The chimpanzee (Pan troglodytes, Patr) is the closest zoological living relative of humans and shares approximately 98.6% genetic homology to human beigns. Although major histocompatibility complex (MHC) plays a critical role in T cell-mediated immune responses in vertebrates, the information on Patr MHC remains at a relatively poor level. Therefore, we attempted to isolate Patr MHC class II genes and determine their nucleotide sequences. The cDNAs encoding Patr MHC class II DP, DQ and DR β chains were isolated from the cDNA library of a chimpanzee B lymphocyte cell line Bch261. As a result of screening, the clone 6-3-1 as a representative of Patr DP clone, clone 30-1 as a Patr DQ clone, and clones 4-7-1 and 55-1 having different sequences as Patr DR clones were detected. The clone 6-3-1 consisted of 1, 062 nucleotides including an open reading frame (ORF) of 777 bp. In the same way, clone 30-1 consisted of 1, 172 nucleotides including ORF of 786 bp, clones 4-7-1 and 55-1 consisted of 1, 163 nucleotides including ORF of 801 bp. Except for five nucleotide changes, clones 4-7-1 and 55-1 were the same sequence. By comparison with the nucleotide sequences already reported on chimpanzee MHC class II β1 genes, clones 6-3-1, 30-1, 4-7-1 and 55-1 were classified as PatrDPB1<SUP>*</SUP>16, PatrDQB1<SUP>*</SUP>0302, PatrDRB1<SUP>*</SUP>0201 and PatrDRB1<SUP>*</SUP>0204, respectively. This is the first report to describe complete cDNA sequences of Patr DP and DQ molecules. The nucleotide sequence data of Patr MHC class II genes obtained in this study will be useful for the genotyping of Patr MHC class II genes in individual chimpanzees.
