There are multiple neurotransmitters and neuromodulator systems mediating memory formation among which the endocannabinoid system plays a critical role in the memory formation by modulating the release of many neurotransmitters. Nucleus accumbens appears to have a site in the central of neuronal circuits of the limbic system and to be responsible for the integration and consolidation of inputs ...
Background and Objective: It has been shown that cannabinoids exert widespread effects on cognitive functions. An overlapping distribution of GABA with cannabinoid receptors has been reported in some brain structures such as dorsal hippocampus. Thus, the functional interactions between cannabinoid and GABAergic systems in cognitive control seem possible. The present study evaluated the potentia...
OBJECTIVE Early recognition and treatment of RA is associated with an improved outcome. The 2010 ACR/EULAR criteria for RA identify RA patients earlier than the 1987 ACR criteria. Nevertheless, we recently observed that 24% of the 2010 unclassified arthritis (UA) patients develop RA during follow-up. Here we studied this frequency in other cohorts and evaluated the prognostic accuracy of ACPA a...
INTRODUCTION Rheumatoid arthritis (RA) is associated with hypogalactosylation of immunoglobulin G (IgG). We examined whether a proxy measure for galactosylation of IgG N-glycans could predict response to therapy or was differentially affected by methotrexate (MTX) or TNF blockade. METHODS Using a previously defined normal phase high-performance liquid chromatography approach, we ascertained t...
BACKGROUND Anti-citrullinated-peptide antibodies (ACPA) have been detected in individuals with developing rheumatoid arthritis (RA) before the onset of symptom, with an initially limited spectrum of reactivities that gradually broadens. The aim was to analyze the evolution of ACPA response pre-dating symptom onset, using four selected citrullinated exogenous and endogenous antigens. METHODS A...
We studied the diagnostic performance of the anti-human citrullinated fibrinogen antibody (AhFibA) ELISA for rheumatoid arthritis (RA) in a consecutive cohort (population 1) and evaluated the agreement between the AhFibA ELISA and four other assays for anti-citrullinated protein/peptide antibodies (ACPAs) as well as rheumatoid factor in patients with longstanding RA (population 2). Population 1...
BACKGROUND Autoreactive B cells are crucial players in the pathogenesis of rheumatoid arthritis (RA). Autoantibodies specific for citrullinated proteins (ACPA), present in the serum of approximately 60-70 % of patients, have a pathogenic role in the disease. B cell depleting therapies may result in a transient immunosuppression, increasing the risk of infections. Our aim was to develop a new th...
