5 different kinds of cytokine release assays: weathering the storm | CRA Post II

In our previous post, we outlined the dangers of Cytokine Release Syndrome (CRS) and the importance of preclinical Cytokine Release Assays (CRAs) when developing monoclonal antibodies (mAbs) that interact with the patient’s immune system. In this second post, we describe the different kinds of assays in use and how these …

In vitro cytokine release assays: is there calm after the storm? | CRA Post I

What is a cytokine storm?  Cytokine Release Syndrome (CRS), otherwise known as cytokine storm, is a systemic inflammatory response caused by complications due to disease, infection or an adverse effect of biologic therapy. The clinical symptoms of a cytokine storm are massive release of a potent cocktail of pro-inflammatory cytokines …

Understanding the Power of Natural Killer Cells and New Nonradioactive Assay Approaches

Natural killer (NK) cells first earned their title as “killers” nearly 40 years ago when researchers observed the rapid immune response of these lymphocytes as they destroyed host cells infected with a virus or tumor cells. It seemed that NK cells could attach spontaneously without prior activation. Over time, researchers …
