By five dpi, HSV antigen was detectable only hardly ever in the corneas of each genotypes (information not shown), and no virus was located inside the cornea by 14 dpi (Fig. (A) Average corneal cytokine protein concentrations (conc.)

The values are imply final results SEM from two independent experiments, with n 5 pooled samples (six corneas per sample) per group. Values above the red line represent improved expression in comparison to that observed with mock-infected controls. Statistically important variations are indicated as follows: **, P 0.01; ***, P 0.001 (two-tailed t test with Holm-Sidak's adjustment for a number of 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 at 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 LCL161 supplier markers of immune cell infiltration. Gr-1 stains granulocytes, which includes PMN, macrophages, and monocytes, whilst CD3 is certain for T cells. A representative image of an HSV-infected area within the WT corneal epithelium is adjacent to a stromal area floridly good for Gr-1 and CD3 (third column), when in an HVEM KO section, fewer Gr-1 and CD3 cells have been found inside the stroma despite the presence of HSV antigen (Ag) (fourth column). The mock-infected sections contained no specific HSV staining and only occasional Gr-1 cells. (B) Representative images of WT or HVEM KO eyes 14 days following mock infection or infection with HSV-1 soon after 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). Constant 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 following infection (1 dpi). By five dpi, HSV antigen was detectable only rarely inside the corneas of each genotypes (data not shown), and no virus was discovered in 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, such as peripheral neutrophils, or with anti-CD3 to recognize T cells. The stroma of HVEM KO corneas qualitatively displayed markedly less Gr-1 or CD3 staining 1 dpi than the stroma of WT corneas (Fig.
