Compared with the MHC of typical mammals, the chicken MHC is smaller and simpler, with only two class I genes found in the B12 haplotype. We make five points to show that there is a single-dominantly expressed class I molecule that can have a strong effect on MHC function. First, we find only one cDNA for two MHC haplotypes (B14 and B15) and cDNAs(More)
Little is known about the structure of major histocompatibility complex (MHC) molecules outside of mammals. Only one class I molecule in the chicken MHC is highly expressed, leading to strong genetic associations with infectious pathogens. Here, we report two structures of the MHC class I molecule BF2*2101 from the B21 haplotype, which is known to confer(More)
OBJECTIVE Some longitudinal magnetic resonance imaging (MRI) studies have shown reduced volume or cortical thickness (CT) in the frontal cortices of individuals with attention-deficit/hyperactivity disorder (ADHD). These studies indicated that the aforementioned anatomical abnormalities disappear during adolescence. In contrast, cross-sectional studies on(More)
In mammals, there are MHC class II molecules with distinctive sequence features, such as the classical isotypes DR, DQ and DP. These particular isotypes have not been reported in non-mammalian vertebrates. We have isolated the class II (B-L) α chain from outbred chickens as the basis for the cloning and sequencing of the cDNA. We found only one class II α(More)
Biomarkers are the only feasible way to detect and monitor presymptomatic Alzheimer's disease (AD). No single biomarker can predict future cognitive decline with an acceptable level of accuracy. In addition to designing powerful multimodal diagnostic platforms, a careful investigation of the major sources of disease heterogeneity and their influence on(More)
INTRODUCTION The current literature on facial attractiveness focuses on anterior-posterior facial portraits, with lateral facial analysis limited to comparing facial attractiveness scores with various facial measurements. Here we use a novel approach to more rigorously study lateral facial attractiveness by combining morphing software and a genetic(More)
In recent years, short coiled coils have been used for applications ranging from biomaterial to medical sciences. For many of these applications knowledge of the factors that control the topology of the engineered protein systems is essential. Here, we demonstrate that trimerization of short coiled coils is determined by a distinct structural motif that(More)
J chain is a small polypeptide covalently attached to polymeric IgA and IgM. In humans and mice, it plays a role in binding Ig to the polymeric Ig receptor for transport into secretions. The putative orthologue of mammalian J chain has been identified in the nurse shark by sequence analysis of cDNA and the polypeptide isolated from IgM. Conservation with J(More)
BACKGROUND The goal of this study was to identify a clinical biomarker signature of brain amyloidosis in the Alzheimer's Disease Neuroimaging Initiative 1 (ADNI1) mild cognitive impairment (MCI) cohort. METHODS We developed a multimodal biomarker classifier for predicting brain amyloidosis using cognitive, imaging, and peripheral blood protein ADNI1 MCI(More)
A number of antibodies have been developed that induce lethal iron deprivation (LID) by targeting the transferrin receptor 1 (TfR1/CD71) and either neutralizing transferrin (Tf) binding, blocking internalization of the receptor and/or inducing its degradation. We have developed recombinant antibodies targeting human TfR1 (ch128.1 and ch128.1Av), which(More)
