The chicken MHC (B complex) comprises L, F, and G regions, influencing immune responses and disease susceptibility. Its structure and function show similarities and differences compared to mammalian MHCs.

Area of Science:

Immunogenetics
Comparative Immunology
Avian Biology

Background:

The chicken Major Histocompatibility Complex (MHC), known as the B complex, was initially identified by controlling blood antigens.
It is now understood to consist of at least three distinct regions: L, F, and G.

Purpose of the Study:

To delineate the regions and functions of the chicken MHC (B complex).
To compare the chicken MHC with mammalian MHCs.

Main Methods:

Analysis of over 10,000 chickens to identify recombinants.
Biochemical, tissue distribution, and functional analyses.
Serological studies.

Main Results:

The F region corresponds to murine H-2 K/D regions.

The G region is unique to chickens, with products expressed on erythrocytes.

The L region corresponds to the H-2 I region, influencing immune responsiveness and expressed on lymphocytes and monocytes.

Conclusions:

The chicken MHC shares functional similarities with mammalian MHCs, including regulation of immune responses and disease resistance.
The chicken MHC differs from mammalian counterparts with lower crossing-over frequency and no apparent gene duplication.
