Early life, covering childhood and adolescence in humans, is an important period of brain development and maturation. Experimental works in rodents have shown that high-caloric diets are particularly detrimental to young rats, affecting cognition. We studied the effects of two different high-caloric diets, prevalent in human adolescents, on male Wistar rats aged 4 weeks at the beginning of the experiment. Rats were randomly allocated to control (C, n = 10), high-sugar diet (HS, n = 10) and cafeteria diet (CAF, n = 10) groups and fed accordingly for 8 weeks. At the end of this period, behavioral tests were performed to analyze (1) anxiety behavior in the elevated plus-maze and open field tests, (2) learning and memory processes in the Morris water maze and novel object recognition test, (3) fear response in the fear conditioning test, and (4) depression state in the forced swim test. We also examined neurogenesis in the dentate gyrus using the marker of neuroproliferation doublecorti...

Under the Maastricht Treaty, the introduction of data protection rules in EU freedom, security, and justice instruments was justified by the pillars structure. A new EU competence regulating personal data protection and its free movement enabled overcoming the reticence about framing the processing activities for police and judicial cooperation in criminal matters. Despite adopting the law enforcement directive, Europol maintained a distinct regulation until regulation 2022/991 aligned its mandate with the EU data protection regulation (EUDPR). These amendments faced the European Data Protection Supervisor’s criticism for departing from the horizontal standards set down in the EUDPR, Chapter IX. This paper highlights legal uncertainty over fragmented legal frameworks on personal data protection in the EU and clarifies their relationships, stressing the importance of coherence among Union policies, while taking the Europol’s big data challenge episode under scrutiny.

Anti-glomerular basement membrane (anti-GBM) disease is characterized by antibodies and T cells directed against the Goodpasture antigen, the noncollagenous domain of the α3-chain of type IV collagen [α3(IV)NC1] of the GBM. Consequences are the deposition of autoantibodies along the GBM and the development of crescentic glomerulonephritis (GN) with rapid loss of renal function. Forkhead box protein P3 (Foxp3)+regulatory T (Treg) cells are crucial for the maintenance of peripheral tolerance to self-antigens and the prevention of immunopathology. Here, we use the mouse model of experimental autoimmune GN to characterize the role of Treg cells in anti-GBM disease. Immunization of DBA/1 mice with α3(IV)NC1 induced the formation of α3(IV)NC1-specific T cells and antibodies and, after 8–10 wk, the development of crescentic GN. Immunization resulted in increased frequencies of peripheral Treg cells and renal accumulation of these cells in the stage of acute GN. Depletion of Treg cells duri...
