1 Lysophospholipids and ATP mutually suppress maturation and release of IL-1 beta in mouse microglial cells using a Rho-dependent pathway. Adenosine Triphosphate interleukin 1 beta Mus musculus
2 In this study, we determined whether the lysophospholipids, i.e., LPC and sphingosylphosphorylcholine (SPC), modulate the ATP-induced release and processing of IL-1beta mediated by P2X7R in mouse MG6 microglial cells. Adenosine Triphosphate interleukin 1 beta Mus musculus
3 However, these lysophospholipids inhibited ATP-induced caspase-1 activation that is usually followed by the release of mIL-1beta. Adenosine Triphosphate interleukin 1 beta Mus musculus
4 Conversely, ATP inhibited the release of pro-IL-1beta and mIL-1beta induced by LPC/SPC. Adenosine Triphosphate interleukin 1 beta Mus musculus
5 Conversely, ATP inhibited the release of pro-IL-1beta and mIL-1beta induced by LPC/SPC. Adenosine Triphosphate interleukin 1 beta Mus musculus
6 This suggests that lysophospholipids and ATP mutually suppressed each function to release IL-1beta. Adenosine Triphosphate interleukin 1 beta Mus musculus
7 In addition, the microtubule inhibitor colchicine inhibited ATP-induced release of mIL-1beta similar to that of LPC and SPC. Adenosine Triphosphate interleukin 1 beta Mus musculus
8 This suggests that the impairment of the microtubule reassembly may be associated with the inhibitory effects of LPC/SPC on ATP-induced mIL-1beta release. Adenosine Triphosphate interleukin 1 beta Mus musculus
9 Mutual suppression by ATP and LPC/SPC on the maturation of IL-1beta was observed in LPS-primed primary microglia. Adenosine Triphosphate interleukin 1 beta Mus musculus
