The main four groups of antigens were first discovered roughly 120 years ago. Now, there are currently 45 recognized blood group systems, which roughly has 362 red blood cell antigens in the mix.

The researchers note that red blood cells also host many more antigens, some of which cannot be categorized easily but still play an important role in human health.

The team found changes in the gene coding for the protein Piezo1 which would cause an altered protein on the surfaces of red blood cells in these individuals. By using gene editing on a cell line ...

SQZ TACs are a red blood cell ... The presentation includes novel preclinical data highlighting SQZ TACs and the reduction of antigen-specific CD4 and CD8 T cell activity and increase antigen ...

The cryopreservation of red blood cells (RBCs) holds great potential for ensuring timely blood transfusions and maintaining an adequate RBC inventory. Cryoprotectants (CPAs) are a series of ...

Blood usually falls into a few widely recognized categories or types, based on the proteins that are expressed on the surface of red blood cells. For example, A or B antigens may be present there, ...

The A antigens can be extended to yield galactose (Gal)-A and H type 3 structures. Additional extension of H type 3 yields A type 3 antigen. Besides, an extended B antigen (ExtB) was reported in 2019.
