What are Heat Shock Proteins? When cells are exposed to stressful situations, they respond by creating heat shock proteins. Since the first type of stress found to activate these proteins was heat, the proteins were named heat shock proteins. Other triggers of heat shock proteins in the body include cold temperatures, ultraviolet light, heavy metals, […]

The role of molecular chaperones, such as heat shock protein 70 (Hsp70), is not typically studied as a function of biological sex, but by addressing this gap we might improve our understanding of proteinopathic disorders that predominate in one sex. Therefore, we exposed male or female primary hippocampal cultures to preformed α-synuclein fibrils in a

Patients with Parkinson’s disease present with signs and symptoms of dysregulation of the peripheral autonomic nervous system that can even precede motor deficits. This dysregulation might reflect early pathology and therefore could be targeted for the development of prodromal or diagnostic biomarkers. Only a few objective clinical tests assess disease progression and are used to

The human microbiota comprises trillions of symbiotic microorganisms and is involved in regulating gastrointestinal (GI), immune, nervous system and metabolic homeostasis. Recent observations suggest a bidirectional communication between the gut microbiota and the brain via immune, circulatory and neural pathways, termed the Gut-Brain Axis (GBA). Alterations in gut microbiota composition, such as seen with an
The ketogenic diet (KD) is a high-fat, low-carbohydrate diet, in which fat is used as the primary energy sourcethrough the production of ketone bodies (KBs) in place of glucose. The KD was formally introduced in 1921 tomimic the biochemical changes associated with fasting and gained recognition as a potent treatment for pediatricepilepsy in the mid-1990s.

Rapid eye movement (REM) sleep behavior disorder (RBD), enactment of dreams during REM sleep, isan early clinical symptom of alpha-synucleinopathies. RBD also defines more severe forms of alphasynucleinopathies. The genetic background of RBD and its underlying mechanisms are not wellunderstood. Here, we performed the first genome-wide association study of RBD, identifying five RBD riskloci. Expression
Our study firstly applied a two-sample MR approach to detect causal relationships among gut microbiota, gut metabolites and the risk of AD, PD and ALS, andwe revealed several causal relationships. These findings may provide new targets for treatment of these neurodegenerative diseases, and may offer valuableinsights for further researches on the underlying mechanisms. In summary,
A significant improvement of cognitive functions, in terms of short-termmemory, attention, and executive performance, as well as ofpsychophysiological markers, such as salivary cortisol level,skin conductance, sleep quality, and anxiety, were observed.Conclusions: According to the results, L. reuteri PBS072 andB. breve BB077 are potential probiotic candidates for improving stress resilience, cognitive functions, and sleep quality CLICK

This chapter contrasts the prion-like behavior of alphasynuclein in Parkinson’s disease with other prion diseases.In prion diseases, the infectious, amyloid form of theprotein induces the corresponding normally folded proteinto assume the toxic fold, spreading the disease and slowlydestroying the brains of infected patients. Lewy pathologyin Parkinson’s disease appears to spread in a mannersimilar to that
Parkinson’s disease (PD) is a complex brain disorder involving a multitude ofcontributing factors ranging from environmental to genetic. Interestingly, it has been foundthat the gut microbial community is altered in PD patients when compared to that of non-PDindividuals. However, the factors contributing to altered gut microbiota remain largelyunexplored. As such, the first objective of our
