Brain autophagy is a process that allows your brain to regenerate, get rid of old and unhealthy cells, and replace them with new and healthier ones. The problem is that as you age, there is an increasing risk of brain degeneration. Leading an unhealthy lifestyle and toxic environmental factors can lead to a decline in brain health and function.

4 dec 2019 defective autophagy results in accumulation of toxic protein aggregates that detrimentally affect cellular function and organismal survival.
Autophagy has been recorded as the initial response of a cell to a toxic metal in a concentration- and time-dependent manner. Various signaling pathways are triggered through cellular proteins and/or protein kinases that can lead to autophagy, apoptosis (or necroptosis), and necrosis.
Most often, autophagy serves as a protective mechanism, but persistent activation of autophagy can result in cell death. In fact, there are ample examples of cross talk between autophagy and other modes of cell death after exposure to toxicants.

Toxicity and autophagy in neurodegenerative disorders evaluates the interplay between autophagy and toxicity in neurodegenerative disease contains contributions from an international group of experts addresses the major diseases: alzheimer's, parkinson's, huntington's.
The pathogenesis of the main neurodegenerative disorders includes either the accumulation of altered or misfolded proteins or exposure to several toxics. Autophagy constitute one of the two principal cellular pathways implicate in the clearance of these material and can serve as a neuroprotective mechanism.
Autophagy is considered an early indicator of nm interactions with cells and has been recently recognized as an important form of cell death in nanoparticle-induced toxicity. Impairment of autophagy is related to the accelerated pathogenesis of diseases.
Autophagy is a protein, macromolecular complex, and organelle degradation process that requires the assembly of a mixed protein/membrane structure (autophagosome) that targets and delivers substrates for degradation in the lysosome as illustrated below.
Macroautophagy [hereafter referred to as autophagy, see review by cuervo and wong (2014) for chaperone-mediated autophagy] is a conserved process for clearing of long-lived proteins, protein aggregates, dysfunctional cellular organelles and invaded pathogens, which is an essential mechanism for maintenance of cellular homeostasis (dikic and elazar, 2018). Recently, it has become apparent that autophagy plays a central role in development, aging, and neurodegeneration.

To assess the contribution of autophagy to tmt-induced neuronal cell death, we checked the vulnerability of neuronal cultures to tmt after activation or inhibition of autophagy. Our results show that autophagy inhibitors (3-methyladenine and l-asparagine) greatly enhanced tmt neurotoxicity. Conversely, known activators of autophagy, such as lithium and rapamycin, displayed neuroprotection against this toxic compound.
