Background – The caninised monoclonal antibody lokivetmab (LKV), directed at interleukin (IL)‐31, is very effective at controlling pruritus in most dogs with atopic dermatitis (AD). However, evidence exists that IL‐31 is not required for the induction of acute allergic skin inflammation, which might explain why this treatment is less efficacious in ...

Factors that shape large‐scale gradients in clonality
Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

从江浙蝮蛇毒腺中抽提总RNA,RT-PCR进行体外扩增,获得江浙蝮蛇蛇毒蛋白C激活因子基因,克隆至pGEx-5x-3载体中.对3个重组克隆分别作DNA全序列分析,通过遗传密码推导出相应的氨基酸序列.与其它已知的丝氨酸蛋白酶型蛇毒蛋白的氨基酸作比较,其中许多位置上氨基酸有很强的同源性.该基因的成功克隆,不仅推导出江浙蝮蛇蛇毒蛋白C激活因子的蛋白质序列,也为进一步开展江浙蝮蛇蛇毒蛋白C激活因子蛋白质工程的研究工作打下良好的基础.

Updated insights into the molecular pathogenesis of canine atopic dermatitis
Abstract Atopic dermatitis (AD) is a common and chronic inflammatory skin disease with frequent relapses. The genomics revolution has greatly contributed and revolutionised our knowledge of human AD; understanding the molecular skin fingerprint of AD and associated pathogenic immune pathways has led to preclinical assessments of several novel ...

General‐purpose genotypes and evolution of higher plasticity in clonality underlie knotweed invasion
Summary Many widespread invasive plant species express high phenotypic variation across novel environments, providing a unique opportunity to examine ecological and evolutionary dynamics under global change. However, studies often lack information about the origin of introduced populations, limiting our understanding of post‐introduction evolution.
