Purpose: To observe the effect of soya yoghurt (Soyghurt), which is high in flavonoid substance, on the expression of preeclampsia biomarkers (sFLT-1 and PLGF) on preeclampsia serum-induced trophoblast primary cell culture isolated from placental tissue.

Methods: The trophoblast primary culture was induced by preeclampsia serum (10%). The Soyghurt treatment was performed with 2.

Article Synopsis
  • Aquaporin-4 (AQP4) is a key water channel in the brain that helps manage water movement and is important in various diseases, but how it's regulated is still unclear.
  • Researchers studied AQP4 in mouse brain slices and found that it is concentrated in a detergent-resistant membrane fraction, indicating it has a unique location and behavior compared to other proteins.
  • Under ischemic conditions (simulated by oxygen-glucose deprivation), they observed a decrease in AQP4 levels in this resistant fraction before the overall AQP4 levels dropped, indicating different regulatory mechanisms depending on the state of the brain.

Neuromyelitis optica (NMO), an autoimmune disease of the central nervous system, is characterized by an autoantibody called NMO-IgG that recognizes the extracellular domains (ECDs) of aquaporin-4 (AQP4). In this study, monoclonal antibodies (mAbs) against the ECDs of mouse AQP4 were established by a baculovirus display method. Two types of mAb were obtained: one (E5415A) recognized both M1 and M23 isoforms, and the other (E5415B) almost exclusively recognized the square-array-formable M23 isoform.

Aquaporin-4 (AQP4), the most abundant water channel in the brain, plays a central role in water homeostasis, neuronal activity, and migration of astrocytes in the central nervous system. Recent studies have demonstrated that AQP4 is a target of an autoantibody specifically detected in an autoimmune neurologic disease called neuromyelitis optica. Here we have generated a monoclonal antibody (MAb) against the C-terminal region of AQP4 using a baculovirus expressing mouse AQP4 as an immunogen.
