    Looks like an interesting new type of treatment for autoimmune diseases
    They have published a paper just out in Nature Biotechnology. Although the full paper is not freely available.

    "The nanoparticles have already been approved by the Food and Drug Administration in the US for a different use and could be easily manufactured making the treatment cheaper than other approaches."

    Nanoparticle approaches are interesting ... but potentially very unpredictable. Essentially this is about confusing the immune system by modifying epitopes. The problem is those epitopes are usually functional ... they do something. So this can have the effect of a systemic poison. Its very dangerous, but at the same time very promising. One of the problems is that, as a biochemist, I have a poor understanding of nanoparticle physics. Properties of matter at that level are very different from what we are used to. So many people may find it hard to assess risk ... that includes both over-estimating and under-estimating risk. I think its worth researching, but its something that needs to be examined and tested very very thoroughly. Bye, Alex

    My hope is that as they look at the immune system from a different angle they may get some different insights. I suspect any treatments will be many years away. When I looked at there web site I did find this quote talking of natural nanoparticles (and synthesizing particles that mimic them. It made me wonder if there are many such particles in the body and what we understand about them.

    Researchers trying to find a way to treat multiple sclerosis think they’ve come up with an approach that could not only help patients with MS, but those with a range of so-called autoimmune diseases, from type-1 diabetes[​IMG] to psoriasis, and perhaps even food allergies.
    So far it’s only worked in mice, but it has worked especially well. And while mice are different from humans in many ways, their immune systems are quite similar.
    “If this works, it is going to be absolutely fantastic,” said Bill Heetderks, who directs outside research at the National Institute of Biomedical Imaging and Bioengineering, part of the National Institutes of Health, which helped pay for the research. “Even if it doesn’t work, it’s going to be another step down the road.”

    The pieces of this puzzle start coming together.

    A few quotes from the full study:

    "...We previously reported that intravenous administration of soluble peptides crosslinked to syngeneic splenic leukocytes using ethylene carbodiimide (ECDI) safely and efficiently induces antigen-specific immune tolerance, is effective in the prevention and treatment of T helper type 1 (TH1) cell– and/or TH17 cell–mediated autoimmune diseases and overcomes many of the drawbacks of the failed trials involving monoclonal antibodies and soluble peptides10–12...However, the challenge of isolating isologous leukocytes and peptide coupling under good manufacturing practices (GMP) may inhibit clinical application of this therapy...This study supports the use of antigen-coupled microparticles as a tool for tolerance induction. This option will probably have broad therapeutic utility, with preliminary studies in airway allergy27 and allotolerance18,28 yielding promising results..."

    We are moving forward.
