Autophagy is a cellular process that allows degradation by the lysosome of cytoplasmic components such as proteins or organelles. Many studies that used model organisms, showed that autophagy plays an important role in multiple developmental processes like degradation of mitochondria of spermatozoids after fertilization, fetal growth or resistance to nutrient starvation. It is also essential to programmed cell death. The involvement of autophagy in these processes may be related to the production of energy resources in conditions of stress or autophagy can selectively degrade specific proteins during development.

Macroautophagy/autophagy is an evolutionarily conserved process through which cells degrade cytoplasmic substances via autophagosomes. During the initiation of autophagosome formation, the ULK/Atg1 complex serves as a scaffold that recruits and regulates downstream ATG/Atg proteins and ATG9/Atg9-containing vesicles. Despite the essential role of the ULK/Atg1 complex, its components have changed during evolution; the ULK complex in mammals consists of ULK1 (or ULK2), RB1CC1, ATG13, and ATG101, whereas the Atg1 complex in the yeast lacks Atg101 but instead has Atg29 and Atg31 along with Atg17.

Endothelial Colony-Forming Cells (ECFCs) are recognized as key vasculogenic progenitors in humans and serve as valuable liquid biopsies for diagnosing and studying vascular disorders. In a groundbreaking study, Anceschi et al. present a novel, integrative strategy that combines ECFCs loaded with gold nanorods (AuNRs) to enhance tumor radiosensitization through localized hyperthermia.

Dysregulated spine morphology is a common feature in the pathology of many neurodevelopmental and neuropsychiatric disorders. Overabundant immature dendritic spines in the hippocampus are causally related to cognitive deficits of Fragile X syndrome (FXS), the most common form of heritable intellectual disability. Recent findings from us and others indicate autophagy plays important roles in synaptic stability and morphology, and autophagy is downregulated in FXS neurons.

Cystic fibrosis (CF) is a genetic disorder primarily known for its severe impact on lung function, but it also significantly affects the digestive system, leading to complications such as intestinal blockages, malabsorption, inflammation, and microbial dysbiosis. The study of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) effects on intestinal physiology is critical for developing new effective treatments. This work highlights the use of the mouse intestine as a valuable model for analyzing cellular electrophysiology and CFTR function.
