Abstract
The major histocompatibility complex (MHC) includes highly polymorphic gene families encoding proteins crucial to the vertebrate acquired immune system. Classical MHC class I (MHCI) genes code for molecules expressed on the surfaces of most nucleated cells and are associated with defense against intracellular pathogens, such as viruses. These genes have been studied in a few wild bird species, but have not been studied in long-distance migrating shorebirds. Red Knots Calidris canutus are medium-sized, monogamous sandpipers with migratory routes that span the globe. Understanding how such long-distance migrants protect themselves from disease has gained new relevance since the emergence of avian-borne diseases, including intracellular pathogens recognized by MHCI molecules, such as avian influenza. In this study, we characterized MHCI genes in knots and found 36 alleles in eight individuals and evidence for six putatively functional and expressed MHCI genes in a single bird. We also found evidence for recombination and for positive selection at putative peptide binding sites in exons 2 and 3. These results suggest surprisingly high MHC diversity in knots, given their demographic history. This may be a result of selection from diverse pathogens encountered by shorebirds throughout their annual migrations.

Alignment of exon 1 (signal peptide), exon 4 (α3 domain) and exons 5 to 8 (transmembrane and cytoplasmic domains) in Red Knot and Red-billed Gull MHCI amino acid sequences with chicken and goose as outgroups (see Fig. 2 for exons 2 and 3). In exon 4, CD8 binding sites are shown by yellow annotations and intra- and inter-domain contacts by purple triangles. Sequence sources are Gaga (chicken, G. gallus BF2, AL023516), Anan (domestic goose, A. anser, MHC class I antigen gene, AY387655), Lasc (Red-billed Gull, L. scopulinus, UAA, HM008713, UBA, HM008714, UCA, HM008715, UDA, HM008716). Separate alignments for different exons show only alleles with coverage across the exon in question. The first residue of the signal peptide is alignment position 1 (the start codon M) (DOC 535 kb)
