Article Abstract
Objective: To explore the predictive value of milk fat globule epidermal growth factor 8 (MFG-E8) in the occurrence of delayed cerebral ischemia (DCI) after an aneurysmal subarachnoid hemorrhage (aSAH).
Methods: We recruited 32 patients with aSAH as the case group and 24 patients with unruptured aneurysms as the control group. Serum MFG-E8 levels were measured by western blot and enzyme-linked immunosorbent assay. We analyzed the relationship between MFG-E8 levels and the risk of DCI.
Results: The levels of serum MFG-E8 in the case group (mean = 11160.9 pg/mL) were significantly higher than those in the control group (mean = 3081.0 pg/mL, < 0.001). MFG-E8 levels highly correlated with the World Federation of Neurosurgical Societies (WFNS) and modified Fisher scores ( = -0.691 and - 0.767, respectively, < 0.001). In addition, MFG-E8 levels in patients with DCI (5882.7 ± 3162.4 pg/mL) were notably higher than those in patients without DCI (15818.2 ± 3771.6 pg/mL, < 0.001). A receiver operating characteristic curve showed that the occurrence of DCI could effectively be predicted by MFG-E8 (area under the curve = 0.976, 95%CI = 0.850-1.000). Kaplan-Meier survival analysis showed a remarkable decrease in the incidence of DCI in case group individuals with high levels of MFG-E8 (≥11160.9 pg/mL, < 0.001).
Conclusion: MFG-E8 may be a useful predictive marker for DCI after an aSAH and could be a promising surrogate end point.

Background: Recent studies have revealed importance of human umbilical cord blood (HUCB)-derived exosomes (HUCB-Exo) in central nervous system diseases, but the role of HUCB-Exo in hypoxic-ischemic encephalopathy (HIE) remains unclear. This study aims to explore the mechanisms of HUCB-Exo in HIE.
Methods: HIE models were constructed in 7-day-old neonatal rats using classical Rice-Vannucci modeling, and SH-SY5Y cells were induced by oxygen-glucose deprivation/reperfusion (OGD/R) injury, followed by intervention with HUCB and HUBC-Exo, either non-transfected or transfected with si-NC/si-MFG-E8.

Background: Neutrophilic asthma, characterized by the relative accumulation of neutrophils in the airways, constitutes a distinct endotype of asthma resistant to corticosteroid and associated with severe and uncontrolled cases. Milk fat globule-EGF factor 8 (MFGE8) is a soluble glycoprotein functioning in phagocytosis, tissue repair, angiogenesis, and the regulation of neutrophil activity. However, the role of this glycoprotein in neutrophilic asthma has not been thoroughly investigated.

Coronary atherosclerosis narrows or occludes blood vessels, resulting in myocardial ischemia and hypoxia, which ultimately leads to coronary heart disease (CHD). The pathogenesis of CHD remains insufficiently elucidated. A widely accepted hypothesis is that various stimuli induce arterial intima injury, and atherosclerosis (AS)formation reflects the inflammatory-fibroproliferative response of the intima to such injury.

Extracellular vesicles (EVs) and secretory factors play crucial roles in intercellular communication, but the molecular mechanisms and dynamics governing their interplay in human pluripotent stem cells (hPSCs) are poorly understood. Here, we demonstrate that hPSC-secreted milk fat globule-EGF factor 8 (MFGE-8) is the principal corona protein at the periphery of EVs, playing an essential role in controlling hPSC stemness. MFGE-8 depletion reduced EV-mediated self-renewal and survival in hPSC cultures.

The current study aimed to clarify the roles of apolipoprotein A5 (ApoA5) and milk fat globule-epidermal growth factor 8 (Mfge8) in regulating myocardial lipid deposition and the regulatory relationship between them. The serum levels of ApoA5 and Mfge8 in obese and healthy people were compared, and the obesity mouse model induced by the high-fat diet (HFD) was established. In addition, primary cardiomyocytes were purified and identified from the hearts of suckling mice.
