Lobular panniculitis after subcutaneous administration of interleukin-2 (IL-2), and its exacerbation during intravenous therapy with IL-2

Cellular expression of interleukin 2 (IL-2) and its receptor (IL-2R, CD25) in lung tumours.

In view of the unclear prognostic and diagnostic role of interleukin 2 (IL-2) and its receptor in human tumours, we examined the cellular expression of IL-2 and of the subunit alpha of its receptor (IL-2Ralpha, CD25) in relation to the proliferative activity of various subtypes of lung tumours. The immunocytochemical ABC technique was applied to archival tissue material of neuroendocrine lung t...

Serum TNF-α, IL-10 and IL-2 in Schizophrenic Patients Before and After Treatment with Risperidone and Clozapine

Background: Schizophrenia is a disorder of the executive function of both sensory and central nervous system. Recent studies suggest that immune mechanisms play a role in the pathophysiology of this disease. The variations in cytokine concentrations have been associated with psychopathology and treatment of schizophrenia. Objective: To investigate the changes in serum concentrations of TNF- α, ...

Complete metastasectomy after high-dose interleukin-2 (HD IL-2) therapy for melanoma

Methods A retrospective chart review was performed on patients with metastatic melanoma seen at Saint Louis University from January 1999-June 2011 who were partial responders to HD IL-2 therapy (720,000 IU/kg per dose intravenously; 14 doses, 2 cycles per course, maximum 2 courses). Survival estimates for patients that were able to undergo complete metastasectomy after HD IL-2 were compared to ...

Interleukin 2 (IL-2) augments transcription of the IL-2 receptor gene.

We demonstrate that purified interleukin 2 (IL-2) can directly upregulate IL-2 receptor expression on phytohemagglutinin-activated T lymphocytes maintained in culture until IL-2 receptor expression had markedly declined. The IL-2-induced increase in IL-2 receptor number is maximal within 12 hr, requires new RNA and protein synthesis, and is mediated by an interaction of ligand with the high-aff...
