CD30 Ligand/TNFSF8 蛋白, Human (HEK293, mFc)

CD30 Ligand is a B cell surface antigen and a ligand for CD30 (TNFRSF8), playing an inhibitory role in CD40-mediated immunoglobulin class switching^[1]. CD30 Ligand is also a a marker for Hodgkin lymphoma and related hematologic malignancies, involves in activation and functioning of the T cell-dependent immune system^[2]. CD30 ligand is expressed by T and B lymphocytes, macrophages, and a variety of normal haematopoietic cells and derived tumours. CD30 ligand exerts pleiotropic effects on normal and malignant lymphoid cells, including death, differentiation, or cell division^[3]. As for CD30 ligand in human is a type II membrane-associated glycoprotein belonging to the tumor necrosis factor (TNF) family. CD30 Ligand/TNFSF8 Protein, Human (HEK293, mFc) is 172 amino acids in length (Q63-D234) and is expressed in the HEK293 cells with a N-terminal mFc-tag.

CD30 配体 (CD30L) 是一种 B 细胞表面抗原，也是 CD30 (TNFRSF8) 的配体，在 CD40 介导的免疫球蛋白类别转换中发挥抑制作用^[1]。
CD30L 是一种类型II 膜相关糖蛋白，属于肿瘤坏死因子 (TNF) 家族，结构上与肿瘤坏死超家族成员 TNF α、TNF β 和 CD40 相关^[1][3]。
CD30L可增强某些淋巴瘤细胞系的细胞增殖，同时诱导其他淋巴瘤细胞系的细胞死亡并减少细胞增殖，从而在霍奇金和某些非霍奇金淋巴瘤中发挥病理生理作用。CD30L 还可增强细胞因子 IL-6、TNF、LT-a^[2] 的释放。
CD30L 对正常和恶性淋巴细胞发挥多效作用，包括死亡、分化或细胞分裂调节^[3]。
CD30L主要表达于活化的T细胞、B细胞、巨噬细胞和DC上，而CD30/CD30L主要表达于固有层活化的CD4+T细胞表面（ LP），尤其是在 Th17 细胞分化的早期阶段。CD30L 缺乏可抑制肠粘膜中 Th17 细胞的分化和 IL-17A 的产生^[4]。
CD30L 作为促炎细胞因子，参与溃疡性结肠炎的适应性免疫反应结肠炎（UC），其水平与UC的严重程度呈正相关^[5]。
