Article Synopsis
  • Extracellular vesicles (EVs) are tiny particles released by all cells and have a significant role in communication, shuttling substances, and modulating the immune system, especially relevant in multiple sclerosis (MS) research.
  • The study focused on mouse models of MS to analyze the changes in EVs from the spinal cord at different stages of the disease, revealing shifts in proteins related to inflammation and synaptic function.
  • The findings indicate that EVs reflect critical disease mechanisms in the central nervous system (CNS) and suggest potential biomarkers for MS, with similarities between changes in EVs in experimental models and those seen in human MS patients.

Single-cell chemical and metabolic imaging technologies provide unprecedented insights into individual cell dynamics, advancing our understanding of cellular processes, molecular interactions, and metabolic activities. Advances in fluorescence, Raman, optoacoustic (photoacoustic), or mass spectrometry methods have paved the way to characterize metabolites, signaling molecules, and other moieties within individual cells. These modalities can also lead to single-cell imaging capabilities by targeting endogenous cell contrast or by employing exogenous contrast generation techniques, including contrast agents that target specific cell structure or function.

Multiple sclerosis (MS) has traditionally been viewed as a chronic inflammatory disease affecting the white matter of the central nervous system. However, over the past two decades, increasing evidence has highlighted the role of gray matter pathology in MS-related disability. Numerous studies have linked the presence of leptomeningeal inflammation to a more severe disease course, underscoring its potential importance as a driver of gray matter pathology in MS.

Multiple sclerosis (MS) is an inflammatory disease of the central nervous system that finally leads to demyelination. Demyelinating optic neuritis is a frequent symptom in MS. Recent studies also revealed synapse dysfunctions in MS patients and MS mouse models.

Herpes simplex virus-2 (HSV-2) infection is the most common cause of genital ulcers. The impact of ulcers also demonstrates a strong link to the human immunodeficiency virus (HIV) infection. Complications, drug resistance, and side-effects of anti-viral drugs make the treatment of HSV-2 infection challenging.

Article Synopsis
  • * Researchers used mouse models to show that immune responses attack ribbon synapses in the retina before any damage to the optic nerve occurs.
  • * This autoimmune attack involves proteins at both myelinated nerves and retinal synapses, leading to changes in synaptic function and visual behavior, highlighting early retinal dysfunction in optic neuritis.

An in silico method has been used to discover N-hydroxy-substituted 2-aryl acetamide analogs as a new class of HIV-1 integrase inhibitors. Based on the molecular requirements of the binding pocket of catalytic active site, two molecules (compounds 2 and 4b) were designed as fragments. These were further synthesized and biologically evaluated.

Background: Development of new and effective therapeutics for sexually transmitted herpes simplex virus-2 (HSV-2) infection is important from public health perspective. With an aim to identify natural products from medicinal plants, in the present study, the potential of Terminalia chebula Retz was investigated for its activity against HSV-2.

Methods: Fruits of Terminalia chebula Retz were used to prepare 50% ethanolic extract.
