Immunohistochemical Analysis of Mitochondrial Ferritin in the Midbrain of Patients with Parkinson's Disease.
Mitochondrial ferritin (FtMt) is an endogenous iron-storage protein localized in the mitochondria. FtMt is mainly observed in restricted tissues, such as those in the testis, islets of Langerhans, and brain. Further, it may protect cells from oxidative stress in neurodegenerative diseases, including Alzheimer's disease and progressive supranuclear palsy. However, the role of FtMt in Parkinson's disease (PD) remains unclear. Therefore, the current study investigated the localization and expression level of FtMt in the midbrain of patients with PD and healthy controls using immunohistochemical techniques. FtMt immunoreactivity was mainly detected in dopaminergic neurons in the substantia nigra pars compacta (SNc) in both healthy controls and patients with PD. In addition, FtMt-positive particles were observed outside the dopaminergic neurons in patients with PD. Based on a quantitative comparison, patients with PD had a significantly upregulated FtMt immunoreactivity in dopaminergic neurons than healthy controls. Our result might be helpful in future studies on the role of FtMt in PD.
期刊介绍:
Acta Histochemica et Cytochemica is the official online journal of the Japan Society of Histochemistry and Cytochemistry. It is intended primarily for rapid publication of concise, original articles in the fields of histochemistry and cytochemistry. Manuscripts oriented towards methodological subjects that contain significant technical advances in these fields are also welcome. Manuscripts in English are accepted from investigators in any country, whether or not they are members of the Japan Society of Histochemistry and Cytochemistry. Manuscripts should be original work that has not been previously published and is not being considered for publication elsewhere, with the exception of abstracts. Manuscripts with essentially the same content as a paper that has been published or accepted, or is under consideration for publication, will not be considered. All submitted papers will be peer-reviewed by at least two referees selected by an appropriate Associate Editor. Acceptance is based on scientific significance, originality, and clarity. When required, a revised manuscript should be submitted within 3 months, otherwise it will be considered to be a new submission. The Editor-in-Chief will make all final decisions regarding acceptance.
