T he CD28 antibody TGN1412, intended as a treatment for B cell chronic lymphocytic leukemia, caused systemic organ failure in initial human volunteers. This severe side effect was subsequently attributed to induction of a pro-inflammatory cytokine storm. Failure to detect this effect in animal studies underscores the need to supplement animal data with an evaluation of cytokine storm potential in human cells. We used human peripheral mononuclear cells (PBMCs) and monocyte-derived dendritic cells (DCs) to evaluate the cytokine storm potential of several siRNA compounds by measuring a panel of cytokines using Luminex. While some of the compounds elicited cytokines in PBMCs, the compounds failed to elicit cytokines in DCs. This finding demonstrates the value of an in vitro assay to evaluate potential immunostimulatory compounds and suggests that a robust evaluation may require examination of multiple cell types
