Study identifies new pathway to suppressing autoimmunity

Researchers at Stanford University School of Medicine, Yale University School of Medicine, and the Hospital for Special Surgery Research Institute have uncovered new details about how the immune system prevents the production of antibodies that can recognize and damage the body’s own, healthy tissues. The study, to be published September 29 in the Journal of Experimental Medicine (JEM), also reveals how this process is impaired in autoimmune disorders such as systemic sclerosis and systemic lupus erythematosus and suggests potential new strategies to treat these diseases.

COVID-19 and Type 1 Diabetes: Researchers Find an Increase in Islet Autoimmunity in Young Children Who Had a Sars-CoV-2 Infection

Type 1 diabetes is an autoimmune disease leading to an impaired glucose metabolism and requires life-long administration of insulin. While the cause of the autoimmunity reaction is still unclear, viral infections in young children are proposed to be critical environmental factors leading to type 1 diabetes.

‘Tipping The Balance’ Of Immune Cells from Bad to Good Reverses Multiple Sclerosis Symptoms in Mice

According to the federal government’s National Institute of Neurological Disorders and Stroke, nearly 3 million people worldwide — with almost a third in the United States — are living with multiple sclerosis (MS), a disabling neurological disease in which the body’s immune system mistakenly attacks nerves feeding information to the central nervous system (the brain and spinal cord). Although rarely fatal, MS can lead to long-term disabilities, and impair movement, muscle control, vision and cognition.

CHOP-led Study Identifies Two Different Regulatory T Cell Populations

A regulatory class of human T cells descends from two different origins, one that relates to autoimmunity and one that relates to protective immunity, according to a new study led by Children’s Hospital of Philadelphia (CHOP). The findings, published today in Science Immunology, could pave the way for new treatments for autoimmune diseases that target the immune system selectively.

New $17 million grant establishes LJI as global hub for immunology data curation and analysis

A new grant of over $17 million from the National Institute of Allergy and Infectious Diseases (NIAID) has established La Jolla Institute for Immunology (LJI) as the leading institute for human immunology data curation, analysis, and dissemination. With this funding, LJI has taken the helm of the Human Immunology Project Consortium Data Coordinating Center, a critical tool in the effort to fuel scientific collaboration in immunoprofiling and highlight findings from the overall Human Immunology Project Consortium (HIPC).

Type 1 diabetes: Tannic acid encapsulation protects transplanted islets from rejection

Transplanting cadaver pancreatic islets is a promising therapy for Type 1 diabetes, but a reactivated autoimmunity means low graft viability after five years. Research now shows that a protective coating of two biopolymers can delay allograft and autoimmune-mediated rejection in mouse models of T1D.

Protein that Keeps Immune System from Freaking Out Could Form Basis for New Therapeutics

Treatment with a peptide that mimics the naturally occurring protein GIV prevents immune overreaction and supports a mechanism critical for survival in mouse models of sepsis and colitis, according to a UC San Diego study.
