Mukesh K Sriwastva et al. [39] investigated the effect of mulberry bark-derived extracellular vesicles (MBELNs) against colitis and found that MBELNs prevent dextran sulphatesodium (DSS)-induced colitis in mice through the AhR/COPS8 pathway (Table 3). The gene discussed is AHR; the disease is colitis.
