Pharmacological Management of IgG4-Related Disease: From Traditional to Mechanism-Based Targeted Therapies.

Drugs Aging

January 2025

Division of Rheumatology, Department of Internal Medicine, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo, 160-8582, Japan.

IgG4-related disease (IgG4-RD) is an immune-mediated disorder characterized by organ enlargement and dysfunction. The formation of tertiary lymphoid tissues (TLTs) in affected organs is crucial for understanding IgG4-RD, as T follicular helper (Tfh) 2 cells within TLTs drive IgG4+B cell differentiation, contributing to mass formation. Key cytokines IL-4 and IL-10, produced by Tfh2 cells, are essential for this process.

Ferguson Plot Analysis of Chaperone ClpB from Moderate Halophile.

Protein J

January 2025

Alliance Protein Laboratories, 13380 Pantera Road, San Diego, CA, 92130, USA.

The Ferguson plot is a simple method for determining the molecular weight of native proteins and their complexes. In this study, we tested the validity of the Ferguson plot based on agarose native gel electrophoresis using multimeric chaperone protein, ClpB, derived from a moderate halophile that forms a native hexamer. The Ferguson plot showed a single band with a molecular weight of 1,500 kDa, approximately twice the size of the native hexamer.

Epilepsy is a serious neurological disease that impacts all facets of a patient's life, including their socioeconomic situation. The failure to identify underlying epileptic signatures in their early stages might result in severe harm to the central nervous system (CNS) and permanent adverse changes to some organs. Therefore, numerous antiepileptic drugs (AEDs are frequently used to control and treat the frequency of seizures.

Migrasome formation is initiated preferentially in tubular junctions by membrane tension.

Biophys J

January 2025

Department of Physiology and Pharmacology, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel; Center for Physics and Chemistry of Living Systems, Tel Aviv University, Tel Aviv, Israel. Electronic address:

Migrasomes, the vesicle-like membrane micro-structures, arise on the retraction fibers (RFs), the branched nano-tubules pulled out of cell plasma membranes during cell migration and shaped by membrane tension. Migrasomes form in two steps: a local RF bulging is followed by a protein-dependent stabilization of the emerging spherical bulge. Here we addressed theoretically and experimentally the previously unexplored mechanism of bulging of membrane tubular systems.

Enhanced Genome Editing Activity with Novel Chimeric ScCas9 Variants in Rice.

Adv Sci (Weinh)

January 2025

Research Institute of Big Data Science and Industry, Shanxi University, Taiyuan, Shanxi, 030006, China.

The Streptococcus canis Cas9 protein (ScCas9) recognizes the NNG protospacer adjacent motif (PAM), offering a wider range of targets than that offered by the commonly used S. pyogenes Cas9 protein (SpCas9). However, both ScCas9 and its evolved Sc++ variant still exhibit low genome editing efficiency in plants, particularly at the less preferred NTG and NCG PAM targets.
