MiR129-5p-loaded exosomes suppress seizure-associated neurodegeneration in status epilepticus model mice by inhibiting HMGB1/TLR4-mediated neuroinflammation.

Background: Neuroinflammation contributes to both epileptogenesis and the associated neurodegeneration, so regulation of inflammatory signaling is a potential strategy for suppressing epilepsy development and pathological progression. Exosomes are enriched in microRNAs (miRNAs), considered as vital communication tools between cells, which have been proven as potential therapeutic method for neurological disease. Here, we investigated the role of miR129-5p-loaded mesenchymal stem cell (MSC)-derived exosomes in status epilepticus (SE) mice model.

Serum glial cell line-derived neurotrophic factor (GDNF) a potential biomarker of executive function in Parkinson's disease.

Objective: Evidence shows that the impairment of executive function (EF) is mainly attributed to the degeneration of frontal-striatal dopamine pathway. Glial cell line-derived neurotrophic factor (GDNF), as the strongest protective neurotrophic factor for dopaminergic neurons (DANs), may play a role in EF to some extent. This study mainly explored the correlation between serum GDNF concentration and EF performance in Parkinson's disease (PD).

Compensatory Base Changes and Varying Phylogenetic Effects on Angiosperm ITS2 Genetic Distances.

A compensatory base change (CBC) that coevolves in the secondary structure of ribosomal internal transcribed spacer 2 (ITS2) influences the estimation of genetic distance and thus challenges the phylogenetic use of this most popular genetic marker. To date, however, the CBC effect on ITS2 genetic distance is still unclear. Here, ITS2 sequences of 46 more recent angiosperm lineages were screened from 5677 genera and phylogenetically analyzed in sequence-structure format, including secondary structure prediction, structure-based alignment and sequence partition of paired and unpaired regions.

Down-Regulated CUEDC2 Increases GDNF Expression by Stabilizing CREB Through Reducing Its Ubiquitination in Glioma.

Abnormally high expression of glial cell line-derived neurotrophic factor (GDNF) derived from glioma cells has essential impacts on gliomagenesis and development, but the molecular basis underlying increased GDNF expression in glioma cells remain unclear. This work aimed to study the molecular mechanisms that may explain the accumulation of GDNF in glioma. Firstly, we observed that cAMP response element-binding protein (CREB), known as an important transcription factor for binding of GDNF promoter region, was highly expressed with an apparent accumulation into the nucleus of glioma cells, which may contribute to the transcription of GDNF.

Serum levels of glial cell line-derived neurotrophic factor and multiple neurotransmitters: In relation to cognitive performance in Parkinson's disease with mild cognitive impairment.

Objectives: Mild cognitive impairment is a common non-motor feature of Parkinson's disease, termed PD-MCI. But there is a scarcity of data on the role of glial cell line-derived neurotrophic factor (GDNF) and neurotransmitters in pathogenesis of PD-MCI. The aim of this project was to detect the serum levels of GDNF and multiple neurotranmitters and explore their relationships with cognitive performance in PD-MCI patients.

Cross-link regulation of precursor N-cadherin and FGFR1 by GDNF increases U251MG cell viability.

Glial cell line-derived neurotrophic factor (GDNF) is considered to be involved in the development of glioma. However, uncovering the underlying mechanism of the proliferation of glioma cells is a challenging work in progress. We have identified the binding of the precursor of N-cadherin (proN-cadherin) and GDNF on the cell membrane in previous studies.

Memory Impairment Due to a Small Acute Infarction of the Columns of the Fornix.

Background: Clinically infarction of the columns of the fornix is very rare. It is also easy to be overlooked during imaging examination due to the special anatomical localization and features of columns of the fornix. In the meantime, with memory disorder to be its most prominent manifestation, it is very easily false diagnosed as other diseases when the lesion focus is overlooked, causing unnecessary invasive examinations like cerebrospinal fluid tests.
