Fig. 7From: Active immunization with human interleukin-15 induces neutralizing antibodies in non-human primatesEffect of serum on TNF-α production mediated by IL-15 in synovial cells from RA patients. Synovial fluid cells were incubated with serum (fixed dilution 1:1000), or with 60 ng/ml of IL-15, or a combination of both. After incubation, supernatants were collected and levels of human TNF-α were quantified by ELISA. The tested serum corresponds to one animal from the Alum group and was taken 15 days after the third immunizationBack to article page
