Different JAKinibs modulated distinct cytokine pathways to varying degrees, and no agent potently or continuously inhibited an individual cytokine signalling pathway throughout the dosing interval. This study aimed to compare the in vitro cellular pharmacology of BARI, TOF and UPA across relevant leukocyte subpopulations, coupled with their in vivo PK, to determine their effects on distinct cytokine pathways. Peripheral blood mononuclear cells from healthy donors were incubated with differen...

An evaluation of risk factors for major adverse cardiovascular events during tocilizumab therapy

Rao VU, Pavlov A, Klearman M, Musselman D, Giles JT, Bathon JM, Sattar N, Lee JS.
Arthritis Rheumatol. 2015;67(2):372–380

The risk of cardiovascular (CV) disease among RA patients, compared with the general population is well documented. Alongside this, studies have been able to establish that risk factors in RA patients are not wholly associated with traditional CV risk factors such as such as diabetes mellitus, hypertension, smoking, and dyslipidemia, suggesting a relationship between parameters of RA disease activity and increased CV risk. Additionally, IL-6 has been linked with the development of coronary heart...

JAK2-STAT3 Blockade by AG490 Suppresses Autoimmune Arthritis in Mice via Reciprocal Regulation of Regulatory T cells and Th17 cells

Park JS, Lee J, Lim MA et al.
J Immunol 2014; 192:4417-4424

In this study, Park et al sought to investigate the effects of the JAK2 inhibitor, AG490 in RA. Using murine CIA models, both preventative and therapeutic models were investigated. In the preventative model, CIA mice treated with AG490 showed a significantly lower incidence rate of arthritis and arthritic scores when compared to mice injected with vehicle. In the therapeutic model, as in the preventative, AG490 treated mice exhibited less severe arthritis. Through further experiments, it was de...
