Abstract
Deposits of different abnormal forms of tau in neurons and astrocytes represent key anatomo-pathological features of tauopathies. Although tau protein is highly enriched in neurons and poorly expressed by astrocytes, the origin of astrocytic tau is still elusive. Here, we used innovative gene transfer tools to model tauopathies in adult mouse brains and to investigate the origin of astrocytic tau. We showed in our adeno-associated virus (AAV)-based models and in Thy-Tau22 transgenic mice that astrocytic tau pathology can emerge secondarily to neuronal pathology. By designing an in vivo reporter system, we further demonstrated bidirectional exchanges of tau species between neurons and astrocytes. We then determined the consequences of tau accumulation in astrocytes on their survival in models displaying various status of tau aggregation. Using stereological counting of astrocytes, we report that, as for neurons, soluble tau species are highly toxic to some subpopulations of astrocytes in the hippocampus, whereas the accumulation of tau aggregates does not affect their survival. Thus, astrocytes are not mere bystanders of neuronal pathology. Our results strongly suggest that tau pathology in astrocytes may significantly contribute to clinical symptoms.

Abstract
Articular cartilage repair after injury is a great challenge worldwide due to its nerveless and avascular features. Tissue engineering is proposed as a promising alternative for cartilage regeneration. In this study, an adenoviral vector carrying the transforming growth factor-β3 (TGF-β3) gene was constructed and introduced into dedifferentiated chondrocytes, which were then cocultured with ATDC5 cells in an alginate hydrogel system. The results showed that the experimental groups exhibited better cell viability and higher levels of cartilage-related genes than the control groups. In this coculture system, the chondrogenic differentiation of ATDC5 cells was effectively induced by TGF-β3 and other latent cytokines that were produced by the transfected chondrocytes. Thus, this method can avoid the degradation of exogenous TGF-β3, and it can protect ATDC5 cells during virus transfection to maintain cell viability and chondrogenic differentiation capability. Taken together, this study provides fresh insights for applying this genetically manipulated coculture system to cartilage repair in the future.

Abstract
Tauopathies are neurodegenerative diseases characterized by the aggregation of tau protein. These pathologies exhibit a wide variety of clinical and anatomo-pathological presentations, which may result from different pathological mechanisms. Although tau inclusions are a common feature in all these diseases, recent evidence instead implicates small oligomeric aggregates as drivers of tau-induced toxicity. Hence in vivo model systems displaying either soluble or fibrillary forms of wild-type or mutant tau are needed to better identify their respective pathological pathways. Here we used adeno-associated viruses to mediate gene transfer of human tau to the rat brain to develop models of pure tauopathies. Two different constructs were used, each giving rise to a specific phenotype developing in less than 3 months. First, hTAUWT overexpression led to a strong hyperphosphorylation of the protein, which was associated with neurotoxicity in the absence of any significant aggregation. In sharp contrast, its co-expression with the pro-aggregation peptide TauRD-ΔK280 in the hTAUProAggr group strongly promoted its aggregation into Gallyas-positive neurofibrillary tangles, while preserving neuronal survival. Our results support the hypothesis that soluble tau species are key players of tau-induced neurodegeneration.
