs.3 While recent studies have determined a link between microRNAs and AC clearance,the interplay between Dicer and efferocytosis remains unknown.
