Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system. Nearly 85% of MS patients are recognized with relapsing-remitting MS (RRMS), a typical clinical course of disease which is distinguished by several episodes of relapses, separated by remissions of neurological impairment. Failure of repair mechanisms is a main factor in progression of neurological dysfunction in MS. Several lines of evidence suggest that Reelin (RELN) signaling pathway can contribute in the regulation of repair mechanisms in MS patients. In the present study, we assessed expression levels of RELN and Disabled-1 (DAB1), two key genes in RELN signaling pathway, in peripheral blood of 50 RRMS patients and 50 matched healthy subjects. RELN was significantly down-regulated in total MS patients, and total female patients compared with the matched controls. However, no statistically significant difference was found in DAB1 mRNA expression between MS patients and controls. Furthermore, considerable correlations were detected between expression levels of RELN and DAB1 in the patients group. There were no significant correlations between expression levels of genes and EDSS, disease duration or age at onset. Our study provides evidences for the role of RELN signaling pathway in the pathogenesis of MS. Further studies are required to clarify the exact clinical significance of this pathway in MS patients.

A substantial portion of patients infected with SARS-CoV-2 experience prolonged complications, known as Long COVID (LC). A subset of these patients exhibits the most debilitating symptoms, similar to those defined in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). We performed bulk RNA sequencing (RNAseq) on the whole blood of LC with ME/CFS, at least 12 months post-onset of the acute disease, and compared them with controls.

Objective: Epilepsy involves significant changes in neural cells during epileptogenesis. Although the molecular mechanism of epileptogenesis remains obscure, changes in gene regulation play a crucial role in the evolution of epilepsy. This study aimed to compare changes in a subset of specific genes during epilepsy development, focusing on the period after the first spontaneous seizure, to identify critical time windows for targeting different regulators.

Article Synopsis
- GABAergic interneurons are crucial for maintaining a balance between excitation and inhibition in the brain, particularly in the prefrontal cortex (PFC); an overload of glucocorticoids, like dexamethasone (DEX), can disrupt these cells and increase vulnerability to mental health issues such as depression and anxiety.
- In a study with adult male mice, chronic DEX treatment led to observed behaviors resembling depression and anxiety, as well as reduced levels of important GABAergic markers and a decrease in brain size and cortex thickness.
- The findings suggest that the decline in GABAergic interneurons due to high DEX exposure may contribute to emotional and behavioral deficits, pointing towards a potential link between glucocorticoid

Article Synopsis
- * By using immunofluorescence staining, researchers analyzed the protein expressions of different connexins (Cx37, Cx40, Cx43, Cx45) and related proteins (Dab1, Reelin) at two embryonic stages (E13.5 and E15.5).
- * The findings showed distinct expression patterns among the connexins, suggesting that these proteins might influence retinal development and could be potential targets for treating retinal diseases.
