Understandings of the disturbed iron metabolism in Parkinson's disease (PD) are largely from the perspectives of neurons. Neurodegenerative processes in PD trigger universal and conserved astroglial dysfunction and microglial activation. In this review, we start with astroglia and microglia in PD with an emphasis on their roles in spreading α-synuclein pathology, and then focus on their contributions in iron metabolism under normal conditions and the diseased state of PD. Elevated iron in the brain regions affects glial features, meanwhile, glial effects on neuronal iron metabolism are largely dependent on their releasing factors. These advances might be valuable for better understanding and modulating iron metabolism disturbance in PD.

The self-assembled ferritin protein nanocage plays a pivotal role during oxidative stress, iron metabolism, and host-pathogen interaction by executing rapid iron uptake, oxidation and its safe-storage. Self-assembly creates a nanocompartment and various pores/channels for the uptake of charged substrates (Fe) and develops a concentration gradient across the protein shell. This phenomenon fuels rapid ferroxidase activity by an upsurge in the substrate concentration at the catalytic sites.

Background: Mendelian randomization is believed to attenuate the biases inherent in observational studies, yet a meta-analysis of Mendelian randomization studies in osteoporosis has not been conducted thus far. This study aims to evaluate the connection between potential causal factors and the risk of osteoporosis by synthesizing evidence from Mendelian randomization studies.
Methods: The databases PubMed, Web of Science, and Embase were systematically searched for Mendelian randomization studies investigating factors influencing osteoporosis up to May 2024.

Malaria and hypertension are seemingly unrelated communicable and non-communicable diseases, both highly pervasive in the global south. There is a debate about the potential connection between these two disorders beyond any obvious factors. The emerging evidence suggests an emerging genetic selection pressure for hypertension in malaria-endemic regions.

Background: Beta thalassemia major (β-TM) is a severe genetic anemia with considerable phenotypic heterogeneity. This study investigated whether genotype correlates with distinct myocardial iron overload patterns, assessed by cardiovascular magnetic resonance (CMR) T2* values.
Methods: CMR data for cardiac iron deposition evaluation, which recruited pediatric participants between January 2021 and December 2024, were analyzed with CVI42.
