Paclitaxel, a well-known anti-cancer drug, hinders cell division by stabilizing microtubules. Despite its effectiveness, paclitaxel causes neuropathic pain, possibly due to its impact on the immune system. The study investigated how paclitaxel affects CP macrophages, important for the blood-cerebrospinal fluid barrier. It focused on two types of Kolmer cell macrophages in a model of paclitaxel-induced neuropathic pain. Wistar rats received either paclitaxel or its vehicle (Ethanol and chromophore). Brains, including those from naïve rats, were collected at different intervals (1, 7, 14, and 21

The choroid plexus (ChP) is a highly vascularized non-neural tissue located in the brain ventricles and is responsible for the production of a large part of the cerebrospinal fluid (CSF). In addition, the epithelial cells of the ChP synthesize neurotrophic factors and other signalling molecules into CSF and act as a blood-cerebrospinal fluid barrier. Importantly, ChP cells harbour a robust circadian oscillator that may control ChP function and may play an important role in the circuitry between brain clocks. In this study, we aimed to find out whether the ChP clock is sensitive to a robust imm
