In the original article, there was a mistake in Figure 6 as published. The wrong representative FACS plot was inserted for L31/CCR2KO in Figure 6A. The corrected Figure 6 appears below.
Figure 6
The impact of CX3CR1 and CCR2 deficiency on monocyte/macrophage and CD8+ T cells survival and function in L31 mice. (A) Representative flow cytometry plot and quantitative analysis of monocytes apoptosis. Compared to L31 and L31/CCR2KO mice, increased monocyte death was observed in the blood of L31/CX3CR1KO mice. (B) Similar level of cell proliferation was seen in L31 and L31/CX3CR1KO mice, indicating that no enhanced proliferation occurred to compensate the increased cell death. Monocyte cell proliferation was barely detectable in L31/CCR2KO mice. (C) CD8+ T cells apoptosis (Annexin V+/7-AAD-) was observed essentially in L31/CX3CR1KO mice. (D) The majority of apoptotic CD8+ T cells were of the activated phenotype (CD44+CD43+). (E) Proliferation of CD8+ T cells was similar in all three groups, L31, L31/CX3CR1KO and L31/CCR2KO mice, showing no enhanced proliferation to compensate for CD8+ T cell death in L31/CX3CR1KO mice. (F) Macrophage proliferation was strongly enhanced in L31/CCR2KO mice, 87% (Ki67+ cells over total nerve macrophages (F4/80CD11b) in L31/CCR2KO mice and 58% in L31 mice. (G) mean fluorescent intensity (MFI) depicts the amount of phagocytosed beads by nerve macrophages. The highest MFI was observed in L31and L31/CCR2KO mice, which was significantly reduced in L31/CX3CR1KO mice. Quantification in A-E depicted the number of cells per µl blood. Quantification in F depicted the number of cells per a segment of 2 cm long sciatic nerve. Disease was induced by PSNL, and experiments done 30 days post PSNL. n=5-6/group; student’s t test; *p < 0.05; **p < 0.01; ***p < 0.001.
