- In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

- <b><i>Background/Aims:</i></b> National Plans for Rare Diseases (RDs) are the common denominator of current public health policy concerns on RDs across the EU. With the aim of a better distribution of the available resources, they conjugate the European objective that aims at ensuring that patients with RDs have access to high-quality care - including diagnostics, treatment and rehabilitation - with the national priorities of selecting specific measures for adoption and implementation. <b><i>Methods:</i></b> The European Project for Rare Diseases National Plans Development (EUROPLAN, www.europlanproject.eu) is cofunded by the EU Commission (DG-SANCO) and is coordinated by the Italian National Center for Rare Diseases of the Istituto Superiore di Sanità (ISS). The EUROPLAN goal is to promote the implementation of National Plans or Strategies to tackle RDs and share relevant experiences within countries, linking national efforts, through a common strategy at a European level. In order to fulfill these objectives, EUROPLAN involved health authorities, clinicians, scientists, the European Organisation for Rare Diseases (EURORDIS), and many other patient groups as associated and collaborating partners from several European countries. <b><i>Results:</i></b> The project was launched in 2008 and foresaw 2 implementation phases: phase 1 (2008-2011) to build the consensus definition of operational tools (recommendations and indicators), and the ongoing phase 2 (2012-2015), mainly aimed at capacity building with the proactive involvement of multilevel stakeholders. EUROPLAN is facilitating and accelerating the implementation of National Plans in almost all EU and several non-EU Countries. <b><i>Conclusions:</i></b> EUROPLAN is a European and an international process more than a project, and it could be defined as a ‘litmus test' demonstrating how the collaboration between institutions and patients' associations can accelerate the process of awareness and development of policies and actions.
