Good clinical practice is now obligatory in academic clinical drug research in the European Union.

By May 2004, all clinical trials in the European Union (EU) on medicinal products have to be initiated and conducted in compliance with the principles in the new directive on Good Clinical Practice (GCP). This requirement will also apply to non-commercial trials involving registered drugs and may therefore restrain the academic clinical drug research. In Denmark, three public GCP units connected in a national network and associated with the university hospitals in Copenhagen, Odense and Aarhus have been established. The GCP units offer academic researchers the necessary quality assurance and quality control systems to ensure that clinical drug research can be performed according to GCP. The Danish initiative is presented here as a contribution to the future work with implementation of the principles of GCP in academic clinical drug research in the European Union.

[Public GCP unit--experiences from the Aarhus University Hospital].

According to the EU GCP-directive, all clinical trials involving medical products must adhere to the GCP-standards by May 2004. This may entail difficulties for investigator-initiated trials not sponsored by the industry. A public GCP-unit was established at Aarhus University Hospital in 1995. The unit offers researchers a monitoring system including discussion of the protocol, check of formalities, and verification of data and protocol compliance. As a contribution to the future work with GCP, experience from the GCP-unit at Aarhus University Hospital is presented here.

Human retinal pigment epithelial cells inhibit proliferation and IL2R expression of activated T cells.

The purpose of this study was to characterize the effects of human retinal pigment epithelial (RPE) cells on activated T cells. Activated T cells were cocultured with adult and foetal human RPE cells whereafter apoptosis and proliferation were determined by flow cytometry and (3)H-Thymidine incorporation assay, respectively. T cells and RPE cells were cultured directly together or in a transwell system for determination of the effect of cell contact. The importance of cell surface molecules was examined by application of a panel of blocking antibodies (CD2, CD18, CD40, CD40L, CD54, CD58) in addition to use of TCR negative T cell lines. The expression of IL2R-alpha -beta and -gamma chains of activated T cells was analysed by flow cytometry after incubation of T cells alone or with RPE cells. Human RPE cells were found to inhibit the proliferation of activated T cells by a cell contact-dependent mechanism. The RPE cells inhibitory abilities were not affected by blocking of any of the tested surface molecules. The inhibition of the T cells' proliferation correlates with a decreased expression of IL2R-beta and -gamma chains. The T cells regain their ability to proliferate and increase their IL2R-beta and -gamma chain expression within 24 hr after removal from the coculture. It is concluded that the cultured human adult and foetal RPE cells inhibit the proliferation of activated T cells by a process that does not involve apoptosis. It depends on cell contact but the involved surface molecules were not revealed. The proliferation inhibition correlates with a modulation of the T cells' expression of IL2R, and is reversible.
