Evidences for vagus nerve in maintenance of immune balance and transmission of immune information from gut to brain in STM-infected rats

Figure 1 In Figures E1 and E3 show the normal structures of the villus and mesenteric lymph node in saline-injected rats; 2 and 4 show the villus and mesenteric lymph node in STM-challenged rats. 5 and 9 show Fos expression in PVN and SON respectively in NS + sham rats; 6 and 10 show Fos expressions in PVN and SON respectively in STM + sham rat; 7 and 11 show Fos expressions in PVN and SON respectively in STM + vagotomy rat; 8 and 12 show Fos expressions in PVN and SON respectively in NS + vagotomy rat. × 50
