前列腺素E2是由活化血小板产生的信号传导分子。活化血小板释放PGE2是活化血小板利用邻近红细胞帮助血块形成的机制的一部分。本品浓度为10-10sup M时，可使人红细胞的滤过性降低约30％，还能导致平均细胞容积减少约10％。细胞收缩是由于诱导PGE2刺激的K+外排途径，导致细胞K+离子的快速流失。已有研究证明这种K+离子流失与Ca2+有关。已有研究证明PGE2可刺激新生小鼠顶骨产生白细胞介素-6（IL-6）。培养6小时后，用10-8sup M PGE2刺激的细胞比对照组细胞产生的IL-6显著增多。与前列腺素F2α不同，PGE2的致热活性不受地塞米松抑制。

Tumors can suppress the host immune system by employing a variety of cellular immune modulators, such as regulatory T cells, tumor-associated macrophages, and myeloid-derived suppressor cells (MDSC). In the peripheral blood of patients with advanced stage melanoma, there is an
Prostaglandins are one of the major groups of chemical mediators in the mammalian body. Among prostaglandins, prostaglandin E2 (PGE2) is the most abundant prostanoid in humans and involved in regulating many different fundamental biological functions. PGE2 signaling is mediated by
