TRE

Symbol: TRE
Name: Trehalose


Observation:

In nematodes treatment with trehalose starting from the young-adult stage extends the mean lifespan by over 30% without any side effects. Trehalose treatment starting even from the old-adult stage shortly thereafter retards the age-associated decline in survivorship and extends the remaining lifespan by 60%. Lifespan extension by trehalose lowers the age-independent vulnerability. Trehalose increases reproductive span and retards the age-associated decrease in pharyngeal-pumping rate and the accumulation of lipofuscin autofluorescence as well as enhances thermotolerance and reduces polyglutamine. The lifespan extending effect of trehalose is abolished in daf-2 mutants [20477758].

Trehalose is suggested to act as a stress protectant against heat, cold, desiccation, anoxia, and oxidation [20477758].

Treatment with trehalose reduces neurodegeneration in a transgenic mouse model of taupathy (human mutant P301S tau mouse. Neuronal survival is evaluated by trehalose. Trehalose induces autophagy in the brain, where the number of neurons containing tau inclusions is significantly reduced as well as the amount of insoluble tau protein and the protein levels of p62. However, trehalose fails to activate autophagy in the spinal cord, where it has no impact on the level of sarkosyl-insoluble tau. Trehalose has also no effect on the motor impairment of human mutant P301S tau transgenic mice [22689910].
