Background: Acute respiratory distress syndrome (ARDS), a life-threatening condition during critical illness, is a common complication of COVID-19. It can originate from various disease etiologies, including severe infections, major injury, or inhalation of irritants. ARDS poses substantial clinical challenges due to a lack of etiology-specific therapies, multisystem involvement, and heterogeneous, poor patient outcomes.

However, the CAP mechanism attenuating distal tissue inflammation, inducing a low level of systemic inflammation, is lesser known. In this study, we hypothesized that CAP regulates monocyte accessibility by influencing their adhesion to endothelial cells.

Receptor-interacting protein kinase 3 (RIPK3) is a key mediator of this pathway. Accumulating evidence supports a critical role of RIPK3 and the necroptosis pathway in various human diseases.

However, the detailed role of sympathetic signaling in inflammatory diseases is still unclear because it varies according to the disease situation and responsible cell types. This study focused on identifying the functions of sympathetic signaling in macrophages in LPS-induced sepsis and renal ischemia-reperfusion injury (IRI).

However, there have been no reports that have demonstrated the effectiveness of VNS after injury. We investigated the renoprotective effect of VNS in a cisplatin-induced nephropathy model.

We retrospectively evaluated the decrease in autoantibody titer and pemphigus disease area index following double-filtration plasmapheresis in five patients with moderate to severe pemphigus, who were physically and/or serologically unresponsive to 1.0 mg/kg per day of prednisolone and other supportive drugs and ointments.
