Dhar KS, Townsend B, Montgomery AP, Danon JJ, Pagan JK, Kassiou M. Enhancing CNS mitophagy: drug development and disease-relevant models. Trends Pharmacol Sci 2024; 45:982-996. [PMID: 39419743 DOI: 10.1016/j.tips.2024.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2024] [Revised: 09/05/2024] [Accepted: 09/19/2024] [Indexed: 10/19/2024]
Abstract
Mitophagy, the selective degradation of mitochondria, is impaired in many neurodegenerative diseases (NDs), resulting in an accumulation of dysfunctional mitochondria and neuronal damage. Although enhancing mitophagy shows promise as a therapeutic strategy, the clinical significance of mitophagy activators remains uncertain due to limited understanding and poor representation of mitophagy in the central nervous system (CNS). This review explores recent insights into which mitophagy pathways to target and the extent of modulation necessary to be therapeutic towards NDs. We also highlight the complexities of mitophagy in the CNS, highlighting the need for disease-relevant models. Last, we outline crucial aspects of in vitro models to consider during drug discovery, aiming to bridge the gap between preclinical research and clinical applications in treating NDs through mitophagy modulation.

MICROPUBLICATION BIOLOGY 2024; 2024:10.17912/micropub.biology.001232. [PMID: 39011275 PMCID: PMC11247375 DOI: 10.17912/micropub.biology.001232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Figures] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 06/07/2024] [Accepted: 06/19/2024] [Indexed: 07/17/2024]
Abstract
Mitophagy, the selective removal of dysfunctional mitochondria, is pivotal for the maintenance of neuronal function and survival. MEC-12/α-tubulin contributes to neuronal physiology through the regulation of microtubule assembly, intracellular transport and mitochondrial distribution. However, its role in mitochondrial dynamics and mitophagy remains obscure. Here, we demonstrate that MEC-12 influences mitochondrial morphology under basal conditions and regulates the axonal mitochondrial population. Impairment of MEC-12 results in compromised axonal mitophagy under both basal conditions and oxidative stress. Our results uncover the critical role of MEC-12/α-tubulin for maintaining a healthy mitochondrial population in axons and highlight the complex interplay between microtubules, mitophagy and neuronal health.

Abstract
Unhealthy aging poses a global challenge with profound healthcare and socioeconomic implications. Slowing down the aging process offers a promising approach to reduce the burden of a number of age-related diseases, such as dementia, and promoting healthy longevity in the old population. In response to the challenge of the aging population and with a view to the future, Norway and the United Kingdom are fostering collaborations, supported by a "Money Follows Cooperation agreement" between the 2 nations. The inaugural Norway-UK joint meeting on aging and dementia gathered leading experts on aging and dementia from the 2 nations to share their latest discoveries in related fields. Since aging is an international challenge, and to foster collaborations, we also invited leading scholars from 11 additional countries to join this event. This report provides a summary of the conference, highlighting recent progress on molecular aging mechanisms, genetic risk factors, DNA damage and repair, mitophagy, autophagy, as well as progress on a series of clinical trials (eg, using NAD+ precursors). The meeting facilitated dialogue among policymakers, administrative leaders, researchers, and clinical experts, aiming to promote international research collaborations and to translate findings into clinical applications and interventions to advance healthy aging.
