take; In medical terminology, particularly pharmacology and immunology, -cept- derives from the Latin root for “take/seize,” used in drug names ending in -cept- to indicate receptor-binding fusion proteins or biologics engineered to capture/block specific molecular targets (e.g., cytokines, growth factors). These are typically monoclonal antibody-like-like therapies (e.g., etanercept) that “take” or neutralize inflammatory mediators by binding them, distinct from pure receptor agonists/antagonists; the convention follows FDA/ICH naming guidelines for biologics.
