Atmospheric pollution-induced cellular oxidative stress is probably one of the pathogenic mechanisms involved in most of the common autophagy-mediated aging diseases, including neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Alzheimer's, disease, as well as Paget's disease of bone with or without frontotemporal dementia and inclusion body myopathy. Oxidative stress has serious damaging effects on the cellular contents: DNA, RNA, cellular proteins, and cellular organelles. Autophagy has a pivotal role in recycling these damaged non-functional organelles and misfolded or unfolded proteins. In this paper, we highlight, through a narrative review of the literature, that when autophagy processes are impaired during aging, in presence of cumulative air pollution-induced cellular oxidative stress and due to a direct effect on air pollutant, autophagy-mediated aging diseases may occur.

Background: Senile dementia (SD) is a deteriorative organic brain disorder and it comprises Alzheimer's disease (AD) as a major variant. SD is shown impairment of mental capacities whereas AD is degeneration of neurons. According to World Health Organization (WHO) report; more than 55 million peoples have dementia and it is raising 10 million new cases every year.

Background: Developing drugs for treating Alzheimer's disease (AD) has been extremely challenging and costly due to limited knowledge on underlying biological mechanisms and therapeutic targets. Repurposing drugs or their combination has shown potential in accelerating drug development due to the reduced drug toxicity while targeting multiple pathologies.
Method: To address the challenge in AD drug development, we developed a multi-task machine learning pipeline to integrate a comprehensive knowledge graph on biological/pharmacological interactions and multi-level evidence on drug efficacy, to identify repurposable drugs and their combination candidates RESULT: Using the drug embedding from the heterogeneous graph representation model, we ranked drug candidates based on evidence from post-treatment transcriptomic patterns, mechanistic efficacy in preclinical models, population-based treatment effect, and Phase 2/3 clinical trials.

Background: Parkinson's disease is an hypokinetic disorder characterized by selective loss of dopaminergic in substantia nigra pars compacta (SNPc) region of mid-brain. Dopaminergic degeneration of neurons is considered to be due to oxidative stress, neuroinflammation, neurons mitochondrial dysfunction and glutamate excitotoxicity etc. Filgrastim has been reported to produce anti-oxidant, anti-inflammatory and neuromodulatory actions in previous studies.

Background: The impact of probiotics as gut and immunological modulator in restoring gut microbial balance and immune cells expression have generated much attention in the health sector. Its inhibitory effect on bacterial translocation and associated neural inflammatory processes has been reported. However, there is scarcity of data on its neuroprotective impact against neuroinflammation-associated neurodegeneration and memory impairment.

Background: Cyclin Y (CCNY) is a member of cyclin protein family inhibiting long-term synaptic plasticity, which is related to the learning and memory function in neuronal system. Recently, CCNY has been reported to associate with the cognitive deficits in Alzheimer's disease (AD).
Method: In this study, we discovered PFTAIRE peptide to diminish CCNY protein level and to ameliorate cognitive dysfunction in AD.
