Heparan sulfate may have a key role in tumor-spurred lymphatic vessel growth

Cancer has a mighty big bag of tricks that it uses to evade the body's natural defense mechanisms and proliferate. Among those tricks is one that allows tumor cells to turn the intricate and extensive system of lymphatic vessels into something of a highway to metastasis. Yet research unveiled this week may aid in the development of therapeutics that will put the brakes on such cancer spread, and the researchers who completed the study say the findings may extend to other lymphatic disorders.

Researchers discover molecular mechanisms behind autoimmunity

Researchers from Boston University School of Medicine have discovered that human proteins with an affinity for Dermatan Sulfate have the propensity to become autoantigens. In a companion article, the researchers also found that DS physically interacts with dead cells and that the resulting DS-autoantigen complexes drive autoreactive B-1a cell responses and autoantibody production both in-vitro and in mouse models.

Signaling pathway reveals mechanism for B cell differentiation in immune response

An article in Science Signaling by researchers at the RIKEN Research Center for Allergy and Immunology (RCAI) has clarified for the first time the mechanism governing differentiation of B cells into antibody-producing plasma cells. The finding establishes a role for the extracellular signal-regulated kinase (ERK) signaling pathway in B cell differentiation, a key step toward the development of B cell-targeted drugs for treatment of autoimmune diseases and allergies.

Research solves challenging problem of industry-scale production of large RNA molecules

Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress.

Researchers reveal how immune system distinguishes between beneficial and pathogenic organisms

The human gut is filled with 100 trillion symbiotic bacteria-ten times more microbial cells than our own cells-representing close to one thousand different species. "And yet, if you were to eat a piece of chicken with just a few Salmonella, your immune system would mount a potent inflammatory response," says Sarkis K. Mazmanian, assistant professor of biology at the California Institute of Technology (Caltech).
