The social relevance of philosophy
What is the social relevance of philosophy? Any answer to this question must involve at least three elements. First, we need to understand how philosophy has brought about social change in the past. Second, to dig into the question more deeply, we need to see how the definition of philosophy can be opened up. Thirdly, we need to critically examine and challenge some of the assumptions that might be hidden in the question. Once we have done all this, we can try to answer the question
Shared and divergent sequences in related CEHs.
<p>A) A region of nearly identical sequence for the B8,DR3 and B18,DR3 CEHs was previously reported <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen.1004637-Traherne1" target="_blank">[19]</a> and is represented by the broken line rectangle, and ends just centromeric to <i>MTC30P1</i>, approximately 50 kb centromeric to <i>HLA-DQB1</i><a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen.1004637-Stewart1" target="_blank">[18]</a>. B) Shared sequence for the B7,DR15 and B18,DR15 CEHs is shown in the broken line rectangle. Sequence identity for these two CEHs ends centromerically between introns 8 and 6 of <i>TAP2</i>. C) Shared and divergent sequences for four DR4,DQ8 CEHs are shown in the broken line rectangle. <i>HLA-B*15:01</i> and <i>HLA-B*40:01</i> are alleles of the B62 and B60 specificities, respectively.</p

MHP cell line and CEH allele-level typing in the core MHC region and <i>HLA-DPB1</i>.
<p>Shown are MHC alleles for the eight MHP cell lines and, underneath each, for the population CEH(s) that share HLA-DR-DQ specificities with them. Although a known CEH shares HLA-DR-DQ specificities with APD, that CEH does not share significant class II sequence similarity to APD, and is not displayed. Genes are in chromosomal order from telomere to centromere, except <i>CFB</i> and <i>C2</i> are switched because complotype was historically defined in the order shown. HLA gene alleles are shown at the highest definition known up to 4-digit resolution. Alleles containing â/â indicate microvariation.</p>a<p>Abbreviations: UNK â=â Unknown (insufficient data).</p>b<p>This CEH has two possible <i>HLA-C</i> alleles: <i>*04:01</i> and <i>*04:09N</i><a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen.1004637-Romero1" target="_blank">[14]</a>, <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen.1004637-Pinto1" target="_blank">[16]</a>.</p><p>MHP cell line and CEH allele-level typing in the core MHC region and <i>HLA-DPB1</i>.</p
Measures of genetic diversity at the allele level for HLA system in a Mexican admixed population.
<p>O.H.: Observed heterozygosity. E.H.: Expected Heterozygosity. <i>p</i> values <0.05 are considered statistically significative and thus reflect differences between O.H. and E.H. PIC: Polymorphism Information Contents. PD: Power of Discrimination.</p
Frequencies of <i>HLA-DRB1-DQB1</i> blocks in 234 Mexican admixed individuals (468 haplotypes).
<p>Blocks of each ancestry (Amerindian, Caucasian, Caucasian shared with other populations, African and Asian) were defined as those found in original populations with H.F. >1,0%, and not found in other native human groups in frequencies higher than 1,0%. We consider <i>t</i> value must be â„2.0 to denote statistically significant association and thus validate ÎâČ (shaded values).<sup>â </sup> Similar to DQB1*05â¶02 with a silent mutation at codon 133 cgg>cga.</p
CEH sequence fixity and crossover frequencies from <i>HLA-DQA2</i> to <i>DAXX</i>.
<p>Chromosomal location is shown to scale on the abscissa and starts at the mid-point between <i>HLA-DRB1 and HLA-DQB1</i> (AâC) or at <i>HLA-DQB1</i> (DâO). The locations of several HLA class II and extended class II genes are marked by arrows below Figures 3AâC and 3O. The 11 regions analyzed for normalized crossover frequency (NCF) are enumerated in Figure 3D. The numbers of haplotypes analyzed for each CEH are given in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen-1004637-t001" target="_blank">Table 1</a>. Sequence fixities (A) and NCFs (DâF) are shown for the CEHs B7,DR15 (black open circles), (D); B8,DR3 (green closed circles), (E); and B18,DR3 (red squares), (F). Sequence fixities (B) and NCFs (GâJ) are shown for the CEHs C4,B44,DR7 (green closed circles), (G); C16,B44,DR7 (purple open circles), (H); B57,DR7 (red squares), (I); and B44,DR4,DQ7 (blue diamonds), (J). Asterisks (*) in Figures 3B, 3G and 3H indicate that sequence fixities and NCFs could not be determined centromeric to the last data points for the two B44,DR7 CEHs. Sequence fixities (C) and NCFs (KâO) for various DR4,DQ8 CEHs are shown. These include the CEHs B44,SC30/SC31 (black diamonds), (K); B62,SC33 (green closed circles), (L); B38,SC21 (purple open circles), (M); B60,SC31 (red squares), (N); and B62,SB42 (blue triangles), (O). NCFs are normalized to the remaining conserved sequences and to 1 Mb relative to the distance over which crossovers were observed, and values are displayed for 11 sub-regions (<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004637#pgen.1004637.s005" target="_blank">Table S2</a>).</p
A map of the MHC class II and extended class II regions of chromosome 6p21.
<p>Sequenced sub-regions are marked by colored blocks (top). Distances (kb) are to scale from the human reference sequence. Gene locations from <i>HLA-DRA</i> on the telomeric (T) end to <i>DAXX</i> on the centromeric (C) end are shown.</p
