IL10 and combined immunodeficiency: A number of synthetic and natural small molecules (such as dexamethasone, Dexa, and vitamin D, VitD) have been reported to act as IL-10 inducers in vitro and in vivo (23–27), and investigations that explore different formulations, delivery systems, and route/dose/scheme of administration could be of particular interest to develop realistic forms of immune interventions for CID.
