Molecular aspects of cytoprotection by Optineurin during stress and disease.

Optineurin/OPTN is an adapter protein that plays a crucial role in mediating many cellular functions, including autophagy, vesicle trafficking, and various signalling pathways. Mutations of OPTN are linked with neurodegenerative disorders, glaucoma, and amyotrophic lateral sclerosis (ALS). Recent work has shown that OPTN provides cytoprotection from many types of stress, including oxidative stress, endoplasmic reticulum stress, protein homeostasis stress, tumour necrosis factor α, and microbial infection.

Psychological factors of parental physical activity support among parents of children with disabilities: a meta-analysis.

Purpose: Parents of children with disabilities often encounter challenges when supporting their child's physical activity (PA). Research on the psychological factors influencing parental support for PA has produced mixed results. The purpose of this meta-analysis was to a) synthesize psychological factors associated with parental support for PA, and b) evaluate the moderators of the association between parental support for PA and these psychological factors.

Gravity-Driven Separation for Enrichment of Rare Earth Elements Using Lanthanide Binding Peptide-Immobilized Resin.

Rare Earth Elements (REEs) constitute indispensable raw materials and are employed in a diverse range of devices, including but not limited to smartphones, electric vehicles, and clean energy technologies. While there is an increase in demand for these elements, there is a global supply challenge due to limited availability and geopolitical factors affecting their procurement. A crucial step in manufacturing these devices involves utilizing highly pure REEs, often obtained through complex and nonsustainable processes.

A cytoprotective role for optineurin during mycobacterial infection of macrophages.

Autophagy has emerged as a critical innate immune mechanism for host elimination of intracellular pathogens, however, the role of the autophagy receptor Optineurin during mycobacterial infection is not fully understood. To address this lacuna, we infected bone marrow-derived macrophages (BMDMs) derived from Optn and Optn mice with , and observed the infection outcome at sequential time points. While low multiplicity of infection (MOI) did not show any significant difference between BMDMs from the two groups, at high MOI Optn mice-derived BMDMs showed significantly lower colony forming unit counts, as well as lower cell counts at 12 h and 24 h post-infection.

Endocytic pathways of pathogenic protein aggregates in neurodegenerative diseases.

Endocytosis is the fundamental uptake process through which cells internalize extracellular materials and species. Neurodegenerative diseases (NDs) are characterized by a progressive accumulation of intrinsically disordered protein species, leading to neuronal death. Misfolding in many proteins leads to various NDs such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS) and other disorders.
