Fig 2. CCL2 binds to and alters the brush border of the intestine without being internalized. (A-D) C. elegans L4 larvae expressing PGP-1::GFP were fed with a non-toxic (100 ug/ml; A) or toxic (500 ug/ml; B-D) concentration of CCL2-TAMRA (tetramethylrhodamine: red) for the indicated hours and observed using confocal microscopy. (A) CCL2-TAMRA colocalized with PGP-1::GFP at the apical intestinal plasma membrane. (B-D) Toxic concentrations of CCL2-TAMRA led to a time-dependent alteration of the brush border without any detectable uptake into intestinal cells. Scale bar: 10 um; inset: 2x magnification of the lumenal section of the intestine.

Figure 5. Expression of GEM- 4::GFP in L1 larvae. (A and B) DIC and GFP fluorescence images of an early L1 stage animal of genotype gon-2(q388); gem-4(dx77); dxEx15[gem-4::GFP; pRF4] raised at 15C [permissive temperature for gon-2(q388)]. (C and D) DIC and GFP fluorescence images of an early L1 stage animal of genotype gon-2(q388); dxEx15 [gem-4::GFP; pRF4] raised at 25C [restrictive temperature for gon-2(q388)]. gem-4:: GFP is also localized to the intestinal brush border (bb). The granular/globular fluorescence in B and D is due to autofluorescence of gut granules. Bar, 10 um.
