Bromelain decreases oxidative stress and Neuroinflammation and improves motor function in adult male rats with cerebellar Ataxia induced by 3-acetylpyridine
Bromelain is a plant-based molecule with antioxidant, antithrombotic, anticancer, and anti-inflammatory properties. Bromelain has been shown to reduce the release of inflammatory cytokines. This study aimed to determine whether bromelain can prevent ataxia in rats caused by 3-acetylpyridine (3-AP). Thirty-six albino rats were divided into the control, 3-AP, and 3-AP + Brom groups. In the 3-AP + Brom group, bromelain was injected intraperitoneally at 40 mg/kg daily for 30 days. Various techniques such as rotarod, electromyography (EMG), elevated plus maze, IHC, and Sholl analysis were used to evaluate the possible effects of bromelain on cerebellar neurons and glial cells. The results demonstrated significant improvements in most of the 3-AP + Brom, including motor coordination, neuromuscular response, anxiety, oxidative capacity, microgliosis, astrogliosis, cell death, and morphological variables compared to the 3-AP group. The mechanism of action of bromelain in restoring cerebellar ataxia needs further investigation, but it may be a candidate to help restore degeneration in animals with ataxia.
期刊介绍:
The aim of Neuropeptides is the rapid publication of original research and review articles, dealing with the structure, distribution, actions and functions of peptides in the central and peripheral nervous systems. The explosion of research activity in this field has led to the identification of numerous naturally occurring endogenous peptides which act as neurotransmitters, neuromodulators, or trophic factors, to mediate nervous system functions. Increasing numbers of non-peptide ligands of neuropeptide receptors have been developed, which act as agonists or antagonists in peptidergic systems.
The journal provides a unique opportunity of integrating the many disciplines involved in all neuropeptide research. The journal publishes articles on all aspects of the neuropeptide field, with particular emphasis on gene regulation of peptide expression, peptide receptor subtypes, transgenic and knockout mice with mutations in genes for neuropeptides and peptide receptors, neuroanatomy, physiology, behaviour, neurotrophic factors, preclinical drug evaluation, clinical studies, and clinical trials.
