Artículo de revista ; The impact of COVID-19 represents an unprecedented international challenge and the most severe test of the resilience of the banking industry – and of the financial system as a whole – since the global financial crisis of 2008. The rapid and resolute response of international and European Union institutions and fora with financial regulatory and supervisory responsibilities has been aimed to coordinate the actions taken at national level and, thus, to help safeguard the orderly functioning and stability of the financial system, as well as the uninterrupted financing of the real economy. This response has spanned different areas, including microprudential, accounting and macroprudential policies. This article provides an overview of the standards, guidelines and measures promoted since March 2020 by different authorities. The wide-ranging regulatory and supervisory reaction to COVID-19 is emerging as a distinctive feature of the management of this crisis, which, far from over, has led to an environment of heightened uncertainty and risks for the financial system which warrants further monitoring and a continued policy response.

Interferon gamma (IFNγ) has somewhat controversially been associated with SVZ progenitor proliferation and neurogenesis. The in vivo involvement of IFNγ in the physiology of the adult SVZ niche is not fully understood and its intracellular mediators are unknown. Here we show that IFNγ, through activation of its canonical signal transducer and activator of transcription 1 (STAT1) pathway, acts specifically on Nestin+ progenitors by decreasing both progenitor proliferation and the number of cycling cells. In addition, IFNγ increases the number of neuroblasts generated without shifting glial fate determination. The final result is deficient recruitment of newborn neurons to the olfactory bulb (OB), indicating that IFNγ-induced stimulation of neuronal differentiation does not compensate for its antiproliferative effect. We conclude that IFNγ signaling via STAT1 in the SVZ acts dually as an antiproliferative and proneurogenic factor, and thereby regulates neurogenesis in normal adult brains. ; This work was supported by the Marató TV3, and a Mapfre foundation award to EP, and Spanish Ministry of Economy MINECO (SAF2014-56279-R) to AMP.
