Recently we reported that a chimeric molecule containing mouse transferrin receptor and immunoglobulin G1 (IgG1) Fc, mTR-Fc, induced higher immune responses and can be used as a vaccine adjuvant. In this study, the immunological property of the molecule was investigated. Although, the mTR-Fc did not activate complement classical pathway, it was recognized by activated macrophage as like intact IgG Fc, which is recognized by macrophage via Fcgamma receptor. In addition, we found that splenocyte simultaneously exposed to lipopolysaccaride (LPS) and mTR-Fc produced higher amount of interleukin-10, comparing to that exposed to only LPS. These results suggest that the mTR-Fc molecules conserved the IgG Fc property to biasing immune responses via modulation of cytokine production by antigen presenting cell.

Antibody Structure

Overview
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.

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
