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 …

An Analytical Approach to Enhance Recruitment of Rheumatoid Arthritis Patients

No single blood test or physical finding alone can confirm the diagnosis of rheumatoid arthritis (RA). However, two tests that detect markers of inflammation are often ordered when RA is suspected: erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Other common tests include rheumatoid factor and anti-CCP antibodies. While the …

ELISPOT Assay: A Powerful Tool in Vaccine Development and Immune Monitoring

Over the past several years, the scientific community has made tremendous progress in advancing our understanding of the immune system, from the basic functions of its various components to molecular pathways that operate within those components. With new, state-of-the-art tools and technologies, immunologists now have the ability to better understand the …
