Ontogenic evolution of chicken red cell Fc receptor
The ontogenic evolution of chicken red cell Fc receptor was studied in red cells from different age chicken embryos, baby chicken, and adult chicken. The Fc receptor binding capacity for ligands, the number of Fc receptors by red cell, and the association constant between receptor and ligand were an...

| description | The ontogenic evolution of chicken red cell Fc receptor was studied in red cells from different age chicken embryos, baby chicken, and adult chicken. The Fc receptor binding capacity for ligands, the number of Fc receptors by red cell, and the association constant between receptor and ligand were analyzed. The Fc receptor is expressed in the red cell surface of 6-day chicken embryo and its binding capacity for ligand—minimal at this moment—is increased in the 8-day chicken embryo red cells. The 12-day chicken embryo erythrocytes binding capacity is similar to the adult chicken red cells. The number of Fc receptors by red cell increase with the age of chicken embryo. After 9 days this number is not modified and it is the same as in adult chicken. Variations of Ko and binding capacity for ligands show a similar evolution in embryogenic development. From these data we suggest that although on Day 9 the number of receptors per cell is the same as in adult chicken, the receptors are not completely exposed at this time and as a consequence, their binding capacity for ligands is lower than in adult chicken erythrocytes. |
