    • This invention, in one aspect, relates to synthetic immunoreactive peptides. These peptides are approximately 20-25 amino acids in length which are portions of the N termini of the M proteins of the most prevalent United States (U.S.) Group A Streptococcus (GAS) serotypes. At least some of the synthetic peptides can be recognized by M type-specific antibodies and are capable of eliciting functional opsonic antibodies and/or anti-attachment antibodies without eliciting tissue cross-reactive antibodies. In another aspect, it relates to compositions or vaccines comprising these synthetic serotype-specific peptides, including polypeptides and proteins. The invention may also be isolated antibodies which are raised in response to the peptides, compositions or vaccines. The invention further relates to kits for using the peptides, compositions, or antibodies. In still further aspects, the invention also relates to methods for using the peptides, compositions, vaccines, or antibodies and methods for tailoring vaccines.
    • 本发明在一个方面涉及合成免疫反应肽。 这些肽的长度约为20-25个氨基酸,它们是最流行的美国(A)链球菌(GAS)血清型的M蛋白的N末端的部分。 至少一些合成肽可被M型特异性抗体识别,并且能够引发功能性调理抗体和/或抗附着抗体而不引发组织交叉反应性抗体。 另一方面,本发明涉及包含这些合成血清型特异性肽(包括多肽和蛋白质)的组合物或疫苗。 本发明还可以是响应于肽,组合物或疫苗引起的分离的抗体。 本发明还涉及使用肽,组合物或抗体的试剂盒。 在另外的方面,本发明还涉及使用肽,组合物,疫苗或抗体的方法和用于定制疫苗的方法。

    • The present disclosure provides a cDNA, protein sequence, and genomic structure of the human cardiac isoform of myosin light chain kinase (cMLCK), and describes mutations in the cMLCK gene that are associated with cardiac dysfunction. Methods are provided for identifying individuals who can harbor mutations in the cMLCK gene, or carry alleles that can predisposed them to cardiac dysfunction. Disclosed also is a significant role for cMLCK in modulating cardiac contractility. The cMLCK protein is shown herein to reduce the amplitude of stretch activation and increase the tension production, a property of muscle which has heretofore had an unknown role in cardiac contraction. Moreover, the cMLCK protein is shown to be regionally distributed in the heart, thereby having differential effects on contractility and stretch activation. Methods herein are provided to exploit this effect of cMLCK, to treat individuals who have or are prone to cardiac dysfunction. In addition, methods are provided to identify agents that modulate cMLCK activity, thereby having potential therapeutic importance in the treatment of cardiac dysfunction.
    • 本公开提供肌球蛋白轻链激酶(cMLCK)的人心脏同种型的cDNA,蛋白质序列和基因组结构,并描述与心脏功能障碍相关的cMLCK基因中的突变。 提供了用于鉴定可以在cMLCK基因中存在突变的个体的携带方法,或携带可将它们倾向于心脏功能障碍的等位基因。 还公开了cMLCK调节心脏收缩力的重要作用。 本文显示了cMLCK蛋白以减少拉伸活化的幅度并增加张力产生,这是迄今在心脏收缩中未知作用的肌肉的性质。 此外,cMLCK蛋白质显示在区域分布在心脏中,从而对收缩性和拉伸活化具有不同的影响。 提供本文的方法以利用cMLCK的这种作用来治疗患有或易于发生心脏功能障碍的个体。 此外,提供了用于鉴定调节cMLCK活性的药剂的方法,从而在治疗心脏功能障碍中具有潜在的治疗重要性。

    • A method is disclosed herein for inducing differentiation of a B cell progenitor into a memory B cells and/or a plasma cell. The method includes contacting a population of cells including a mature B cell or a B cell progenitor with an effective amount of IL-21, and isolating memory B cells or plasma cells. In one embodiment, the B cell progenitor is an immature B cell. A method is also disclosed for enhancing an immune response. The method includes contacting a population of cells including a B cell progenitor with an effective amount of IL-21, and isolating memory B cells or plasma cells. The memory B cells and/or the plasma cell are then introduced into the subject to enhance the immune response. A method is also disclosed for treating a subject with a condition comprising a specific deficiency of at least one of memory B cells and plasma cells. A method is disclosed for identifying an agent with a physiological effect on one or more of a memory B cell and a plasma cell differentiation. A method is also disclosed for identifying agents that inhibit an activity of IL-21. Methods are also disclosed for inducing apoptosis of a B cell and for decreasing the number of B cells. A method is also described for producing a B cell hybridoma.
