“… 9 Also, p75 NTR with the help of the nogo-66 receptor (NgR1) induces apoptosis and inhibits neuronal myelin sheath. 10 The effects of diverse signaling pathways, such as NF-κB, which plays a crucial role in the advancement and progression of neurodegenerative disorders, are mediated by p75 NTR 11 ( Figure 1 ).

Epilepsy is a chronic neurological disorder manifested by recurring unprovoked seizures resulting from an imbalance in the inhibitory and excitatory neurotransmitters in the brain. The process of epileptogenesis involves a complex interplay between the reduction of inhibitory gamma-aminobutyric acid (GABA) and the enhancement of excitatory glutamate. Pro-BDNF/p75NTR expression is augmented in both glial cells and neurons following epileptic seizures and status epileptics (SE). Over-expression of p75NTR is linked with the pathogenesis of epilepsy, and augmentation of pro-BDNF/p75NTR is implicated in the pathogenesis of epilepsy. However, the precise mechanistic function of p75NTR in epilepsy has not been completely elucidated. Therefore, this review aimed to revise the mechanistic pathway of p75NTR in epilepsy.

An estimated 10–20% of adolescents experience mental health conditions, and most of them remain underdiagnosed and undertreated. Discovering new susceptibility biomarkers is therefore important for identifying individuals at high risk of developing mental health problems, and for improving early prevention. Here we aimed to discover plasma protein-based susceptibility biomarkers in children/adolescents aged 11–16 years at risk of developing mental health issues. Risk was evaluated on the basis of self-reported Strengths and Difficulties Questionnaire (SDQ) scores, and plasma proteomic data were obtained for individuals participating in the Spanish WALNUTs cohort study by liquid chromatography–tandem mass spectrometry. Bioinformatic analyses were performed to identify the biological processes and pathways in which the identified biomarker candidates are involved; 58 proteins were significantly associated with the SDQ score. The most prominent enriched pathways related to these proteins included immune responses, blood coagulation, neurogenesis and neuronal degeneration. This exploratory study revealed several alterations of plasma proteins associated with the SDQ score in adolescents, which opens a new avenue to develop novel susceptibility biomarkers to improve early identification of individuals at risk of mental health problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
