doi: 10.1002/jor.24682
Figure Lengend Snippet: Blocking IL-6 abolishes degenerative IVD induced elevated neuron activity in response to mechanical stimulation. A, The percentage of rat DRG neurons exhibiting calcium transients as a function of strain fitted to a Boltzman curve for the control media, degenerative IVD conditioned media and degenerative IVD conditioned media supplemented with IL-6 blocking antibody (n = 5 patients) groups. B, The maximum calcium transients of rat DRG neurons exposed to mechanical strain in the presence of control media, degenerative IVD conditioned media, and degenerative IVD conditioned media supplemented with IL-6 blocking antibody. C,D, The S50 (C) and Smax (D) generated from dose-response curve fitting for the control media, degenerative IVD conditioned media, and degenerative IVD conditioned media supplemented with IL-6 blocking antibody. A, Values are mean ± SD. *P < .05 compared to control media group at same strain level. Error bars are SD. B-D, Values are mean ± SD. *P < .05 compared to control media group. Error bars are SD. DRG, dorsal root ganglia; IL, interleukin; IVD, intervertebral disc
Article Snippet: Based on previous experience with IVD conditioned media, 32 mouse monoclonal antihuman IL-6 antibody (Life Technologies) was added to degenerative IVD conditioned media and incubated at 37°C for three hours prior to addition to neurons as described in the Degenerative IVD Conditioned Media Exposure section ( n = 5).
Techniques: Blocking Assay, Activity Assay, Generated
