Identification of immune-based biomarkers associated with response to abatacept (CTLA4-Ig) in rheumatoid arthritis patients.


ABSTRACT: RA patients (according to ACR/EULAR 2010 criteria) who started abatacept due to high disease activity (DAS28>5.1), were recruited to perform immunological studies at baseline, 3 and 6 months of therapy. Peripheral blood mononuclear cells (PBMCs) were isolated and immune cell populations were characterized using flow cytometry. Proteomic analysis was performed on baseline sera.

Abatacept (CTLA4-Ig)-a monoclonal antibody which restricts T cell activation-is an effective treatment for rheumatoid arthritis (RA). Nevertheless, only 50% of RA patients attain clinical responses, while predictors of response are rather limited. Herein, we aimed to investigate for early biomarkers of response to abatacept, based on a detailed immunological profiling of peripheral blood (PB) cells and serum proteins. We applied flow cytometry and proteomics analysis on PB immune cells and serum  ...[more]
