TAK-242 (CAS 243984-11-4 Cat 6587/5) was from R&D Systems (Minneapolis MN). LPS-RS (from Rhodobacter sphaeroides, Catalog # tlrl-rslps) and MCC950 (CAS 210826-40-7, Catalog # inh-mcc) were purchased from InvivoGen (San Diego CA). Other chemicals, including minocycline (CAS 13614-98-7, Cat# M2280000) and IL1-Ra (Cat# SRP 3084), and salts were obtained from Millipore Sigma Chemical Company. Drugs were prepared as stock solutions in either ACSF or DMSO and diluted to final concentration at the time of experiment. The concentrations of TAK-242, LPS-RS and minocycline are based on our previous studies using those inhibitors against LPS23 . The dose and concentrations of MCC950 and IL1-Ra followed studies by Coll et al.14 (link) and Edy et al.25 (link), respectively.
