Inflammatory pathways in Alzheimer's disease mediated by gut microbiota.

In the past decade, numerous studies have demonstrated the close relationship between gut microbiota and the occurrence and development of Alzheimer's disease (AD). However, the specific mechanism is still unclear. Both the neuroinflammation and systemic inflammation serve as the key hubs to accelerate the process of AD by promoting pathology and damaging neuron.

Neurodevelopmental disorder caused by a truncating de novo variant of IRF2BPL.

Background: Mutations in the IRF2BPL gene can cause neurodevelopmental disorders. We describe the clinical and genetic characteristics of a Chinese patient with a novel abnormality in this gene, explore the potential pathogenic mechanism and summarize the clinical characteristics of 25 patients with IRF2BPL mutations.

Methods: We identified the gene mutation sites by whole-exome and Sanger sequencing.

Altered structural and functional connectivity in CSF1R-related leukoencephalopathy.

CSF1R-related leukoencephalopathy is a rare white-matter encephalopathy characterized by motor and neuropsychiatric symptoms due to colony-stimulating factor 1 receptor (CSF1R) gene mutation. Few studies have investigated the intrinsic brain alternations of patients with CSF1R-related leukoencephalopathy. We aim to evaluate the structural and functional changes in those patients.
