In this Issue: Nef, A Lingering Problem; Are There Better Immunoglobulins for Human Use; and Takayasu Arteritis, Still a Mystery

Abstract

The current issue of the International Reviews of Immunology brings the latest in three different areas of basic and clinical immunology. First, there is the lingering question of residual HIV-related pathology in patients on chronic antiretroviral therapy. The specific role of Nef in the macrophage-mediated disease manifested through lymphoma, metabolic disease and neurological disorder, is extensively discussed. A second topic is a clinical immunology one, a critical perspective on the efficacy and safety profile of various preparations of immunoglobulin products currently prescribed for a range of immunodeficiencies. Surprisingly, the authors showed that while the available preparations are equivalent from efficacy standpoint, they differ from the standpoint of toxicity. The third subject is again, in the arena of clinical immunology and deals with a relatively rare yet extremely puzzling disease –Takayasu arteritis –with a pathogenesis that needs elucidation and a dire need for better treatments. The authors provide a state of the art in terms of genetic association, other factors possibly involved in the onset and progression of this unusual inflammatory disease of large arteries, and provide a perspective on current standard of care and potential usefulness of TNF-α blockade as therapy for Takayasu arteritis.
