“Maintenance of the target peptide functional concentration in the gut and the maintenance of sufficient colonies are the most big two questions that a clinical physician interested in the most”, said Dr. CHENG. After explaining to him about our neuropeptide delivering system and the safety system we designed, he commented, “That is really a good approach!”. Dr. CHENG also mentioned that we should consider the peptide bacterial advantages over the normal flora. To maintain the steady dosage of peptide each time the bacteria produced, We need to find a way to stabilize the bacterial colony number and the consistency over time. He noted that each antibiotic usage or even diarrhea can change the colony status. How to increase the bacterial surviving ability should be our main concern.
