"The aim of this study was to examine the proliferation of peripheral blood mononuclear cells due to low energy 632.8-nm He-Ne laser application. The results of previous studies supported the hypothesis that low level laser therapy (LLLT) might have an increasing effect on the proliferation of lymphocytes and production of cytokines ..... Our results showed that He-Ne laser application enhanced the proliferation significantly". (full abstract)
