Researchers discover how the NMDAR protein performs a 'Twist'-like dance move

Proteins are constantly performing a kind of dance. They move and contort their bodies to fulfill specific functions inside our bodies. The NMDAR protein executes an especially hard dance routine in our brains.

Clinical Guideline on Evaluation and Treatment for Autoimmune Encephalitis

#AntiNMDAR Encephalitis Clinical Practice Guideline
Improving Time to Diagnosis, Treatment, and Hospital Length of Stay

β€œA clinical practice guideline (CPG) was created to standardize evaluation and treatment for patients with suspected anti-methyl-d-aspartate receptor (#NMDAR) #autoimmuneencephalitis (AE), the most common AE in children. The objective of this study was to evaluate the CPG effect on time to #diagnosis, #treatment, and hospital length of stay (LOS).”

"In a passive transfer mouse model, NMDAR-CAAR T cells led to depletion of an anti-NMDAR B cell line and sustained reduction of autoantibody levels without notable off-target toxicity. Treatment of patients may reduce side effects, prevent relapses, and improve long-term prognosis. Our preclinical work paves the way for CAAR T cell phase I/II trials in #NMDAR #encephalitis and further autoantibody-mediated diseases."
