Class II molecules encoded by the human major histocompatibility complex (MHC) are involved in regulating T-cell response to antigens1–3. The mechanisms for generating polymorphism in products of the MHC have been studied extensively for both the murine H–2 and the human HLA complex. Such studies indicate that point mutations plus selection have a major role in the generation of polymorphisms of class I and class II MHC genes4–8. However, a non-reciprocal gene conversion mechanism has been… Expand

Molecular and Genetic Mechanisms Involved in the Generation of Mhc Diversity
• Biology
• 1991
The sequence data for Ab, together with other data, suggest that various molecular and genetic mechanisms are involved in the generation of Mhc diversity, particularly within exon 2, where a sequence highly homologous to a minisatellite common core sequence has been identified. Expand
Concerted evolution in a segment of the first domain exon of polymorphic MHC class II β loci
• Biology, Medicine
• Immunogenetics
• 2004
The observed similarity in the α-helical region of class II β molecules may be functionally significant for the utilization of the T-cell repertoire for antigen recognition in the immune system. Expand
Allelic diversity at class II DRB1 and DQB loci of the pig MHC (SLA)
• Biology, Medicine
• Immunogenetics
• 1999
Analysis of clustered sequence variation suggested intra-exon gene conversions in which the χ-like sequences act as putative breakpoints must be an important mechanism in the generation of allelic polymorphism at the SLA-DRB1 andSLA-DQB. Expand
Generation of MHC Class II Diversity by Intra‐ and Intergenic Recombination
• Biology, Medicine
• Immunological reviews
• 1995
Evidence that intragenic recombination has contributed to the generation of allelic diversity at a DRB locus in the moose was presented, implying that exchange of sequence information has occurred repeatedly during the course of evolution. Expand
Birth of a new allele in a sibling: cis or trans gene conversion during meiosis?
• Biology, Medicine
• Immunogenetics
• 1997
The immune response in higher vertebrates is a complex phenomenon mediated by a network of cellular interactions, and major histocompatibility complex (MHC) class II DR, DQ, and DP molecules play a central role in immunity by binding and presenting peptides to helper T lymphocytes. Expand
Structure and organization of pigMHC class IIDRB genes: evidence for genetic exchange between loci
• Biology, Medicine
• Immunogenetics
• 2007
The pig major histocompatibility complexDRB genes were studied by polymerase chain reaction (PCR) amplification of exon 2 from eight domestic pigs and two European wild boars, showing sequence similarities that indicate that the sequences have been exchanged between theDRBs by intergenic recombination.

The evolutionary origin of the major histocompatibility complex: Polymorphism of class II α chain genes in the cartilaginous fish
• Biology, Medicine
• European journal of immunology
• 1993
The MHC‐peptide‐based T cell recognition system appears to have arisen at or before the emergence of the cartilaginous fish, and the Gici‐DAA and Gici-DBA genes display a polymorphism pattern essentially similar to that of mammalian MHC genes playing a major role in Ag presentation. Expand
Evolution of MHC Class II Allelic Diversity
The class I and class II molecules of the major histocompatibility complex are cell surface heterodimeric proteins whose primary function is the presentation of self and foreign antigens to T cells.Expand
The molecular basis of HLA-disease association.
• Biology, Medicine
• 1989
The human major histocompatibility complex (MHC) has been the object of more extensive characterization than any other polymorphic system in man, and certain MHC alleles were strongly associated with susceptibility to over 40 diseases, mostly autoimmune in nature. Expand
Nucleotide sequence of a novelHLA-DR4B1 allele,DRBI *0409
• Biology
• Immunogenetics
• 2005
While screening a population of rheumatoid arthritis patients with oligonucleotide probes specific for HLA-DR4-associated sequences, an unusual reaction pattern was defined in one individual and cloning and sequencing of most of the second exon of the H LA-DR 4B1 gene from this individual demonstrated a new DR4B1 allele, Hla-DRB1 *0409.
