Chronic diseases, including cardiovascular and neurodegenerative diseases and cancer, are significant global health challenges. Oxidative stress, characterized by an imbalance between reactive oxygen species (ROS) production and antioxidant defenses, is a critical factor in the progression of these pathologies. Lactoferrin (Lf), a multifunctional iron-binding glycoprotein, has emerged as a promising therapeutic agent due to its potent antioxidant, anti-inflammatory, and iron-regulating properties.

Studying iron transfer across trophoblast monolayers is crucial given the significance of iron in maintaining a healthy pregnancy and supporting fetal growth and development. To get insights into the complex mechanism of transplacental iron transfer, we developed a standardized Transwell®-based monolayer model using BeWo (clone b30) cells. Our proposed method is divided into two parts: 1.

: The key components of the blood-brain barrier (BBB) are endothelial cells, pericytes, astrocytes, and the capillary basement membrane. The BBB serves as the main barrier for drug delivery to the brain and is the most restrictive endothelial barrier in the body. Nearly all large therapeutic molecules and over 90% of small-molecule drugs cannot cross the BBB.

Background: Transferrin receptor (TFRC) uptakes iron-loaded transferrin (TF) to acquire iron and regulates tumor development. Nonetheless, the clinical values and the precise functions of TF-TFRC axis in the development of oral squamous cell carcinoma (OSCC) were still undiscovered, especially the impacts of their regional heterogeneous expression.
Methods: Immunohistochemistry (IHC) was used to analyze the expression of TFRC in 106 OSCC patients.
A shorter linker in the bispecific antibody RmAb158-scFv8D3 improves TfR-mediated blood-brain barrier transcytosis in vitro.

Transferrin Receptor (TfR)-mediated transcytosis across the blood-brain barrier (BBB) enables the uptake of bispecific therapeutic antibodies into the brain. At therapeutically relevant concentrations, bivalent binding to TfR appears to reduce the transcytosis efficiency by receptor crosslinking. In this study, we aimed to improve BBB transcytosis of symmetric antibodies through minimizing their ability to cause TfR crosslinking.
