To Identify Genes Encoding the Receptors for the Cytokines IL-2

question 28

Multiple Choice

To identify genes encoding the receptors for the cytokines IL-2, IL-4, and IL-7, an siRNA screen is performed using purified T lymphocytes. To identify siRNAs that knock-down cytokine receptor expression, the T cells have been transfected with a construct that produces green fluorescent protein (GFP) when any one of these three cytokines is used to stimulate the cells. When the screen is completed, several different siRNAs have been identified that substantially reduce the T cells ability to respond to these cytokines as shown in Figure .
