Rapamycin modulates pulmonary pathology in a murine model of Mycobacterium tuberculosis infection.

Disease models & mechanisms

Tuberculosis (TB) treatment regimens are lengthy, causing non-adherence to treatment. Inadequate treatment can lead to relapse and the development of drug resistance TB. Furthermore, patients often exhibit residual lung damage even after cure, increasing the risk for relapse and...

Mammalian Atg8-family proteins are upstream regulators of the lysosomalsystem by controlling MTOR and TFEB.

Autophagy

Macroautophagy/autophagy delivers cytoplasmic cargo to lysosomes for degradation. In yeast, the single Atg8 protein plays a role in the formation of autophagosomes whereas in mammalian cells there are five to seven paralogs, referred to as mammalian Atg8s (mAtg8s: GABARAP,...

Mammalian hybrid pre-autophagosomal structure HyPAS generates autophagosomes.

The biogenesis of mammalian autophagosomes remains to be fully defined. Here, we used cellular and in vitro membrane fusion analyses to show that autophagosomes are formed from a hitherto unappreciated hybrid membrane compartment. The autophagic precursors emerge through fusion...

Atg8ylation as a general membrane stress and remodeling response.

Cell stress

The yeast Atg8 protein and its paralogs in mammals, mammalian Atg8s (mAtg8s), have been primarily appreciated for their participation in autophagy. However, lipidated mAtg8s, including the most frequently used autophagosomal membrane marker LC3B, are found on cellular membranes other...

A master conductor for aggregate clearance by autophagy.

Autophagic adapters including p62/SQSTM1 recognize polyubiquitinated targets such as toxic protein aggregates. In a recent issue of Molecular Cell, Filimonenko et al. provide evidence that the phosphatidylinositol 3-phosphate (PI3P) binding protein, Alfy, interacts with p62, Atg5, and PI3P to...

Autophagy of intracellular microbes and mitochondria: two sides of the same coin?.

Autophagy has become a biological paradigm of how eukaryotic cells, especially those that are long lived, maintain their vitality, control the quality of cytoplasmic organelles, and stay alive or die when growth factors are withdrawn and there is an...
