They have analyzed plasma and brain level of curcumin in an animal model and found with 0. This is also reminding that the traditional method of dissolving turmeric in fat during cooking in South East Asian people is likely an effective method to improve its solubility and bioavailability.
However, the uses of different lipidated formulas including nanoparticle coated curcumin deliveries are in their beginning stage; need much more development for its successful therapeutic use.
Potential Impact of Nanocurcumin in Activation of Heat Shock System Despite strong evidence supporting multiple roles of HSPs in amyloid protein degradation [ 21 , 24 , 34 , ], knowledge of their dysregulation in different neurodegenerative diseases and their potential as a drug target is unclear. Further, the relationships between the beta-pleated sheet binding of curcumin and removal of these protein aggregates are poorly understood. One possibility is that it is targeting a common endogenous protein clearance pathway, such as the HSP system.
Research from Frautschy group support the idea that curcumin administration decreases tau protein aggregation in human tau transgenic HtauTg mouse model [ 13 ]. They have demonstrated that curcumin has also been shown to reduce soluble tau and increase HSPs in a human tau mouse model [ 25 ]. These results indicate that even after tangles are established, tau-dependent dysfunction of the synapses and behavior deficits can be corrected by curcumin treatment [ 13 , 25 ].
Therefore, curcumin might be the promising compounds, which can modulate as well as rectify dysregulation of the heat shock response; their co-chaperones and client proteins in different brain disorders need further investigation. For AD animal model, triple transgenic rat Swedish mutation in APP and mutation in presenilin-1 and presenilin-2 was used.
Both tauopathies and AD animal models showed significant cognitive and neurobehavioral impairments along with significant neuropathological symptoms [ 13 , 25 ]. However, the HD mice were pretreated with ppm regular curcumin and rests two are treated with same doses of solid lipid nanoparticle coated curcumin.
The reason for choosing low dose of curcumin is because higher doses e. However, in our study we been found that there were transgene-dependent reductions of HSPs response along with decline some of their client proteins in all these three neurodegenerative animal models, indicating molecular chaperones are highly affected, whereas, curcumin restored transgenic defects of these proteins unpublished observation.
Another line of interest in this context was whether curcumin could modulate HSP90 co-chaperones and their client proteins. The immunophillin FKBP51 is a mitochondrial protein that translocate to the nucleus to protect cells against oxidative stress [ ], and its level has been reported to reduce in AD brain [ ].
It has been observed that CDC37, P23 and FKBP51 were significantly reduced in all the three animal models, suggesting that there was dysregulation of HSP90 co-chaperones, whereas curcumin treatment ameliorated their levels.
It is observed that even 0. These observations indicate that very low amount of curcumin may be required for neuroprotection as well as to activate cellular HSS, but definitely need further investigations to confirm these findings. Conclusion Accumulation of misfolded proteins in the intra and extracellular spaces of the central nervous system are the leading cause of synaptic loss, neurodegeneration, and cognitive and behavioral impairment in several brain diseases.
Endogenous protein clearance pathway such as HSPs have significant role in protein folding and maturation, and renaturation of misfolded proteins, thus play pivotal role to remove these aggregated proteins. This essential system is significantly down regulated in different brain diseases. Recently, anti-amyloid polyphenol curcumin have been found to be an ameliorative role against amyloid induced dysregulation of HSS.
Increase solubility, stability and bioavailability of curcumin by nanocurcumin formulation are the promising strategies for restoration and up-regulation of HSS to rectify the deleterious effect in several neurodegenerative diseases caused by misfolded proteins accumulation.
