Biological advances and clinical applications of Fc receptors for IgG
1Children's Hospital of Philadelphia, Pennsylvania, USA.
There are three classes of Fc gamma receptor proteins, Fc gamma RI (CD64), Fc gamma RII (CDw32), and Fc gamma RIII (CD16), which are encoded by at least eight genes. In this review we summarize some of the biological advances in the Fc gamma receptors during the past year, specifically: 1) identification of genes and their products; 2) regulation of gene expression and modulation of receptor number; 3) cellular functions and mechanisms of signal transduction; 4) ligand binding and the role of polymorphisms; and 5) soluble Fc gamma receptors. We also highlight the direct clinical applications of this Fc gamma receptor research.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
