Since its introduction in 1979, CyA has been the immunosuppression agent of choice in clinical transplantation of all solid organs.1 More recently, a novel new immunosuppressive agent, FK 506, has been introduced in experimental transplantation.2 Most recently, it also has been introduced into clinical liver transplantation. Both agents appear to be T cell-specific and induce their immunosuppre...

Echinococcus granulosus sensu lato larvae cause cystic echinococcosis, a highly contagious zoonotic illness that poses worldwide threat to human health and development. The purpose of this study was determine the therapeutic effectiveness albendazole praziquantel, each alone in combination, vivo estimate serum levels interleukin-2, interleukin-9 interleukin-10 as biomarkers evaluating responsiv...

Twenty-five patients with Type 1 (lepra) and Type 2 (ENL) reactions, were assayed for SIL-2R in serum--before and after treatment for their acute condition--and the results were compared with 10 normal healthy adults and 20 patients of leprosy per se. Classification of each subject into different leprosy groups, and into various types and subtypes of reactions, was done according to standard cr...

The activation of LFA-1 (lymphocyte function-associated antigen) is a critical event for T cell co-stimulation. The mechanism of LFA-1 activation involves both affinity and avidity regulation, but the role of each in T cell activation remains unclear. We have identified antibodies that recognize and block different affinity states of the mouse LFA-1 I-domain. Monoclonal antibody 2D7 preferentia...

Preclinical models of advanced melanoma have shown that chronic indomethacin therapy combined with interleukin 2 (IL-2) can eradicate experimental metastases. A phase II trial was done in patients with advanced melanoma. Indomethacin and ranitidine were begun at least one week before IL-2. Of the objective responses in 3 patients, 2 were achieved on ranitidine and indomethacin alone, before sta...

It has been demonstrated that the plasma membrane expression of ZIP1 is regulated by endocytic mechanisms. In the zinc-replete condition, the level of surface expressed ZIP1 is low due to the rapid internalization of ZIP1. The present study aimed to identify a sorting signal(s) in ZIP1 that mediated endocytosis of ZIP1. Four potential sorting signals (three di-leucine-and one tyrosine-based) we...

Radiosensitivity/Ionizing radiation/Cell killing/Human T-lymphocytes In vitro culture conditions for colony formation of human fresh peripheral T-cells using PHA and recombinant Interleukin-2 are defined. Peripheral lymphocytes, from six individuals, were exposed to X or gamma rays in vitro, and dose-survival curves were obtained. The results showed typical sigmoid curves similar to those obser...

Human interleukin 2 (IL-2) analogs with defined amino acid substitutions were used to identify specific residues that interact with the 55-kDa subunit (p55) or alpha chain of the human IL-2 receptor. Analog proteins containing specific substitutions for Lys-35, Arg-38, Phe-42, or Lys-43 were inactive in competitive binding assays for p55. All of these analogs retained substantial competitive bi...

Concentrations of interleukin-2 (IL-2) and soluble IL-2 receptor (sIL-2R) in serum and CSF samples were measured in 63 patients with multiple sclerosis (MS) to evaluate their usefulness as markers of disease activity. CSF concentrations of IL-2 and sIL-2R were significantly higher in MS relapse compared with MS patients in remission or with control subjects. These concentrations correlated with...

A survey involving 81 individuals living in Dafinso and Vallée du Kou no. 4 (near Bobo-Dioulasso), Burkina Faso, was performed in June 1987, August to September 1987, and January 1988, respectively, at the beginning of, during, and after the transmission season of malaria. The clinical longitudinal study during the transmission period allowed us to define three different groups in terms of both...
