To single out BrB in MG as an important factor regulating erythrophagocytosis, and therefore hematoma cleanup through AhR activation, we demonstrated that while BrB enhances erythrophagocytosis in control MG, BrB does not affect erythrophagocytosis in MG harvested from MG-selective AhR knockout mice. This evidence concerns the gene AHR and myasthenia gravis.
