Summary: In this study, the innate immune reaction in the midbrain and striatum of Parkinson's disease was assessed. The results showed that CD11b(+) cells in the parkinsonian midbrain presented an anti-inflammatory profile, while CD11b(+) cells in the striatum showed a pro-inflammatory state. Astrocytes exhibited a pro-inflammatory fingerprint in the midbrain. The findings highlight the importance of selecting appropriate cell targets to design neuroprotective strategies in the active phase of dopaminergic degeneration.

Summary: Parkinson's disease (PD) is a characteristic disease characterized by motor symptoms due to the loss of dopaminergic neurons and non-motor symptoms that precede motor symptoms. The transmission of Parkinson's disease is thought to propagate from the enteric nervous system to the central nervous system, accompanied by an accumulation of alpha-synuclein. Metallothioneins (MTs) are cysteine-rich metal-binding proteins that can inhibit oxidative stress, inflammation, and mitochondrial dysfunction caused by metals. MTs also have antioxidative and anti-inflammatory effects. This review highlights the protective functions of MTs and their potential as a target for the development of disease-modifying drugs for PD.

Summary: Iron plays a fundamental role in various aspects of human life, but an imbalance in iron levels can lead to certain pathologies. Maintaining iron homeostasis is crucial in preventing these pathologies. While there is evidence suggesting iron's involvement in the degenerative process of Parkinson's disease, clinical studies have not shown positive effects of iron chelators in treating the disease.

Summary: Vitamin D plays a crucial role in bone metabolism, calcium and phosphorous homeostasis, as well as brain development and neuroprotection. Patients with Parkinson's disease often have a high frequency of vitamin D deficiency, which may be related to disease severity and progression. However, the evidence regarding the use of vitamin D supplementation to reduce symptoms and disability in patients with Parkinson's disease is limited. Further clinical studies are needed to confirm the potential benefits and risks of vitamin D supplementation in this population.

Summary: Alzheimer's and Parkinson's are neurodegenerative disorders that seriously affect people's quality of life. This review used Molecular Docking to evaluate the potential of linalool, citronellal, and their derivatives as anti-Alzheimer's and anti-Parkinson's agents. The compounds demonstrated good pharmacokinetic characteristics and showed strong affinity for targets involved in the pathophysiology of these diseases. Linalool and its derivatives also exhibited promise against the BACE enzyme activity associated with Alzheimer's disease. These compounds have the potential to be developed into future drugs for the treatment of neurodegenerative disorders.

Summary: Activation of PPAR beta/delta has been shown to alleviate depressive behaviors and promote mitophagy in astrocytes. In vitro experiments demonstrated that PPAR beta/delta agonist GW0742 reduces mitochondrial oxidative stress and inhibits ER stress-mediated apoptosis pathway. The findings suggest that PPAR beta/delta activation protects against ER stress-induced astrocytic apoptosis by enhancing UCP2-mediated mitophagy, contributing to its anti-depressive action.

Summary: This study demonstrates the imbalance of netrin-1 (NTN-1) and deleted in colorectal carcinoma (DCC) signaling in the progression of Parkinson's disease (PD). Through the establishment of experimental PD models, it was found that the imbalance of NTN-1 and DCC is a common feature of nigral dopaminergic neuron injury. Further experiments revealed that MPP+ inhibits NTN-1 expression and increases DCC expression. Additionally, a significant decrease in plasma NTN-1 levels and a positive correlation with UPDRS scores were observed in PD patients.

Summary: Neutrophil aggregation and clearance play crucial roles in neuroinflammatory injury during acute ischemic stroke. The study shows that Resolvin D1 (RvD1), a lipid mediator derived from docosahexaenic acid (DHA), promotes microglial phagocytosis of neutrophils, reducing neutrophil accumulation in the brain and alleviating neuroinflammation. RvD1 reprograms energy metabolism from glycolysis to oxidative phosphorylation (OXPHOS), providing sufficient energy for microglial phagocytosis. Moreover, RvD1 enhances microglial glutamine uptake and stimulates glutaminolysis to support OXPHOS via AMP-activated protein kinase (AMPK) activation.

Summary: This study investigated the effects of age on the robustness and resilience of auditory system using the desert locust. The researchers found that gene expression changes were mainly influenced by age rather than noise exposure. Both young and aged locusts were able to recover their auditory nerve function within 48 hours of noise exposure, but the recovery of transduction current magnitude was impaired in aged locusts. Key genes responsible for robustness to noise exposure in young locusts and potential candidates for compensatory mechanisms in auditory neurons of aged locusts were identified.
