The invention relates to the application of Vanilloid receptor (VR) 1 inhibitors for drug development and for the treatment of HIV-mediated neuropathies and neuropathic pain states. Further, the inventor identified a novel signaling cascade connecting the HIV receptor CXCR4 to VR1. Thus, the invention provides molecular evidence that HIV-mediated pain states - initiated upon binding of the virus to CXCR4 - can be inhibited by VR1 antagonists blocking the final execution of the CXCR4NR1 pathway. In addition, the invention demonstrates that present standard therapies for HIV-mediated pain (which do not include VR1 inhibitors) can not interfere with the CXCR4/VR1 pathway thus explaining inefficient patient treatment in the clinics.
本发明涉及Vanilloid受体(VR)1
抑制剂在药物开发和治疗HIV介导的神经病变和神经病性疼痛状态中的应用。此外,发明人还发现了一种新的信号级联,将HIV受体CXCR4连接到VR1。因此,本发明提供了分子证据,证明HIV介导的疼痛状态 - 在病毒与CXCR4结合后启动 - 可以通过VR1拮抗剂阻断CXCR4NR1途径的最终执行来抑制。此外,本发明证明目前用于治疗HIV介导的疼痛的标准疗法(不包括VR1
抑制剂)无法干扰CXCR4 / VR1途径,从而解释了临床上治疗效果不佳的原因。
