Autoimmunity: New immunoregulation and biomarker

autoimmunity

Clinicians at Ludwig-Maximilians-Universitaet (LMU) in Munich have elucidated a mechanism involved in determining the lifespan of antibody-producing cells, and identified a promising new biomarker for monitoring autoimmune diseases like multiple sclerosis and lupus erythematosus.

Researchers find genetic link between overactive and underactive immune systems

Girl getting sick

In the largest genetic study to date of a challenging immunodeficiency disorder, scientists have identified a gene that may be a “missing link” between overactive and underactive immune activity. The gene candidate also plays a key role in autoimmune diseases such as type 1 diabetes, rheumatoid arthritis and even allergies.

Not “just” crazy – Some psychoses caused by autoimmunity

schitzophrena

Antibodies defend the body against bacterial, viral, and other invaders. But sometimes the body makes antibodies that attack healthy cells. In these cases, autoimmune disorders develop. Immune abnormalities in patients with psychosis have been recognized for over a century, but it has been only relatively recently that scientists have identified specific immune mechanisms that seem to directly produce symptoms of psychosis, including hallucinations and delusions. In other words, some forms of psychoses might just be an autoimmune disorder.

New compounds protect nerves from the damage of MS

multiple sclerosis

Autoimmune diseases are tough to live with, frankly we don’t really understand the reasons they start at all, how to treat them, or even where to start in forming a cure. Well there might be some good news — as far as a treatment goes anyway — a newly characterized group of pharmacological compounds block both the inflammation and nerve cell damage seen in mouse models of multiple sclerosis.

Seafood associated with autoimmune disease

Autoimmunity is one of those great mysteries of the human body. We still aren’t sure what causes it and treating it can be painfully ineffective. Unfortunately my sister knows that one first hand, so here at the labs autoimmunity is a problem close to our heart. While we may not know what causes autoimmunity, a new study suggests one of the greatest risk factors for autoimmunity among women of childbearing age may be associated with exposure to mercury such as through seafood.

Stem cells derived from amniotic tissues have immunosuppressive properties

pregnant women

Stem cells derived from human amnion have for some time been considered promising for cell therapies because of their ease of access, ability to differentiate, and absence of ethical issues. Now, a research team has found that stem cells derived from human female amnion also have immunosuppressive activity and that the addition of antibodies to specific factors can enhance their immunosuppressive potential.

A New Discovery in the Treatment of Autoimmunity and Chronic Inflammation

cure

Lupus, Type 1 diabetes, and multiple sclerosis are all diseases brought on by autoimmunity — the bodies inability to tell itself apart from foreign invaders. Finding a cure, or even a suitable treatment has been to put it gently a long, painful road, with little to show for it. On the forefront of the war against the body betrayal is immunosuppressants, which with them carry their own set of side effects and in most cases only off mild to moderate relief of symptoms. But that is all changing and new research on something called immunoproteasomes offer that new hope.

Nanosponges Clean up Antibody-mediated Autoimmune Disease

autoimmune-arthritis-day

What does lupus, rheumatoid arthritis, type I diabetes, multiple sclerosis, and rheumatic heart disease have in common? All of these (and many other) apparently unrelated disorders are caused by autoimmunity, in which the immune system produces antibodies that attack normal, healthy cells and tissues. Currently considered incurable, these autoimmune diseases can be managed, but to varying degrees and not without serious side effects. Moreover, autoimmune diseases include a wide range of dysfunctional immune responses known as type II, type III, and type IV immune hypersensitivity reactions.
