A study of the effect of salicylic acetic acid on a lymphocyte cell model of cellular activation and proliferation

Salicylic acetic acid (SAA) is a drug that has formed part of the treatment of many diseases for many years. Its anti-inflammatory activity is well known, but recently its possible role in the interference in the oncogenesis mechanisms has become apparent. With the aim of supporting these yet preliminary observations, we studied the effect of salicylic acetic acid on a cellular activation and proliferation model. d lymphocytes obtained from peripheral blood, which were later exposed to cellular activation and proliferation stimulus by the SEB antigen. Lymphocyte activation was determined by direct immunoflourescence through expression of the receptor IL-2 (CD25) α chain and proliferation through the incorporation of tritiated thymidine to the DNA in synthesis together with the determination of the cellular cycle by flow cytometry. nd that both processes, activation and proliferation, are inhibited by increasing doses of SAA.
