Fig. 6: The role of TLR4 in parthanatos and the MyD88 and/or the PI3K signaling pathway in parthanatos.

One of the reasons that LPS-induced ROS production leads to parthanatos. Erlotinib could inhibit the cells surface TLR4 expression and alleviated the parthanatos in response to LPS. This may be through the MyD88 and/or the PI3K signaling pathway. Besides, erlotinib inhibits the generation of ROS, which in turns inhibits parthanatos.
