The aim of the project is to analyze the plasma proteomic profile of an animal model of arthritis (Collagen Induced Arthritis; CIA) in response to different treatments. For this, plasma samples from mice under five different treatments were analyzed (N=6 per group): Vehicle, CIA, CIA + Δ9-THCA-A (20 mg / kg), CIA + Δ9-THCA-A (20 mg / kg) + T0070907 (5 mg / kg) and CIA + Δ9-THCA-A (20 mg / kg) + SR141716A (5 mg / kg).
