Targeting macrophage circadian rhythms with microcurrent stimulation to activate cancer immunity through phagocytic defense.

Macrophage phagocytosis plays a role in cancer immunotherapy. The phagocytic activity of macrophages, regulated by circadian clock genes, shows time-dependent variation. Intervening in the circadian clock machinery of macrophages is a potentially novel approach to cancer immunotherapy; however, data on this approach are scarce.

Monocyte/Macrophage-Specific Loss of ARNTL Suppresses Chronic Kidney Disease-Associated Cardiac Impairment.

Defects in Aryl hydrocarbon receptor nuclear translocator-like 1 (ARNTL), a central component of the circadian clock mechanism, may promote or inhibit the induction of inflammation by monocytes/macrophages, with varying effects on different diseases. However, ARNTL's role in monocytes/macrophages under chronic kidney disease (CKD), which presents with systemic inflammation, is unclear. Here, we report that the expression of in monocytes promoted CKD-induced cardiac damage.

Time-Dependent Differences in Vancomycin Sensitivity of Macrophages Underlie Vancomycin-Induced Acute Kidney Injury.

Although vancomycin (VCM)-frequently used to treat drug-resistant bacterial infections-often induces acute kidney injury (AKI), discontinuation of the drug is the only effective treatment; therefore, analysis of effective avoidance methods is urgently needed. Here, we report the differences in the induction of AKI by VCM in 1/2-nephrectomized mice depending on the time of administration. Despite the lack of difference in the accumulation of VCM in the kidney between the light (ZT2) and dark (ZT14) phases, the expression of AKI markers due to VCM was observed only in the ZT2 treatment.
