“…Later, Ismail, Hasan, El‐Orfali, Ismail, and Khawaja () reported that daily oral administration of Δ9‐THC/SO combination, over a period of 21 days, attenuated erythrocyte sedimentation rate scores and proinflammatory cytokines, including TNF‐α, IL‐1β, and IL‐6 levels, to normal values and MTX‐treated values on adjuvant‐induced arthritis rat model (Ismail et al, ). Some in vitro studies also showed that SO has potent antiinflammatory properties by downregulating inflammatory markers as seen with LPS‐induced inflammation in RAW macrophages or mouse peritoneal macrophages (Deme, Narasimhulu, & Parthasarathy, ; Narasimhulu, Burge, Doomra, Riad, & Parthasarathy, ; Selvarajan, Narasimhulu, Bapputty, & Parthasarathy, ). The atherosclerosis polymerase chain reaction (PCR) array revealed downregulation of a number of inflammatory markers such as Ccl2 or MCP‐1, Ccl5 or RANTES, IL‐1α, IL‐1β, and TNF in the presence of SO (Selvarajan et al, ).…”
