Over time, riding techniques and the style of riding improved. Therefore, horses with the ability to perform comfortable gaits (e.g. ambling or pacing), so-called ‘gaited’ horses, have been highly valued by humans, especially for long distance travel. Recently, the causative mutation for gaitedness in horses has been linked to a substitution causing a premature stop codon in the DMRT3 gene (DMRT3_Ser301STOP) [1]. In mice, Dmrt3 is expressed in spinal cord interneurons and plays an important role in the development of limb movement coordination [1]. Genotyping the position in 4396 modern horses from 141 breeds revealed that nowadays the mutated allele is distributed worldwide with an especially high frequency in gaited horses and breeds used for harness racing [2]. Here, we examine historic horse remains for the DMRT3 SNP, tracking the origin of gaitedness to Medieval England between 850 and 900 AD. The presence of the corresponding allele in Icelandic horses (9th–11th century) strongly suggests that ambling horses were brought from the British Isles to Iceland by Norse people. Considering the high frequency of the ambling allele in early Icelandic horses, we believe that Norse settlers selected for this comfortable mode of horse riding soon after arrival. The absence of the allele in samples from continental Europe (including Scandinavia) at this time implies that ambling horses may have spread from Iceland and maybe also the British Isles across the continent at a later date.

In order to circumvent the consisting drawbacks an in vitro immunization approach was established by which murine as well as human monoclonal antibodies against a viral coat protein could be developed. The in vitro immunization process was performed by isolation of murine hematopoietic stem cells or human monocytes and an in vitro differentiation into immature dendritic cells. After antigen loading the cells were co-cultivated with naive T and B lymphocytes for three days in order to obtain antigen-specific B lymphocytes in culture, followed by fusion with murine myeloma cells or human/murine heteromyeloma cells. Antigen-specific hybridomas were selected and the generated antibodies were purified and characterized in this study by ELISA, western blot, gene sequencing, affinity measurements. Further the characteristics were compared to a monoclonal antibody against the same target generated by conventional hybridoma technology. Isotype detection revealed a murine IgM and a human IgG4 antibody in comparison to an IgG1 for the conventionally generated antibody. The antibodies derived from in vitro immunization showed indeed a lower affinity for the antigen as compared to the conventionally generated one, which is probably based on the significantly shorter B cell maturation (3 days) during the immunization process. Nevertheless, they were suitable for building up a sandwich based detection system. Therefore, the in vitro immunization approach seems to be a good and particularly fast alternative to conventional hybridoma technology.

Proceedings of the 23rd Aschauer Soiree, Held at Aschauhof, Germany, November 7th 2015 T2 - Pediatric Endocrinology Reviews N2 - Twenty-four scientists met at Aschauhof, Altenhof, Germany, to discuss the associations between child growth and development, and nutrition, health, environment and psychology. Meta-analyses of body height, height variability and household inequality, in historic and modern growth studies published since 1794, highlighting the enormously flexible patterns of child and adolescent height and weight increments throughout history which do not only depend on genetics, prenatal development, nutrition, health, and economic circumstances, but reflect social interactions. A Quality of Life in Short Stature Youth Questionnaire was presented to cross-culturally assess health-related quality of life in children. Changes of child body proportions in recent history, the relation between height and longevity in historic Dutch samples and also measures of body height in skeletal remains belonged to the topics of this meeting. Bayesian approaches and Monte Carlo simulations offer new statistical tools for the study of human growth.

It was discussed recently that a long and a short isoform of GP2 exists whereas the short isoform is often detected by GP2-specific autoantibodies. In the outcome of inflammatory bowel diseases, these GP2-specific autoantibodies are discussed as new serological markers for diagnosis and therapeutic monitoring. To investigate this further, camelid nanobodies were generated by phage display and selected against the short isoform of GP2 in order to isolate specific tools for the discrimination of both isoforms. Nanobodies are single domain antibodies derived from camelid heavy chain only antibodies and characterized by a high stability and solubility. The selected candidates were expressed, purified and validated regarding their binding properties in different enzyme-linked immunosorbent assays formats, immunofluorescence, immunohistochemistry and surface plasmon resonance spectroscopy. Four different nanobodies could be selected whereof three recognize the short isoform of GP2 very specifically and one nanobody showed a high binding capacity for both isoforms. The KD values measured for all nanobodies were between 1.3 nM and 2.3 pM indicating highly specific binders suitable for the application as diagnostic tool in inflammatory bowel disease.
