Abstract
Autophagy is a tightly regulated pathway involving the lysosomal degradation of cytoplasmic organelles or cytosolic components. This pathway can be stimulated by multiple forms of cellular stress, including nutrient or growth factor deprivation, hypoxia, reactive oxygen species, DNA damage, protein aggregates, damaged organelles, or intracellular pathogens. Both specific, stimulus-dependent and more general, stimulus-independent signaling pathways are activated to coordinate different phases of autophagy. Autophagy can be integrated with other cellular stress responses through parallel stimulation of autophagy and other stress responses by specific stress stimuli, through dual regulation of autophagy and other stress responses by multifunctional stress signaling molecules, and/or through mutual control of autophagy and other stress responses. Thus, autophagy is a cell biological process that is a central component of the integrated stress response.

TRAPP complexes in membrane traffic: convergence through a common Rab.
TRAPP复合物在膜转运中作用：收敛通过共同的Rab

Abstract
Transport protein particle (TRAPP; also known as trafficking protein particle), a multimeric guanine nucleotide-exchange factor for the yeast GTPase Ypt1 and its mammalian homologue, RAB1, regulates multiple membrane trafficking pathways. TRAPP complexes exist in three forms, each of which activates Ypt1 or RAB1 through a common core of subunits and regulates complex localization through distinct subunits. Whereas TRAPPI and TRAPPII tether coated vesicles during endoplasmic reticulum to Golgi and intra-Golgi traffic, respectively, TRAPPIII has recently been shown to be reqiured for autophagy. These advances illustrate how the TRAPP complexes link Ypt1 and RAB1 activation to distinct membrane-tethering events.
