t al.Fast signaling from vision and proprioception to muscle activation plays essential roles in quickly correcting movement. Though many studies have demonstrated modulation of the quick sensorimotor responses as depending on context in each modality, the contribution of multimodal information has not been established. Here, we examined whether state estimates contributing to stretch reflexes are represented solely by proprioceptive information or by multimodal information. Unlike previous studies, we newly found a significant stretch-reflex attenuation by the distortion and elimination of visual-feedback without any change in motor tasks. Furthermore, the stretch-reflex amplitude reduced with increasing elimination durations which would degrade state estimates. By contrast, even though a distortion was introduced in the target-motor-mapping, the stretch reflex was not simultaneously attenuated with visuomotor reflex. Our results therefore indicate that the observed stretch-reflex attenuation is specifically ascribed to uncertainty increase in estimating hand states, suggesting multimodal contributions to the generation of stretch reflexes. © 2020, Ito and Gomi.Current xenogeneic mouse models cannot evaluate on-target off-tumor adverse effect, hindering the development of chimeric antigen receptor (CAR) T cell therapies for solid tumors, due to limited human/mouse cross-reactivity of antibodies used in CAR and sever graft-versus-host disease induced by administered human T cells. We have evaluated safety and antitumor efficacy of CAR-T cells targeting glypican-1 (GPC1) overexpressed in various solid tumors. GPC1-specific human and murine CAR-T cells generated from our original anti-human/mouse GPC1 antibody showed strong antitumor effects in xenogeneic and syngeneic mouse models, respectively. Importantly, the murine CAR-T cells enhanced endogenous T cell responses against a non-GPC1 tumor antigen through the mechanism of antigen-spreading and showed synergistic antitumor effects with anti-PD-1 antibody without any adverse effects in syngeneic models. Our study shows the potential of GPC1 as a CAR-T cell target for solid tumors and the importance of syngeneic and xenogeneic models for evaluating their safety and efficacy. © 2020, Kato et al.A new company is offering extensive genetic analysis of embryos during an in vitro fertilisation procedure, allowing the derivation of polygenic scores for several diseases and embryo choice based on these results. Polygenic scores, if properly implemented, can indeed have substantial predictive value, and the possibility of embryo choice based on these data has become real, raising a number of practical and ethical problems. ‡. © 2020 médecine/sciences – Inserm.in French Title Les biobanques, des structures essentielles à la recherche médicale. Abstract Le Master Biobanks and Complex Data Management forme les managers des biobanques. Créé en 2017 à l’Université Côte d’Azur par le Professeur Paul Hofman, ce master prépare les étudiants au management des biobanques (humaines, animales, plantes et autres organismes vivants) et des données complexes. Au-delà du stockage des collections d’échantillons biologiques, il faut en assurer la qualité, la conservation, la disponibilité auprès des réseaux de chercheurs en respectant la législation et l’éthique. Les enseignements du master se partagent entre les compétences disciplinaires en qualité, hygiène et sécurité, réglementation, bioéthique, biobankonomics et les enseignements techniques réalisés à la biobanque du CHU de Nice, puis mis en pratique lors de deux stages de 6 mois.in French Title Les laboratoires ouverts Tous Chercheurs. Abstract L’enjeu d’une culture scientifique pour tous est d’importance face à la difficulté des citoyens à critiquer les données de la science avec des arguments rationnels, notamment en ce qui concerne la biologie et la santé (vaccination, procréation médicalement assistée, etc.), car le grand public ne veut plus
