Treg-associated oligomannose N-glycans trigger immune dysregulation in myasthenia gravis

Myasthenia gravis (MG) is an autoimmune neurological disease driven by the production of autoantibodies against components of the neuromuscular junction, resulting in fatigable muscle weakness, and in more severe cases, leading to life-threatening complications. This breakdown of immune tolerance has been associated with an impaired suppressive function and altered frequency of Regulatory T cells (Tregs) in autoimmune diseases, including MG. As key egulators of immune tolerance, Tregs play a...

Frozen in Place: Proximity Labeling Maps Glial Interactomes Across Cell States

Glial cells, including radial glia, oligodendrocyte precursor cells (OPCs), oligodendrocytes, astrocytes, and microglia, are active and dynamic regulators of central nervous system (CNS) development, homeostasis, and disease. Through extensive interactions with neurons, other glial populations, and the vasculature, they form highly specialized communication networks that are essential for normal brain function. While transcriptomic approaches have revealed extensive glial heterogeneity and en...

Communicating Genetic Information in Families with Inherited Late-Onset Neurodegenerative Diseases: A Scoping Review

Communicating genetic information within families living with inherited genetic conditions (IGCs), especially incurable and progressive late-onset neurodegenerative diseases (LONDs), presents significant challenges. To date, no literature review has specifically addressed this issue in families with LONDs. To fill this gap, a scoping review was conducted following PRISMA and JBI guidelines. Four databases (Scopus, Web of Science, PubMed, and PsycInfo) were searched, resulting in 31 articles f...

Activation of nuclear receptors correlates with tuberculosis severity and is a target for host-directed therapy

Introduction: The immune response to Mycobacterium tuberculosis is accompanied by metabolic adaptations that fuel host immunity, but that are exploited by the pathogen to ensure persistence and growth. Activation of nuclear receptors, such as liver-X-receptors (LXR), orchestrate macrophage immunometabolic adaptations to infection and globally associate with tuberculosis (TB) protection. Methods: We interrogated available transcriptomic datasets of whole blood from TB patients or M. tuberculos...
