Play is widespread across mammalian taxa, but species strongly vary in the ways they play. In less despotic primate species (i.e., with less steep dominance hierarchies, less severe conflicts, and more reconciliation), play has been described as being more frequent, cooperative, and freely expressed. To study the link between social play and dominance style, we compared play behavior in free-ranging infants, juveniles and subadults of more despotic Japanese macaques (Macaca fuscata, N = 24) and less despotic moor macaques (Macaca maura, N = 17). We found interspecific differences in play behavior that corresponded with the contrasting dominance styles of the study species, largely confirming our predictions. In particular, moor macaques spent a larger proportion of time in solitary and social play than Japanese macaques, while Japanese macaques spent a larger proportion of time in grooming interactions. In moor macaques, play sessions included more players, a larger variety of play behaviors, greater play face rates, a greater proportion of time in contact play, and a higher rate of reciprocal play-biting than in Japanese macaques. Aggressive escalations were not common, but more frequent in Japanese macaques. Finally, a higher frequency of play faces during play sessions predicted the occurrence of more reciprocal play-bites, but not the proportion of time spent in contact play behaviors. Additional studies on other groups and species will allow a better understanding of the link between dominance style and social play. 相似文献

Asthma is a complex polygenic disease. Many studies have implicated the importance of IL-4R alpha in the development of allergic inflammation and its gene has been implicated in the genetics of asthma and atopy. In this study, we examined the functional consequences of two of the human IL-4R alpha allelic variants that have been found to associate with asthma and atopy. We examined the effects of each variant alone and in combination on IL-4-dependent gene induction. We found that neither the Q576R nor the I75V variants affected IL-4-dependent CD23 expression. However, the combination of V75R576 resulted in expression of an IL-4R alpha with enhanced sensitivity to IL-4. We next examined the genetics of five of the known IL-4R alpha allelic variants in asthmatic and nonatopic populations. Strikingly, the association of V75/R576 with atopic asthma was greater than either allele alone and the association of R576 with atopic asthma was dependent on the coexistence of V75. A haplotype analysis revealed a single IL-4R alpha haplotype that was associated with allergic asthma, VACRS, further confirming the importance of the V75 and R576 combination in the genetics of asthma. This is the first report demonstrating that a functional alteration in IL-4R alpha requires the coexistence of two naturally occurring single nucleotide polymorphisms (snps) in combination; neither snp alone is sufficient. These data illustrate the importance of studying snps in combination, because the functional significance of a given snp may only be evident in a specific setting of additional snps in the same or different genes. 相似文献
