Cytokine gene expression : analysis using northern blotting, polymerase chain reaction and in situ hybridization

Journal article (peer-reviewed)abstract
- We describe here the use of northern blotting, PCR and in situ hybridization for the analysis of cytokine gene expression. These techniques, each with their advantages and disadvantages, have been used to monitor cytokine gene expression in sites of immune reactivity and in the developing thymus. Whilst expression of a gene usually correlates well with protein production from that gene, this may not always be the case. The development of methods to analyze protein production in situ, for instance by immunohistochemistry, together with analysis of mRNA expression will allow us to begin to understand the role of cytokines within the immune system of the intact animal.

Expression of an interferon-gamma-like substance in normal and transplanted rat heart tissue
- 1992

In: J Heart Lung Transplant. ; 11:1 Pt 1, s. 142-6
-
Journal article (peer-reviewed)abstract
- The presence of interferon-gamma-like molecules has been reported not only in lymphocytes, but also in certain nerve cells and in normal skeletal muscle. We have studied the reactivity of the anti-interferon-gamma monoclonal antibody DB1 with frozen sections of normal and transplanted rat hearts. Cardiac grafts from PVG donor rats were transplanted to syngeneic PVG recipients or allogeneic Wistar/Kyoto recipient rats with the use of an accessory cervical heart transplantation technique. The allogeneic heart transplants were harvested 4 days and the syngeneic grafts 4 weeks after transplantation. In normal hearts there was a weak but distinct reactivity with the anti-interferon-gamma antibody in most muscle cells. In addition, some lymphocytes and the Purkinje fibers were positive. Hearts transplanted over an allogeneic barrier revealed that staining for interferon-gamma on muscle cells was substantially increased whereas no or only a moderate increase in the anti-interferon-gamma staining was seen in hearts transplanted to syngeneic recipients. These data indicate that interferon-gamma present in rat myocyte may be involved in the pathophysiology of graft rejection and also suggest that interferon-gamma may be of importance for the function of normal rat heart muscle cells.
