Figure 1. Arthritis score in mice varying in hTNFα and SphK1 status.
7 month old littermates of hTNF/SphK1-/-show decreased severity and progression of arthritis. Less disease noted in the hTNF/SphK1-/- mice compared to hTNF/SphK1+/+ mice (A). Observed arthritis scores in groups varying in SphK1 and TNFα genotype from 3 months to 6 months of age (B). Decreased severity and disease progression is observed in hTNF/SphK1-/- mice compared to hTNF/SphK1+/+ mice. Data are presented as mean +/- SEM, n>16 mice/group, p< 0.05, 0.01 by ANOVA.
