Abstract
3-Nitropropionic acid (3-NP) is strongly believed to be an irreversible inhibitor of mitochondrial complex II, leading to neural damage. This study aimed to investigate the neuroprotective effects of silymarin against 3-NP-induced neurotoxicity in male mice. Six-week-old mice received subacute doses of 3-NP intraperitoneally for 17 days. Mice were given silymarin (70 mg/kg/day, P.O.) for 2 weeks before 3-NP administration or for 4 weeks after 3-NP administration. At the end of the treatment schedule, animals were evaluated for behavioral alterations. Subsequently, neuronal damage in the hippocampus region of the brain tissues, oxidative stress-related parameters (lipid peroxidation, nitric oxide, superoxide dismutase, glutathione, and total antioxidant capacity), and pro-inflammatory cytokine (TNF-α, IL-17, and IL-1β) levels were evaluated. Our results indicated that 3-NP treatment significantly (p < 0.05) tended to reduce motor coordination, memory, and neuronal antioxidant status while increasing pro-inflammatory cytokine levels. However, silymarin in both treatment and pretreatment protocols markedly (p < 0.05) attenuated the behavioral deficits, oxidative stress status, and neuroinflammation. The results of the current study suggest that the neuroprotective effect of silymarin against 3-NP-induced neurotoxicity might be due to the mitigation of oxidative stress status and provide insight into the therapeutic potential of silymarin.

Abstract
3-nitropropionic acid (3-NP) is a potent mitochondrial inhibitor mycotoxin. Systemic administration of 3-NP can induce Huntington's disease (HD)-like symptoms in experimental animals. Safranal (Safr) that is found in saffron essential oil has antioxidant, anti-inflammatory and anti-apoptotic actions. Candesartan (Cands) is an angiotensin receptor blocker that has the potential to prevent cognitive deficits. The present study aims to investigate the potential neuroprotective efficacy of Safr or Cands in 3-NP-induced rat model of HD. The experiments continued for nine consecutive days. Rats were randomly assigned into seven groups. The first group (Safr-control) was daily intraperitoneally injected with paraffin oil. The second group (Cands- and 3-NP-control) daily received an oral dose of 0.5% carboxymethylcellulose followed by an intraperitoneal injection of 0.9% saline. The third and fourth groups received a single daily dose of 50 mg/kg Safr (intraperitoneal) and 1 mg/kg Cands (oral), respectively. The sixth group was daily treated with 50 mg Safr kg/day (intraperitoneal) and was intraperitoneally injected with 20 mg 3-NP/ kg, from the 3rd till the 9th day. The seventh group was daily treated with 1 mg Cands /kg/day (oral) and was intraperitoneally injected with 20 mg 3-NP/ kg, from the 3rd till the 9th day. The present results revealed that 3-NP injection induced a considerable body weight loss, impaired memory and locomotor activity, reduced striatal monoamine levels. Furthermore, 3-NP administration remarkably increased striatal malondialdehyde and nitric oxide levels, whereas markedly decreased the total antioxidant capacity. Moreover, 3-NP significantly upregulated the activities of inducible nitric oxide synthase and caspase-3 as well as the Fas ligand, in striatum. On the contrary, Safr and Cands remarkably alleviated the above-mentioned 3-NP-induced alterations. In conclusion, Safr and Cands may prevent or delay the progression of HD and its associated impairments through their antioxidant, anti-inflammatory, anti-apoptotic and neuromodulator effects.

Abstract
Calcium (Ca 2+) is an important second messenger in charge of many critical processes in the central nervous system (CNS), including membrane excitability, neurotransmission, learning, memory, cell proliferation, and apoptosis. In this way, the voltage-gated calcium channels (VGCCs) act as a key supply for Ca2+ entry into the cytoplasm and organelles. Importantly, the dysregulation of these channels has been reported in many neurological diseases of young-onset, with associated genetic factors, such as migraine, multiple sclerosis, and Huntington's disease. Notably, the literature has pointed to the role of N-type Ca2+ channels (NTCCs) in controlling a variety of processes, including pain, inflammation, and excitotoxicity. Moreover, several Ca2+ channel blockers that are used for therapeutic purposes have been shown to act on the N-type channels. Therefore, this review provides an overview of the NTCCs in neurological disorders focusing mainly on Huntington's disease, multiple sclerosis, and migraine. It will discuss possible strategies to generate novel therapeutic strategies.

Abstract
NEW FINDINGS What is the central question of this study? We investigated the action of intrathecal administration of a novel toxin (CTK01512-2) in a mouse model for Huntington´s disease (HD). We asked if spinal cord neurons can represent a therapeutic target, as the spinal cord seems to be involved in HD motor-symptoms. Pharmacological approaches focusing on the spinal cord and skeletal muscles might represent a more feasible strategy. What is the main finding and its importance? We provided evidence of a novel, local, neuroprotector effect of CTK01512-2, paving a path for the development of approaches to treat HD-motor symptoms beyond the brain. ABSTRACT Phα1β is a neurotoxin from the venom of the Phoneutria nigriventer spider, available as CTK01512-2, a recombinant peptide. Due to its antinociceptive and analgesic properties, CTK01512-2 has been described to alleviate neuroinflammatory responses. Despite the diverse CTK01512-2 actions on the nervous system, little is known regarding its neuroprotective effect, especially in neurodegenerative conditions such as Huntington's disease (HD), a genetic movement disorder without cure. Here, we investigated whether CTK01512-2 has a neuroprotector effect in a mouse model of HD. We hypothesized that spinal cord neurons might represent a therapeutic target, as the spinal cord seems to be involved in the motor-symptoms of HD mice (BACHD). Then, we treated BACHD mice with CTK01512-2 by intrathecal injection, and performed in vivo motor behavior and morphological analyses in the central nervous system (brain and spinal cord) and muscles. Our data showed that intrathecal injection of CTK01512-2 significantly improves motor-performance in the Open-field task. CTK01512-2 protects neurons in the spinal cord (but not in the brain) from death, suggesting a local effect. CTK01512-2 exerts its neuroprotective effect by inhibiting BACHD-neuronal apoptosis, as revealed by a reduction in caspase-3 in the spinal cord. CTK01512-2 was also able to revert BACHD muscle atrophy. In conclusion, our data provide a novel role for CTK01512-2 acting directly in the spinal cord, ameliorating morphofunctional aspects of spinal cord neurons, and muscles, and improving BACHD mice performance in motor-behavioral tests. Since HD shares similar symptoms to many neurodegenerative conditions, the findings presented herein may also be applicable to other disorders. This article is protected by copyright.
