"An Interferon Gamma (IFN-gamma) and Interleukin-4 (IL-4) Whole Blood Assay to Detect T Cell Response to Antigens in HIV-1 Infected Patients."

According to an abstract submitted by the authors to the Ninth Symposium on HIV Infection entitled From Virology ... To Therapy, held March 6-8, 1997, in Toulon, France, "Objective: We developed an heparinized whole blood (HWB) assay to measure T cell mediated immune responses to HIV and recall antigens. Methods: The cultures were performed in 96-well plates in which 25 (mu)l of whole blood was required. We studied the production of IFN-gamma and IL4 in short term culture (24 and 48h) of 1/10 diluted HWB cultures from 15 healthy controls and 43 HIV-1 infected patients grouped according to 1993 classification of the CDC. IFN-gamma and IL-4 were measured with an...
