This video demonstrates the effect of tobacco product preparations, TPPs, on cytokine production from human peripheral blood mononuclear cells using flow cytometry. Treatment of the cells with TPP downregulates the production of pro-inflammatory cytokines, which is estimated after lipopolysaccharide stimulation, followed by immunostaining and flow cytometry analysis.
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. WS-CM Preparation Generate whole smoke-conditioned medium (WS-CM) as previously described. Prepare WS-CM by passing smoke from four 3R4F reference cigarettes through Roswell Park Memorial Institute (RPMI) 1640 medium without phenol…
