Harvard Neuroimmunologist Discusses Neuro-Immune Interactions and Their Impact on Inflammation
Harvard neuroimmunologist Dr. Isaac Chiu has been discussing the complex interactions between the nervous and immune systems, particularly focusing on how pain-sensing neurons, or nociceptors, detect bacterial toxins and influence immune responses. In a recent episode of a podcast, Dr. Chiu explained that these neurons release a peptide called CGRP, which can suppress the recruitment of neutrophils, a type of immune cell. This interaction plays a crucial role in regulating barrier defenses and allergy priming, as well as the resolution or failure of inflammation. The discussion also covered how inflammation can lower the threshold for pain, potentially leading to chronic pain issues, and how early skin exposure to allergens might promote food allergies.
