French researchers have developed nanobodies that can attach to vascular cell adhesion molecule-1, which is linked to the development of atherosclerosis, according to a study published in Circulation Research. The nanobodies can be tagged with technetium-99m and imaged through SPECT, according to the study. Researchers said SPECT also identified human and mouse cross-reactive labeled VCAM-1, indicating that the nanobodies can be used in the clinical setting.
