Platelet-rich plasma (PRP) is a multifunctional blood product containing highly concentrated platelets, and various cell growth factors which promote cell proliferation and differentiation. PRP exhibited benefits in injurious articular cartilage repair and the removal of inflammatory factors in clinical studies. Rheumatoid arthritis (RA) is an autoimmune disease manifesting primarily as inflammatory arthritis, which is associated with notable morbidity in humans. In the present study, the therapeutic effects and primary mechanism of PRP on a type II collagen‑induced arthritis (CIA) mouse model was investigated. Inflammatory factors interleukin (IL)‑6, IL‑8, IL‑17, IL‑1β, tumor necrosis factor (TNF)‑α and interferon (IFN)‑γ were analyzed in PRP and PBS‑treated groups. Vascular endothelial growth factor (VEGF), platelet‑derived growth factor (PDGF), insulin‑like growth factor (IGF)‑1 and transforming growth factor (TGF)‑β expression in peripheral whole blood was additionally analyzed. The therapeutic efficacy of PRP for RA mice was evaluated using clinical arthritis scores. The results of the present study demonstrated that treatment with PRP alleviated arthritis, and reduced humoral and cellular immune responses, leading to beneficial effects on histological parameters as observed using joint tissue histological staining. CIA mice treated with PRP exhibited downregulated expression of IL‑6, IL‑8, IL‑17A, IL‑1β, TNF‑α, receptor activator for nuclear factor‑κB and IFN‑γ in inflammatory tissue. In addition, VEGF, PDGF, IGF‑1 and TGF‑β expression in peripheral whole blood was increased following treatment with PRP. The serum concentration of anti‑collagen antibody was decreased in PRP‑treated CIA mice. In conclusion, CIA mice treated with PRP exhibited beneficial effects, including decreased joint inflammation, cartilage destruction and bone damage, and increased repair of joint tissue. The results of the present study suggested that PRP may be an effective therapeutic agent for RA.
