Narrare la malattia. Un modello gnoseologico a partire dalle «Confessioni di un italiano»

Gli argomenti riferiti al mondo della medicina nel capolavoro di Nievo sono parti di un modello gnoseologico sviluppato nel romanzo. Negli aspetti narratologici che coinvolgono i personaggi e le sequenze si individuano riflessioni di argomento etico sulle dinamiche che reggono la società. Negli aspetti descrittivi ed in quelli riferiti alle componenti retoriche, semantiche e morfosintattiche, si rivelano interazioni di tipo costruttivista a cui corrisponde la descrizione di alcune patologie in cui si tratteggiano interazioni che anticipano le dinamiche dei neurotrasmettitori.The medical elements in Nievo’s masterpiece are the bricks of a gnoseological model. On the narrative level the character are mdium of some sequence to build the ethical reflection about society. On the level of semantic argouments – that through characters – there are some descriptions of sickness where it form a metaphore as the same as the dynamics of cells, neurons and glial cells, some times before the medical discveries of expert

Multidimensional Functional Profiling of Human Neuropathogenic FOXG1 Alleles in Primary Cultures of Murine Pallial Precursors

FOXG1 is an ancient transcription factor gene mastering telencephalic development. A number of distinct structural FOXG1 mutations lead to the “FOXG1 syndrome”, a complex and heterogeneous neuropathological entity, for which no cure is presently available. Reconstruction of primary neurodevelopmental/physiological anomalies evoked by these mutations is an obvious pre-requisite for future, precision therapy of such syndrome. Here, as a proof-of-principle, we functionally scored three FOXG1 neuropathogenic alleles, FOXG1G224S, FOXG1W308X, and FOXG1N232S, against their healthy counterpart. Specifically, we delivered transgenes encoding for them to dedicated preparations of murine pallial precursors and quantified their impact on selected neurodevelopmental and physiological processes mastered by Foxg1: pallial stem cell fate choice, proliferation of neural com-mitted progenitors, neuronal architecture, neuronal activity, and their molecular correlates. Briefly, we found that FOXG1G224S and FOXG1W308X generally performed as a gain-and a loss-of-function-allele, respectively, while FOXG1N232S acted as a mild loss-of-function-allele or phenocopied FOXG1WT . These results provide valuable hints about processes misregulated in patients heterozygous for these mutations, to be re-addressed more stringently in patient iPSC-derivative neuro-organoids. Moreover, they suggest that murine pallial cultures may be employed for fast multidimensional profiling of novel, human neuropathogenic FOXG1 alleles, namely a step propedeutic to timely delivery of therapeutic precision treatments
