objective: anti-cyclic citrullinated peptide (anti-ccp) antibodies are highly specific markers for rheumatoid arthritis (ra) and useful for predicting rheumatoid arthritis (ra) development and progression. we assessed the diagnostic value of anti-ccp antibodies in our patients with ra. materials and methods: anti-ccp antibodies and rheumatoid factor (rf) titers were determined in 247 serum sam...

Two rabbits immunized with a portion of glutamate receptor (GluR) subunit GluR3 (amino acids 245-457) exhibited seizure-like behaviors, suggesting that antibodies to GluR3 may modulate neuronal excitability. Using whole-cell recording, rabbit GluR3 antisera were tested on cultured fetal mouse cortical neurons. In a subset of kainate-responsive neurons, miniperfusion of antisera and IgG evoked c...

  Background : Ulcerative colitis an inflammatory bowel disease (IBD) and chronically idiopathic immune related that associates with extraintestinal manifestations such as arthritis. Despite of the highly specificity ofanti-cyclic citrullinated peptide (CCP) antibodies for rheumatoid arthritis, their role in IBD remains unclear . There are only a few studies on the prevalence of anti-CCP antibo...

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that results from a progressive loss of motor neurons. Familial ALS (fALS) is caused by missense mutations in Cu, Zn-superoxide dismutase 1 (SOD1) that frequently result in the accumulation of mutant protein aggregates that are associated with impairments in the ubiquitin-proteasome system (UPS). UPS impairment has b...

OBJECTIVE Anti-AMPAR encephalitis is a recently discovered disorder characterized by the presence of antibodies in serum or cerebrospinal fluid against the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor. Here, we examine the antigenic specificity of anti-AMPAR antibodies, screen for new patients, and evaluate functional effects of antibody treatment of neurons. METHODS W...

SEE VAN DOORN AND JACOBS DOI101093/BRAIN/AWW078 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE  : In axonal forms of Guillain-Barré syndrome, anti-ganglioside antibodies bind gangliosides on nerve surfaces, thereby causing injury through complement activation and immune cell recruitment. Why some nerve regions are more vulnerable than others is unknown. One reason may be that neuronal membranes wi...
