Over the past decade, intravenous immune globulin therapy (IVIG) has gained widespread use for a variety of clinical disorders. IVIG treatment is associated with a number of complications, including acute renal failure (ARF). Although the cause of IVIG-associated ARF is unknown, it may be related to the stabilizing agent used in the IVIG preparation. The development and resolution of ARF is typically rapid, but is some cases recovery may be delayed and require renal replacement therapy. In such patients, recurrence of ARF may be avoided by selection of a preparation with a different stabilizing agent. Two cases of IVIG-induced ARF are described, and all reported cases are analyzed to assess the probable mechanism of renal injury.

Intravenously transplanted mesenchymal stromal cells (MSCs) have been shown to interact with endothelial cells and to migrate to tissues. However, intracellular signals regulating MSC migration are still incompletely understood. Here, we analyzed the role of Rap1 GTPase in the migration of human bone marrow-derived MSCs in vitro and in short-term homing in mice in vivo.

Background: Sepsis is a severe condition causing organ failure due to an abnormal immune reaction to infection, characterized by ongoing excessive inflammation and immune system issues. Osteopontin (OPN) is secreted by various cells and plays a crucial role in inflammatory responses and immune regulation. Nonetheless, the precise function of OPN in sepsis remains to be elucidated.

Manganese ions (Mn) are an immune activator that enhances the activation of both cGAS and STING proteins. The STING signaling activation and subsequential immune responses are predominantly associated with endoplasmic reticulum (ER). Therefore, ER targeting of Mn in the subcellular compartments would promote the activation of STING signaling pathways.

Gastrointestinal immunity and antioxidant defenses may be bolstered in young animals through prenatal immune system stimulation (PIS), but this is largely uninvestigated in swine. This study tested the hypothesis that PIS could regulate offspring's gastrointestinal immune response and oxidative stress profile. To this end, a PIS model was utilized in sows, delivering low-dose LPS during the final third of gestation to target the developing immune system.
