    • Novel structural forms of T cell costimulatory molecules are described. These structural forms comprise a novel structural domain or have a structural domain deleted or added. The structural forms correspond to naturally-occurring alternatively spliced forms of T cell costimulatory molecules or variants thereof which can be produced by standard recombinant DNA techniques. In one embodiment, the T cell costimulatory molecule of the invention contains a novel cytoplasmic domain. In another embodiment, the T cell costimulatory molecule of the invention contains a novel signal peptide domain or has an immunoglobulin variable region-like domain deleted. The novel structural forms of T cell costimulatory molecules can be used to identify agents which stimulate the expression of alternative forms of costimulatory molecules and to identify components of the signal transduction pathway which results in costimulation of T cells.
    • 描述了T细胞共刺激分子的新型结构形式。 这些结构形式包括一个新的结构域或者具有缺失或添加的结构域。 结构形式对应于可以通过标准重组DNA技术产生的天然存在的可变剪接形式的T细胞共刺激分子或其变体。 在一个实施方案中,本发明的T细胞共刺激分子含有新的细胞质结构域。 在另一个实施方案中,本发明的T细胞共刺激分子含有新的信号肽结构域或具有免疫球蛋白可变区域结构域缺失。 T细胞共刺激分子的新型结构形式可用于鉴定刺激替代形式的共刺激分子表达的试剂,并鉴定导致T细胞共刺激的信号转导通路的成分。
