Description:
Background: Clozapine (CLZ) and risperidone (RIS) are drugs that have the ability to disrupt
mitochondrial function. Also, these drugs increase the level of free radicals. Mitochondrial
dysfunction plays a role in the etiology of various diseases. Replacement and treatment of
defective mitochondria with healthy mitochondria have been considered. Mitochondrial
therapy (mitotherapy) or exogenous mitochondria transplantation is a method that can be used
to replace dysfunctional mitochondria with healthy mitochondria. This method can help in the
treatment of diseases related to mitochondria.
Methods: In this study, we investigated the transplantation effect of isolated lymphocyte
mitochondria on the toxicity induced by CLZ and RIS on human blood lymphocytes.
Lymphocytes were isolated using the Ficoll standard method. Mitochondria of human
lymphocytes were used for mitotherapy. This study was conducted in 6 groups. After treatment,
the level of reactive oxygen species (ROS), mitochondrial membrane potential (MMP), reduced
glutathione (GSH) content, oxidized glutathione (GSSG) content, and adenosine triphosphate
(ATP) content were evaluated.
Results: Our data showed that CLZ (70 µm) and RIS (24 nM) caused cytotoxicity on human
blood lymphocytes which are associated with ROS generation, collapse in MMP, decrease in GSH
content, increase in GSSG content and change in ATP content. Mitochondria transplantation
results showed that adding mitochondria of lymphocytes could protect the lymphocytes against
the toxicity effects caused by CLZ and RIS. Furthermore, the results showed that pre-incubation
with cytochalasin D considerably reserved the protective effects of mitotherapy in the human
lymphocytes.
Conclusion: We proposed that mitochondria transplantation or mitotherapy-affected blood
lymphocytes with exogenous mitochondria could be used to treat CLZ and RIS-induced toxicity
