  AtaGenix MOG–Enabled Study Reveals Meningeal B Cells Drive MS Relapse via MHC II–GM-CSF Loop

  Leveraging high-purity recombinant MOG protein provided by AtaGenix, this study shows that brain-border autoreactive B cells initiate and amplify CNS autoimmunity in EAE. Intracisterna magna delivery selectively manipulated leptomeningeal B cells, revealing MHC II–dependent cognate interactions with encephalitogenic T cells that boost GM-CSF, recruit neutrophils, and activate endothelium before symptoms. These events form a local inflammatory loop that accelerates onset. Selective depletion of brain-localized B cells attenuated relapse without systemic B-cell ablation, establishing meningeal autoreactive B cells as key initiators of neuroinflammation and tractable therapeutic targets in relapsing multiple sclerosis.

  Rational Design of Patatin Lipase: AtaGenix-Supported Expression Enables Enhanced Long-Chain Specificity

  Patatin is a potato glycoprotein with emulsifying and antioxidant properties but limited by low expression and short-chain bias. With AtaGenix support, recombinant Patatin was expressed in Pichia pastoris (121 mg/L). The D286A mutant showed 3.2-fold higher long-chain activity, improved stability (+5.4 °C), and preserved structure. This AtaGenix-enabled work offers a scalable platform for Patatin engineering with applications in functional lipids, food biotechnology, and green biocatalysis.

  Insect Cell/Baculovirus Protein Expression Services – Providing Efficient and Reliable Research Support

  AtaGenix, a leader in biotechnology, has pioneered the development of the ENO1 monoclonal antibody (ENO1mAb) using advanced hybridoma technology to target α-enolase (ENO1), a key enzyme in cervical cancer progression. Expressed in insect cells and delivered via proprietary folic acid-conjugated PLGA nanoparticles, ENO1mAb effectively inhibits tumor invasion, proliferation, and clone formation by blocking ENO1's glycolytic and plasminogen activation roles. In vitro studies demonstrate significant reductions in lactic acid and pyruvate levels, showcasing AtaGenix's innovative approach to transforming cervical cancer treatment.
