In-vitro type 1 IFN production following Gripp-Heel^® incubation. Effect of Gripp-Heel^® on type 1 IFN production in HRV-UV infected HeLa (a) and HSV-UV-co-stimulated PBMCs (b) was determined using IFN-α specific ELISA 4 days after incubation. In figure a data represent mean values ± SD (N = 3). For the PBMC setting (b) 4 different donors were used for each treatment group (first column = donor 1, second column = donor 2, third column = donor 3, fourth column = donor 4).
