Hemoglobin carrying oxygen
Web10 apr. 2024 · Fetal hemoglobin carries oxygen more efficiently than adult hemoglobin, which is defective in SCD and TDT. Exa-cel is currently undergoing two Phase III trials, CLIMB-111 and CLIMB-121, as well as an ongoing long-term follow-up study, CLIMB-131. WebCells with sickle cell hemoglobin are stiff and sticky. When they lose their oxygen, they form into the shape of a sickle or crescent, like the letter C. These cells stick together and can’t easily move through the blood vessels. This can block small blood vessels and the movement of healthy, normal oxygen-carrying blood.
