Mimicking a chronic immune response changes the brain
Abnormal production of Inflammatory cytokines by the immune system is responsible for a host of autoimmune disorders. One important cytokine is IL-17A, which is also involved in neurological diseases. Researchers at Tsukuba University in Japan made a mouse model of chronically high IL-17A and to study its effect on the brain. They show that it leads to reduced activity and density of microglia in the brain's hippocampus, but no obvious memory deficits. (2021-02-17)

Dennis tamed the protein from hell in seven years
A research group from Aarhus University has succeeded in understanding why a very extended structure is important for an essential protein from the human immune system. The new results offer new opportunities for adjusting the activity of the immune system both up and down. Stimulation is interesting in relation to cancer treatment, while inhibition of the immune system is used in treatment of autoimmune diseases. (2021-02-17)

Zika vaccine candidate shows promise in phase I trial
The Zika virus candidate, Ad26.ZIKV.001, a replication-incompetent human adenovirus serotype 26 (ad26) vector showed promising safety and immunogenicity in a phase I clinical trial. Researchers say the vaccine warrants further development should the need reemerge. The findings are published in Annals of Internal Medicine. (2021-02-15)

Gene variants increase risk of Addison's disease
Variants of nine genes increase the risk of developing Addison's disease, a rare disease in which the immune system attacks the adrenal glands. That is according to the largest genetic study to date on patients with Addison's disease. The findings help increase knowledge about what causes the disease. The study was conducted by researchers at Karolinska Institutet, Sweden, and Bergen University, Norway, and is published in the journal Nature Communications. (2021-02-11)

Substance in the blood of pregnant women fights pathological immune reaction
Scientists studied the effect of trophoblastic β1-glycoprotein in the blood of pregnant women on pro-inflammatory immune cells. Thanks to trophoblastic β1-glycoprotein, a woman's body does not adversely react to the fetus and supports its normal development until birth. It turned out that trophoblastic β1-glycoproteins also suppressed the development of pro-inflammatory lymphocytes and reduced their activity. (2021-02-10)

When hyperactive proteins trigger illnesses
Autoimmune diseases, in which the body's own immune system attacks healthy tissue, can be life-threatening and can impact all organs. A research team at the Technical University of Munich (TUM) has now found a possible cause for these self-destructive immune system attacks: a hyperactive RANK protein on the surface of B cells. The research opens the door to new therapeutic possibilities. (2021-02-02)

Childhood trauma could affect development, treatment of multiple sclerosis
Childhood trauma could affect the trajectory of multiple sclerosis development and response to treatment in adulthood, a new study in mice found. Mice that had experienced stress when young were more likely to develop the autoimmune disorder and less likely to respond to a common treatment, researchers at the University of Illinois Urbana-Champaign found. However, treatment that activated an immune-cell receptor mitigated the effects of childhood stress in the mice. (2021-01-29)

Scientists find key function of molecule in cells crucial for regulating immunity
UNC School of Medicine scientists led by Jenny Ting, PhD, the William Kenan Distinguished Professor of Genetics, and Yisong Wan, PhD, professor of microbiology and immunology, discovered that AIM2 is important for the proper function of regulatory T cells, or Treg cells, and plays a key role in mitigating autoimmune disease. Treg cells are a seminal population of adaptive immune cells that prevents an overzealous immune response, such as those that occurs in autoimmune diseases. (2021-01-28)

Study finds especially high rates of lupus in certain racial/ethnic groups
The US prevalence of the autoimmune disease lupus is 72.8 cases per 100,000 individuals, according to an analysis of population-based registries. The analysis, which is published in Arthritis & Rheumatology, found that the rate is 9 times higher for females than males (128.7 vs. 14.6 per 100,000), and it's highest among American Indians/Alaska Natives and Black females.

(2021-01-21)

Fatty acid may help combat multiple sclerosis
The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study. The finding suggests that dietary change might help treat some people with the autoimmune disease. (2021-01-19)

Scientists discover key enzyme responsible for skin blistering in the elderly
The Granzyme B (GzmB) enzyme, which accumulates in certain tissues as we age, has been identified as a driver of itchy and sometimes life-threatening autoimmune conditions known as pemphigoid diseases (PDs), which cause blistering and skin erosion below the skin's surface. New research led by University of British Columbia (UBC) and Vancouver Coastal Health Research Institute (VCHRI) scientists has found that a gel containing a specific and potent inhibitor of GzmB activity, VTI-1002, resulted in significant improvements on skin affected by PDs. (2021-01-12)

A subtle change in the DNA may predispose to polyneuropathy after gut infection
Researchers from Tokyo Medical and Dental University (TMDU) identified a novel genetic variant associated with Guillain-Barré syndrome (GBS). By analyzing the DNA sequence of patients with the disease, the researchers identified two novel variants of the ganglioside-binding protein Siglec-10 accumulated in the patients. They found that one of these variants impairs the function of the protein, predisposing carriers to the development of GBS. This study improves our understanding of the pathophysiology of GBS.

Autoimmune diseases: similar molecular signatures in target tissues
A study conducted by Professor Decio L. Eizirik's group - ULB Center for Diabetes Research - and published in Sciences Advances shows that autoimmune diseases, including type 1 diabetes, must be studied in their entirety, taking into account not only the immune system but also the target tissues. Indeed, the key mechanisms induced by inflammation, potentially shared between type 1 diabetes, systemic lupus erythematosus, multiple sclerosis and rheumatoid arthritis, could generate similar molecular signatures at the target tissue level.

Vaccination against tuberculosis can reduce the spread of COVID-19 and ease its course
St Petersburg University scientists have analysed about 100 academic papers and statistics on the incidence of COVID-19 in different countries of the world. Analysis of these data showed that the spread of the new coronavirus infection occurs more slowly where there is a large percentage of people vaccinated against tuberculosis with the BCG vaccine. Moreover, this vaccination itself, given in early childhood, changes the immune system in such a way that the new coronavirus disease course tends to be less severe. (2020-12-03)

Safe pregnancy is possible for women with interstitial lung disease
A new study shows that women with interstitial lung disease (ILD) related to autoimmune disease may not need to terminate their pregnancies--despite the increased risk of adverse outcomes--provided they have close monitoring from their team of multidisciplinary physicians before, during and after pregnancy. Results of the research was presented at ACR Convergence, the American College of Rheumatology's annual meeting. (2020-11-06)

A novel immunotherapy proves effective in animal models of multiple sclerosis

Unraveling the genetic determinants of small vessel vasculitis
Researchers from the University of Tsukuba have shown that the single-nucleotide variants of TERT and DSP, which promote risk for idiopathic pulmonary fibrosis (IPF), are significantly associated with susceptibility to microscopic polyangiitis and myeloperoxidase-ANCA associated vasculitis. Interestingly, there was no clear link to the severe complication interstitial lung disease (ILD). These findings suggest a shared genetic susceptibility between IPF and ANCA-associated vasculitides that may be independent of ILD risk. (2020-11-03)
