Ci that HVEM KO corneas have and that foci in WT

Values above the red line represent increased expression in comparison with that L4 proteins are increasingly associated with linezolid resistance. In this study observed with mock-infected controls. Statistically important differences are indicated as follows: **, P 0.01; ***, P 0.001 (two-tailed t test with Holm-Sidak's adjustment for numerous comparisons).?mbio.asm.orgEdwards et al.FIG 5 HVEM KO corneas have decreased stromal immune cell infiltratesduring acute infection and title= bmjopen-2016-012517 the chronic phase. (A) Representative immunohistochemical analysis of complete WT or HVEM KO eyes 1 day just after mock infection or infection in the corneal surface with two.0 106 PFU/5 l per eye of HSV-1/17 (original magnification, 400). Paraffin-embedded eyes were serially sectioned and stained for HSV-1 or markers of immune cell infiltration. Gr-1 stains granulocytes, including PMN, macrophages, and monocytes, even though CD3 is specific for T cells. A representative image of an HSV-infected region within the WT corneal epithelium is adjacent to a stromal region floridly positive for Gr-1 and CD3 (third column), although in an HVEM KO section, fewer Gr-1 and CD3 cells have been located within the stroma regardless of the presence of HSV antigen (Ag) (fourth column). The mock-infected sections contained no distinct HSV staining and only occasional Gr-1 cells. (B) Representative pictures of WT or HVEM KO eyes 14 days immediately after mock infection or infection with HSV-1 following corneal scarification. HSV antigen was absent in the cornea at this time, as expected.Ci that HVEM KO corneas have and that foci in WT corneas also tended to be larger (22). Consistent with these findings, Fig. 5A qualitatively demonstrates that HVEM KO corneas had fewer and smaller infectious foci inside the corneal epithelium than WT corneas straight away after infection (1 dpi). By 5 dpi, HSV antigen was detectable only seldom inside the corneas of each genotypes (data not shown), and no virus was discovered inside the cornea by 14 dpi (Fig. 5B, top row). Serial sections adjacent to infectious foci had been stained with anti-Ly-6G (Gr-1) to visualize monocytes and granulocytes, which includes peripheral neutrophils, or with anti-CD3 to determine T cells. The stroma of HVEM KO corneas qualitatively displayed markedly significantly less Gr-1 or CD3 staining 1 dpi than the stroma of WT corneas (Fig. 5A, second and third rows).
