oids (5, 6). In our patient the titre of circulating anti-ICS antibodies was low, which might indicate a prolonged initial phase of PV before generalized development of bullae. The massive plasma cell in®ltrate seen in the lesional upper dermis may be a factor for the localization of the lesions. Another possibility is that an unknown mechanism prevents the generalization of PV, resulting in th...

OBJECTIVE To determine whether interferon alpha-2a, when utilised as adjuvant chemotherapy following ablation of condylomata acuminata (genital warts) by cryotherapy, is effective in the prevention of recurrences. DESIGN Randomised, placebo-controlled, double-blind study. Statistical analysis was by 2-tailed Fisher's Exact Test. PATIENTS 97 patients with recurrent condylomata acuminata. I...

Human Interferon β (INF-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. In this study an expression vector was designed and constructed for expression of human INF-β-1b either in shake flasks and bench top bioreactor. The designed vector was constructed based upon pET-25b(+) with T7 promoter. Recombinant human beta interferon ...

The pleiotropic activity of type I interferons has been attributed to the specific interaction of IFN with the cell-surface receptor components ifnar1 and ifnar2. To date, the structure of IFN has been solved, but not that of the receptor or the complex. In this study, the structure of the IFN-alpha 2-ifnar2 complex was generated with a docking procedure, using nuclear Overhauser effect-like di...

Highly purified murine granulocyte-macrophage progenitor cells (CFU-GM) were used as target cells to assess the possible direct effects of purified preparations of recombinant murine gamma-interferon, prostaglandin E, recombinant human heavy chain (acidic) ferritin, and recombinant human tumor necrosis factor alpha (TNF-alpha) on progenitor cells in vitro. Target CFU-GM, with cloning efficienci...
