摘要: 【目的】研究大白猪、长白猪的白细胞抗原复合体(swine leukocyte antigen,SLA)区域微卫星遗传多样性,探讨单倍型与免疫参数的相关性,为猪抗病育种提供参考依据。【方法】在SLA区域内筛选了13个多态性丰富的微卫星座位计算遗传多样性,并在Ⅰ、Ⅱ类区域筛选靠近功能基因且多态性丰富的微卫星进行单倍型分型,分析单倍型与免疫参数的关联。【结果】大白猪的期望杂合度( =0.70)和多态信息含量( =0.65)均分别高于长白猪( =0.67, =0.62);Ⅰ类区域6种单倍型与免疫参数的多重比较表明,H2的红细胞平均血红蛋白浓度(mean corpuscular hemoglobin concentration,MCHC)分别显著高于H3和H5的值(P<0.05,P<0.01);H2的血小板分布宽度(platelet distribution width,PDW)显著低于H3的值(P<0.05)。Ⅱ类区域的12种单倍型与免疫参数的多重比较表明,H1′的红细胞计数(red blood cell count,RBC)差异显著低于H6′、H9′对应的值(P<0.05);H1′的淋巴细胞(lymphocytes,LYM)百分比显著低于单倍型H7′的值(P<0.05),极显著低于H6′、H9′和H11′的值(P<0.01);H6′的MCHC的数值显著低于H7′的值(P<0.05),极显著低于H1′、H11′的值(P<0.01);H9′的MCHC的值显著低于H1′、H7′和H11′的值(P<0.05);H9′的红细胞平均体积(mean corpuscular volume, MCV)显著低于单倍型H1′、H6′和H11′的值(P<0.05),极显著低于H7′的值(P<0.01);H11′的单核细胞(monocytes,MONO)百分比显著低于H6′、H7′(P<0.05)和H1′的值(P<0.01),H6′、H7′和H9′的值分别显著低于H1′的值(P<0.05,P<0.01)。【结论】大白猪的SLA微卫星遗传多样性高于长白猪,SLA区域不同微卫星单倍型与免疫参数PDW、MCHC、RBC、MCV、LYM、MONO存在关联,这可进一步用于猪的健康指数的评价。

Abstract: 【Objective】 The polymorphisms and the haplotypes of the swine leukocyte antigen complex (SLA) were investigated in Landrace and Yorkshire pigs using microsatellites (MS). The association between haplotypes and immune parameters was analyzed in order to provide references for disease resistance breeding in pigs.【Method】The genetic diversity parameters were calculated by thirteen microsatellites, which were in SLA region, the haplotypes in class Ⅰ and class Ⅱ were typed by some selected microsatellites typing, and the association between haplotypes and immune parameters were studied by microsatellites in class Ⅰand class Ⅱ regions.【Result】The expected heterozygosity ( =0.70) and polymorphism information content ( =0.65) of Yorkshire pigs were higher than those( =0.67, =0.62)of Landrace pigs, respectively. The multiple comparison results of six haplotypes and immune parameters in SLA Ⅰ showed that the mean corpuscular hemoglobin concentration (MCHC) of H2 was higher than that of H3 (P<0.05) and H5 (P<0.01), respectively. The platelet distribution width (PDW) of H2 was lower than that of H3 (P<0.05). The results of multiple comparisons between twelve haplotypes and immune parameters in SLAⅡ showed that the mean of red blood cell count (RBC) of H1′ was lower than that of H6′ and H9′ (P<0.05), respectively. The value of lymphocytes ratio (LYM) of H1′ was lower than that of H7′ (P<0.05), and extremely lower than that of H6′, H9′ and H11′ (P<0.01), respectively. The mean of MCHC of H6′was lower than that of H7′ (P<0.05), H1′ and H11′ (P<0.01), while the value of MCHC of H9′ was lower than that of H1′, H7′ and H11′ (P<0.05), respectively. The mean corpuscular volume (MCV) of H9′ was lower than that of H1′, H6′ and H11′ (P<0.05) and extremely lower than that of H7′ (P<0.01), respectively. The value of monocytes ratio (MONO) of H11′ was significantly lower than that of H6′, H7′ (P<0.05) and H1′ (P<0.01), while the value of H6′, H7′and H9′ was lower than that of H1′ (P<0.05, P<0.01), respectively.【Conclusion】The polymorphisms of Yorkshire pigs were higher than those of Landrace pigs, and the associations were detected between some haplotypes of SLA-MS and immune parameters, which were PDW, MCHC, RBC, MCV, LYM and MONO. These results could be used in evaluation of health index in future.
