MANHASSET, N.Y.--(BUSINESS WIRE)--New research, published March 16 in Nature Communications, shows how antibodies could benefit lupus patients with nervous system dysfunction.

Lupus, or systemic lupus erythematosus (SLE), is an autoimmune disease in which a person’s immune system attacks cells and organs through antibodies. This autoimmune attack on the body and its organs can cause rashes, arthritis, renal disease, anemia, and nervous system dysfunctions like spatial memory impairment. Anti-DNA antibodies are a hallmark of SLE.

Research conducted by scientists from the Feinstein Institutes for Medical Research and Stony Brook University in mice observed that an antibody found in patients that binds both DNA and a receptor on excitatory neurons in the brain will modulate the activation of the receptor. Their studies suggest that existing pharmacologic inhibitors of the receptor may improve the cognitive function of the mice. Feinstein Institutes researchers Betty Diamond, MD, Patricio Huerta, PhD, Bruce Volpe, MD, are co-authors on the paper.

“We were able to identify the specific receptors and interactions that lead to cognitive decline in patients living with lupus,” said Dr. Diamond, director of the Institute of Molecular Medicine at Feinstein. “This opens up new avenues of therapeutics to target the body’s immune system response and shut down harmful behavior.”

These studies were performed in a mouse model of neuropsychiatric SLE. Subsequent studies will address whether existing pharmacologic inhibitors of the receptor can improve cognitive function in this model. If so, it will be possible to consider clinical trials in patients.

“Dr. Diamond and her team are leaders in the cognitive and neurological problems of complex autoimmune disorders,” said Kevin J. Tracey, MD, president and CEO of the Feinstein Institutes. “These new findings are an important step in the pursuit of developing new experimental therapies for lupus.”

Feinstein Institutes’ Researchers Develop Promising Therapeutic for Sepsis-Induced Acute Lung Injury

MANHASSET, N.Y.--(BUSINESS WIRE)--Scientists at Northwell Health’s Feinstein Institutes for Medical Research are making strides in controlling the severe inflammation that is the hallmark of sepsis. This severe condition occurs when the body’s immune system reaction to infection causes it to attack its own tissues and organs, often resulting in organ failure or death. Researchers have uncovered a critical mechanism driving acute lung injury (ALI) in sepsis, identifying a novel subset of neutrop...
