Researchers from The University of Osaka have discovered a new class of antibodies, called iTabs, that naturally suppress specific immune responses by blocking immune cell activation. These antibodies can reduce autoimmune disease severity in mice, suggesting a new way to treat conditions like multiple sclerosis without weakening the immune system overall.Researchers from The University of Osaka have discovered a new class of antibodies, called iTabs, that naturally suppress specific immune responses by blocking immune cell activation.
