Bacterial interaction with host autophagy.

Summary of "Bacterial interaction with host autophagy."

Autophagy is a conserved and fundamental cellular process mainly to recycle or eliminate dysfunctional cellular organelles or proteins. As a response to cellular stress, autophagy is used as a defense mechanism to combat the infection with pathogenic bacteria. However, many intracellular bacteria have developed diverse mechanisms to evade recognition, to manipulate the autophagic pathway, and to hijack the autophagosomal compartment for replication. In this review, we discuss recent understandings on how bacteria interact with host autophagy.

Medical and Biotech [MESH] Definitions

Bacterial proteins that are used by BACTERIOPHAGES to incorporate their DNA into the DNA of the "host" bacteria. They are DNA-binding proteins that function in genetic recombination as well as in transcriptional and translational regulation.

Proteins and enzymes that function, often as components of MULTIPROTEIN COMPLEXES, to assemble AUTOPHAGOSOMES and carry out AUTOPHAGY.

An autophagy related protein that is similar to UBIQUITIN-ACTIVATING ENZYME E1. It functions in CYTOPLASM to VACUOLE transport (Cvt) and AUTOPHAGY by activating ATG12 PROTEIN for its conjugation with ATG5 PROTEIN, as well as the conjugation of ATG8 FAMILY PROTEINS with phosphatidylethanolamine for ATG8 association to Cvt vesicles and AUTOPHAGOSOME membranes. It is also required for the nitrogen starvation response in yeast, MITOPHAGY; and autophagic cell death induced by CASPASE 8 inhibition.

An integration host factor that was originally identified as a bacterial protein required for the integration of bacteriophage Q beta (ALLOLEVIVIRUS). Its cellular function may be to regulate mRNA stability and processing in that it binds tightly to poly(A) RNA and interferes with ribosome binding.

Changes in quantitative and qualitative composition of MICROBIOTA. The changes may lead to altered host microbial interaction or homeostatic imbalance that can contribute to a disease state often with inflammation.
