The E3 ubiquitin ligase SIAH1 targets a bacterial pore-forming toxin to facilitate xenophagy

Cell Reports
Summary: Xenophagy, one form of selective autophagy, recognizes and eliminates the invading pathogen through the ubiquitination of bacterial surface components.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Xenophagy receptors Optn and p62 and autophagy modulator Dram1 independently promote the zebrafish host defense against Mycobacterium marinum

Frontiers in Cellular and Infection Microbiology
Anti-bacterial autophagy, also known as xenophagy, is a crucial innate immune process that helps maintain cellular homeostasis by targeting invading microbes.

Selective Autophagy Receptor CsNBR1 Confers Citrus Huanglongbing Resistance by Degrading ‘Candidatus Liberibacter Asiaticus’ Virulence Effectors

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
Overexpression of CsNBR1 confers HLB resistance in citrus by degrading CLas effector proteins, including SDE5115, SDE1, SDE19 and SDE5, via the autophagy pathway. ABSTRACT The selective autophagy receptor NEIGHBOUR OF BRCA1 (NBR1) is a key regulator of plant immunity, but its role against bacterial pathogens remains poorly understood.

The Role of Autophagy in Crohn’s Disease

Cells, 2012
(Macro)-autophagy is a homeostatic process by which eukaryotic cells dispose of protein aggregates and damaged organelles. Autophagy is also used to degrade micro-organisms that invade intracellularly in a process termed xenophagy.

Borrelia burgdorferi sensu lato Employs Several Escape Mechanisms to Bypass the Human Defense System

European Journal of Immunology, Volume 56, Issue 5, May 2026.
Integrated overview of host defense and immune evasion in Lyme Borreliosis. Bbsl evades immunity through tick saliva‐mediated suppression of innate defenses, TLR2/NOD2‐driven cytokine dysregulation, and interference with JAK/STAT and CIITA‐dependent antigen presentation.

TBK1 kinase addiction in lung cancer cells is mediated via autophagy of Tax1bp1/Ndp52 and non-canonical NF-κB signalling.

PLoS ONE, 2012
K-Ras dependent non-small cell lung cancer (NSCLC) cells are 'addicted' to basal autophagy that reprograms cellular metabolism in a lysosomal-sensitive manner.

Newly identified properties of known pharmaceuticals and myxobacterial small molecules revealed by screening for autophagy modulators

The FEBS Journal, Volume 293, Issue 8, Page 2314-2340, April 2026.
Autophagy is a cellular degradation process involved in, for example, immune responses to pathogens and neurodegeneration. To identify modulators of autophagy, we developed a microscopy‐based screening assay and identified previously unknown autophagy‐modulating activities in known drugs and natural products from myxobacteria and fungi.

Xenophagy: A battlefield between host and microbe, and a possible avenue for cancer treatment [PDF]

Autophagy, 2016
In eukaryotes, xenophagy is defined as a type of selective macroautophagy/autophagy that is used for eliminating invading pathogens. In contrast to other types of selective autophagy, such as mitophagy, pexophagy and ribophagy, xenophagy is used by eukaryotes for targeting microbes-hence the prefix "xeno" meaning "other" or "foreign"-that have infected

Regulation of autophagy‐mediated pathways by diet, physical activity, and sleep in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract Alzheimer's disease (AD) is a progressive, age‐related, neurodegenerative disorder marked by cognitive decline, memory loss, and accumulation of amyloid beta (Aβ) plaques and tau tangles. A key feature of AD is impaired protein homeostasis, often driven by autophagy dysfunction.
