Carbidopa is a drug that blocks conversion of levodopa to dopamine outside of
central nervous system (CNS) and thus inhibits unwanted side effects of levodopa
on organs located outside of CNS during management of Parkinson's Disease (PD).
PD is associated with increased expression of inflammatory genes in peripheral
and central nervous system (CNS), infiltration of immune cells into brain, and
increased numbers of activated/memory T cells. Animal models of PD have shown a
critical role of T cells in inducing pathology in CNS. However, the effect of
carbidopa on T cell responses in vivo is unknown. In this report, we show that
carbidopa strongly inhibited T cell activation in vitro and in vivo. Accordingly,
carbidopa mitigated myelin oligodendrocyte glycoprotein peptide fragment 35-55
(MOG-35-55) induced experimental autoimmune encephalitis (EAE) and collagen
induced arthritis in animal models. The data presented here suggest that in
addition to blocking peripheral conversion of levodopa, carbidopa may inhibit T
cell responses in PD individuals and implicate a potential therapeutic use of
carbidopa in suppression of T cell mediated pathologies.
