| E.2.2 | Secondary objectives of the trial  | 
| (i) to identify novel mechanisms of regulation and function of microglia under various conditions (inflammatory  stimuli; neurodegenerative and -regenerative model systems);  (ii) to identify and implement new targets for activated microglia, which may serve for diagnostic (imaging) and  therapeutic purposes;  (iii) to design new molecular probes (tracers) for these novel targets and to implement and validate them in in  vivo model systems and patients;  (iv) to image and quantify modulated microglia activity in patients undergoing immune therapy for cognitive  impairment and relate findings to clinical outcome. | 
 
| (i) identificare nuovi meccanismi di regolazione e la funzione della microglia in varie condizioni (stimoli infiammatori, sistemi modello di tipo neurodegenerativo e rigenerativo);  (ii) individuare ed implementare nuovi obiettivi per la microglia attivata, che possano essere utili per la diagnostica (imaging) e a fini terapeutici;  (iii) progettare per questi obiettivi nuovi nuovi traccianti da validare in  sistemi modello in vivo e nei pazienti;  (iv) quantificare l'attività modulata della microglia in pazienti sottoposti a terapia immunitaria per peggioramento cognitivo e correlati di esito clinico |
