Abstract

Nanotechnology has has been giving birth to a variety of therapeutic and diagnostic products, referred to as nanomedicines (NM), whose successes are based on improved efficacy and/or diminished toxicity. However, these benefits are not without a price. The introduction into the clinics of many NM revealed the presence of an acute immune response to the particles, manifested in hypersensitivity reactions (HSR). The phenomenon is often due to the structural similarity of reactogenic NM to viruses, which may trigger the nonspecific arm of humoral immunity, the complement (C) system to an immediate eliminatory response. The clinical manifestations of this reaction, called C activation-related pseudoallergy (CARPA), include cardiopulmonary distress, which is a safety risk for NM, particularly in the case of cardiac patients with atopic constitution. Thus, understanding CARPA and ways of its prediction and prevention represents an important challenge in NM R&D.
