The polymorphism at position beta69 of the human leukocyte antigen (HLA)-DP molecule has been associated with susceptibility to several immune disorders and alloreactivity. Using molecular modeling, we have predicted a detailed structure of the HLA-DP2 molecule (carrying Glubeta69) complexed with class II associated invariant chain derived peptide (CLIP)(More)
BACKGROUND Human influenza virus isolates generally grow poorly in embryonated chicken eggs. Hence, gene reassortment of influenza A wild type (wt) viruses is performed with a highly egg adapted donor virus, A/Puerto Rico/8/1934 (PR8), to provide the high yield reassortant (HYR) viral 'seeds' for vaccine production. HYR must contain the hemagglutinin (HA)(More)
BACKGROUND Androgen receptor (AR) gene mutations are the most frequent cause of 46,XY disorders of sex development (DSD) and are associated with a variety of phenotypes, ranging from phenotypic women [complete androgen insensitivity syndrome (CAIS)] to milder degrees of undervirilization (partial form or PAIS) or men with only infertility (mild form or(More)
Berylliosis is a chronic granulomatous disorder caused by inhalation of Be dusts that is driven by the accumulation of Be-specific CD4+ Th1-cells at disease sites. Susceptibility to berylliosis has been associated with the supratypic variant of HLA-DP gene coding for glutamate at position beta69 (HLA-DPbetaGlu69). The aim of this study was to test the(More)
BACKGROUND Influenza A virus vaccines undergo yearly reformulations due to the antigenic variability of the virus caused by antigenic drift and shift. It is critical to the vaccine manufacturing process to obtain influenza A seed virus that is antigenically identical to circulating wild type (wt) virus and grows to high titers in embryonated chicken eggs.(More)
β-Adrenergic receptor blockade reduces total mortality and all-cause hospitalizations in patients with heart failure (HF). Nonetheless, β-blockade does not halt disease progression, suggesting that cAMP-dependent protein kinase (PKA) signaling downstream of β-adrenergic receptor activation may persist through unique post-translational states. In this study,(More)
Increasing evidence supports that many common obstetrical complications may involve the disruption of normal placental and/or uterine vascular function. Placenta growth factor (PlGF) is an angiogenic factor that is abundantly expressed in the placenta, with primary site of synthesis being trophoblast. Receptors for PlGF include products of the fms-like(More)
A 2-year-old girl with sporadic unilateral Wilms' tumor (WT) not associated with aniridia was found to have, besides other chromosome abnormalities, a t(2;7)(q33;p22) in 6% of her lymphocytes. A comparison with 7 previous WT cases without aniridia in whom diverse chromosomal aberrations were present, reveals a wide heterogeneity and lead us to tentatively(More)
