Bile acids (BAs) are originally known as detergents essential for the digestion and absorption of lipids. In recent years, extensive research has unveiled new functions of BAs as gut hormones that modulate physiological and pathological processes, including glucose and lipid metabolism, energy expenditure, inflammation, tumorigenesis, cardiovascular disease, and even the central nervous system in addition to cholesterol homeostasis, enterohepatic protection and liver regeneration. BAs are closely linked with gut microbiota which might explain some of their crucial roles in organs.

Article Synopsis
  • - The study focuses on a human monoclonal antibody, CS-D7, that targets the iron-regulated surface determinant B (IsdB) of **Staphylococcus aureus** and shows potential for opsonophagocytic killing and protection in a murine sepsis model.
  • - Despite the lack of heme binding activity and reduced opsonization in a mutated version of CS-D7 (CS-D7·N297A), both forms provided similar protective effects in mice, indicating that the antibody's Fc region isn’t crucial for its protective capabilities.
  • - The mechanisms of CS-D7's protection appear to involve complement, phagocytes, and lymphocytes, with increased clearance of the bacteria and IF
