Graves' Ophthalmopathy (GO) is a complex eye and orbital disorder that is uniquely linked to Graves' Hyperthyroidism (GH) and has traditionally been considered a cross-reactive immune response against the thyroid stimulating hormone receptor (TSHR) in orbital tissue. However, because there is no direct evidence, such as specific TSHR antibodies or T lymphocytes targeting the orbital tissues in patients with GO compared to those without eye disease, it is important to consider alternative hypotheses for the pathogenesis of GO. The aim of this study was to identify differentially expressed genes within the thyroid of patients with GO and GH as a possible explanation for a thyroid initiated orbital autoimmunity.

Replication-defective adenovirus vectors, primarily developed from serotype 5 (Ad5) viruses, have been widely used for gene transfer and vaccination approaches. Vectors based on other serotypes of adenovirus could be used in conjunction with, or in place of, Ad5 vectors. In this study, Ad41, an enteric adenovirus usually described as 'non-cultivable' or 'fastidious,' has been successfully cloned, rescued and propagated on 293-ORF6 cells. The complementation capabilities of this cell line allow generation of Ad41 vectors at titers comparable to those obtained for Ad5 vectors. Mice immunized with an Ad41 vector containing an HIV envelope (Env) gene mounted anti-Env cellular and humoral immune responses. Ad41-Env vectors appear to be particularly attractive when used in heterologous prime-boost regimens, where they induce significantly higher cellular immune responses to HIV-Env than Ad5-based regimens. Ad41-based constructs are attractive vaccine vectors alone or in combination with Ad5 adenovectors, since each vector type can provide circumvention of pre-existing immunity to the other.
