Figure Lengend Snippet: Effect of rhIFNα-2b on VEC viability . VK2/E6E7 cells were treated with rhIFNα-2b for 24 h. The mean values for the remaining four values and standard deviations (error bars) are shown. ∗∗∗ , significant difference compared to 0 mg/mL of rhIFNα-2b control group ( P < 0.0001).

Article Snippet: Human VEC line, VK2/E6E7 cells (ATCC ® CRL-2616), were obtained from the American Type Culture Collection (Rockville, MD, USA) and grown cultured in K-SFM (Gibco, USA) supplemented with 5 ng/mL recombinant epidermal growth factor and 50 μg/mL bovine pituitary extract (Invitrogen Corporation, Grand Island, NY, USA) with 100 units/mL each of penicillin and streptomycin (Life Technologies, Grand Island, NY, USA) at 37°C with 5% CO 2 in a high humidity environment.

Figure Lengend Snippet: Effect of rhIFNα-2b on the production of IL-2 (A) , IL-4 (B) , IL-6 (C) , IL-8 (D) , and IL-17 (E) (expressed as pg/mL) by the VEC line, VK2/E6E7 cells cultivated alone, grown with 1.25 mg/mL rhIFNα-2b, and infected with C. albicans (1 × 10 5 /mL). The supernatants were collected and the cytokine levels were assessed by performing an ELISA 12 h post-infection and a subsequent 24 h of co-incubation with 1.25 mg/mL of rhIFNα-2b. V represents the VECs cultivated alone; V+I represents VECs co-incubated with 1.25 mg/mL of rhIFNα-2b for 24 h; V+C represents VECs infected with Candida albicans for 12 h; V+C+I represents the VECs infected with C. albicans for 12 h, then treated with 1.25 mg/mL of rhIFNα-2b for another 24 h. ∗∗ , significant difference compared to the V group ( P < 0.001); ∗∗∗ , significant difference compared to the V group ( P < 0.0001).

Figure Lengend Snippet: Effect of rhIFNα-2b on the production of vaginal epithelial-derived IgG (expressed in μg/mL) by the VEC line, VK2/E6E7 cells . Supernatants were collected, and the IgG levels were assessed by performing an ELISA after 12 h of infection and a subsequent 24 h of co-incubation with rhIFNα-2b. V represents the VECs cultivated alone; V+I represents the VECs co-incubated with 1.25 mg/mL of rhIFNα-2b for 24 h; V+C represents the VECs infected with C. albicans for 12 h; V+C+I represents the VECs infected with C. albicans for 12 h, then treated with 1.25 mg/mL of rhIFNα-2b for another 24 h. ∗∗∗ , significant difference compared to the V group ( P < 0.0001); ∗∗ , significant difference compared to the V+C group ( P = 0.004). Each sample was repeated three times. The error bars indicate the standard deviation.
