Cyclosporin is a metabolite isolated from culture broths of the fungus Tolypocladium inflatum Gams which was shown to be immunosuppressive by Borel et al. in rats, mice and guinea-pigs.1.2 Cyclosporin may directly block the release of interleukin I from activated T helper cells and indirectly block the release of interleukin II from macrophages, thus suppressing both cellular and humoral immuni...

PURPOSE Immune-based inflammation has been observed as a common mechanism of keratoconjunctivitis sicca (KCS). In KCS-affected eyes, upregulated expression of HLA DR and various immune- or apoptosis-related markers by conjunctival epithelial cells has been demonstrated in an earlier study, by a technique of flow cytometry in impression cytology (IC) specimens. The purpose of this study was to m...

BACKGROUND The allergen-induced late asthmatic reaction (LAR) is associated with mucosal inflammation involving several cell types including activated T lymphocytes and eosinophils. In contrast, the early asthmatic reaction (EAR) is considered to results from rapid allergen-induced release of bronchoconstrictor mediators from IgE sensitised mast cells. Cyclosporin A has efficacy in chronic seve...

The mechanisms responsible for cyclosporin-induced encephalopathy remain controversial. Herein we present a case of cyclosporin-induced encephalopathy with unusually prolonged vasospasm, which might have contributed to the slow recovery of the patient.

We have compared the pharmacodynamic properties of calcineurin inhibitors tacrolimus and cyclosporin A in rats to clarify the different therapeutic drug monitoring strategy of both drugs in a clinical situation. In various tissue extracts, the inhibition of calcineurin activity by cyclosporin A was significantly greater than that by tacrolimus at the same drug concentration (1 microM) in the th...

Multipotent, self-renewing neural stem cells and their progeny [collectively referred to as neural precursor cells (NPCs)] represent a population of cells with great promise for CNS repair. To effectively harness their potential for therapeutic applications, the factors that regulate NPC behavior and/or fate must be well understood. The ability of immunomodulatory molecules to affect NPC behavi...

Ten patients with progressive, symptomatic interstitial lung disease of unknown aetiology who were treated with cyclosporin A were reviewed. Five had clinical and histopathological features of cryptogenic fibrosing alveolitis and five a progressive restrictive lung disease characterised by interstitial infiltration with lymphocytes and minimal fibrosis, which could not be classified precisely. ...
