Quantitative gene analysis of mRNA copies in lacrimal gland. T-helper-associated cytokines and transcription factors and proinflammatory cytokine IL-1β were investigated in lacrimal glands of CD25KO, γDKO, and IFN-γKO mice at ages 8, 12, and 16 weeks. Bars indicate mean ± standard deviation of number of copies from eight individual samples. **P < 0.01 intrastrain CD25KO comparison; ^^ and ^^^, P < 0.01 and P < 0.001 intrastrain γDKO comparison versus age 8 weeks, respectively.
