A study published in the January 15 edition of the journal Glia examined “proinflammatory mediators” ? chemicals which can play an important role in inflammatory processes that cause brain damage. The study found that cannabinoids were effective in reducing the release of these harmful substances by microglia, a special type of brain cell. (Glia and microglia are brain cells which provide mechanical and physical support for neurons.)
This effect was not mediated by either one of the two known cannabinoid receptor types (CB1 and CB2). Therefore, this suggests the existence of an additional, unidentified cannabinoid receptor type in these brain cells.
