Other discoveries indicate that interactions with nutrient-sensing pathways and glucose transporter systems that simulate metabolic stress, which may activate protective mechanisms separate from the inhibition of mTOR. Trehalose could also involve in lysosomal-autophagosome fusion and modulate the microglia and astrocytes activation, suggesting an important immunometabolic function. Trehalose often connects to the gut-brain axis and show their effect in gut microbiota composition, microbial metabolite signalling and gut barrier function.
