Low doses favor the induction of Tregs and high doses favor the induction of anergy or deletion.[99] The efficacy of mucosal tolerance is currently undergoing testing in humans for the treatment of rheumatoid arthritis and multiple sclerosis, and no toxicities or autoimmune reactions have been found.[100],[101] However, we think that there are some shortcomings in the clinical transformation of mucosal tolerance in the treatment of brain diseases, for example, the individual mucosal absorption rate is uncertain; craniocerebral trauma is often associated with nose and facial injuries, often limiting the use of nasal mucosa antigen; severe TBI or stroke with stress ulcer requires fasting water and gastrointestinal decompression, limiting the use of oral immune tolerance.
High incidence of anergy in inflammatory bowel disease patients limits the usefulness of PPD screening before infliximab therapy.
(40) Anergized B cells are typically localized at the border between the T cell zone and follicle but not MZ (40) in the periphery, and excess CD40L fails to reverse anergy. (41) Thus, classical anergy does not appear to be induced in Sm/RNP-reactive B cells.

Although CTLA4Ig was initially envisioned to induce tolerance towards solid organ allografts by selective T cell costimulation blockade, which was intended to lead to anergy and tolerance, concerns arose whether it has a potentially detrimental impact on Tregs.
